Funding the future with the future of currency

**About the Einsteinium Foundation** The Einsteinium Foundation was created to help, in any small way it can, raise funding for cutting edge scientific research. To this aim we created Einsteinium, a new crypto currency (similar to Bitcoin), to gather funds that can be distributed to projects the community chooses. Combined with donations from the community at large we will help fund some of the most innovative projects currently under-way or help seed those waiting to start.

What we can learn from Litecoin falling out of Top10

So as LTC is dropping out of Top10 coins on cmc for the first time (currently sitting at 12) I think it is time to get some insights out of its demise.
Many people in crypto community (especially here in btc) know that LTC is, while not being an outright shitcoin, basically a useless coin. The advantages it had over BTC were really small for most of its lifetime (except for BTC high fee times), and compared to most other alts it was inferior. It had no roadmap other than being a testing ground for BTC and backporting their changes. But what it had, was a clever marketing or "story to tell". Litecoin is silver to BTC's gold. With this simple marketing trick it managed to closely align it to Cryptos biggest Community (BTC) and also paved the way for the greatest dogma in crypto that developed over the years: that Bitcoin is not meant to be spend BTC rather hoarded like gold and if you need to make actual crypto payment you do it with Litecoin.
This marketing ensured that LTC could stay in Top10 for almost a decade, whereas other coins out of the 2011-2013 copycat altcoin era, even some that provided actual advantage (think of Peercoin for example) have long been forgotton.
So what can we learn from this? In crypto community there is a lot of joking about the market being irrational, shitcoins like IOTA which do not even work having the same price development as legit projects, useless projects pumping like mad because they spend all their ICO money on marketing, sentiments like "the market can stay longer irrational than you can solvent" and so and so on. In the case of LTC it is now possible to quantify how long the market can stay irrational in extreme cases: Almost a decade. Measured in crypto time frames almost an eternity, but not a lifespan.
Also important to note is that Litecoin compared to BCH has (even before their current artificial increase) better onchain stats regarding transaction count, active adresses etc. Nevertheless the gap between the coins continues to widen. The market DOES price in tech, future outlook, roadmap and things alike.
So in conclusion: 1. Marketing is extremely important and can outweigh actual tech and roadmap in the short and mid-term (up to 8 years in extreme cases), but not in the long term. 2. Community sentiment can have tremendous impact, just because LTC aligned closely with BTC community they managed to survive much longer than similiar projects from the era. 3. Over time the market does take into account future perspective and outlook.
BCH should take steps accordingly, continue to invest in solid and novel tech, but also increase its reputation in the wider crypto community (pro tip: not constantly shitting on other projects help). In a few years we can earn the fruit of it.
Another thing that came to my mind is that crypto market actually works the direct opposite of current stock market. In crypto, everything changes super fast but the actual market elements to work (valuing fundamental value, expectation trading) takes ages. In stock market (if you look at Tesla for example) things go way slower but basic market functions are comparably quicker (as seen in Tesla having better stock than other car manufacturers, despite being arguably profitable and delivering much less cars, but what matters is actual tech and future expectations).
What do you think of the analysis?

Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

Failure, Chaos, & Bad Decisions: Why Dash's Horrible 2019 Means It Won't Survive 2020

I. Failure
In 2019, LATAM scammers ripped off Dash's treasury for 1000s of coins while providiing fake adoption statistics and embezzling money intended to save poor starving Venezuelan babies.
In 2019, Dash continued its free fall in marketcap rank, plunging to 27 from a high of 3. Once 5 times Monero's marketcap, Dash is by global free market consensus now valued at less than 50% of Monero, and may soon succumb to DogeCoin, a joke currency based on a dead 2013 meme. Measrued against the standard for altcoins, the once-hopeful 2 ETH for 1 Dash rate has surrendered unconditionally to Dash-breaking bearwhales - 1 Dash is worth less than 1/3 of an ETH now.
In 2019, Dash shills tried changing the subject from the "existential crisis" caused by DCG's failed Evolution Roadmap to other coins' cryptowinter vacations or fake & gamed metrics like tx/day, ignoring the obvious fact that Dash's singularly weak fundamentals and price collapsed in terms of Bitcoin, gold, fiat, and all other Top 25 altcoins.
In 2019, Dash shamefully abandoned tried-and-true Nakamoto Consensus with a cheap, gimmicky "Chainlocks" version of Peercoin's good old-fashioned checkpoints.
In 2019, Dash Core's chosen PR firm, Shift Communications, was a huge disappointment as it failed to engage the community, mitigate public relations disasters like MooCowMoo, or direct attention to EvoNet Platform's Open House. Dash Core also suffered the humiliation of being forced to de-endorse their own Shift Communication proposal, asking MNOs to vote down yet another money-wasting, bloated-corporation-imitating Core brainchild.
In 2019, Dash's identity as "Shitcoin of the year" was confirmed after being called out as a scam by the Crypto Vigilante Group due to the instamine, centralized mangement+control, and slow+broken privacy.
In 2019, Dash's support from Jeff Berwick's Dollar Vigilante Group turned very bearish to to their increased awareness of Dash's instamine and broken privacy.
In 2019, Dash was listed by Coinbase, raising hopes the Number might Go Up. But nobody actually cared about Dash on Coinbase, so nothing happened afterwards to change the market's opinion that Dash is worth less than a cold sack of puke.
In 2019, Dash's PrivateSend feature-cum-liability was broken by crypto research specialist u/Flenst, just as many exchanges were delisting Dash beause of its prior marketing under the old Darkcoin brand.
II Chaos
In 2019, every week wealthy Masternode owners dumped their 7200 "free" Dash, without returning anything for it to Dash's primary buyers. As the compounded Instamine Masternode poopulation grew, the market's ability to bear that overhead simply imploded.
In 2019, Dash went from weak to weaker as falling prices and severe reputation damage thanks to Macrochip & Moocowmoo resulted in budget shortfalls for Core Group Inc, intensifing toxic conflict over who must suffer additional austerity measures. Meanwhile Dash's competitors had great years and their devs wrote AND SHIPPED amazing code, such as Cardano releasing its (absolute madhouse of an) Incentivized Shelley Staking Testnet, Monero putting RandomX into production, and Decred adding state-of-the-art CoinShuffle++.
In 2019, DASH became a nightmare of change discussion and negativity. Instead of an Evolution product demo at the Open House, CEO Ryan Taylor plopped out a FUD turd and then proceded to roll around in it while all 15 people watching recoiled in horror and disgust. Markets hate uncertainty, so Dash Core's confusing new mission of endless scope creep, bikeshedding, and self re-invention only exacerbated existing negative investor sentiment.
III Bad Decisions
In 2019, Dash's increasinly desperate and centralized management+control (AKA spork-key hodler) entity, DCG, having lost hope in ever being competitive with successfull PoW-backed hard money cryptoassets like BTC/LTC/XMR, annouced a shocking, narrative-abandoning pivot to exploring Proof Of Stake options (as well as stripping X11 miners of their fair share of coinbase asset allocation).
In 2019, Dash's CEO ruined the years-overdue Evolution Open House by inciting a massive, controversial discussion after unilaterally declaring Dash is "overpaying" for Nakamoto Consensus PoW security.
In 2019, Dash's long-awaited Evolution release Open House featured no actual product demo as Liz's embarrassingly cringe EvoNet slideshow openly annouced Evolution has devolved into a Zero-Calorie Nothingburger with Vaporware Fries and Lite Ketchup.
In 2019, Dash's established coinbase reward allocation and PoW/PoSe consensus mechanism degenerated into a discussion of which Calvinhash Protocol[1] would fix Dash's massive technical and cultural debt problems, thereby making its Number Go Up.
[1] Calvinhash is a protocol invented by Evan at Dash Labs during an especially intense and lavishly provisioned Psytrance party "research" experience/experiment. Calvinhash has no rules; the miners, stakers, and Instamined DCG Masternodes make up their own rules as they go along, ensureing no Calvinhash proof-of-work, block size limit, consensus mechanism, or block reward is like another.

