Ethereum 2.0, Casper and a tale of transformation and confusion

So, what is Casper PoS, and what does it bring to the Ethereum network? With the goal of becoming a worldwide adopted decentralized platform for DApps creation, the Ethereum team is getting rid of the pitfalls standing in its way:. The blockchain is a distributed ledger by nature, which means all participants hold a copy of all blocks on their computers. As the number of blocks is constantly growing, this slows down the work of the platform.

In terms of the processing time, Proof of Stake is more effective: on the EOS blockchain, for example, , transactions are processed per second. To speed up the platform, Vlad Zamfir suggested using sharding. The principle of sharding allows the processing of transactions concurrently, having shared them among the shard chains beforehand. Vlad points out that sharding can only be implemented on Proof-of-Stake protocol. How, exactly, will the implementation of these three technologies manage scalability?

You can find out in the Applicature blog. The hashrate is divided between three pools. Ethereum has faced the same issue:. In PoW, the pools with higher hashrates get an additional advantage: the mining gets cheaper.

This problem will be fixed by implementing Casper on Ethereum. There is a really small probability that the pool will succeed, as the final decision is always on every single miner; but even the possibility that someone has to coordinate miners makes some users feel uncomfortable with its continued usage in more valuable spheres.

What inspires people to turn to PoS consensus the most is the fact that electrical expenses will no longer be a thing. From now on, a minimum stake of 32 ETH will include you in a validator queueing pool and allow validating blocks, depending on your stake percentage. One more concern hindering Ethereum-based governance programs is security. This is why Vitalik Buterin came up with the Casper protocol, which will ensure security on Ethereum with the help of each node. Validators are interested in keeping the network alive, as empty stakes and double-spending will cause them to lose their stakes irreversibly.

The final reason for turning to Casper is full implementation of Proof of Stake with empty-stake and double-spending prevention, high-level responsibility of validators, and fast transaction processing. All of these factors will make Ethereum a super-computer for DApps creation and for launching massive projects in the future. The Ethereum blockchain, like the Bitcoin network, is supported by its users: miners.

The obvious disadvantage of PoW is its drastic electricity consumption. Research performed by Digiconomist has shown that by , miners on PoW-based platforms will consume as much electricity as the whole planet does now. The need to gain more computational power is leading to the centralization of the blockchain, which itself is decentralized. This could potentially lead to double-spending. An ordinary PoS consensus has structural and economic differences from Casper. Casper requires active participation from the validator.

For this and a bunch of other reasons, Vitalik claims PoS to be more efficient for network security. One more thing: colluding on an attack is impossible when the network follows PoW.

This is why detecting malicious nodes becomes incredibly hard. In the case of a PoS network, the system will track the nodes that verify suspicious transactions and will blame them for messing with the protocol.

In such case, those nodes will lose their deposited stakes. Currently, Ethereum users mine blocks by solving an NP-class puzzle with the help of their computational power. In order to become a validator in a new Beacon PoS chain, anyone in the network can deposit 32 ETH and start contributing to the security of the network. The Beacon chain will play two basic roles in the updated Ethereum network: it will be the main chain on Ethereum following PoS consensus, and it will link up all shard chains.

The decision of which blocks must be added to the main chain will be also made on the Beacon chain. Shard chains will store and share transactions, and will play a role in the scaling solution on Ethereum.

Theoretically, sharding implementation makes transaction processing faster. However, in reality, this tool is extremely difficult to apply due to a number of issues:. Discussions on the sharding mechanism became popular when it was mentioned as one of the methods of beating the scalability issue. However, the Ethereum blockchain is the only one that is ready to implement this technology, even though it has become so difficult. Exactly how sharding will become part of the Ethereum platform has not been revealed yet.

However, you can find more precise details on how it works in this article about the Raiden Network. A future consensus protocol of Ethereum is a smart contract that implements and monitors a Proof of stake consensus protocol. Who are validators, what is their commitment, and how does mining work with Casper?

Users who have made their deposits of 32 ETH and become validators have two voting responsibilities: propose and attest. The weight of each vote will be defined by the amount of stake the validator owns. The bigger stake, the higher the voting priority.

In Casper 2. This block will pass two rounds of voting by attester validators, and then will be included in the Beacon chain. Finally, the proposer validator connects to a Beacon chain node and proposes a block by calling an RPC function. Attesters are users who have the right to sign off on proposed blocks, or, in other words, vote for them. Implementing two rounds of voting, and penalizing maleficent validators will be a responsibility of Casper.

These two rounds of voting will build consensus on the Ethereum blockchain. A proposer validator chooses a block to be verified, or chooses an attester validator to choose the block that should be verified. As soon as the chosen block gets its two-thirds of the votes, it is a prepared block which will be voted upon again in a commitment round second round of voting. When the prepared block passes the second round of voting, it is finalized to the blockchain.

This validation process will continue on any appending block on the Ethereum blockchain. When voting, validators pay their two-thirds stake to submit their vote; however, if verified, the money is paid back.

This incentivizes validators to choose the blocks that are most likely to be added to the blockchain. Moreover, when validators vote, they reference their last prepared commitment block — these are the links of the blockchain. The first mention of Casper implementation on Ethereum goes back to , which followed with a testing period in The most frequently-asked question is how the Casper team is going to transfer the whole network to another consensus.

