The embodiment of the invention provides a transaction record confidentiality method and device in a block chain, a network and a storage medium, and the method comprises the steps that a first node in a first block chain calculates the Hash value of each transaction record on the first block chain in a preset time period; the first node generates a Merkle Tree of a Merkle tree based on the hash value of each transaction record; and the first node generates an alternative block based on the Merkle Tree, and broadcasts the alternative block to a second block chain, so that a second node in thesecond block chain obtains an accounting authority based on the alternative block, and generates a new block based on the accounting authority and the alternative block. According to the technical scheme provided by the embodiment of the invention, the transaction record in the block chain can be prevented from being leaked, and the confidentiality and security of the transaction record in the block chain are improved.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of block chains, and in particular to a method, device, network, and storage medium for keeping transaction records in the block chain secure. Background technique [0002] When the nodes in blockchain A provide accounting services for blockchain B, and blockchain B is a consortium chain or a private chain, if the candidate block generated by blockchain B containing transaction record details If it is directly sent to blockchain A for bookkeeping, the transaction records in the candidate block will be visible to the nodes in blockchain A, so that the transaction information of blockchain B can be easily leaked. Contents of the invention [0003] Embodiments of the present invention provide a transaction record confidentiality method, device, network and storage medium in a block chain, which are used to prevent the transaction record in the block chain from leaking and improve the...
