Beginner's Guide To Ethereum Casper Hardfork: What You Need To Know

Beginner's Guide To Ethereum Casper Hardfork: What You Need To Know

The Casper updates mission is straightforward, then: to shift ether from being a PoW coin to a Proof-of-Stake (PoS) coin . As opposed to the PoW consensus protocol, the PoS protocol achieves consensus through stakerssometimes referred to as minters, toowho stake their coins by locking them down in specialized wallets . With these stakers at work, mining will become redundant, meaning the Ethereum network post-Casper will rely on stakers and staking pools instead of miners for its operability. And, like miners, stakers will be rewarded for their service to the network. Minters will receive an annual dividend of ether (collected from network fees), so staking would be a lucrative endeavor for those with enough coins. Naturally, then, the more ETH you stake, the larger your annual dividends will be. For now, Ethereums developers havent arrived at a hard number for the amount of ETH that will be required to stake. What they have confirmed, though, is that the number will likely start out higher before gradually being brought considerably lower. For instance, Ethereum founder Vitalik Buterin has recently thrown around a guesstimate of needing approximately 1,000 ETH to be one of the networks inaugural stakers. He said that number could be dropped down to as low as 10 ETH over time. Whatever the number ends up being, users will still be able to band together and create staking pools, just like there are robust mining pools in the Bitcoin and Ethereum communities today. Youll simply pitch your desired amount of ether in, lock in down with your peers, and rake in the dividends together (to be shared proportionally, of course). Well, the Casper update is certainly a team effort, but its inarguable that top Ethereum researcher Vlad Zamfir has been at the vanguard of the updates Continue reading >>

Ethereums Switch To Proof Of Stake Better Than Proof Of Work?

Ethereums Switch To Proof Of Stake Better Than Proof Of Work?

By UseTheBitcoin in Cryptocurrency News Guides Home If youre at least interested in the cryptocurrency space, youve probably heard of Ethereum. Its currently the second largest coin by market cap, primarily because so many other tokens run on Ethereum, and partly because the development team is very talented. Either way, this post is about the switch from POW to POS. Well, POW is currently used by most cryptocurrencies including Bitcoin, Ethereum (for now) and Litecoin. If a coin is minable, that means its utilizing a POW system. Miners use their GPUs or ASICs to solve cryptographic hash functions which verify the blockchain. GPUs primarily designed for gaming like the RX 580 are now being employed by miners. Their GPUs are rapidly guessing and checking different solutions to a next to impossible math problem. When they successfully solve the equation, the ledger (blockchain) is updated and the miner receives a block reward in the form of a token and/or transaction fees. This is called Proof-of-Work because miners are doing lots of work in the form of processing mathematical equations with their mining hardware. Without miners, many networks wouldnt exist. Miners pay for electricity in exchange for tokens. What is Proof of Stake and How its different Proof-of-Stake is a bit different. Previously miners proved how fast they could verify the network; now, ETH holders will show how much they own by running something called a master node . When you create a master node, you have to lock up a certain amount of ETH to prove you own it. Rewards are distributed based on how much you have locked away and how long its locked away for. Instead of 1,000 miners verifying the network for example, there might be around 10,000 wallets holding Ethereum through Proof-of-Stake. With POS, Continue reading >>

While Ethereum Figures Out How To Implement Pos, This Blockchain Startup Is Already Steaming Ahead

While Ethereum Figures Out How To Implement Pos, This Blockchain Startup Is Already Steaming Ahead

While Ethereum Figures Out How to Implement PoS, This Blockchain Startup is Already Steaming Ahead There has been a lot of attention drawn towards the Proof-of-Stake mechanism recently, especially ever since Ethereum announced that it would be moving away from its current Proof-of-Work (PoW) system . For those new to blockchain technology, the differences between these two mechanisms can seem difficult and confusing. For more information, there are many in-depth articles available elaborating on the differences between the Proof-of-Work mechanism and the Proof-of-Stake mechanism . However, while the specifics of each mechanism are quite complicated, it is easy to understand what sets the two methods apart. What Are the Major Differences Between Proof-of-Stake (PoS) and Proof-of-Work (PoW)? The main difference between PoS and PoW is that PoS has no resource-heavy mining involved. With PoW, miners are responsible for computing complex algorithms in order to secure consensus. With PoS, coins are minted or forged. This makes PoS much more cost-effective than PoW. PoS is also much less reliant on mining factories than PoW. Therefore, a PoS approach could be much more resistant to censorship in light of Chinas recent ban of crypto exchanges , as it is likely that mining operations could be a lucrative centralized target to censor in the future. Ethereums Transition From Proof-of-Work (PoW) to Proof-of-Stake (PoS) Ethereums future Casper update is set to transform Ethereum from the PoW mechanism to the PoS mechanism. This PoS protocol will achieve consensus through stakers who essentially stake their coins by locking them down in specialized wallets. Similar to the way miners are currently rewarded, stakers will be rewarded in return for their service to the network. They wil Continue reading >>

