Part One Of Ethereum's Sharding Roadmap Is Nearly Done

Part One of Ethereum's Sharding Roadmap Is Nearly Done Jan 26, 2018 at 17:10 UTC|UpdatedJan 27, 2018 at 02:39 UTC Ethereum is getting closer to deploying new technology that would allow the network to scale, its founder said. "It seems like part one of phase one is getting something like being already done," Vitalik Buterin said in a developer meeting. The technology, known as sharding,attempts to split the ethereum blockchain's data into more manageable parts. Pointing to an initial spec posted on Github, Buterin said: "It's theoretically a good spec of what minimal sharding is going to look like." Ethereum is under pressure to keep up with the rising popularity of the platform, which has led to slower transaction times and high processing fees. The congestion has already led some token-based projects to build atop other blockchains such as Stellar . Buterin went to state that the next phase of the four-stage scaling proposal will be completed in "a month and a bit," adding that development work will likely circulate on stateless clients, a type of ethereum software that does not need to process the complete history of the platform. "Then from there we're going to try and shard it into a working test, a kind of test network," the ethereum founder said. In the meeting, Buterin also reflected on Casper, ethereum's new consensus protocol that is currently in testing. As detailed by CoinDesk , the test network has been derailed by issues with the software it deploys. However, Buterin said that in spite of hiccups, the core of the project is sound, or as he put it: "the Casper aspect of Casper... is totally successful." Still, with the code yet to be adapted for use across different ethereum software clients, he acknowledged: "That's on a bit of a back burner for now." The Continue reading >>

Vlad Zamfir On Twitter: Casper Release Date

Vlad Zamfir On Twitter: Casper Release Date "soon" - Ethtrader

Vlad Zamfir on Twitter: Casper release date "soon" I like Vlad, he wished us all a Merry Christmas :) I was only exposed to him recently when kitties took our network under siege. Someone mentioned some FUD about ethereum scaling and attributed it to him. I then found the source and Vlad was well-written, clearly passionate, and very smart. The FUD ended up just being FUD of course Oh, when he literally said that ETH isn't secure or scalable. can you point out where he said that please? (I sold all my ETH for $16) Hmm... I rather wait for them to show a little bit more than just the numbers. They have an internal testnet and public testnet out this year. Ive never seen a more competent team as Zilliqa, ask them any technical question on Slack and theyll respond thoroughly. Zilliqa sold out in presale, there was a small community round but too late for that. Everyone are waiting to buy on exchange for those ICX gains. I hate ICOs like that. The polkadot ICO was the most honest and fair ICO I've ever seen so far. It tells a lot about a project. But I check Zilliqa once their tokens are out The reason it sold out was because eth suddenly doubled over a week. They planned to have 50% 50% presale/ico contribution. They used Bitcoinsuisse. But Polkadot lost all their eth...and collected so much as well. I really dont like reverse dutch auctions which is basically an uncapped raise. Zilliqa stuck to their 20m + 2mil community and i prefer that to deciding to raise an unlimited amount. You have a point on the Cap - it's a good thing. From my understanding: Named after the cartoon "Casper the friendly ghost" is an upgrade that will help change ethereum from proof of work (PoW) to proof of stake (PoS). PoW - is what we have now lots of graphics cards mining and confirming transa Continue reading >>

