Vitalik: Ethereum will eventually achieve native asset transfers across L2 through L1

ChainCatcher news, according to a post by Ethereum founder Vitalik Buterin, it is truly exciting to see many mainstream Layer 2 solutions reach Stage 1 "limited training rounds." The next goal is to achieve fast (less than 1 hour) withdrawal times through validity (also known as zero-knowledge proof) systems. It is believed that this is more important than reaching Stage 2 "no training rounds." Fast withdrawal times are crucial as they will reduce the capital costs for liquidity providers. If the native withdrawal time can be shortened 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 almost instantaneous native asset transfers across L2 via L1.

ChainCatcher Note: Stage 1 and Stage 2 are used to assess the maturity and decentralization level of Layer 2 rollups. Stage 1 is for limited training rounds, allowing some features with lower degrees of decentralization but requiring the rollup to meet basic security and functionality standards. Stage 2 is for no training rounds, requiring the rollup to achieve stronger decentralization and security, approaching a fully decentralized state.
