Description

智能合约地址生成方法、装置、计算机设备及可读存储介质 技术领域
本发明涉及区块链领域，特别是涉及一种智能合约地址的生成方法、装置、计算机设备及可读存储介质。
背景技术
当前，区块链的发展越来越迅速，智能合约作为区块链中一项重要的技术，相比于常规合约，拥有数据透明、不可篡改、持久有效等特性，能够适用于更加广泛的领域。而为了在区块链中标记智能合约，需要给每个智能合约一个合约地址，合约地址与合约内容是一一对应的，其作用是用于合约存储检索和余额记账。
现有技术中，主流区块链项目的智能合约地址生成方式都是依赖于智能合约内容代码进行哈希，比较经典的，如以太坊，其智能合约地址就是采用智能合约内容代码加上随机数Nonce这两个关键信息进行哈希所得。然而，这种仅仅依赖于智能合约内容代码进行哈希从而生成智能合约地址的生成方式，生成的智能合约地址具有较大的随机性，从而无法从生成的智能合约地址中直接判断出智能合约发布者的账号地址，当区块链上其他用户需要确认智能合约发布者的身份时，必须通过系统查询该智能合约发布过程，才能判断出智能合约发布者的账户地址信息。
可见现有技术中，区块链上的用户无法直接从智能合约地址判断出该智能合约发布者的账户地址。另外，智能合约发布者也无法对其发布的智能合约进行管理。
发明内容
本发明实施例提供一种智能合约地址的生成方法，区块链上的用户能够通过该生成方法所得到的智能合约地址直接判断出该智能合约发布者的账户地址，无需通过系统查询。此外，针对同一用户发布的不同智能合约，依赖该生成方法得到的智能合约地址与该用户的账户地址相关，便于该用户对其发布的智能合约进行管理。
本发明实施例提供一种智能合约地址的生成方法，所述方法包括以下步骤：
根据智能合约发布者的账户地址生成账户地址哈希值；
根据智能合约内容代码生成智能合约哈希值；
根据所述账户地址哈希值和智能合约哈希值生成地址校检值；
根据所述账户地址哈希值的计算方法、所述智能合约哈希值的计算方法及所述地址校验值的计算方法，生成地址类型标识字符串；
将所述地址类型标识字符串、账户地址哈希值、智能合约哈希值与地址校验值进行组合生成智能合约地址。
本发明实施例还提供一种智能合约的生成装置，包括：
账户地址哈希单元，用于根据智能合约发布者的账户地址生成账户地址哈希值；
智能合约哈希单元，用于根据智能合约内容代码生成智能合约哈希值；
地址校验值单元，用于根据所述账户地址哈希值和智能合约哈希值生成地址校检值；

将所述账号地址哈希值以及智能合约哈希值进行组合。
根据所述账号地址哈希值以及智能合约哈希值组合后的序列生成账号地址与智能合约组合哈希值。
将上述账号地址与智能合约组合哈希值取前八位数值记为地址校检值。
所述根据所述账号地址哈希值以及智能合约哈希值组合后的序列生成账号地址与智能合约组合哈希值的计算方法包括：使用sha256(Secure Hash Algorithm，安全散列算法，一种哈希算法)、RIPEMD160(RACE Integrity Primitives Evaluation Message Digest，RACE原始完整性校验消息摘要，一种哈希算法)等哈希算法中的一种或多种组合以及一次或多次重复进行哈希计算。
步骤S104，根据所述账户地址哈希值的计算方法、所述智能合约哈希值的计算方法及所述地址校验值的计算方法，生成地址类型标识字符串。
在本发明实施例中，所述账户地址哈希值的计算方法、所述智能合约哈希值的计算方法及所述地址校验值的计算方法均预设有对应的字符串，不同的计算方法对应着不同的字符串。
