Abstract: It is impossible for ordinary users to identify whether the mobile application market is credible and the malicious behavior in the mobile market is difficult to trace. This paper proposes a solution for the trusted mobile application market based on blockchain. Blockchains have decentralized, tamper-proof, traceable security features based on which the publication and dissemination of applications are implemented. This solution builds a trusted bridge among developer, application market and user. It also ensures that the source of the mobile application can be verified, the integrity is verifiable, the trajectory is traceable, and malicious behavior is difficult to deny. The analysis shows that the scheme can establish a credible mobile application ecosystem and improve the security of mobile applications.

Key words: blockchain, mobile application market, trusted application
