Abstract: 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.

Abstract: Disclosed is a method and device for preventing blockchain forking. The method includes: selecting s consecutive blocks Bn to Bn+s; generating a key pair for block Bm by a node An that creates the block Bn; holding the node An active in the blockchain's continuously generating blocks Bn+1 to Bn+s until the block Bn+s of s consecutive blocks becomes tamper-proof; in response to that, signing on the block Ban+s with the private key PK′n; in response to the blockchain's subsequently generating a block Bm(m>n+s), placing the signature in Bm; making nodes creating each of the s blocks Bn to Bn+s all execute afore-mentioned steps, thereby forming multiple backlinks associated with the blockchain's block size. The number of backlinks is used for determining blockchain forking by a newly-added node creating a new block.

Abstract: Disclosed is a public random number generation method based on a blockchain, including: selecting a node group G containing N trusted nodes; determining a first time point tm and a second time point tn respectively for generating an m-th/n-th block, wherein the former is earlier, and the m-th block is fixed and cannot be tampered at tn; at the first time point tm, enabling each of the N trusted nodes to separately generate a sub-random number rj as a component forming a random number X, wherein j=1, 2, . . . , N, on which delayed encryption is performed, with corresponding results placed in the m-th block; and at the second time point tn, decrypting the delayed encryption results to obtain decrypted data of them all that are all of sub-random number rj, on which operation is performed to obtain the random number X as a final available public random number.
