Blockchain technology has been exploited to build next-generation applications with its decentralised nature. However, serious concerns are raised about the trustworthiness of the blockchain due to the virtue of the vulnerabilities in on-chain algorithmic mechanisms and tedious debates in the off-chain community. Accordingly, the governance of blockchain has received great attention recently to enhance the trustworthiness of all decisions directing a blockchain platform. This research domain is still immature, however, and there is a lack of systematic knowledge to guide the practitioners on how to design and implement governance methods for blockchain. Therefore, we have performed an SLR to understand the state-of-art in this topic, and extractd 14 governance patterns regarding the four layers (i.e., data, platform, application, and community) of blockchain ecosystem. To effectively use the discovered patterns, we demonstrate lifecycle stages of these four layers and involved stakeholders in blockchain ecosystem, as a guidance for effective use of the patterns, which has yet to be presented and introduced in existing works of this topic.