It Is No Longer Worth It To Build An Ethereum Mining Rig

It Is No Longer Worth It To Build An Ethereum Mining Rig

It Is No Longer Worth It To Build An Ethereum Mining Rig Building an Ethereum mining rig hasnt been worth it for months, and soon they will be completely obsolete. Goodnight, sweet prince. Image: Daniel Oberhaus/Motherboard Back in May I wrote a guide explaining how to build an Ethereum mining rig , a special type of computer that forms the backbone of the Ethereum network and earns ether, the digital currency native to the network, for its owner. Shortly thereafter, Motherboard also made a video documenting this process . Since then, Ive received countless emails from readers inquiring about my mining rig. Ive received three such emails this week. The most common question voiced by these readers is whether or not it is still worth it to build a mining rig. The answer to this question is no. Building an Ethereum mining rig hasnt been worth it for months and a few months from now, mining ether will be completely obsolete. Read More: An Idiot's Guide to Building an Ethereum Mining Rig Arguably, building an Ethereum mining rig wasnt even worth it when I built my machine in May, and many readers let me know this when the article and video first came out. This is somewhat true, but there is a necessary caveat here. Mining ether also wasnt worth it for about the first year and a half of the cryptocurrencys existence. The price of ether hovered around $10 from 2015 until early 2017, when it saw a spike to $25. This was important because it meant the value of the ether being mined was higher than the cost of the electricity that was needed to mine it. In other words, until that point small scale mines were operating at a loss in the belief that the tokens they were mining would someday be worth a lot more money. In hindsight, these early miners were rightthe price of ether has Continue reading >>

Ethereum Proof Of Stake Explained

Ethereum Proof Of Stake Explained

So you might have heard that Ethereum is considering changing its distributed consensus system tosomething called proof of stake. Here, we will try to explain what this is as well as how it may affect you. To truly understand proof-of-stake (PoS) it is easier if we also explain the current system being used by Ethereum, and that is proof of work ( Ethereum Mining ). So basically when Ethereum is transferred, miners group that up into a ledger called a block chain and to do this they have to solve a puzzle. In creating this blockchain, a lot of computational power is also used. The amount of reward you get for creating a blockchain is a transaction reward. However, this depends on how much work you ie. how fast you can calculate and solve the puzzle. So this is all going to go away once proof of stake comes along. With proof of stake, you dont actually solve any puzzles. You remove the puzzle solving element from the system and thus change the way the reward is distributed. So instead of proving how fast you can calculate with hashrate, you need to prove how much Ethereum you own. You do this with something called a master node. When you create a master node, you have to lock up a certain amount of Ethereum to prove that you have it and rewards are distributed according to how much proof of stake you have. One can create multiple master nodes with a lot of Ethereum inside and youll earn more through this method. So thats going to be extremely interesting for everyone. Weve seen proof of stake currencies before. Dash is one example where 50% of the rewards is done by mining and the other 50% is done by proof of stake. And there is PIVX which is 100% proof of stake. The advantage ofproof of stake is huge. One benefit is that you no longer have to do the calculations which Continue reading >>

When Will Ethereum Mining End?

When Will Ethereum Mining End?

