The invention provides a block data storage system and method for a block chain alliance chain. The system comprises a third-party platform, a franchisee main node, a plurality of signer nodes and theparticipant nodes, the franchisee master node receives a request for creating a transaction and a block sent by a third-party platform, generates the transaction and service data of the global attributes after the signature verification of the service data passes and stores the service data of the global attributes and the original service data of the local attributes; the signer node sends a block generation request response message to the franchisee main node after the consistency consensus verification of the transaction and the business data passes; and the franchisee node generates a block comprising the transaction data, the business data and the evidence data when determining that the number of the plurality of generation block request response messages meets the signature number required by the consistency consensus, and synchronizes the blocks to the signer node and the participant nodes. According to the scheme, the requirement for the storage space of each node of the blockchain platform is reduced, and the asset data can be simply and conveniently used.
Description
technical field [0001] The present invention relates to the technical field of blockchain alliance main chain, in particular to a block data storage system and method of blockchain alliance chain. Background technique [0002] Based on blockchain technology, there are three forms of public chain, alliance chain and private chain. The essence of the alliance chain is still a private chain, but it is larger than the private chain developed by a single small organization, but not as big as the public chain. It can be understood that it is a blockchain between the private chain and the public chain, and refers to a blockchain whose consensus process is controlled by pre-selected nodes. As a partially decentralized main chain, when storing block data, it must also meet the storage requirements of the distributed ledger. In the case of big data and multi-node business scenarios, there are two existing solutions for the storage of distributed ledgers: the first is an asset-heavy m...
