摘　　要：为将区块链交易应用于日常支付场景中,降低区块链交易的使用门槛,提出一种基于商户联盟的区块链快速交易方案。该方案充分考虑了日常支付的现实场景需求,将付款与交易分离,缩短了支付确认时延。针对现有工作中在押金以及交易手续费方面的不足,一方面通过设计筹码交易机制,释放系统内存在的被锁定资金,降低区块链交易在日常支付场景中的使用门槛;另一方面通过设计交易结算机制,将消费者结算与商户结算阶段解耦,增加商户结算的灵活性,降低交易手续费。考虑到交易过程中可能存在的作恶行为,本方案通过设计状态安全同步机制,为区块链快速交易提供安全保障。将本文方案与其他工作方案进行对比分析,结果表明,本文方案需要的手续费与押金更少,更加符合日常支付场景。In order to apply blockchain transactions to daily payment scenarios and reduce the use threshold of blockchain transactions, this paper proposes a scheme based on merchant alliance for fast blockchain transactions. The scheme fully considers the actual scene requirements of daily payment and separates payment from transaction, so as to shorten the delay of payment confirmation. In view of the shortcomings in locked funds and transaction fee in the existing work, on the one hand,we design a chip trading mechanism to release the locked funds in the system and to reduce the threshold for the use of blockchain in daily payment scenarios. On the other hand,we separate merchant settlement from consumer settlement to reduce the transaction fee by designing transaction settlement mechanism. Considering the possible evil behavior in the transaction process, we provide security guarantee for the fast blockchain transaction by designing the state synchronization mechanism. Comparing the scheme with other work schemes, the results show that the scheme requires less handling fee and locked funds,which is more suitable for daily payment scenarios.