In August of this year (2017), Vitalik Buterin, creator of Ethereum , released the implementation guide for the first version of Casper. As a hybrid proof-of-stake (PoS)/proof-of-work (PoW) algorithm, Casper v1 is going to decrease (and eventually end) the profitability for Ethereum miners . The release date is estimated to be sometime in 2018 as part of the Constantinople hard fork and theres a lot to learn before this happens: Casper is a PoS algorithm thats projected to be released on the Ethereum network sometime in 2018. Beginning as a hybrid with the current PoW algorithm, the first version of Casper will only use a PoS consensus to validate every 100th block, called checkpoints. Once a checkpoint is validated, theres no way to go back and use a chain without it. Even if 99% of miners support a chain that doesnt include a checkpoint block, all clients in the network will still continue to use the one with the checkpoints. This removes a lot of the power that miners currently have. The Ethereum community hypothesizes that the switch to PoS will help with the scaling issues that the network is currently facing. The algorithm should enable new blocks to be created more quickly while allowing the network to scale more efficiently through sharding. Sharding is a horizontal partitioning of a large database into smaller and more easily managed parts. Beyond that, PoS algorithms also use less energy to run the network, reduce centralization, and make 51% attacks more difficult. With the upcoming hard fork, there could potentially be three forks of Ethereum: And, if youre a miner, you may be thinking, No big deal, Ill just continue to mine and give support to the Ethereum PoW fork. The Ethereum developers have stated that theyll be releasing what they call the difficulty Continue reading >>

Proof Of Work Vs Proof Of Stake: Basic Mining Guide

Proof Of Work Vs Proof Of Stake: Basic Mining Guide

Proof of Work vs Proof of Stake: Basic Mining Guide Angel Investors, Startups & Blockchain developers... Recently you might have heard about the idea to move from an Ethereum consensus based on the Proof of Work (PoW) system to one based on the so-called Proof of Stake. In this article, I will explain to you the main differences between Proof of Work vs Proof of Stake and I will provide you a definition of mining, or the process new digital currencies are released through the network. Also, what will change regarding mining techniques if the Ethereum community decides to do the transition from work to stake? This article wants to be a basic guide to understanding the problem above. First of all, lets start with basic definitions. Proof of work is a protocol that has the main goal of deterring cyber-attacks such as a distributed denial-of-service attack (DDoS) which has the purpose of exhausting the resources of a computer system by sending multiple fake requests. The Proof of work concept existed even before bitcoin , but Satoshi Nakamoto applied this technique to his/her we still dont know who Nakamoto really is digital currency revolutionizing the way traditional transactions are set. In fact, PoW idea was originally published by Cynthia Dwork and Moni Naor back in 1993, but the term proof of work was coined by Markus Jakobsson and Ari Juels in a document published in 1999. But, returning to date, Proof of work is maybe the biggest idea behind the Nakamotos Bitcoin white paper published back in 2008 because it allows trustless and distributed consensus. Whats trustless and distributed consensus? A trustless and distributed consensus system means that if you want to send and/or receive money from someone you dont need to trust in third-party services. When you use tra Continue reading >>

Proof Of Stake Faq Ethereum/wiki Wiki Github

Proof Of Stake Faq Ethereum/wiki Wiki Github

See A Proof of Stake Design Philosophy for a more long-form argument. No need to consume large quantities of electricity in order to secure a blockchain (eg. it's estimated that both Bitcoin and Ethereum burn over $1 million worth of electricity and hardware costs per day as part of their consensus mechanism). Because of the lack of high electricity consumption, there is not as much need to issue as many new coins in order to motivate participants to keep participating in the network. It may theoretically even be possible to have negative net issuance, where a portion of transaction fees is "burned" and so the supply goes down over time. Proof of stake opens the door to a wider array of techniques that use game-theoretic mechanism design in order to better discourage centralized cartels from forming and, if they do form, from acting in ways that are harmful to the network (eg. like selfish mining in proof of work). Reduced centralization risks, as economies of scale are much less of an issue. $10 million of coins will get you exactly 10 times higher returns than $1 million of coins, without any additional disproportionate gains because at the higher level you can afford better mass-production equipment. Ability to use economic penalties to make various forms of 51% attacks vastly more expensive to carry out than proof of work - to paraphrase Vlad Zamfir, "it's as though your ASIC farm burned down if you participated in a 51% attack". How does proof of stake fit into traditional Byzantine fault tolerance research? There are several fundamental results from Byzantine fault tolerance research that apply to all consensus algorithms, including traditional consensus algorithms like PBFT but also any proof of stake algorithm and, with the appropriate mathematical modeling, pr Continue reading >>

What To Mine After Ethereums Pos: World's First Bitcoin Mining Pool Adds Zcash Support

What To Mine After Ethereums Pos: World's First Bitcoin Mining Pool Adds Zcash Support

