Ethereum 2.0- Vitalik Buterin’s Roadmap

The Ethereum Killer Is Ethereum 2.0: Vitalik Buterin’s Roadmap

Talking on November 25 in BeyondBlock Taipei 2017, Ethereum Creator and co-founder Vitalik Buterin summarized his vision for Ethereum 2.0. He explained major changes in Ethereum’s architecture which are very likely to be implemented during the upcoming few years to boost Ethereum concerning privacy, security (consensus security and smart deal security) and, needless to say, scalability, that had been the primary attention of Buterin’s talk.

Buterin does not look worried about competitions. “The Ethereum killer is Ethereum, the Ethereum of all China is Ethereum, the Ethereum of Taiwan is Ethereum… 2.0,” he explained.

The simple fact that Ethereum is flourishing appears to affirm Buterin’s optimism. ETH’s price has been relentlessly climbing, lately reaching nearly $500, and Ethereum is managing more trades than all other big blockchains combined.

Decentralization, scalability, and security are one of the vital attributes that blockchain systems ought to possess, but there are battles. Off-chain options are helpful but limited. In accordance with Buterin, it is quite simple to get two of those properties but quite hard to have all three. But, Ethereum’s ambitious target should be that of accomplishing all three at exactly the exact same moment.


Sharding — splitting a blockchain system into several smaller part networks (called shards) capable of processing trades in parallel — is regarded as a promising means to attain high throughputs like the tens of thousands of trades per second of conventional payment systems like Visa and MasterCard.

“You can imagine [sharding] as, at a fairly easy version, developing a blockchain in which you have, let us say, a hundred distinct universes, and every one of these universes is not the same accounts area,” explained Buterin. “So you can get an account in a certain world or you could have a contract in a certain world and you’re able to send a trade in some world, and if you send a trade in a certain world it only impacts stuff in some world.

“However, these sort of 100 universes aren’t only different blockchains; they’re systems which are additionally connected with one another,” lasted Buterin. “Especially, they discuss consensus. So to be able to break even among these, you need to break the entire thing.”

Buterin proceeded to explain relatively simple and much more sophisticated tactics to execute sharding from the Ethereum blockchain, representing a sharding roadmap that foresees, at least originally, the production of new “universes” which do not affect the principal chain whilst allowing iterative experimentation, like introducing high levels of scalability, starting with “quadratic scalability as habitats affirm particular shards and behave as light customers for different shards.”


Buterin noted that zero-knowledge evidence (zk-Snarks) solitude technology equal to Zcash has been executed in the current “Byzantium” Ethereum update, offering program developers new tactics to implement tighter privacy. These brand new privacy tools will allow showing trades to certain parties while concealing them from public opinion. Buterin went up to state that the privacy problem is currently three-quarters of their way to being solved.

Proof of Work vs. Proof of Stake

A significant update to Ethereum is going to be the debut of Proof of Stake (PoS) in Casper that, based on Buterin, could be prepared by next summer. Together with the initial launch of Casper, Ethereum will transition out of pure Proof of Work (PoW) to hybrids PoW/PoS. “In this strategy, each one of the proof-of-work mechanics will continue to exist, but added proof-of-stake mechanics will probably be inserted,” mentioned Buterin.

The chief reason why PoS is regarded as an essential development is, clearly, the requirement to decrease the energy needs of PoW blockchains such as the present variants of Ethereum and Bitcoin. A recent report claims that Bitcoin mining absorbs as much electricity in annually as 159 nations, which is obviously far too much, and Buterin confessed that the current Ethereum is not any better than Bitcoin in this regard.

Smart Contract Security

Bright contracts executed using Turing-complete programming languages are arguably the major innovation introduced by Ethereum. While clever contracts are discovering countless applications and transferring a great deal of money, the safety and security of Ethereum smart contracts are contested. Buterin verified that Ethereum will gradually introduce formal confirmation for clever contracts and that a new Python-like smart-contract programming language — dubbed “Viper” — has been implemented to permit the creation of more powerful Ethereum applications.

While Buterin has not stated anything that he hasn’t said in previous conversations and documents, his BeyondBlock conversation served as a helpful affirmation and overview of the demanding Ethereum development roadmap.

Besides Buterin’s discussion, all of the discussions given by BeyondBlock Taipei 2017 are contained in the entire video records of the afternoon session and the afternoon session.