Proof Of Stake

Proof Of Stake
https://preview.redd.it/7nfccptuway41.png?width=1200&format=png&auto=webp&s=0103130266549ba8ae21e63d837b67528e39f59c
In my previous article, I have covered one of the most famous consensus mechanism i.e Proof of Work. But like any technology, that protocol also has a certain drawback, and to overcome these issues another protocol has been developed i.e Proof Of Stake.
Proof Of Stake, as the name implies depends upon the stake of a validator. Like Miners in PoW, PoS consists of a group of validators. These validators use a pseudo-random algorithm to select a node that will act as a validator for the next block. The validator was decided based on a combination of different factors which includes the staking age and the node’s wealth. This means that the more coin one has, the more mining power he or she will have. Thus unlike PoW which is quite a power extensive because it depends upon solving a complex computational puzzle to decide the next block, the validation and generation of next block in PoS solely depend on the owner's stake. In Proof of Stake systems, the blocks that were mined are termed as ‘forged’.
This algorithm was introduced in 2011 with the idea to solve the problems with Proof of Work. Though both these algorithm is used to achieve consensus in the blockchain network, the underlying process to reach the final goal is different.
Some of the crypto coins like Nxt (NXT), Blackcoin, ShadowCoin, and Peercoin (PPC) uses the PoS method. Ethereum (ETH) is also planning to switch to a PoS system.
How do PoS works?
The blockchain network consists of a series of a node which acts as a miner (Forge in this case). Any network user who wants to participate in the forging activity needs to stake a certain amount of coin into the network. One can do this by sending a special transaction that will lock up their base cryptocurrency(in Ethereum's case, ether). The stake size determines the chances of a node to be selected as the next validator who will forge the next block. The bigger the stake, the higher the chances.
The newly created node which got selected to forge the next block checks the validity of the transactions in the block. If the transactions are valid, it then signs the block and adds it to the blockchain network. The node receives the transaction fees that are associated with the transactions in the block as a reward.
In the case when the node doesn’t want to serve as a forger, it can withdraw its stake along with the rewards earned. The network verifies and releases the node once it successfully checks that the node has not been involved in any malicious activity.
Advantages of using PoS:-
o Enhanced security.
o Energy-efficient.
o Reduced risk of centralization.
Forge selection method:-
Two unique methods are being used in case there is a requirement of not selecting the node with the maximum stake. These are:-
o Randomized Block Selection
In this method, a node gets selected as the validators which are having a combination of the lowest hash value and the highest stake. The account which will receive the right to forge a block can be easily predicted by each node because the stakes are public
o Coin Age Selection method
In this method, a node gets selected as the validators who have kept their stake for a longer period. The Coin age is calculated by multiplying the number of days the coins have been reserved as stake by the number of coins that are available as stake.
Coin age=no.of days coined staked *total no of coins staked
The coin age of a node has been reset to zero once it forged a block. To forge another block, the node has to wait for a certain period. Hence this method prevents the large stake nodes from dominating the blockchain network.
Different types of PoS
Proof Of Stake can be categorized into two parts:-
o Chain-based proof of stake
This algorithm randomly selects a validator during the time slot (e.g. every period of 10 seconds might be a time slot) available to create a block, and then assign it an authority to create a block with the constraint that the block must point to some previous block. Generally, it points to the last block of the longest chain. Hence over time, the blocks converge into one growing chain.
Blockchain projects that implemented this model are Nxt, Peercoin, Ardor.
o BFT-style proof of stake
This model offers ‘consistency’. Here the randomly chosen validators decide whether a particular block can be included in the chain or not at the end of each round. This type could be favored for a more “permission” approach. In this case, the consensus on a block does not depend on the length or size of the chain.
Blockchain projects that implemented this model are Neo, Tendermint, Polkadot, Hyperledge Fabric.
How it reduces the risk of a Network attack?
Since this model works on the concept of the stake owned by the validator, thus to effectively control the network and approve fraudulent transactions, a node has to own a majority stake in the network (also known as the 51% attack) which is quite impractical because if a hacker tries to purchase 51% of the total number of coins, the market reacts by the fast price appreciation.
Also, wherever the network detects any fraudulent transaction, not only the forger node loses a part of its stake but is also restricted from participating in future activities. Till the time the cost of staking is higher than the reward, the validator is at a loss in case of attempting fraud.
With the “Casper” upgrade underway for Ethereum, Proof-of-Stake (POS) model is gaining more popularity among other Blockchain consensus designs. With this upgrade, the protocols will set certain criteria that will identify a bad validator. The bad validator would lose their deposit if proven, thus making this model more secure.

Instant Crypto Exchange Flyp.me Adds USD Coin (USDC) Stablecoin Cryptocurrency

We've done it again and added another major addition to our already stacked digital asset offerings! USD Coin (USDC), a Coinbase-developed stablecoin with big backing from some of the crypto world’s biggest names, is now tradable on Flyp.me.
This addition gives Flyp.me users a major leg up in the ever-important quest for digital asset liquidity and mobility. Want to send your stablecoin balance between Flyp.me and Coinbase? No problem! How about sending USDC to Binance through Flyp.me? Easy.
Best of all, Flyp.me does not require an account to trade USDC. The process for grabbing some USDC with Flyp.me couldn’t be easier.
At no point do you enter your private keys, or give any information other than your public wallet address. So, what makes the USDC stablecoin special compared to other stable cryptocurrencies out there like Tether (USDT)? Here is a quick overview of USDC stablecoin and why this one is truly a game-changer for current and future Flyp.me traders.
USDC — Not Your Average Stablecoin
Of all the brand names in the cryptocurrency industry, few are as well known — or completely trusted — as Coinbase is. Yes, Coinbase is one of Flyp.me’s direct competitors, but you know what? Credit goes where credit is due.
Coinbase partnered with Circle to bring about USD Coin, 1:1 USD-backed cryptocurrency that stays true to its $1 = 1 USDC value. How does that work? Essentially, Coinbase keeps $1 in the bank for every 1 USDC in circulation, tying each coin to real — not imaginary or inflated — financial value.
Sure, there are other stablecoins out there, but few of them are audited, and even fewer come with the guarantee that only a big name like Coinbase can provide. USDC provides some welcome relief by being, well, stable.
USDC Stablecoin Is Powered by Ethereum
Another major plus USDC has going is it’s powered by Ethereum, our favorite decentralized ledger for all things DeFi (decentralized finance). As the undisputed hub of the emerging DeFi economy, Ethereum has nearly $1 billion in value locked into the blockchain.
Being Ethereum-based makes the ERC-20 standard USDC coin easily transferable between you and other crypto users, or from your wallet to exchanges. This ease of transfer is especially handy when you need to make a move quickly — unlike the Bitcoin blockchain, Ethereum tends to be quicker.
If you’re ready to trade some USDC cryptocurrency without the hassle of creating an account, then head over to Flyp.me and get started now!
About Flyp.me

Nuv mining | Can You Creat a Ton Of Money Via Bitcoin Mining?

Consumers, investors, fanatics or even technology smart geeks may be wonderful Bitcoin enthusiasts. They can even follow all Bitcoin information as well as have a solitary inquiry in mind. People might simply want to figure out, whether an optimistic future can be taken of mining different cryptocurrencies. Well, it's not a trick or stunning paid announcement. Mining of cryptocurrencies can be a smart step, aside from being a financially rewarding one. And also the appeal of Bitcoin market can not be denied as well. The Bitcoin boom of 2013 and its huge rise in value brought about its reputation. The roller-coaster ride of Bitcoin as well as the other cryptocurrencies, called as Altcoins, discovered a location of reputation in each dictionary of the world. Digital currencies have actually earned adequate direct exposure, and a mining occupation including them can really supply earnings. The miners nevertheless, have to have three points - adequate time, adequate money and an unequaled perseverance.
nuv mining
The initial hurdle involves the option of a cryptocurrency. A fanatic can go on to mine Bitcoin. Or instead pick to extract other readily available cryptocurrencies, Dogecoin, Litecoin or Peercoin. In other words, miners have a lot of options. Comparable to stock, even cryptocurrencies have classifications, blue chip or dime. Mining the blue chip category is commonly associated with security, integrity and a greater amount of profit. Financial on these attributes, individuals are much more inclined towards Bitcoin mining, even if it includes utilizing an enormous computer power. Altcoins, on the other hand, can also offer a fair gain as algorithms are less complex. However with Altcoins, simplicity of mining as well as the potential gains are not always proportional.
nuvmining
Hardware is an element that begins to disclose the real examination. Also a techno-savvy miner can not refute the Bitcoin problem linked to brand-new block generation. The point is to decide upon the computing power to be used. For Bitcoins, algorithms have come to be difficult to hash. Thus, GPUs of gigantic power combined with high-end RAMs and also reputable hard disk drives have to do all the task. The point is to hash at a quick price. Several high-end GPUs running together can speed up block generation and also consequently the payouts. On the various other hand, picking an item of software could not be as tricky. Windows can be selected as the required OS, yet open-source Linux does a far better job. One more demand is a digital wallet. Extracted money have to be kept. One can keep it locally on hard-drive or remotely online. A miner just has to select wisely.
With hardware and software in position, the task of mining begins. A miner may do it all alone, as well as collect all advantages. However the gear has to be tremendously effective. So it's fairly doubtful. Mining pools appear to be a sensible solution as people team up to contribute hash power and makers. Thus coins obtain extracted at a great speed. Collaborating has its advantages; miners get their reasonable share. Multipool is an economical choice. If Altcoin mining is to be embarked on, Middlecoin should be the miner's choice. So with all the active ingredients in place, a profitable mining gear can start. First investment may seem overwhelming, however the earnings are worthwhile!

