BlockBeats reports that on August 7, Ethereum founder Vitalik Buterin expressed his surprise at seeing many mainstream Layer 2s reach Stage 1 'limited training rounds'. The next goal is to achieve fast withdrawals through the zero-knowledge proof system, which he believes is more important than reaching Stage 2 'no training rounds'. Quick withdrawal times are crucial and will lower the capital costs for liquidity providers. If native withdrawal times 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 issuing assets and the economic center of the Ethereum ecosystem.
To achieve this, we need to abandon 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 rapidly changing, as the 2-of-3 ZK + OP + TEE proof system strategy strikes a balance between security, speed, and maturity. In the long run, we will ultimately achieve nearly instantaneous native asset transfers across L2 via L1.
BlockBeats note: Stage 1 and Stage 2 are used to assess the maturity and decentralization level of Layer 2 rollups. Stage 1 is a limited training round, allowing some features with lower decentralization levels, but requiring rollups to meet basic security and functionality standards. Stage 2 is a no training round, requiring rollups to achieve stronger decentralization and security, approaching a state of complete decentralization.
