op-rollup

交易执行和聚合(Transaction execution and aggregation)

  • 由验证器节点打包执行二层交易, 对底层数据压缩后批量发布到主链
  • 验证器节点可以单个中心化控制, 或者多个采用类POS质押相互监督
  • 主链对压缩后的数据只做存储记录, 不会导致状态变化

状态提交(State commitments)

  • 提交状态数据Merkle root, 涉及账户, 余额, 合约逻辑等, 记录状态变化过程
  • 提交区块交易Merkle root, 用于交易存在Merkle proof

欺诈证明(Fraud proving)

主链记录了二层每一次提交的状态根, 在最终确认前需要经过挑战期, 任意第三方可以对状态更新提出质疑, 并提交欺诈证明, 以更新正确的状态

  • Optimism是将存在争议的交易提交到主链, 进行重新执行, 主链比较已提交和执行后的状态, 直接仲裁
  • Aribitrum采用多轮交互, 将争议范围进行二分缩小, 到单条指令级别, 再由主链执行单条执行, 根据结果完成仲裁
  • 上述方法均依赖于派生了新的虚拟机(OVM/AVM), 在主链合约中即能完成二层交易的重新执行或指令级别争议仲裁

matic

matic混合了侧链和plasma技术, 实现了侧链高并发的同时也保证了一定的去中心化安全性

bor

侧链节点实现, 对共识进行了调整, 提高了出块速度和并发

heimdall

共识层节点实现, 协调侧链和主链状态更新等

  • 在主链进行POS质押, 构成验证节点池子
  • 批量对bor的区块进行验证并, 并计算批次内所有区块哈希 merkle root , 共识后(2n/3+1)提交到主链

ethereum

作为matic主链, 部署了相关合约, 用于质押, 跨链, 侧链状态记录持久化

总结

相较于op-rollup基于EVM的欺诈证明, matic框架更适用于当前平行链模式, 可以做类似的实现

  • 平行链独立出块, 涉及挖矿打包共识
  • 向主链批量提交数据, 涉及交易等数据压缩, 提交共识
  • 协调主链和平行链状态更新, 涉及质押,跨链等功能