Lightning Network For Ethereum? Eth Surges As Casper Approaches

Lightning Network For Ethereum? ETH Surges as Casper Approaches Lightning Network For Ethereum? ETH Surges as Casper Approaches As Bitcoin calms down after its latest roller-coaster ride, Ethereum has soared to unprecedented heights. The coin briefly peaked at just over $900 on January 2nd, and appears to be heading back up and beyond following a brief dip at the time of press. 2017 was a year of eye-popping growth for the cryptocurrency markets at large, and the rise of Ethereum was undoubtedly one of the most significant parts of the crypto journey throughout the year. According to Ethereums official blog, transactional volume on the ETH blockchain has more than doubled within the last several months. The network has reportedly processed an average of ten transactions per second for periods lasting as long as a few days. While ten tx/second may not seem to be much compared to the 24,000 tx/second capabilities of the Visa network, its more than double the average Bitcoins 4 tx/second. Ethereum also reported that the number of accounts created per day passed 100,000 as well as an increase of nodes (computers that uphold a blockchains network) despite rising system requirements. While much of Ethereums rise throughout the year can be contributed to the blossoming era of ICOs and several regulatory measures that legitimized Ethereum as legal tender in several countries throughout the world, the most recent rise could be attributed to the approaching Casper software update that will improve security and scalability on the Ethereum network. Although Bitcoins scalability issues have received quite a bit more publicity than Ethereums, implementing a scalability solution for the Ethereum network has become an increasingly urgent task as the network supports a growing number o 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 >>

Update On The Ethereums Casper Pos Hybrid And Sharding

Update On The Ethereums Casper Pos Hybrid And Sharding

All seems to be going well for development at the worlds second most valuable cryptocurrency. The team at the Ethereum foundation is actively busy testing the latest featured of the Metropolis upgrade . One of the most important of these features was the movement from Proof-of-Work mining to Proof-of-Stake. Ethereum has been working on a hybrid between the two solutions that has aptly been named the Casper POS protocol . This has been on the Testnet and has been running for a few weeks already. According to Vitalik Buterin who is the founder of Ethereum: The Casper aspect of Casper, where two conflicting blocks should not be able to be finalized, seems to actually happen running and the network agrees all along what the final chain is Although the Casper Hybrid has been running in the testing environment, it has not been without a few problems. Apparently the nodes losing their connection and get floods of new connections so the developers have had to institute clever hacks to get around this. This means that the Ethereum developers will have to complete quite a bit more testing before there can be any sort of live implementation of the protocol. However, according to Buterin it seems as if the most important part of the upgrade is indeed effective. This is the manner in which conflicting nodes are able to reach a network consensus. With the minor reconnection issues corrected, it is entirely possible that we could see Casper hitting the Mainnet by the middle of the year. There has also been quite a lot of work that has been done on the sharding side. This is arguably one of the most important updates to blockchain technology ever as it aims to markedly decrease transaction times. Blockchain sharding uses parallelisation of blockchains. This will eliminate the ineffici Continue reading >>

Ethereum Launches Casper Testnet, Paving The Way For Proof-of-stake

Ethereum Launches Casper Testnet, Paving The Way For Proof-of-stake

Ethereum Launches Casper Testnet, Paving the Way for Proof-of-Stake Ethereum developers have launched an alpha test network (testnet) for Casper, paving the way for the cryptocurrency to eventually transition to a proof-of-stake (PoS) consensus algorithm. Like bitcoin, ethereum currently operates on a proof-of-work (PoW) consensus algorithm, meaning that the network is secured and new currency units are issued through mining, whereby participants solve cryptographic puzzles to validate transactions and create new blocks. However, PoW has attracted criticism over the years, both for its tendency to centralize mining hardware into a few pools and for the amount of electricity it consumes. Ethereum aims to address these problems by transitioning to Casper , a proof-of-stake (PoS) consensus algorithm. Under Casper, participants can become validators by locking up or staking ether. Validators will take turns proposing and voting on blocks, and both the weight of their votes and the size of their rewards will hinge on the size of their stakes. According to developers, moving to Casper will greatly reduce the amount of electricity wasted through PoW mining. In addition to limiting its environmental impact, PoS will allow ethereum to dramatically reduce its rate of currency inflation since validators will have much lower overhead and will thus require smaller rewards to incentivize them to continue to serve as validators. Moreover, PoS will also reduce the incentive that validators have to centralize their influence. With decreased centralization comes increased security and, importantly, resistance to dreaded 51 percent attacks. Ethereum is not the first project to attempt to integrate a PoS consensus algorithm. However, most previous PoS implementations have been criticized Continue reading >>