What to Mine After Ethereums PoS: World's First Bitcoin Mining Pool Adds Zcash Support The development team behind the anonymous cryptocurrency Zcash revealed that Slush Pool, the worlds first Bitcoin mining pool, has added support for Zcash. Zooko Wilcox, the CEO of Zerocoin Electric Coin Company (ZECC), the development team behind the anonymous cryptocurrency Zcash, revealed that Slush Pool, the worlds first Bitcoin mining pool, added support for Zcash. In a public statement, Slush Pool announced : We have introduced support for Zcash mining today. That is quite a huge step for us, as we have focused solely on Bitcoin and merged mining so far. It took us many months to develop and thoroughly test our Zcash mining system. We have already successfully mined over 20 blocks during the private testing stage and we are hungry for more. In its blog post entitled 5 Reasons to Mine Zcash with Slush Pool, Slush Pool outlined five major reasons why miners should be interested in mining Zcash. One of the reasons listed by the Slush Pool team was Advanced Account Security. In October of 2016, Trezor reaffirmed the importance of Universal Second Factor (U2F) and its advantages over applications such as Googles Authenticator that is built on top of a 2FA implementation called a Time-based One-time password. While the TOTP method utilized by Google and its widely utilized application Google Authenticator is simple to implement, the Trezor development team revealed that it has severe weaknesses and inconveniences. Mostly, the disadvantages of TOTP are related to security issues that may arise due to the lack of back up and the maintenance of backup codes online. Any file, data or server that is connected to the Internet and brought online can be vulnerable to attacks and security bre Continue reading >>

What Does Proof Of Stake Mean For Ethereum?

What Does Proof Of Stake Mean For Ethereum?

What does Proof of Stake mean for Ethereum? One major issue with Ethereum mining is the high consumption of power. Processing transactions costs an ever-increasing amount of electricity which is not only bad from a financial perspective but also bad for the environment. The main concept used in cryptocurrency mining is proof of work (PoW) which means miners get rewarded when they solve puzzles to validate transactions and create new blocks. Though it works and is used by the majority of cryptocurrencies, there is a need for a lot of computing power for new transactions to be verified. According to an approximation done by Vitalik Buterin who is the founder of Ethereum, it uses electricity costing up to $1M daily in order to process daily transactions. Since mining is becoming less financially feasible over time the founder proposed switching to a different concept as an alternative to proof of work called proof of stake. As opposed to proof of work where miners have to solve complicated algorithms to validate a transaction, in proof of stake miners are those that are willing to stake part of their cryptocurrency on the blocks they think should be added to the blockchain. Proof of stake depends on validators economic stake in the network. In a PoS based blockchain, miners who are the validators have their own turn in voting and proposing the next block. The weight of the vote of the validator will depend on their stake in the network which is basically the deposit of cryptocurrency they have. The blockchain will keep a record of validators and those who hold the blockchains base cryptocurrency. If one holds the blockchains base cryptocurrency they can easily become a miner or a validator as all they need to do is to give up their ether into a locked deposit through a sp Continue reading >>

When Ethereum Implements Pos, Can The Existing Rig Be Used To Mine Ether Further? | Virtual Currencies - Quora

When Ethereum implements POS, can the existing rig be used to mine Ether further? The short answer is no, because with the transition to Proof of Stake It would be not necessary to use mining rigs anymore. The transactions validation will be based on distributed consensus. Here an interesting infographic to Compare the current Ethereum proof of work (POW) to proof of stake (POS). After POS you can use your mining rig in three ways: Mine other cryptocurrencies, however you can expect an increase in complexity and a decrease in profit, because all the others ether-miners will do the same. Hopefully rent your computational power. Take a look at the project. The concept is similar to Golem project. Play video games :-) ( you would need also good CPU) I didnt mention resell your mining rig because it will be probably not a good deal. To keep up with the latest development of cryptocurrency trading, subscribe to our telegram channel on Coin Trading for all . > important informations regarding cryptocurrencies Your income of ETH will be proportional to how much of it youre staking. Honestly, I wouldnt even bother trying to mine ETH once its POS with GPUs. Either use the rig to mine another POW coin, use the GPU to play some games. Frankly, you might find that its actually more profitable to already mine another coin besides ETH. Use this website for a good comparison: Crypto coins mining calculator. Bitcoin Ethereum Zcash X11 Blake Note that POW coins will yield you less coins in turn as it becomes more difficult to mine. This doesnt mean it wont be profitable as the velocity of the coins value might be greater than the velocity of the coins difficulty. Edit: For clarity POW means Proof of Work, and POS is Proof of Stake. Simplistically, POW nets you coins for heavy CPU/GPU w Continue reading >>

What Does Pos Mean For Ethereum Mining, And If I Build A Mining Rig, How Will It Affect Me?

