摘要:

区块链上被交易的数字资产类型日渐丰富。非数字货币类的数字资产在创建时,存在创建的真实性和有效性问题。文章利用区块链技术构建信任机制,将数字资产创建视作评估行为的过程,设计处理评估行为的智能合约,搭建基于联盟成员信誉值的区块链系统。智能合约基于联盟成员的信誉值和给出的评估数据来完成数字资产创建。系统借助侧链技术转移创建的数字资产,从而能够为其他交易场景下的区块链增加真实性保证。实验证明该系统的运行具有低成本、存储空间不易扩张的特点。

关键词: 区块链, 信誉值, 数字资产, 侧链

Abstract:

The types of digital assets traded on the blockchain are getting richer. When digital assets other than cryptocurrencies are created, the problem of the authenticity and validity of the creation is produced. This paper builds trust mechanism based on blockchain technology, regards digital assets creation as the process of evaluating behaviors, designs smart contracts that deal with assessment behaviors, and builds a blockchain system based on reputation values of alliance members. The system uses sidechain technology to transfer created digital assets, which can increase the authenticity guarantee for blockchains in other trading scenarios. The experimental results show that the system has the characteristics that the cost is low and the storage space is not easy to expand.

Key words: blockchain, reputation, digital assets, sidechain
