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
