摘要(Abstract)：

区块链是一种新型的分布式账本,具有高安全、防篡改和可追溯等诸多优点。然而,国家电网有限公司所属企业普遍采用联盟区块链技术,在与供应链中采用了其他结构区块链技术的外部企业进行价值交换和数据互通时会面临诸多困难。为此,提出一种适用于电力系统供应链的区块链跨链价值交换机制。该机制将侧链/中继和哈希锁定技术相结合,分别构造了联盟链侧和公链侧的合约模型,并通过基于委员会的验证机制确保交易的安全性和验证效率。实验结果表明,所设计的跨链机制在保证价值交换原子性和安全性的基础上具有良好的可扩展性,并且能较好地应用于电力供应链中。
Blockchain is a new type of distributed ledger, which has many advantages such as high security,tamper proof and traceability. However, enterprises affiliated with State Grid Corporation of China(SGCC)generally adopt the consortium blockchain technology and face many difficulties when they need to exchange value and data with the enterprises in its supply chain which uses the blockchain technique with different structures. Therefore, this paper proposes a blockchain-based cross-chain value exchange mechanism for power supply chain. This mechanism combines the side chain/relay and hash-locking technology to construct the contract models on the consortium blockchain side and the public blockchain side respectively, and the transaction security and verification efficiency are both guaranteed through a committee based verification mechanisms. The experimental results demonstrate that the cross-chain mechanism not only guarantees the atomicity and security of value exchange but also achieves good scalability and can be applied to power supply chain.
