After roughly looking at Roadmap, which is streamlining consensus on Ethereum, it is indeed starting to make efforts as Vitalik Buterin said.Share the highlights I’ve seen:
1) Ethereum’s past updates and iterations have been repaired, resulting in the accumulation of too much technical debt. However, this roadmap at least shows that Ethereum is going to really “turn back”, which is quite bold to switch from POW to POS.
Even BLS elliptic curve signature has been given up and has to be signed directly, because although BLS has become a contributor to the implementation of beacon chains, it has become the biggest obstacle in cost and efficiency in the issue of comprehensive ZKization.The goal is to make Ethereum truly a chain of ZK-Native;
2) We actually explored 6 zkVM technology routes at the same time, not for general computing, but for the ultimate optimization of the scenario of “signature aggregation”.SP1 (Succinct), OpenVM’s general customized solutions, Binius and Hashcaster’s specialized solutions are all being promoted at the same time.
This actually introduces a zkVM horse racing mechanism, with the goal of maximizing the performance of Ethereum zkVM.But I noticed that RISC Zero, the founder of zkVM, seems to be absent, but if you think about it carefully, you can understand that Risc Zero wants to serve a larger general zkVM market. Ethereum only needs to make extreme customization in signature aggregation. If the pattern is big, it will be disdain to do special optimizations;
3) The pledge threshold is reduced from 32ETH to 1ETH, and the block output is reduced from 12s to 4s.These performance optimizations are direct manifest effects after the hash signature + zkVM upgrade, and has also achieved the further high-performance mission of Ethereum L1.
But this brings a question: What value does general layer2 have if it is just simple, cheaper and more efficient?There is only one way before them. If you switch to Specfic-Chain (game chain, payment chain?), or Based Rollup modes will become mainstream. After all, after L1’s performance is improved, it is more reasonable to hand Sequencer over L1.
above.
In general, I feel that Ethereum’s streamlined consensus roadmap is no different from Solana’s recent Alpenglow and Firedancer upgrade routes. In essence, it is achieved through streamlining consensus to achieve performance leap.
However, Ethereum has accumulated too much technical debt in the past, and it will take at least 4-5 years to reconstruct.
