The present invention discloses a decentralized open-source software protocol for open-source software and developers globally. The protocol is based on a non-fungible token (NFT) associated with a commit of a source code developed in collaboration, such as an open-source software code. With this protocol, contributors of an open-source software code are incentivized to take on well-specified tasks and then claim their contributions to development in the form of the NFT. A trusted transparency centre (TC) is proposed in the present invention as a core technology to enable trusted software analysis so as to yield the fundamental information and value of a given commit in a repository.
