本发明涉及区块链技术领域，具体涉及一种调用区块链上的智能合约的方法及系统。The invention relates to the technical field of block chains, in particular to a method and system for invoking smart contracts on block chains.
背景技术Background technique
区块链因其具备的去中心化、去信任、网络共识、分布式存储、信息不可篡改性等特性，越来越受到金融、保险等领域的公司的青睐，越来越多的银行机构以及互联网企业借助区块链开发基于区块链的项目。基于区块链的智能合约，是将业务规则执行进度以合约化、代码化的形式写入区块链中，不仅可以发挥智能合约在成本效率方面的优势，而且可以避免恶意行为对智能合约正常执行的干扰，使智能合约的整个执行过程透明可跟踪、不可篡改。Due to its characteristics of decentralization, trustlessness, network consensus, distributed storage, and immutable information, blockchain is more and more favored by companies in the fields of finance and insurance. More and more banking institutions and Internet companies use blockchain to develop blockchain-based projects. The smart contract based on the blockchain is to write the execution progress of the business rules into the blockchain in a contracted and coded form, which can not only take advantage of the cost efficiency of the smart contract, but also prevent malicious behavior from affecting the normal operation of the smart contract. Execution interference makes the entire execution process of smart contracts transparent, traceable, and tamper-proof.
在基于区块链的项目中，后台的业务处理是基于区块链上的智能合约来进行的，因此，需要一套业务层与区块链之间的交互框架以实现业务层对区块链上的智能合约的调用，以及实现将区块链上的智能合约经过业务处理生成的数据返回给业务层。目前，传统的业务层与区块链之间的交互框架，只是直接将数据写入区块链和直接从区块链读取数据，由于这种交互框架是进行脚本的直接调用，不利于基于区块链的项目的模块化设计，因此制约了多功能复杂型的项目的开发。In blockchain-based projects, the background business processing is based on smart contracts on the blockchain. Therefore, a set of interaction framework between the business layer and the blockchain is required to realize the interaction between the business layer and the blockchain. The call of the smart contract on the blockchain, and the realization of returning the data generated by the smart contract on the blockchain to the business layer after business processing. At present, the interaction framework between the traditional business layer and the blockchain only directly writes data into the blockchain and reads data directly from the blockchain. Since this interaction framework is a direct call of scripts, it is not conducive to The modular design of blockchain projects restricts the development of multifunctional and complex projects.
综上所述，如何提高一套完善的业务层与区块链之间的交互框架，成为业界亟待解决的问题。To sum up, how to improve a complete set of interaction framework between the business layer and the blockchain has become an urgent problem to be solved in the industry.