Ethereum Price: What The Casper Update Means For Ethereum

Ethereum Price: What The Casper Update Means For Ethereum

Ethereum price: What the Casper update means for Ethereum Ethereum is on a charge right now after the first testnet of a major update was released. Here's what it means. Ethereum , while many believe is the future of the internet, in its current form still has problems handling capacity, relies on miners for proof of work and is quickly becoming more expensive for transactions. List of exchanges that allow you to buy Ethereum In December, the increasingly popular Ethereum-based game CryptoKitties brought in so much traffic that it completely overwhelmed the Ethereum network for 24 hours. There are several improvements on the roadmap to eventually bring Ethereum to the point where it can handle as many transactions per second as the Visa network, decentralised and at a cheaper price. The first of these is known as the Casper update, and its initial test network was just released, which is why Ethereum's price has been going through the roof. Casper, once it's integrated will turn Ethereum from a Proof of Work platform into a Proof of Stake, which will make everything much faster and cheaper as it continues to grow. Currently, the Proof of Work system Ethereum uses means miners are needed to solve complex algorithms to support consensus and keep the network running. In the Proof of Stake world, these miners will be replaced by "Stakers". These Stakers will stake their coins in special wallets, and be paid dividends from network fees based on how much ETH they stake. Stakers will need to have a minimum amount of ETH before they can take part in the consensus. It's not sure yet how much ETH will be needed, however Ethereum founder Vitalik Buterin has said it could be around 1,000 to begin with. The biggest change which will come from this is that it will make Ethereum mine Continue reading >>

Ethereum's Proof Of Stake Casper Testnet Nears Launch

Ethereum's Proof Of Stake Casper Testnet Nears Launch

One of the biggest upgrade in ethereum, and perhaps in the entire ecosystem, might be closer to implementation than previously thought, withLane Rettig, a researcher at the Ethereum Foundation, stating : Casper FFG testnet is coming. Weve got a three-node network working with two validators. Still a few bugs to work out. Whitepapers are cool and all but seeing this come to life is amazing. Casper Friendly Finality Gadget (FFG) is a hybrid Proof of Stake (PoS) and Proof of Work (PoW) implementation developed by Vitalik Buterin, ethereums inventor, and others. This implementation is apparently sufficiently advanced to the extent it could even be incorporated in the next ethereum upgrade, Constantinople Metropolis. According to Ethnews, Buterin said : Theoretically, Casper may well be at the stage where we may actually just try doing it for the next fork, even if that sounds ambitious. There is no estimated date for the second Metropolis fork as far as we are aware. Initially, the intention was to have just one Metropolis upgrade, but some aspects were taking far too long, while much else had been finalized. Developers therefore split it into Byzantium and Constantinople, with Byzantium going through just a few weeks ago. Constantinople is now expected next and might potentially incorporate Casper. The Casper testnet is, as the name says, an environment where they can test the first version of PoS. That means the code is not finalized, but has taken form rather than being at the theoretical design stage. The purpose of the testnet is to firstly ensure security and secondly to refine it fully as coders see how it works in a virtual lab environment. It is the last stage of any upgrade, before it goes to main-net, and indicates a live launch might be just months away. When e Continue reading >>

