Abstract: Blockchain has the advantages of distribution, immutability, decentralization, and traceability, but short of implementing.
Smart contract is a decent solution to make up for this deficiency. However, smart contracts also struggle in deploying and monitoring.
Inspired by the DevOps tools that support continuous delivery and continuous monitoring for microservices, a framework is proposed to
architect smart contracts using microservices. Besides, a prototype platform (Mictract) is implemented in which DevOps tools were
aggregated to support smart contracts deploying and monitoring. The case study performed in Marbles of Hyperledger Fabric shows that
the proposed framework and the prototype platform significantly improve the automation level to deploy and monitor smart contracts.
Key words: blockchain; smart contract; microservice; DevOps; automation
