【Abstract】The research on the governing blockchain by blockchain supervision system is an important development trend of blockchain technology. In this system there is a supervisory blockchain managing and governing the supervised blockchain based on blockchain technology, results in a uniquely cross-blockchain demand to consensus mechanism for solving the trust problem between supervisory blockchain and supervised blockchain. To solve this problem, this paper proposes a cross-blockchain consensus mechanism based on smart contract and a set of smart contracts endorse the crossblockchain consensus. New consensus mechanism called Proof-of-EndorseContracts (PoEC) consensus, which firstly transfers the consensus reached in supervisory blockchain to supervised blockchain by supervisory nodes, then packages the supervisory block in supervisory blockchain and transmits it to the smart contract deployed in the supervised blockchain, finally miners in supervised blockchain will execute and package the new block according to the status of the smart contract. The core part of the consensus mechanism is Endorse Contracts which designed and implemented by us and verified the effectiveness through experiments. PoEC consensus mechanism and Endorse Contracts support the supervised blockchain to join the governing blockchain by blockchain system without changing the original consensus mechanism, which has the advantages of low cost, high scalability and being able to crossblockchain. This paper proves that our method can provide a feasible crossblockchain governance scheme for the field of blockchain governance.

【标题】PoEC:区块链治理区块链的跨区块链共识机制

【摘要】研究区块链监管体制治理区块链是区块链技术的一个重要发展趋势。在该系统中，有一个监管区块链管理和治理基于区块链技术的被监管区块链，产生了一个独特的跨区块链需求一致机制来解决监管区块链和被监管区块链之间的信任问题。为了解决这个问题，本文提出了一种基于智能契约的跨区块链共识机制，一组智能契约签署了跨区块链共识。一种新的共识机制被称为背书合同证明(PoEC)共识，它首先通过监管节点将监管区块链中达成的共识传输到监管区块链，然后将监管区块链中的监管块打包并传输到部署在监管区块链中的智能合同，最后监管区块链中的矿工将根据智能合同的状态执行并打包新的块。共识机制的核心部分是我们设计并实现的背书契约，并通过实验验证了其有效性。PoEC共识机制和背书契约支持被监管的区块链在不改变原有共识机制的情况下，通过区块链系统加入监管的区块链，具有低成本、高可扩展性、可跨区块链等优点。本文证明了我们的方法可以为区块链治理领域提供一个可行的跨区块链治理方案。
