The embodiment of the invention provides a data management method and device for a blockchain system, a medium and electronic equipment. The blockchain system comprises an account keeping sub-networkand a service node sub-network. The data management method comprises the steps of: after generating first data blocks at account keeping nodes, and adding first key information for verifying block heads of second data blocks generated after the first data blocks into block heads of the first data blocks; generating signatures corresponding to the first data blocks, and adding the signatures corresponding to the first data blocks into the block heads of the first data blocks; and releasing the block heads of the first data blocks to the service node sub-network so as to enable service nodes toverify the block heads of the first data blocks, and after verification is passed, acquiring the first key information to verify the block heads of the second data blocks. According to the technical scheme of the embodiment of the invention, the aim of flexibly updating a block head verification key is fulfilled, and security of block head data is effectively ensured.
Description
technical field [0001] The present invention relates to the technical field of computer and communication, in particular, to a data management method, device, medium and electronic equipment of a block chain system. Background technique [0002] The blockchain network is an end-to-end decentralized network composed of many nodes. Each node is allowed to obtain a complete copy of the database, that is, all information between nodes is completely shared, and each node is based on a set of consensus mechanisms. To jointly maintain the entire blockchain. [0003] In an application scenario of the blockchain system, it may be necessary to send data in the blockchain network to service nodes outside the blockchain network. Signature, so that business nodes can verify the data, and how to avoid data insecurity due to the leakage of the signature key has become a technical problem that needs to be solved urgently.
