Vitalik Buterin: 混合思路：乐观+ZK，治理只裁决两者之间的bug 1.发布区块 2. 等待 24 小时进行欺诈挑战。 3a。如果没有挑战，发布 ZK SNARK，最终确定。 3b。如果有挑战，请根据（挑战游戏、ZK SNARK、治理）的 2-of-3 决定 https://t.co/KWuk4mZTQa 引用@kelvinfichter 的推文：但是基岩没有理由不能使用零知识证明系统来代替??。我们认为 Optimistic Rollups 目前比 ZK 同类产品具有巨大优势，但 Bedrock 旨在使 Optimistic 和 ZK 之间的无缝过渡成为可能。

原推：Hybrid idea: optimistic + ZK, governance only adjudicates bugs between the two

1. Publish block

2. Wait 24h for fraud challenges.

3a. If no challenge, publish ZK SNARK, finalize.

3b. If there is a challenge, decide based on 2-of-3 of (challenge game, ZK SNARK, governance) https://t.co/KWuk4mZTQa

Quoted tweet from @kelvinfichter:

But there’s no reason why Bedrock can’t use a ZK proof System instead ??. We think Optimistic Rollups currently have massive advantages over their ZK counterparts, but Bedrock has been designed to make a seamless transition between Optimistic and ZK possible.