Ethereum Suprasses $1,000 On Strong Market And Launch Of Casper Testnet

Ethereum Suprasses $1,000 On Strong Market And Launch Of Casper Testnet

Ethereum Suprasses $1,000 On Strong Market and Launch of Casper Testnet Share on Facebook Share on Twitter Share on Google+ Share on LinkedIn If 2017 was the year of Bitcoin , the first few days of 2018 show that this year might be the year of everyone else. This should not be too shocking. At the start of 2017, Bitcoin enjoyed around 80% of the entire cryptocurrency market cap. Today, Bitcoins dominance by market cap hovers around 35%. Alternative digital currencies ( altcoins ) increased in popularity as different currencies ascend to prominence. At the beginning of December, Litecoin was a sub $100 currency. A powerful December price surge pushed its value up over $350 before settling to current prices around $300. Last month, Ripple usurped Ethereum for the #2 coin by market cap. This week Ripple had everyones attention. The enterprise-focused alt-coin was priced at less than $0.50 at the beginning of December. Its now trading at over $3. Ripples more than 35,000% rise in 2017 made it a late winner for the best performing crypto-asset in the world. Now, Ethereum is having its moment. After an early price hike in December, Ethereum was relatively stable throughout the month. Throughout December, Ethereum remained around $700. However, the new year brought new changes for Ethereum, and the price shot up about $100 a day. Ethereum spent most of 2017 as the #2 coin by market cap, posting YTD gains of more than 8,000%. On Thursday, Ethereum surpassed the $1,000 mark for the first time. Although Ripples recent run makes it the second most popular cryptocurrency by market cap, Ethereums price increase helped it creep closer to second place, a mantel that it held for most of 2017.

What Is Ethereum Casper Protocol? Crash Course

What Is Ethereum Casper Protocol? Crash Course

What is Ethereum Casper Protocol? Crash Course Angel Investors, Startups & Blockchain developers... If you are interested in Ethereum or Cryptocurrency in general, then you must be aware of the terms proof-of-stake and Ethereum Casper. There is no running away from these terms, they are everywhere. Now because there is so much data out there, anyone interested in the topic may go through paralysis via analysis. So, in this guide, we present to you the definitive guide to Casper and how it will change Ethereum forever. What is Ethereum Casper Protocol? Crash Course Most cryptocurrencies including Bitcoin run on proof-of-work. Proof-of-work as a process has the following steps to it: The miners solve cryptographic puzzles to mine a block to add to the blockchain . This process requires an immense amount of energy and computational usage. The puzzles have been designed in a way which makes it hard and taxing on the system. When a miner solves the puzzle, they present their block to the network for verification. Verifying whether the block belongs to the chain or not is an extremely simple process. That, in essence, is what the proof-of-work system is. Solving the puzzle is difficult but checking whether the solution is actually correct or not is easy. This is the system that Bitcoin and Ethereum (till now) have been using. However, there are some fundamental flaws in the system. As it turns out, there are quite a few problems with proof-of-work. First and foremost, proof of work is an extremely inefficient process because of the sheer amount of power and energy that it eats up. People and organizations that can afford faster and more powerful ASICs usually have a better chance of mining than the others. As a result of this, bitcoin isnt as decentralized as it wants to be.

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 >>

First Impressions Of Ethereums Casperproof Of Stake(pos)

First Impressions Of Ethereums Casperproof Of Stake(pos)

Vitalik Buterin and Virgil Griffith have introduced a proof of stake-based finality system capable of overlaying an existing proof of work (PoW) blockchain. In their paper [1], entitled Casper the Friendly Finality Gadget, Buterin and Griffith explain that the first version of Casper (within Ethereum) could take on the form of a hybrid PoW/PoS system. The first available release of the alpha Casper Friendly Finality Gadget (FFG) testnet, built on pyethereum, achieves this. This hybrid PoW/PoS vision, albeit with only 14 listed nodes at the time of writing, can be observed on the following Ethereum Network Status Site [2]. Installing Casper FFG on Ubuntu 16.04LTS Thankfully, the process of installing Casper FFG on Ubuntu as documented here [3] is relatively straight forward. This succinct installation process is thanks to the docker approach provided by Karl Floersch [4]. Participating in the validation PoSprocess At present, my most significant hurdle to running a validating Casper FFG testnet node is not brought about by the installation process or commands. It is brought about by the fact that a validating Casper FFG node, on the testnet, must provide a minimum deposit of 1, 500 Casper FFG testnet ETH in order to participate in the validation process. As we mentioned previously, Casper FFG is a hybrid PoW/PoS system and therefore the Casper FFG node is able to be run in mining mode. The following gist contains a list of commands for mining Casper FFG testnet ETH using Ubuntu 16.04LTS. The following gist contains a list of commands for checking Casper FFG testnet ETH account balance (during/after mining). Of course, whilst mining is an option, it would be ideal if participants willing to try out the alpha Casper FFG testnet could have immediate access to the required Continue reading >>