What Does Pos Mean For Ethereum Mining, And If I Build A Mining Rig, How Will It Affect Me?

What does POS mean for Ethereum mining, and if I build a mining rig, how will it affect me? A2A. Proof of Stake essentially means, the probability for a node to mine a transaction (block) is directly proportional to the Stake the node (e.g. amount of Ether it previously mined) has in the network. Unlike BitCoin where every block gives a fair chance to all the nodes in the network (barring network latency), PoS requires the nodes to prove their stake in the network. Though the idea is fairly simple, the possibilities of a node hedging its bets across multiple possibilities that it always ends up gaining out of all transactions makes it challenging to adopt. There are some nice solutions that Ethereum proposes to overcome this. However, similar to PoW there is no mathematical proof for the hardness of these schemes. In a nutshell, PoS will make it less meaningful to have mining farms. Instead buy a rack in a co-lo and dedicate it to the p2p network. Which is completely in line with Ethereum philosophy of building a World Computer unlike BTC. Continue reading >>

Ethereum's Big Switch: The New Roadmap To Proof-of-stake - Coindesk

Ethereum's Big Switch: The New Roadmap To Proof-of-stake - Coindesk

Ethereum's Big Switch: The New Roadmap to Proof-of-Stake After years of development, ethereum has a new planto update the algorithm that keeps its entire network in sync. Vitalik Buterin, ethereum's creator , recently released a rough implementation guide that reveals the network's developers will first start with a 'hybrid' system that merges bitcoin-style proof-of-work mining with itsmuch-anticipated and still-experimental proof-of-stake system called Casper, created by Buterin. The planeffectively meansethereum will begin alternating between the two systems, so that some transaction blocks (one out of 100) are secured viaproof-of-stake and the rest remain on proof-of-work. Buterin has notably been working on his implementationin parallel with ethereum developer Vlad Zamfir, "cross-pollinating" their ideas. According toKarl Floersch, blockchain engineer for ethereum startup ConsenSysand a coder working with Buterin on Casper's development, the result is that the network is choosing the more conservative of two potential paths forward. "What Vitalik has come up with is a get-it-out-the-door, working version, that works, but might be less theoretically revolutionary than Vlad's." Because Buterin's implementation of Casper can, he thinks, get to production faster, it will be used in the first stage of ethereum's evolution. If implemented, this would be the first time proof-of-stake would be employed on the live ethereum platform, albeit playing a minor role. It also would a largereal-world test of proof-of-stake, enabling the cryptocurrency community to determine whether the proof algorithm is asuperior one, as proponents have argued. To advocates, the goal of this potentially revolutionary change to proof-of-stake is to reduce the electricityethereum requires to reacha Continue reading >>

Proof Of Stake (pos)

Proof Of Stake (pos)

Proof of Stake (PoS) concept states that a person can mine or validate block transactions according to how many coins he or she holds. This means that the more Bitcoin or altcoin owned by a miner, the more mining power he or she has. The first cryptocurrency to adopt the PoS method was Peercoin . Nxt, Blackcoin, and ShadowCoin soon followed suit. The proof of stake was created as an alternative to the proof of work (PoW), to tackle inherent issues in the latter. When a transaction is initiated, the transaction data is fitted into a block with a maximum capacity of 1 megabyte, and then duplicated across multiple computers or nodes on the network. The nodes are the administrative body of the blockchain and verify the legitimacy of the transactions in each block. To carry out the verification step, the nodes or miners would need to solve a computational puzzle, known as the proof of work problem. The first miner to decrypt each block transaction problem gets rewarded with coin. Once a block of transactions has been verified, it is added to the blockchain, a public transparent ledger. Mining requires a great deal of computing power to run different cryptographic calculations to unlock the computational challenges. The computing power translates into a high amount of electricity and power needed for the proof of work. In 2015, it was estimated that one Bitcoin transaction required the amount of electricity needed to power up 1.57 American households per day. To foot the electricity bill, miners would usually sell their awarded coins for fiat money , which would lead to a downward movement in the price of the cryptocurrency. The proof of stake (PoS) seeks to address this issue by attributing mining power to the proportion of coins held by a miner. This way, instead of utiliz Continue reading >>