A brief history of the 2013 market peak; why some alts really do die; and what would've happened if you'd given in to FOMO

This piece is a follow-up to my earlier piece, which looked at what would’ve happened if you’d purchased alt-coins shortly after the bottom of the 2013-2015 bear market. A lot of the constructive criticism that I received was that I was too bullish on alt-coins, and that the timing was too convenient. Although it’s fair to say that I am bullish on crypto in general and alt-coins in particular (with several major caveats for both), I agree that it’s important to not just focus on historical analyses where it’s fairly clear that you could have earned money. So, today’s research question is whether you’d still be underwater if you’d bought in to the market at or near the 2013 all-time high. All information cited herein comes from the historical charts available at CoinMarketCap.
TL;DR: This worst-case scenario analysis shows that $300 invested equally across 15 of the 40 coins in existence near the market’s peak in 2013 would be worth only $429.95 today—gains which are entirely attributable to Bitcoin, Litecoin, and Ripple. This is basic, but it can be dangerous to buy high. This is especially true of alt-coins, but even the top three coins in our sample saw fairly lackluster results when bought at the top of the market. Finally, nothing in this post should be taken as investment advice. This is only intended as historical analysis. Past performance does not guarantee future returns.
A Brief History of the 2013 Market Peak
According to CoinMarketCap, the 2013 bull market peaked on December 4, 2013, at ~$15.87 billion in market capitalization.* Thereafter, the market crashed dramatically not once, but twice. In the first crash, which occurred between December 5-8, 2013, overall market cap fell by ~39% to ~$9.66 billion. Then, after a brief recovery to ~$13.57 billion on December 10th, the market fell precipitously, to ~$5.7 billion on December 18, 2013. Thus, over the course of only two weeks, from December 4-18, 2013, the market lost ~64% of its value. Although this was by no means the end of the 2013-2015 bear market--which lasted for approximately 17 months and saw an additional decline of ~45% from the December 18, 2013 low--this was the end of the beginning.
What If I Bought Crypto Right as the 2013 Market Peaked?
Generally, the first rule of trading is** that you want to buy low and sell high. As a result of their fear of missing out (“FOMO”), however, many people find themselves accidentally buying high. Today, I’m going to look at what would have happened to someone who bought their crypto right as the market was peaking. Ideally, I would run this experiment from December 4, 2013, but due to the limited data available from CoinMarketCap, I’m forced to choose between November 24th, December 1st, December 8th, and December 15th. Of those dates, I have selected December 1, 2013, because it represents the worst possible scenario for which I have data. On that date, total crypto market cap, which had hit a new high of ~$15.4 billion the day before, swung wildly between a high of ~$14.83 billion and a low of ~$12.18 billion. Unfortunately, it’s unclear exactly when CoinMarketCap’s snapshot was taken. That said, it’s clear that our hypothetical FOMO trader is about to lose his shirt over the next few weeks, so let’s dive into the specifics.
On December 1, 2013, there were 40 coins listed on CoinMarketCap. I won’t list them all here, but of those 40, all but 11 are still listed as active on CoinMarketCap. The truly dead (or “inactive”) coins are BBQCoin (BQC; rank 16), Devcoin (DVC; rank 19), Tickets (TIX; rank 22), Copperlark (CLR; rank 24), StableCoin (SBC; rank 25), Luckycoin (LKY—ironic, I realize; rank 31), Franko (FRK; rank 34), Bytecoin (BTE; rank 35), Junkcoin (JKE—how apt; rank 36), CraftCoin (CRC; rank 39), and Colossuscoin (COL; rank 40).***
Now, since this post is already incredibly long, instead of testing all 40 coins, let’s take a decently-sized sample of five coins each from the top, middle, and bottom of the stack, and look at what happens. For the middle, although the temptation is to take decent alts, let’s fight that and take the group with the highest failure rate: ranks 21-25. So, here’s out pool:
Now, here are how our sample of coins has performed as of when I write this:****
So, if our hypothetical FOMO trader had invested $100 in our top-five sample near the 2013 peak, it would currently be worth $411.80 (the profitable coins) + $3.06 (PPC) + $4.27 (NMC) = $419.13—a 4.19x increase.
Now for the two coins in the middle five that didn’t completely die:
So, if our hypothetical FOMO trader had invested $100 in our middle-five sample near the 2013 peak, it would currently be worth ~$15.19—an ~84.8% loss.
Finally, here are the two coins from the bottom five that didn’t completely die:
So, excluding everything buy Argentum, if our hypothetical FOMO trader had invested $100 in our bottom-five sample near the 2013 peak, it would currently be worth ~$2.96—a ~97% loss. Putting it all together, $300 invested in this sample of 15 coins as close to the peak of the 2013 market as the data will let me get, would be worth $429.95—a disappointing, but not-unexpected ~30.2% increase over five years. That said, I’m honestly somewhat amazed our FOMO trader made anything at all on this basket of coins, considering how many of them failed. In any case, all of his gains came from the top-three coins from 2013: Bitcoin, Litecoin, and Ripple.
Conclusions
What’s the lesson here, what’s the takeaway?***** Most importantly, I think the above analysis shows that it can be very dangerous to buy alt-coins when the market is at or near an all-time high—a conclusion that appears to be true regardless of where the alt is positioned in the market. That said, there are a few caveats: (1) this sample was intentionally bad, in order to reflect a worst-case scenario; (2) even buying the top-three coins at the all-time high didn’t net our FOMO trader particularly large gains when compared to someone who bought these same coins after the crash. Therefore, I think that the most important lesson here is not to buy high in the first place. Investing solely because of FOMO will probably cause you to lose money, unless you have invested equally in a broad range of cryptocurrencies, like the trader in our hypothetical. Even then, however, our FOMO trader probably would have done better investing in an S&P Index fund over the same period.
Endnotes
*This is a correction to my earlier piece, in which I stated that the cryptocurrency market peaked on November 30, 2013, at a total market capitalization of ~$15.2 billion. I made this error due to having failed to narrow the date range of the chart so I could properly zoon in. That said, the exact details of the market peak don’t affect the conclusions from my last piece, which considered trades made after the market had bottomed out.
** …you do not talk about trading. Wait, that’s the wrong rulebook.
*** Since I already typed it out, here’s the list of remaining active coins, in descending order: Bitcoin (BTC), Litecoin (LTC), Ripple (XRP), Peercoin (PPC), Namecoin (NMC), Megacoin (MEC), Feathercoin (FTC), WorldCoin (WDC), Primecoin (XPM), Freicoin (FRC), Novacoin (NVC), Zetacoin (ZET), Infinitecoin (IFC), Terracoin (TRC), Crypto Bullion (CBX), Anoncoin (ANC), Digitalcoin (DGC), GoldCoin (GLD), Yacoin (YAC), Ixcoin (IXC), Fastcoin (FST), BitBar (BTB), Mincoin (MNC), Tagcoin (TAG), FlorinCoin (FLO), I0Coin (I0C), Phoenixcoin (PXC), Argentum (ARG), Elacoin (ELC)
**** I know that we could have sold them sooner, and probably for more money, but let’s just assume that our hypothetical FOMO trader was a founding member of the #hodlgang. ;-)
***** Don’t mess with Maui when he’s on a breakaway! You’re welcome. ;-)
Disclosures: I have previous held Litecoin, and currently hold approximately $140 of Ripple. I do not believe this influenced my analysis in any way. I have never bought or held any of the other coins discussed in this analysis.

