CoinVoice has learned that Ethereum founder Vitalik Buterin stated that it is surprising to see many mainstream Layer 2 solutions reach Stage 1, the 'Limited Training Rounds' phase. The next goal is to achieve fast withdrawal times (less than 1 hour) through validity (also known as zero-knowledge proof) systems. He believes this is more important than reaching Stage 2, 'No Training Rounds.' Fast withdrawal times are crucial and will reduce the capital costs for liquidity providers. If native withdrawal times 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 for withdrawals. Historically, zero-knowledge proof technology has been immature and costly, making Optimistic proofs a wise and safe choice. However, this situation is rapidly changing, and 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. CoinVoice note: Stage 1 and Stage 2 are used to assess the maturity and decentralization of Layer 2 rollups. Stage 1 is for limited training rounds, allowing some features with lower levels of decentralization, but requiring rollups to meet basic security and functionality standards. Stage 2 is for no training rounds, requiring rollups to achieve stronger decentralization and security, approaching a state of complete decentralization. [Original link]
