Vitalik Buterin outlines ‘endgame’ roadmap for ETH 2.0


The co-founder of Ethereum, Vitalik Buterin, has presented his vision for a “plausible path” for Eth2, describing a future in which the world’s largest smart-contract platform can scale while retaining high standards of trustlessness and censorship resistance.

In a post titled “Endgame,” Buterin suggested a thought experiment for how the average massive blockchain, defined by very high block frequency, big block size, and thousands of transactions per second, could be sufficiently trustless and censorship-resistant. The trade-off for this level of scalability is the centralization of block manufacture. Buterin’s suggestions do not address the issue of centralization, but they do provide a roadmap for execution, as outlined in the blog post.

Buterin proposed “a second tier of staking, with low resource needs” for distributed block validation as a solution. “Introduce fraud-proof or ZK-SNARKS to allow users to confirm block validity directly (and affordably)”. “Add auxiliary transaction channels to circumvent censorship” and “provide data availability sampling to help users check block availability”.

“We obtain a chain where block production still centralised. But block validation is trustless and very decentralised. As well, specific anti-censorship magic prohibits block producers from filtering,” Buterin noted with these changes.

No single rollup is able to capture even a small portion of Ethereum activity

Buterin asserted that block generation will remain centralised despite the adoption of so-called “rollups,” which are layer-two solutions that execute transactions outside of the main Ethereum chain. (Incidentally, in October 2020, Buterin laid forth a rollup-centric Ethereum strategy).

“No single rollup is able to capture even a small portion of Ethereum activity”. Rather, they all max out at a few hundred transactions per second”, he explained. While rollups appear to help with distributed block generation, decentralisation may not be sustainable. Due to the possibility of cross-domain maximal extractable revenue, or MEV. MEV refers to the maximum amount of value that possibly generated through block production. In addition to conventional block rewards and gas taxes, as the name suggests.

Regardless of the network’s path to scalability, the Ethereum co-founder concluded that block production will almost certainly become centralised. According to him, Ethereum’s rollup-centric roadmap has the advantage of being available to all futures.

Since November 2020, when the system began its gradual shift to proof-of-stake, there has been a lot of buzz about Ethereum. In August of this year, the much-anticipated London hard fork was implemented, putting ETH on the path to becoming a deflationary asset. EIP-1559, a hard fork aimed at reforming the network’s fee market, implemented with the hard fork. Since the EIP-1559 went into force, almost 1 million ETH has been burned.