Consensus Algorithms

[Proof of Work] - very short, cuz it's well-known.
[1] Bitcoin - to generate a new block miner must generate hash of the new block header that is in line with given requirements.
Others: Ethereum, Litecoin etc.
[Hybrid of PoW and PoS]
[2] Decred - hybrid of “proof of work” and “proof of stake”. Blocks are created about every 5 minutes. Nodes in the network looking for a solution with a known difficulty to create a block (PoW). Once the solution is found it is broadcast to the network. The network then verifies the solution. Stakeholders who have locked some DCR in return for a ticket* now have the chance to vote on the block (PoS). 5 tickets are chosen pseudo-randomly from the ticket pool and if at least 3 of 5 vote ‘yes’ the block is permanently added to the blockchain. Both miners and voters are compensated with DCR : PoS - 30% and PoW - 60% of about 30 new Decred issued with a block. * 1 ticket = ability to cast 1 vote. Stakeholders must wait an average of 28 days (8,192 blocks) to vote their tickets.
[Proof of Stake]
[3] Nxt - The more tokens are held by account, the greater chance that account will earn the right to generate a block. The total reward received as a result of block generation is the sum of the transaction fees located within the block. Three values are key to determining which account is eligible to generate a block, which account earns the right to generate a block, and which block is taken to be the authoritative one in times of conflict: base target value, target value and cumulative difficulty. Each block on the chain has a generation signature parameter. To participate in the block's forging process, an active account digitally signs the generation signature of the previous block with its own public key. This creates a 64-byte signature, which is then hashed using SHA256. The first 8 bytes of the resulting hash are converted to a number, referred to as the account hit. The hit is compared to the current target value(active balance). If the computed hit is lower than the target, then the next block can be generated.
[4] Peercoin (chain-based proof of stake) - coin age parameter. Hybrid PoW and PoS algorithm. The longer your Peercoins have been stationary in your account (to a maximum of 90 days), the more power (coin age) they have to mint a block. The act of minting a block requires the consumption of coin age value, and the network determines consensus by selecting the chain with the largest total consumed coin age. Reward - minting + 1% yearly.
[5] Reddcoin (Proof of stake Velocity) - quite similar to Peercoin, difference: not linear coin-aging function (new coins gain weight quickly, and old coins gain weight increasingly slowly) to encourage Nodes Activity. Node with most coin age weight have a bigger chance to create block. To create block Node should calculate right hash. Block reward - interest on the weighted age of coins/ 5% annual interest in PoSV phase.
[6] Ethereum (Casper) - uses modified BFT consensus. Blocks will be created using PoW. In the Casper Phase 1 implementation for Ethereum, the “proposal mechanism" is the existing proof of work chain, modified to have a greatly reduced block reward. Blocks will be validated by set of Validators. Block is finalised when 2/3 of validators voted for it (not the number of validators is counted, but their deposit size). Block creator rewarded with Block Reward + Transaction FEES.
[7] Lisk (Delegated Proof-of-stake) - Lisk stakeholders vote with vote transaction (the weight of the vote depends on the amount of Lisk the stakeholder possess) and choose 101 Delegates, who create all blocks in the blockchain. One delegate creates 1 block within 1 round (1 round contains 101 blocks) -> At the beginning of each round, each delegate is assigned a slot indicating their position in the block generation process -> Delegate includes up to 25 transactions into the block, signs it and broadcasts it to the network -> As >51% of available peers agreed that this block is acceptable to be created (Broadhash consensus), a new block is added to the blockchain. *Any account may become a delegate, but only accounts with the required stake (no info how much) are allowed to generate blocks. Block reward - minted Lisks and transaction fees (fees for all 101 blocks are collected firstly and then are divided between delegates). Blocks appears every 10 sec.
[8] Cardano (Ouroboros Proof of Stake) - Blocks(slots) are created by Slot Leaders. Slot Leaders for N Epoch are chosen during n-1 Epoch. Slot Leaders are elected from the group of ADA stakeholders who have enough stake. Election process consist of 3 phases: Commitment phase: each elector generates a random value (secret), signs it and commit as message to network (other electors) saved in to block. -> Reveal phase: Each elector sends special value to open a commitment, all this values (opening) are put into the block. -> Recovery phase: each elector verifies that commitments and openings match and extracts the secrets and forms a SEED (randomly generated bytes string based on secrets). All electors get the same SEED. -> Follow the Satoshi algorithm : Elector who have coin which corresponded to SEED become a SLOT LEADER and get a right to create a block. Slot Leader is rewarded with minted ADA and transactions Fee.
[9] Tezos (Proof Of Stake) - generic and self-amending crypto-ledger. At the beginning of each cycle (2048 blocks), a random seed is derived from numbers that block miners chose and committed to in the penultimate cycle, and revealed in the last. -> Using this random seed, a follow the coin strategy (similar to Follow The Satoshi) is used to allocate mining rights and signing rights to stakeholders for the next cycle*. -> Blocks are mined by a random stakeholder (the miner) and includes multiple signatures of the previous block provided by random stakeholders (the signers). Mining and signing both offer a small reward but also require making a one cycle safety deposit to be forfeited in the event of a double mining or double signing.
· the more coins (rolls) you have - the more your chance to be a minesigner.
[10] Tendermint (Byzantine Fault Tolerance) - A proposal is signed and published by the designated proposer at each round. The proposer is chosen by a deterministic and non-choking round robin selection algorithm that selects proposers in proportion to their voting power. The proposer create the block, that should be validated by >2/3 of Validators, as follow: Propose -> Prevote -> Precommit -> Commit. Proposer rewarded with Transaction FEES.
[11] Tron (Byzantine Fault Tolerance) - This blockhain is still on development stage. Consensus algorithm = PoS + BFT (similar to Tendermint): PoS algorithm chooses a node as Proposer, this node has the power to generate a block. -> Proposer broadcasts a block that it want to release. -> Block enters the Prevote stage. It takes >2/3 of nodes' confirmations to enter the next stage. -> As the block is prevoted, it enters Precommit stage and needs >2/3 of node's confirmation to go further. -> As >2/3 of nodes have precommited the block it's commited to the blockchain with height +1. New blocks appears every 15 sec.
[12] NEO (Delegated Byzantine Fault Tolerance) - Consensus nodes* are elected by NEO holders -> The Speaker is identified (based on algorithm) -> He broadcasts proposal to create block -> Each Delegate (other consensus nodes) validates proposal -> Each Delegate sends response to other Delegates -> Delegate reaches consensus after receiving 2/3 positive responses -> Each Delegate signs the block and publishes it-> Each Delegate receives a full block. Block reward 6 GAS distributed proportionally in accordance with the NEO holding ratio among NEO holders. Speaker rewarded with transaction fees (mostly 0). * Stake 1000 GAS to nominate yourself for Bookkeeping(Consensus Node)
[13] EOS (Delegated Proof of Stake) - those who hold tokens on a blockchain adopting the EOS.IO software may select* block producers through a continuous approval voting system and anyone may choose to participate in block production and will be given an opportunity to produce blocks proportional to the total votes they have received relative to all other producers. At the start of each round 21 unique block producers are chosen. The top 20 by total approval are automatically chosen every round and the last producer is chosen proportional to their number of votes relative to other producers. Block should be confirmed by 2/3 or more of elected Block producers. Block Producer rewarded with Block rewards. *the more EOS tokens a stakeholder owns, the greater their voting power
[The XRP Ledger Consensus Process]
[14] Ripple - Each node receives transaction from external applications -> Each Node forms public list of all valid (not included into last ledger (=block)) transactions aka (Candidate Set) -> Nodes merge its candidate set with UNLs(Unique Node List) candidate sets and vote on the veracity of all transactions (1st round of consensus) -> all transactions that received at least 50% votes are passed on the next round (many rounds may take place) -> final round of consensus requires that min 80% of Nodes UNL agreeing on transactions. It means that at least 80% of Validating nodes should have same Candidate SET of transactions -> after that each Validating node computes a new ledger (=block) with all transactions (with 80% UNL agreement) and calculate ledger hash, signs and broadcasts -> All Validating nodes compare their ledgers hash -> Nodes of the network recognize a ledger instance as validated when a 80% of the peers have signed and broadcast the same validation hash. -> Process repeats. Ledger creation process lasts 5 sec(?). Each transaction includes transaction fee (min 0,00001 XRP) which is destroyed. No block rewards.
[The Stellar consensus protocol]
[15] Stellar (Federated Byzantine Agreement) - quite similar to Ripple. Key difference - quorum slice.
[Proof of Burn]
[16] Slimcoin - to get the right to write blocks Node should “burn” amount of coins. The more coins Node “burns” more chances it has to create blocks (for long period) -> Nodes address gets a score called Effective Burnt Coins that determines chance to find blocks. Block creator rewarded with block rewards.
[Proof of Importance]
[17] NEM - Only accounts that have min 10k vested coins are eligible to harvest (create a block). Accounts with higher importance scores have higher probabilities of harvesting a block. The higher amount of vested coins, the higher the account’s Importance score. And the higher amount of transactions that satisfy following conditions: - transactions sum min 1k coins, - transactions made within last 30 days, - recipient have 10k vested coins too, - the higher account’s Important score. Harvester is rewarded with fees for the transactions in the block. A new block is created approx. every 65 sec.
[Proof of Devotion]
[18] Nebulas (Proof of Devotion + BFT) - quite similar to POI, the PoD selects the accounts with high influence. All accounts are ranked according to their liquidity and propagation (Nebulas Rank) -> Top-ranked accounts are selected -> Chosen accounts pay deposit and are qualified as the blocks Validators* -> Algorithm pseudo-randomly chooses block Proposer -> After a new block is proposed, Validators Set (each Validator is charged a deposit) participate in a round of BFT-Style voting to verify block (1. Prepare stage -> 2. Commit Stage. Validators should have > 2/3 of total deposits to validate Block) -> Block is added. Block rewards : each Validator rewarded with 1 NAS. *Validators Set is dynamic, changes in Set may occur after Epoch change.
[IOTA Algorithm]
[19] IOTA - uses DAG (Directed Acyclic Graph) instead of blockchain (TANGLE equal to Ledger). Graph consist of transactions (not blocks). To issue a new transaction Node must approve 2 random other Transactions (not confirmed). Each transaction should be validate n(?) times. By validating PAST(2) transactions whole Network achieves Consensus. in Order to issue transaction Node: 1. Sign transaction with private key 2. choose two other Transactions to validate based on MCMC(Markov chain Monte Carlo) algorithm, check if 2 transactions are valid (node will never approve conflicting transactions) 3. make some PoW(similar to HashCash). -> New Transaction broadcasted to Network. Node don’t receive reward or fee.
[PBFT + PoW]
[20] Yobicash - uses PBFT and also PoW. Nodes reach consensus on transactions by querying other nodes. A node asks its peers about the state of a transaction: if it is known or not, and if it is a doublespending transaction or not. As follow : Node receives new transaction -> Checks if valid -> queries all known nodes for missing transactions (check if already in DAG ) -> queries 2/3 nodes for doublepsending and possibility -> if everything is ok add to DAG. Reward - nodes receive transaction fees + minting coins.
[Proof of Space/Proof of Capacity]
[21] Filecoin (Power Fault Tolerance) - the probability that the network elects a miner(Leader) to create a new block (it is referred to as the voting power of the miner) is proportional to storage currently in use in relation to the rest of the network. Each node has Power - storage in use verified with Proof of Spacetime by nodes. Leaders extend the chain by creating a block and propagating it to the network. There can be an empty block (when no leader). A block is committed if the majority of the participants add their weight on the chain where the block belongs to, by extending the chain or by signing blocks. Block creator rewarded with Block reward + transaction fees.
[Proof of Elapsed Time (POET)]
[22] Hyperledger Sawtooth - Goal - to solve BFT Validating Nodes limitation. Works only with intel’s SGX. PoET uses a random leader election model or a lottery based election model based on SGX, where the protocol randomly selects the next leader to finalize the block. Every validator requests a wait time from an enclave (a trusted function). -> The validator with the shortest wait time for a particular transaction block is elected the leader. -> The BlockPublisher is responsible for creating candidate blocks to extend the current chain. He takes direction from the consensus algorithm for when to create a block and when to publish a block. He creates, Finalizes, Signs Block and broadcast it -> Block Validators check block -> Block is created on top of blockchain.
[23] Byteball (Delegated Byzantine Fault Tolerance) - only verified nodes are allowed to be Validation nodes (list of requirements https://github.com/byteball/byteball-witness). Users choose in transaction set of 12 Validating nodes. Validating nodes(Witnesses) receive transaction fees.
[24] Nano - uses DAG, PoW (HashCash). Nano uses a block-lattice structure. Each account has its own blockchain (account-chain) equivalent to the account’s transaction/balance history. To add transaction user should make some HashCash PoW -> When user creates transaction Send Block appears on his blockchain and Receive block appears on Recipients blockchain. -> Peers in View receive Block -> Peers verify block (Double spending and check if already in the ledger) -> Peers achieve consensus and add block. In case of Fork (when 2 or more signed blocks reference the same previous block): Nano network resolves forks via a balance-weighted voting system where representative nodes vote for the block they observe, as >50% of weighted votes received, consensus achieved and block is retained in the Node’s ledger (block that lose the vote is discarded).
[25] Holochain - uses distributed hash table (DHT). Instead of trying to manage global consensus for every change to a huge blockchain ledger, every participant has their own signed hash chain. In case of multi-party transaction, it is signed to each party's chain. Each party signs the exact same transaction with links to each of their previous chain entries. After data is signed to local chains, it is shared to a DHT where every neighbor node validate it. Any consensus algorithms can be built on top of Holochain.
[26] Komodo ('Delegated' Delayed Proof of Work (dPoW)) - end-to-end blockchain solutions. DPoW consensus mechanism does not recognize The Longest Chain Rule to resolve a conflict in the network, instead the dPoW looks to backups it inserted previously into the chosen PoW blockchain. The process of inserting backups of Komodo transactions into a secure PoW is “notarization.” Notarisation is performed by the elected Notary nodes. Roughly every ten minutes, the Notary nodes perform a special block hash mined on the Komodo blockchain and take note of the overall Komodo blockchain “height”. The notary nodes process this specifc block so that their signatures are cryptographically included within the content of the notarized data. There are sixty-four “Notary nodes” elected by a stake-weighted vote, where ownership of KMD represents stake in the election. They are a special type of blockchain miner, having certain features in their underlying code that enable them to maintain an effective and cost-efcient blockchain and they periodically receives the privilege to mine a block on “easy difculty.”

