Vitalik: Ethereum will eventually achieve instant transfers of native assets across L2 through L1.

On August 7, Ethereum founder Vitalik Buterin stated that it is truly exciting to see many mainstream Layer 2s reach Stage 1 "limited training rounds." The next goal is to achieve fast withdrawals through a zero-knowledge proof system. He believes this is more important than reaching Stage 2 "no training rounds." The speed of withdrawals is crucial, as it will drop the capital costs for Liquidity Providers. If the native withdrawal time can be reduced to under 1 hour in the short term, and to 12 seconds in the medium term, it will further solidify Ethereum Layer 1 as the default platform for asset issuance and the economic center of the Ethereum ecosystem. To achieve this, we need to discard the Optimistic proof system, which essentially requires waiting several days to withdraw. Historically, zero-knowledge proof technology has been immature and costly, making Optimistic proof a wise and safe choice. However, this situation is changing rapidly, with the 2-of-3 ZK + OP + TEE proof system strategy balancing security, speed, and maturity. In the long run, we will ultimately achieve almost instant native asset transfers across L2 via L1. BlockBeats note: Stage 1 and Stage 2 are used to assess the maturity and decentralization of Layer 2 rollups. Stage 1 allows for some lower decentralization features but requires the rollup to meet basic security and functionality standards. Stage 2 requires the rollup to achieve stronger decentralization and security, approaching a fully decentralized state.
