Abstract: Based on the model of the new smart contract platform LSO design, which breaks the mechanism that the traditional smart contract can only be bound to one ledger system (Blockchain), and the standardization and microservice of smart contract, we propose the threebythree grid model of parallel game of the new smart contract. In this new model, each transaction is divided into three stages: before transaction, during transaction and after transaction. In each stage of the process, the buyer, the seller and the supervisor provide their own smart contracts by querying the smart contract library or publishing their own smart contracts to form smart contract groups. There is a competition and cooperation relationship between these smart contract groups. On the one hand, they are cooperating and on the other hand, they are playing games with each other, so as to ensure the fairness and efficiency of the transaction.

Key words: smart contract, three-by-three grid, parallel, game theory, transaction

摘要： 账本、智能合约、预言机并行系统(LedgersSmart ContractsOracle, LSO)设计打破传统智能合约只能和1个账本系统(区块链)死绑定的机制，在新型智能合约平台LSO模型和智能合约标准化、微服务化的基础上，提出新型智能合约的并行博弈的九宫格模型.在该新模型中，针对每次交易，分成交易前、交易中和交易后3段，在每段流程上，买方、卖方、监管方通过查询智能合约库或发布自己的智能合约，分别提供己方的智能合约，形成智能合约组，这些智能合约组之间存在竞合关系，一方面是合作，另一方面也是在互相博弈，从而保证兼顾交易的公平性和效率.