My brief observation of most common Consensus Algorithms

I have studied most common consensus algorithms. Here is the summary, maybe for someone it will be helpful. My goal is to describe every specific consensus briefly so everyone can easily understand it. *Please let me know if I have wrote something wrong, or maybe you are aware of interesting algorithm, I have missed.
[Proof of Work] - very short, cuz it's well-known.
[1] Bitcoin - to generate a new block miner must generate hash of the new block header that is in line with given requirements.
Others: Ethereum, Litecoin etc.
[Hybrid of PoW and PoS]
[2] Decred - hybrid of “proof of work” and “proof of stake”. Blocks are created about every 5 minutes. Nodes in the network looking for a solution with a known difficulty to create a block (PoW). Once the solution is found it is broadcast to the network. The network then verifies the solution. Stakeholders who have locked some DCR in return for a ticket* now have the chance to vote on the block (PoS). 5 tickets are chosen pseudo-randomly from the ticket pool and if at least 3 of 5 vote ‘yes’ the block is permanently added to the blockchain. Both miners and voters are compensated with DCR : PoS - 30% and PoW - 60% of about 30 new Decred issued with a block. * 1 ticket = ability to cast 1 vote. Stakeholders must wait an average of 28 days (8,192 blocks) to vote their tickets.
[Proof of Stake]
[3] Nxt - The more tokens are held by account, the greater chance that account will earn the right to generate a block. The total reward received as a result of block generation is the sum of the transaction fees located within the block. Three values are key to determining which account is eligible to generate a block, which account earns the right to generate a block, and which block is taken to be the authoritative one in times of conflict: base target value, target value and cumulative difficulty. Each block on the chain has a generation signature parameter. To participate in the block's forging process, an active account digitally signs the generation signature of the previous block with its own public key. This creates a 64-byte signature, which is then hashed using SHA256. The first 8 bytes of the resulting hash are converted to a number, referred to as the account hit. The hit is compared to the current target value(active balance). If the computed hit is lower than the target, then the next block can be generated.
[4] Peercoin (chain-based proof of stake) - coin age parameter. Hybrid PoW and PoS algorithm. The longer your Peercoins have been stationary in your account (to a maximum of 90 days), the more power (coin age) they have to mint a block. The act of minting a block requires the consumption of coin age value, and the network determines consensus by selecting the chain with the largest total consumed coin age. Reward - minting + 1% yearly.
[5] Reddcoin (Proof of stake Velocity) - quite similar to Peercoin, difference: not linear coin-aging function (new coins gain weight quickly, and old coins gain weight increasingly slowly) to encourage Nodes Activity. Node with most coin age weight have a bigger chance to create block. To create block Node should calculate right hash. Block reward - interest on the weighted age of coins/ 5% annual interest in PoSV phase.
[6] Ethereum (Casper) - uses modified BFT consensus. Blocks will be created using PoW. In the Casper Phase 1 implementation for Ethereum, the “proposal mechanism" is the existing proof of work chain, modified to have a greatly reduced block reward. Blocks will be validated by set of Validators. Block is finalised when 2/3 of validators voted for it (not the number of validators is counted, but their deposit size). Block creator rewarded with Block Reward + Transaction FEES.
[7] Lisk (Delegated Proof-of-stake) - Lisk stakeholders vote with vote transaction (the weight of the vote depends on the amount of Lisk the stakeholder possess) and choose 101 Delegates, who create all blocks in the blockchain. One delegate creates 1 block within 1 round (1 round contains 101 blocks) -> At the beginning of each round, each delegate is assigned a slot indicating their position in the block generation process -> Delegate includes up to 25 transactions into the block, signs it and broadcasts it to the network -> As >51% of available peers agreed that this block is acceptable to be created (Broadhash consensus), a new block is added to the blockchain. *Any account may become a delegate, but only accounts with the required stake (no info how much) are allowed to generate blocks. Block reward - minted Lisks and transaction fees (fees for all 101 blocks are collected firstly and then are divided between delegates). Blocks appears every 10 sec.
[8] Cardano (Ouroboros Proof of Stake) - Blocks(slots) are created by Slot Leaders. Slot Leaders for N Epoch are chosen during n-1 Epoch. Slot Leaders are elected from the group of ADA stakeholders who have enough stake. Election process consist of 3 phases: Commitment phase: each elector generates a random value (secret), signs it and commit as message to network (other electors) saved in to block. -> Reveal phase: Each elector sends special value to open a commitment, all this values (opening) are put into the block. -> Recovery phase: each elector verifies that commitments and openings match and extracts the secrets and forms a SEED (randomly generated bytes string based on secrets). All electors get the same SEED. -> Follow the Satoshi algorithm : Elector who have coin which corresponded to SEED become a SLOT LEADER and get a right to create a block. Slot Leader is rewarded with minted ADA and transactions Fee.
[9] Tezos (Proof Of Stake) - generic and self-amending crypto-ledger. At the beginning of each cycle (2048 blocks), a random seed is derived from numbers that block miners chose and committed to in the penultimate cycle, and revealed in the last. -> Using this random seed, a follow the coin strategy (similar to Follow The Satoshi) is used to allocate mining rights and signing rights to stakeholders for the next cycle*. -> Blocks are mined by a random stakeholder (the miner) and includes multiple signatures of the previous block provided by random stakeholders (the signers). Mining and signing both offer a small reward but also require making a one cycle safety deposit to be forfeited in the event of a double mining or double signing. * the more coins (rolls) you have - the more your chance to be a minesigner.
[10] Tendermint (Byzantine Fault Tolerance) - A proposal is signed and published by the designated proposer at each round. The proposer is chosen by a deterministic and non-choking round robin selection algorithm that selects proposers in proportion to their voting power. The proposer create the block, that should be validated by >2/3 of Validators, as follow: Propose -> Prevote -> Precommit -> Commit. Proposer rewarded with Transaction FEES.
[11] Tron (Byzantine Fault Tolerance) - This blockhain is still on development stage. Consensus algorithm = PoS + BFT (similar to Tendermint): PoS algorithm chooses a node as Proposer, this node has the power to generate a block. -> Proposer broadcasts a block that it want to release. -> Block enters the Prevote stage. It takes >2/3 of nodes' confirmations to enter the next stage. -> As the block is prevoted, it enters Precommit stage and needs >2/3 of node's confirmation to go further. -> As >2/3 of nodes have precommited the block it's commited to the blockchain with height +1. New blocks appears every 15 sec.
[12] NEO (Delegated Byzantine Fault Tolerance) - Consensus nodes* are elected by NEO holders -> The Speaker is identified (based on algorithm) -> He broadcasts proposal to create block -> Each Delegate (other consensus nodes) validates proposal -> Each Delegate sends response to other Delegates -> Delegate reaches consensus after receiving 2/3 positive responses -> Each Delegate signs the block and publishes it-> Each Delegate receives a full block. Block reward 6 GAS distributed proportionally in accordance with the NEO holding ratio among NEO holders. Speaker rewarded with transaction fees (mostly 0). * Stake 1000 GAS to nominate yourself for Bookkeeping(Consensus Node)
[13] EOS (Delegated Proof of Stake) - those who hold tokens on a blockchain adopting the EOS.IO software may select* block producers through a continuous approval voting system and anyone may choose to participate in block production and will be given an opportunity to produce blocks proportional to the total votes they have received relative to all other producers. At the start of each round 21 unique block producers are chosen. The top 20 by total approval are automatically chosen every round and the last producer is chosen proportional to their number of votes relative to other producers. Block should be confirmed by 2/3 or more of elected Block producers. Block Producer rewarded with Block rewards. *the more EOS tokens a stakeholder owns, the greater their voting power
[The XRP Ledger Consensus Process]
[14] Ripple - Each node receives transaction from external applications -> Each Node forms public list of all valid (not included into last ledger (=block)) transactions aka (Candidate Set) -> Nodes merge its candidate set with UNLs(Unique Node List) candidate sets and vote on the veracity of all transactions (1st round of consensus) -> all transactions that received at least 50% votes are passed on the next round (many rounds may take place) -> final round of consensus requires that min 80% of Nodes UNL agreeing on transactions. It means that at least 80% of Validating nodes should have same Candidate SET of transactions -> after that each Validating node computes a new ledger (=block) with all transactions (with 80% UNL agreement) and calculate ledger hash, signs and broadcasts -> All Validating nodes compare their ledgers hash -> Nodes of the network recognize a ledger instance as validated when a 80% of the peers have signed and broadcast the same validation hash. -> Process repeats. Ledger creation process lasts 5 sec(?). Each transaction includes transaction fee (min 0,00001 XRP) which is destroyed. No block rewards.
[The Stellar consensus protocol]
[15] Stellar (Federated Byzantine Agreement) - quit similar to Ripple. Key difference - quorum slice.
[Proof of Burn]
[16] Slimcoin - to get the right to write blocks Node should “burn” amount of coins. The more coins Node “burns” more chances it has to create blocks (for long period) -> Nodes address gets a score called Effective Burnt Coins that determines chance to find blocks. Block creator rewarded with block rewards.
[Proof of Importance]
[17] NEM - Only accounts that have min 10k vested coins are eligible to harvest (create a block). Accounts with higher importance scores have higher probabilities of harvesting a block. The higher amount of vested coins, the higher the account’s Importance score. And the higher amount of transactions that satisfy following conditions: - transactions sum min 1k coins, - transactions made within last 30 days, - recipient have 10k vested coins too, - the higher account’s Important score. Harvester is rewarded with fees for the transactions in the block. A new block is created approx. every 65 sec.
[Proof of Devotion]
[18] Nebulas (Proof of Devotion + BFT) - quite similar to POI, the PoD selects the accounts with high influence. All accounts are ranked according to their liquidity and propagation (Nebulas Rank) -> Top-ranked accounts are selected -> Chosen accounts pay deposit and are qualified as the blocks Validators* -> Algorithm pseudo-randomly chooses block Proposer -> After a new block is proposed, Validators Set (each Validator is charged a deposit) participate in a round of BFT-Style voting to verify block (1. Prepare stage -> 2. Commit Stage. Validators should have > 2/3 of total deposits to validate Block) -> Block is added. Block rewards : each Validator rewarded with 1 NAS. *Validators Set is dynamic, changes in Set may occur after Epoch change.
[IOTA Algorithm]
[19] IOTA - uses DAG (Directed Acyclic Graph) instead of blockchain (TANGLE equal to Ledger). Graph consist of transactions (not blocks). To issue a new transaction Node must approve 2 random other Transactions (not confirmed). Each transaction should be validate n(?) times. By validating PAST(2) transactions whole Network achieves Consensus. in Order to issue transaction Node: 1. Sign transaction with private key 2. choose two other Transactions to validate based on MCMC(Markov chain Monte Carlo) algorithm, check if 2 transactions are valid (node will never approve conflicting transactions) 3. make some PoW(similar to HashCash). -> New Transaction broadcasted to Network. Node don’t receive reward or fee.
[PBFT + PoW]
[20] Yobicash - uses PBFT and also PoW. Nodes reach consensus on transactions by querying other nodes. A node asks its peers about the state of a transaction: if it is known or not, and if it is a doublespending transaction or not. As follow : Node receives new transaction -> Checks if valid -> queries all known nodes for missing transactions (check if already in DAG ) -> queries 2/3 nodes for doublepsending and possibility -> if everything is ok add to DAG. Reward - nodes receive transaction fees + minting coins.
[Proof of Space/Proof of Capacity]
[21] Filecoin (Power Fault Tolerance) - the probability that the network elects a miner(Leader) to create a new block (it is referred to as the voting power of the miner) is proportional to storage currently in use in relation to the rest of the network. Each node has Power - storage in use verified with Proof of Spacetime by nodes. Leaders extend the chain by creating a block and propagating it to the network. There can be an empty block (when no leader). A block is committed if the majority of the participants add their weight on the chain where the block belongs to, by extending the chain or by signing blocks. Block creator rewarded with Block reward + transaction fees.
[Proof of Elapsed Time]
[22] Hyperledger Sawtooth - Goal - to solve BFT Validating Nodes limitation. Works only with intel’s SGX. PoET uses a random leader election model or a lottery based election model based on SGX, where the protocol randomly selects the next leader to finalize the block. Every validator requests a wait time from an enclave (a trusted function). -> The validator with the shortest wait time for a particular transaction block is elected the leader. -> The BlockPublisher is responsible for creating candidate blocks to extend the current chain. He takes direction from the consensus algorithm for when to create a block and when to publish a block. He creates, Finalizes, Signs Block and broadcast it -> Block Validators check block -> Block is created on top of blockchain.
[Other]
[23] Byteball (Delegated Byzantine Fault Tolerance) - only verified nodes are allowed to be Validation nodes (list of requirements https://github.com/byteball/byteball-witness). Users choose in transaction set of 12 Validating nodes. Validating nodes(Witnesses) receive transaction fees.
[24] Nano - uses DAG, PoW (HashCash). Nano uses a block-lattice structure. Each account has its own blockchain (account-chain) equivalent to the account’s transaction/balance history. To add transaction user should make some HashCash PoW -> When user creates transaction Send Block appears on his blockchain and Receive block appears on Recipients blockchain. -> Peers in View receive Block -> Peers verify block (Double spending and check if already in the ledger) -> Peers achieve consensus and add block. In case of Fork (when 2 or more signed blocks reference the same previous block): Nano network resolves forks via a balance-weighted voting system where representative nodes vote for the block they observe, as >50% of weighted votes received, consensus achieved and block is retained in the Node’s ledger (block that lose the vote is discarded).
[25] Holochain - uses distributed hash table (DHT). Instead of trying to manage global consensus for every change to a huge blockchain ledger, every participant has their own signed hash chain. In case of multi-party transaction, it is signed to each party's chain. Each party signs the exact same transaction with links to each of their previous chain entries. After data is signed to local chains, it is shared to a DHT where every neighbor node validate it. Any consensus algorithms can be built on top of Holochain.
[26] Komodo ('Delegated' Delayed Proof of Work (dPoW)) - end-to-end blockchain solutions. DPoW consensus mechanism does not recognize The Longest Chain Rule to resolve a conflict in the network, instead the dPoW looks to backups it inserted previously into the chosen PoW blockchain.