Vitalik Buterin mentioned that the implementation process becomes possible with the help of decreased rewards for mining. This will cause a mining freeze and make users concentrate on staking in further work on Ethereum. When Casper implementation reaches its final point, it will kill the era of mining on Ethereum, the market for ASIC-processor users, and will drastically change the economy of the platform.

Despite slashing, which will protect the network from messing with the system, there is still the threat of Ethereum becoming centralized. On Bitcoin, the biggest pools call the tune; on Ethereum after Casper implementation, the power will be in the hands of those with the biggest stake.

However, the necessary stake decreases to 32 ETH, which will increase the number of validators and prevent centralization. Users of the Ethereum platform faced serious scalability issues when the CryptoKitties game gained popularity and the network had to process a huge number of transactions fast. As it was said before, Casper is a smart contract on Ethereum that monitors Proof of Stake consensus. In order to transition the whole network from PoW to PoS, each fiftieth block will be a checkpoint with PoS implementation.

Moreover, the reward for mining will be lower, so users of the network will concentrate on staking instead of mining. All of the changes that Casper implementation brings will follow the ideology of Ethereum. There is not much information revealed on Casper, even though the testing period has passed.

PoW vs. PoS The Ethereum blockchain, like the Bitcoin network, is supported by its users: miners. PoW: In order to validate transactions and pack them in a block that will be added to the ledger, miners solve mathematical puzzles.

As network complexity and the number of transactions is constantly growing, the need for electricity grows, as well, which is quite costly. In , for example, Ethereum miners consumed the same amount of electricity as Cyprus and Cambodge. After a packed block gets into the network, thousands of miners verify it. Later, it is added to the distributed ledger as part of the blockchain.

PoS: Instead of using computational power to mine the block, users deposit their stake lock their coins. The bigger stake, the higher the possibility of mining the next block. Basically, this is the same costly approach as in PoW the rich become richer ; however, users do not use electricity.

The more stake you possess, the weightier your vote. Miners get rewards if the block is verified by other users. PoS vs.

Proof of Stake represents a class of consensus algorithms in which validators vote on the next block, and the weight of the vote depends upon the size of its stake. To participate in voting i. Proof of Stake PoS is a category of consensus algorithms for public blockchains that depend on a validator's economic stake in the network. In Proof of Work PoW based public blockchains e. Bitcoin and the current implementation of Ethereum , the algorithm rewards participants who solve cryptographic puzzles in order to validate transactions and create new blocks i.

Explaining Ethereum Casper Protocol

Ethereum and CasperLabs are in a race to the top of the cryptocurrency mountain. Ethereum Casper is an evolutionary tale of transformation in the blockchain network. So, you may also hear it referred to as Ethereum 2. The Ethereum Foundation wants this transition to take place to ultimately reduce electricity expenditure, improve speed and scalability. Ethereum has only been around since The reason for this is its blockchain design allows for easy deployment of decentralized applications dApps. In the pipeline are two co-developed Casper implementations helping transform the Ethereum ecosystem.

Where's Casper? Inside Ethereum's Race to Reinvent its Blockchain

Buterin kicked off his tweet storm at the beginning when Ethereum was in its ideation states. He also said that proof-of-work loyalists argue such attacks are unavoidable with the PoS system—primarily using this argument to dismiss the consensus mechanism. That said, Buterin tweeted:. We realized that we could deal with long range attacks by introducing an additional security assumption: that clients log on at least once every four months and deposits take four months to withdraw , and clients simply refuse to revert further than that. This was anathema to PoW proponents because it feels like a trust assumption: you need to get the blockchain from some trusted source when you sync for the first time.

Proof of Work: Environmental Impact

I recently gave a talk in Odessa, Ukraine on the basics of blockchains, cryptocurrencies, and cryptofinance. The audience was a mix of businessmen and developers, and both groups displayed lively interest in the topic. After the talk three characters approached me. They turned out to be the businessmen types. In an effort to protect and grow their capital, they told me, they invested in a moderately profitable Bitcoin mining rig, which I found to be a rather impressive achievement for someone whose main gig is chemical exports.

Outside the sprawling Prague Congress Centre, not only is the weather turning, but the cryptocurrency world is crashing down, as it has been for much of this year. Expectations for blockchain systems, sky-high just a year ago, are falling nearly as fast as prices for the coins based on them. But inside, the mood is rather different. On the contrary, there is lots of hugging, unicorn-themed clothing, and a sense of excitement about the future. Ethereum is already the most famous cryptocurrency after Bitcoin and the third largest in total value.

Mining has always been a business where the enormous effort required is often overlooked by the dogged human belief that quick riches are mere minutes away. This is as true of cryptocurrency mining as it is of precious metal and stones, and in both worlds, it is often some middleman who escapes with the profits, not the grizzled miner. Especially hardware. Ethereum mining was the hit business of the past few months. As more individual miners joined the flock, the demand for GPUs grew sharply. They started flying off the shelves often at starkly inflated prices, as computer parts resellers latched on to this new hunger.