Vulnerable? Ethereum's Casper Tech Takes Criticism At Curacao Event

Vulnerable? Ethereum's Casper Tech Takes Criticism At Curacao Event

Vulnerable? Ethereum's Casper Tech Takes Criticism at Curacao Event Mar 2, 2018 at 20:00 UTC|UpdatedMar 4, 2018 at 12:22 UTC Is ethereum's biggest future upgrade "fundamentally vulnerable?" That was the claim put forward by distributed systems expert and founding VMware researcher Dahlia Malkhi on Friday, who used those exact words to describe ethereum's Casper protocol at Financial Cryptography 2018 in Curacao. During a keynote presentation, Malkhi's covered blockchain through the lens of a long-studied area of computer science that explores how nodes come to agreement. Still, it was her critical remarks on Casper, an upgrade that has promised to introduce a better, greener algorithm for the ethereum blockchain, that perhaps drew the most notice. Unlike bitcoin's pioneering proof-of-work system whereby miners expend real electricity and energy to verify blocks of transactions,proof-of-stake offers a kind of virtual mining, where the coins themselves are locked up (like capital in physical miners) and then perform computations. As such, proponents say proof-of-stake will have the same theoretical benefit to the system, without real-world power costs and environmental issues. But while the idea's opposition has been just as fierce,Malkhi's comments mark perhaps the first time a renownedcomputer science researcher has weighed in on the debate. "I think proof-of-stake is fundamentally vulnerable. You're giving authority to a group to call the shots [...] In my opinion, it's giving power to people who have lots of money. Yet, she softened the blow, adding that she believes Casper has led to "interesting" research that's fueled growing interest and innovation in the field of distributed systems. As someone who's been studying distributed systems for years, Malkhi's biggest Continue reading >>

How Ethereum's Casper Protocol Will Address Problems With Proof Of Stake

How Ethereum's Casper Protocol Will Address Problems With Proof Of Stake

How Ethereum's Casper Protocol Will Address Problems With Proof Of Stake Bitcoin and Ethereum both currently operate under a Proof of Work protocol. Ethereum is moving from Proof of Work towards Proof of Stake under its new Casper protocol. Despite its many benefits, the drawbacks of Proof of Stake have prevented its widespread adoption. Casper aims to solve Proof of Stake's drawbacks, resulting in an improvement over existing Proof of Work and Proof of Stake protocols. The updated protocol improves the long term outlook of Ethereum's valuation. An overarching problem that cryptocurrencies must address is called the Byzantine General's Problem . The Byzantine General's Problem essentially simplifies down to: How do you prevent data from being corrupted or falsified in a network where there are nodes that have economic incentive to lie about the data? In application to cryptocurrency, the problem boils down to preventing attackers from lying about a coin's ledger, given the economic incentive of doing so. We need a way to form consensus on the ledger because anyone can create a block, while we only want a unique chain, so we want a way to decide which block to trust. The two main schools of thought to solving the Byzantine General's Problem are Proof of Work (PoW) and Proof of Stake (PoS). Explicitly, a "proof of work" is a piece of data which is difficult (costly, time-consuming) to produce but easy for others to verify and which satisfies certain requirements. Producing a proof of work can be a random process with low probability so that a lot of trial and error is required on average before a valid proof of work is generated. Currently Bitcoin, Ethereum, and the vast majority of other cryptocurrencies utilize some form of proof of work. PoW (referring to the protocol Continue reading >>