The TAU Coin Concept Which is Based on Proof of Transaction as a New Consensus Algorithm

Recently, perhaps crypto currency watchers often hear about the ideas of Proof of Work and Proof of Stake, as well as the definition of mining, or the process of how new digital currencies are released through networks.
Proof of Work
As considered the first consensus algorithm, Proof of Work (PoW) is defined as a protocol that has the main purpose of preventing cyber attacks such as distributed denial-of-service (DDoS) attacks, which aim to use up computer system resources by sending fake requests.
The concept of Proof of work already existed even before bitcoin, but Satoshi Nakamoto applied this technique to - we still don't know who Nakamoto really is - his digital currency that revolutionized traditional transaction methods.
In fact, the idea of ​​the PoW was originally published by Cynthia Dwork and Moni Naor in 1993, but the term "Proof-of-Work" was created by Markus Jakobsson and Ari Juels in a document published in 1999.
However, taking into account the date it was made, POW is probably the biggest idea behind Nakamoto's Bitcoin white paper - published in 2008 - because it allows consensus without trust and distribution.
Proof-of-Work which is performed through mining and used by Bitcoin, Litecoin and Dogecoin among others. The miner is incentivized because it receives a reward for solving the puzzle that verifies the transaction. The quantity and quality of the computer determine the mining power and consequently the profit you can make. PoW reaches consensus because the miner has to (literally) prove the verification through computational labor, and at least 51% of the miner-network has to agree with the verification.
Proof of Stake
Proof of Stake (PoS) as the second consensus algorithm, is another way to validate transactions based on distributed consensus, and to achieve distributed consensus. This is still an algorithm, and the goal is the same as proof-of-work, but the process for achieving goals is very different.
The idea of ​​proof-of-work was first proposed at the BitCointalk forum in 2011, but the first digital currency to use this method was Peercoin in 2012, along with ShadowCash, Nxt, BlackCoin, NuShares / NuBits, Qora, and Nav Coin.
Unlike proof-of-work, where the algorithm rewards miners who solve mathematical equations with the aim of validating transactions and creating new blocks, with proof-of-stake, the creator of the new block is chosen in a deterministic way, depending on wealth, or defined as well as a bet. There are no block rewards.
This PoS selects a validator (comparable to a miner) based on the number of coins it deposits. Since one validator verifies the transaction, the miner doesn’t need to waste as much energy and hardware as Proof-of-Work – where each miner tries to solve the same transaction.
In addition, all digital currencies were made beforehand and the numbers never changed. This means, in the PoS system, there are no block rewards. So, the miners take transaction fees.
However, the rich get richer as they have higher chances at the selection procedure, meaning higher chances to receive the reward. This is why, in fact, in this PoS system, miners are referred to as counterfeiters. PoS is implemented by Peercoin, Decred, and Ethereum. This verification scheme reaches consensus because the validator-network checks the reviews as well. The validator won’t verify fraudulent transactions because it will lose more money (the deposit) than it can earn (the reward).
TAU Coin Concept on Proof of Transaction
Cited from http://networkcultures.org/longform/2018/08/25/proof-of-transaction-the-materiality-of-cryptocurrency/ ,
Proof-of-Transaction is defined as "a physical object that absorbs the process of transferring value from one space or entity to another. It captures the orders of magnitude of the exchange (from technology to phenomena) and narrates these realities through interobjective relations". Further, it is explained that transaction contains a meaning of ‘an agreement’ which involves an exchange or interaction between two entities. While other word that is ‘proof’ shall be referred to ‘evidence’, the witness of an event.
The proposal of TAU is an original consensus mechanism POT. It uses on-chain historical accumulated transactions to determine who can propose a new block. Block generation in TAU is still called mining like Bitcoin, but block reward only comes in the form of transaction fee. TAU is a single utility chain that funds wiring is the only thing supported; therefore, transaction fee is the only income for miners. TAU block structure is designed to support mobile phone mining for decentralization. Total 10 billions coins are generated in the genesis block, while the goal is for each individual to have a full TAU. For every address, the probability of generating a new block is exactly in linear proportion to its historical transaction. This sum is called mining power, an analogue to hash power in Bitcoin.

Cryptocurrency Mining History : Journey to PoC

Cryptocurrency just like any other technological development has given birth to many side industries and trends like ICO, white paper writing, and mining etc… just the cryptocurrency itself rises, falls and changes to adapt real life conditions, so does its side industries and trends. Today we are going to be focusing on mining. How it has risen, fell and adapted through the journey of cryptocurrency till date.
Without going into details crypto mining is the process by which new blocks are validated and added to the blockchain. It first took to main stream in January 2009 when the mysterious Satoshi Nakamoto launched the bitcoin white paper within which he/she/they proposed the first mining consensus mechanism called proof of work (Pow).
The PoW consensus mechanism required that one should spend a certain amount of computational power to solve a cryptographic problem (nounce) in other to have the have the right to pack/verify the next block on the blockchain. In this mechanism, the more computational power one possesses the more rights they have over the packing of the next block. The quest for faster hardware has seen significant changes in the types of hard ware dominating the PoW mining community.
Back in 2009 when bitcoin first started a normal pc and its processing power worked just fine. In fact a pc with an i7 Intel processor could mine up to 50btc per day but back then it almost nothing since btc was only some few cents. When the difficulty of the network became significantly high, simple computer processing units could not match the competitiveness and so miners settled for something more powerful, the high end graphic processors (GPU). This is when the era of rigs began It was in 2010. People would combine GPUs together in mining rigs on a mother board usually in order of 6 per rig some miners operated farms containing many of these rigs. Of course with greater power came greater network difficulty and so the search for faster hard ware let to implementation of Field Programmable Gate Arrays (FPGA) in June 2012. A further search for faster, less consuming and cheaper hard ware let us to where we are today. In the year 2013, Application Specific Integrated Circuits (ASIC) miners were introduced. One ASIC miner processes 1500H/s which is 100 times processing power of CPU and GPU. But all this speed and efficiency achievements brought about another problem one which touches the core of cryptocurrency itself. The idea of decentralization was gradually fading away as wealthy and big companies are the once who could afford and build the miners therefore centralizing mining around the rich, there was a called for ASIC resistant consensus mechanism.
A movement for ASIC resistant PoW algorithms began the idea is to make ASIC mining impossible or at least make it such that using ASIC doesn’t give a miner any additional advantage as to using CPU . In 2013 the MONERO the famous privacy coin proposed CryptoNight an ASIC resistant PoW consensus at least that is how they intended it to be. But things have proven much more difficult in practice than they had anticipated as ASIC producers keep matching up to every barrier put in place the PoW designers at a rate faster than it takes to build these barriers. MONERO for example has to fork every now and then in other to keep the CryptoNight ASIC resistant a trick which is still not working as reported by their CEO “We [also] saw that this was very unsustainable. … It takes a lot to keep [hard forking] again and again for one. For two, it may decentralize mining but it centralizes in another area. It centralizes on the developers because now there’s a lot of trust in developers to keep hard forking.” Another PoW ASIC resistance algorithm is the RamdonX and there are many others but could quickly imagine that the barriers to ASIC mining in these ASIC resistance algorithm would eventually be broken by the ASIC miners and so a total shift from PoW mining to other consensus mechanisms which are ASIC resistance from core were proposed some of which are in use today.
Entered the Proof of Stake (PoS) consensus mechanism. PoS was first introduced in 2013 by the PeerCoin team. Here, a validator’s right to mine is proportionate to his/heit economic value in the network simple put the more amounts of coins you have the more mining rights you get. Apart from PeerCoin, NEO and LISK also use POS and soon to follow is EThereum. There are different variations to PoS including but not limited to delegated proof of stake DPoS, masternode proof of stake MPoS each of which seek to improve on something in the POS. This is a very good ASIC resistance consensus mechanism but it still doesn’t solves the centralization problem as the rich always have the power to more coins and have more mining rights plus it is also expensive to start. And then we have gotten many other proposals to combat this among which are Proof of Weight (PoW) and Proof of Capacity (PoC). We take more interest in PoC it is the latest and gives the best solution to all our mining challenges consensus as of now.
Proof of Capacity was first was described 2013 in the Proofs of Space paper by Dziembowski, Faust, Kolmogorov and Pietrzak and it is now being used in Burst. The main factor that separates all the mining mechanisms is the resource used. These resources which miners spend in other to have mining rights is a measure of ensuring that one has expense a none-trivial amount of effort in making a statement. The resource being spent in PoC is disk space. This is less expensive since many people already have some unused space lying around and space is a cheap resource in the field of tech. it has no discrimination over topography… it really solves lots of centralized problems present in all most other consensus. If the future is now then one could say the future of crypto mining is PoC.

Bitcoin, dogecoin. How I tried to make my fortune in 2014 with the sweat of my computer.

Bitcoin, dogecoin. How I tried to make my fortune in 2014 with the sweat of my computer.

https://preview.redd.it/mv21lvsa3do31.jpg?width=1280&format=pjpg&auto=webp&s=51bf5296a06eedc178079cf0b3ab4c3cfc44f271
Make money just by working on your computer: the rise of electronic currencies, in the wake of bitcoin, can be a little dream, especially in times of crisis. We tried the experiment. Wealth at your fingertips? Not for everybody.
Reading time: 6 min.
We have known at least since March 2013, with the soaring Bitcoin (BTC) price during the closing of Cypriot banks: electronic currencies, it has not much virtual. Since the creation of the enigmatic Satoshi Nakamoto serves as a safe haven, a playground for speculators, interests the States and even makes it possible to pay for his trip to the space where his beer, bigger world would dare to pretend that it only serves to buy prohibited substances on SilkRoad - if it ever was.
At the end of November, James Howells was mocked a lot, this Brit, caught in a household frenzy, inadvertently threw a hard disk containing 7,500 bitcoins, the equivalent of 4.8 million euros. A small fortune now lost in the depths of the Docksway dump near Newport. Nevertheless, before causing the consternation of the global Internet, Jamie still had the nose to undermine the BTC at a time when the experience mobilized a handful of hardcore geeks.
Since the rise (sawtooth) bitcoin, each unit currently weighs more than 800 dollars, nearly thirty cryptocurrencies have emerged. Is it possible, this year again, to let this promising, volatile and risky train pass, or to fall into
  1. Choose your electronic motto.
  2. All are based on the same principle: to summarize (very) big features [1], the issuance of money is governed by an algorithm, and the new corners put in circulation reward the resolution, by participants in a network of peer and mathematical problems, including the validation and archiving of transactions, which are public [2]. Mining a cryptocurrency is like putting the computing power of your computer in the service of the network.
  3. Since the program is decreasing [3], the mining becomes more and more difficult with time (and with the increase of the number of participants): to hope to make his pelote via the only computational activity, one must either have to at its disposal a large fleet of machines, to be a miner from the first hour. Exit the bitcoin, long since out of the reach of a personal computer.
  4. I similarly gave up the litecoin and peercoin, already well launched (they date respectively 2011 and 2012), to set my heart on one of the most recent currencies - and certainly the hippest of the moment: the dogecoin.
  5. As its name suggests, the cryptocurrency favorite Shiba Inus from around the world is a tribute to the Doge, one of the most famous memes of 2013, with its captions in Comic Sans, the font most sorry for the web. A geek joke, therefore, except that - the unfathomable mysteries of the Internet - its value jumped 900% in the third week of December, and she suffered a Christmas robbery online.
  6. Admittedly, at the time when these lines are written, the dogecoin caps at 0.00023 dollars [4] - its quite ridiculous (and quite depressing), but even if you bet on the future, so much to go frankly.
  7. 2. The hands in the engine the billboard.
  8. From there, things get tough (a little). Installing an electronic purse on ones computer is not very complicated (the software is available for Windows, MacOS, Android or, for the more adventurous, on a repository to compile under Linux). It is also possible to use an online wallet, but it is more risky (except, perhaps, when one is called James Howells). When opened for the first time, the purse automatically synchronizes with the Dogecoin network (be careful, it can be long), which gives you a payment address (we can generate more later).
  9. The two most common ways to undermine electronic money are to use the computing power of the computers microprocessor (CPU) or, more efficiently, that of the graphics card processor (GPU). In the first case, the program is simple to install; in the second, it is necessary to choose the most adapted to its material [5]. There are, thankfully, a lot of online tutorials. Still, to operate the corner board requires in all cases to trade the comfort of the GUI for aridity, so confusing to the layman, command lines - we have nothing for nothing.
  10. Finally, at work alone, we prefer collaboration. Mining is best done in groups, or rather in pool: it distributes the gains, of course, but also the difficulty. For the dogecoin as for all the crypto-currencies, the pools are numerous. A quick tour of a dedicated section of the Reddit community site can help you make your choice.
  11. 3. Extension of the field of struggle.
  12. And after? After, we can rest, since it is the machine that works. But the truth of a cryptocurrency - even at the exceptionally high LOL and LOL rates of the Shiba Inu - is cruel and brutal: not all computers are equal. Or rather, some are more equal than others. For while you heat your CPU or your graphics card to grapple some unfortunate corners, others will sweep the game thanks to specialized integrated circuits, computing capabilities much higher.
  13. If the game of buying and reselling corners is basically just another stock exchange mechanism, less the intervention of the central banks - what is at stake, and the big political question they ask: are we certain to prefer speculation pure and perfect to monetary policies, however questionable they may be? -, production, it is the law of the strongest (in calculation). There are even lethal weapons at $ 10,000 each, with which your processors are like mosquitoes in front of an A bomb.
  14. And if you think it does not matter because after all, it does not cost you anything, think again: the components, like humans, wear out faster when they work at full speed, and the bill of electricity can quickly grow. The profitability of the case is anything but certain, as evidenced by the results of online calculators. (Needless to say, our laughing dogecoin does not stand up to this kind of simulation.)
  15. Much more boring, from a collective point of view: the carbon footprint, current and above all expected, of electronic currencies worries more and more. Last spring, Bloomberg estimated that the energy consumption of the Bitcoin network was equivalent to that of 31,000 US households. Not sure, according to the site, that their emission is less damaging to the environment than have been some physical currencies.
  16. For exciting to analyze that is the emergence of cryptocurrencies, it is better to ask now about their cost, economic and ecological. To see it as a potential source of income, except for being a very early adopter with a hollow nose, an individual with a lot of computational capital or a clever trader, you have to make a point.
  17. If the recurrent comparison with the famous Ponzi pyramid [6] is discussed (after all, the decentralized currencies do not make promises), remains that, as long as the value does not collapse, the system benefits mainly to the first entrants - except James Howells.
  18. As the Bitcoin.fr site aptly states: all this is just an experiment, invest only the time and money you can afford to lose. LOLs love was not a worse reason than another to experiment, so I finally submitted my laptop to four days and three nights of intense activity, which makes me happy. owner of a good half a thousand dogecoins. Either the equivalent of 0.115 dollar, or 0.08 euro. It is obviously not worth the electricity consumed to generate them, it increases my carbon footprint, but it amuses my entourage. But laughter is, as everyone knows, a safe bet in times of crisis, less volatile than a real bitcoin.
  19. And then, after all, you never know.
  20. Amaelle Guiton.
  21. 1. For explanations more provided (the case is quite complex), refer, for example, to the series of very detailed notes devoted to blogger Turblog.
  22. 2. And as such, searchable by everyone. It is the identity of the users that is not known, unless they reveal it, hence the reputation of anonymity (relative, therefore) cryptocurrencies.
  23. 3. In the case of bitcoin, the maximum of 21 million units should be reached around 2140.
  24. 4. For a day-to-day follow-up, see the CoinMarketCap site which lists the exchange rates of crypto-currencies, based on the dollar value of bitcoin.
  25. 5. We discover then, unfortunately, that some graphics cards do not allow the mining. This is the case for the author of these lines, reduced to working in conditions of extreme computer deprivation.
  26. 6. Comparison which is at the heart of a hilarious note on the ponzicoin, signed by the economic journalist Matthew OBrien, on The Atlantic (to read if you intend seriously to invest in the dogecoin).

Crypto Mining for Beginners. Is it really worth it?

Crypto Mining for Beginners. Is it really worth it?

Image from blokt.com
Mining cryptocoins is an arms race that rewards early adopters. You might have heard of Bitcoin, the first decentralized cryptocurrency that was released in early 2009. Similar digital currencies have crept into the worldwide market since then, including a spin-off from Bitcoin called Bitcoin Cash. You can get in on the cryptocurrency rush if you take the time to learn the basics properly.

Which Alt-Coins Should Be Mined?


Image from btcwarp.com
If you had started mining Bitcoins back in 2009, you could have earned thousands of dollars by now. At the same time, there are plenty of ways you could have lost money, too. Bitcoins are not a good choice for beginning miners who work on a small scale. The current up-front investment and maintenance costs, not to mention the sheer mathematical difficulty of the process, just doesn't make it profitable for consumer-level hardware. Now, Bitcoin mining is reserved for large-scale operations only.
Litecoins, Dogecoins, and Feathercoins, on the other hand, are three Scrypt-based cryptocurrencies that are the best cost-benefit for beginners.
Dogecoins and Feathercoins would yield slightly less profit with the same mining hardware but are becoming more popular daily. Peercoins, too, can also be a reasonably decent return on your investment of time and energy.
As more people join the cryptocoin rush, your choice could get more difficult to mine because more expensive hardware will be required to discover coins. You will be forced to either invest heavily if you want to stay mining that coin, or you will want to take your earnings and switch to an easier cryptocoin. Understanding the top 3 bitcoin mining methods is probably where you need to begin; this article focuses on mining "scrypt" coins.
Also, be sure you are in a country where bitcoins and bitcoin mining is legal.

Is It Worth It to Mine Cryptocoins?

As a hobby venture, yes, cryptocoin mining can generate a small income of perhaps a dollar or two per day. In particular, the digital currencies mentioned above are very accessible for regular people to mine, and a person can recoup $1000 in hardware costs in about 18-24 months.
As a second income, no, cryptocoin mining is not a reliable way to make substantial money for most people. The profit from mining cryptocoins only becomes significant when someone is willing to invest $3000-$5000 in up-front hardware costs, at which time you could potentially earn $50 per day or more.

Set Reosonable Expectations

If your objective is to earn substantial money as a second income, then you are better off purchasing cryptocoins with cash instead of mining them, and then tucking them away in the hopes that they will jump in value like gold or silver bullion. If your objective is to make a few digital bucks and spend them somehow, then you just might have a slow way to do that with mining.
Smart miners need to keep electricity costs to under $0.11 per kilowatt-hour; mining with 4 GPU video cards can net you around $8.00 to $10.00 per day (depending upon the cryptocurrency you choose), or around $250-$300 per month.
The two catches are:
1) The up-front investment in purchasing 4 ASIC processors or 4 AMD Radeon graphic processing units
2) The market value of cryptocoins
Now, there is a small chance that your chosen digital currency will jump in value alongside Bitcoin at some point. Then, possibly, you could find yourself sitting on thousands of dollars in cryptocoins. The emphasis here is on "small chance," with small meaning "slightly better than winning the lottery."
If you do decide to try cryptocoin mining, definitely do so as a hobby with a very small income return. Think of it as "gathering gold dust" instead of collecting actual gold nuggets. And always, always, do your research to avoid a scam currency.

How Cryptocoin Mining Works

Let's focus on mining scrypt coins, namely Litecoins, Dogecoins, or Feathercoins. The whole focus of mining is to accomplish three things:
- Provide bookkeeping services to the coin network. Mining is essentially 24/7 computer accounting called "verifying transactions."
- Get paid a small reward for your accounting services by receiving fractions of coins every couple of days.
- Keep your personal costs down, including electricity and hardware.

The Laundry List: What You Will Need to Mine Cryptocoins


https://preview.redd.it/gx65tcz0ncg31.jpg?width=1280&format=pjpg&auto=webp&s=f99b79d0ff96fe7d529dc20d52964b46306fb070
You will need ten things to mine Litecoins, Dogecoins, and/or Feathercoins.
1) A free private database called a coin wallet. This is a password-protected container that stores your earnings and keeps a network-wide ledger of transactions.
2) A free mining software package, like this one from AMD, typically made up of cgminer and stratum.
3) A membership in an online mining pool, which is a community of miners who combine their computers to increase profitability and income stability.
4) Membership at an online currency exchange, where you can exchange your virtual coins for conventional cash, and vice versa.
5) A reliable full-time internet connection, ideally 2 megabits per second or faster speed.
6) A hardware setup location in your basement or other cool and air-conditioned space.
7) A desktop or custom-built computer designed for mining. Yes, you may use your current computer to start, but you won't be able to use the computer while the miner is running. A separate dedicated computer is ideal. Do not use a laptop, gaming console or handheld device to mine. These devices just are not effective enough to generate income.
8) An ATI graphics processing unit (GPU) or a specialized processing device called a mining ASIC chip. The cost will be anywhere from $90 used to $3000 new for each GPU or ASIC chip. The GPU or ASIC will be the workhorse of providing the accounting services and mining work.
10) A house fan to blow cool air across your mining computer. Mining generates substantial heat, and cooling the hardware is critical for your success.
11) You absolutely need a strong appetite of personal curiosity for reading and constant learning, as there are ongoing technology changes and new techniques for optimizing coin mining results. The most successful coin miners spend hours every week studying the best ways to adjust and improve their coin mining performance.
