Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] figure 1 It is a schematic flowchart of a method for accessing blockchain transaction records according to an embodiment of the present invention. Such as figure 1 As shown, the embodiment of the present invention can be applied to the entire production process composed of multiple participants, that is to say, it can be applied to a relatively closed private chain, or it can also be applied to a relatively open public chain. For each blockchain node ...

Abstract

The invention provides a method and a system for accessing transaction records of block chains. The method and the system are used for solving a problem that sensitive data may be leaked out in a scene where the block chains are applied in production cooperation since transaction data in a block chain account book is stored in a clear manner in the prior art can be freely accessed. The corresponding method and the corresponding system are provided. The method comprises steps of sending respective private keys of all block chain nodes to a management server for storage; the block chain nodes encrypt the to-be-stored transaction records by use of the respective public keys; when the transaction data needs to be accessed, a research request is given out to the management server; after the relation between a searcher and a searched person is judged, the transaction data is decrypted by use of the private keys and sent to the searcher nodes, thereby achieving data safety of the transactiondata in the block chain account book.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method and system for accessing block chain transaction records. Background technique [0002] With the advent of Bitcoin in 2009, blockchain technology rose to prominence. Blockchain technology, also known as "distributed ledger technology", is a technical solution for decentralization and collective maintenance of distributed ledgers. Its essence is a distributed database system that is collectively participated by multiple nodes. Blockchain is not a single technology, but the result of the integration of multiple technologies. Using blockchain technology to maintain a reliable and difficult-to-tamper account record can reduce the risk of trust and effectively reduce the collaboration of various participants. maintenance costs. In the actual application of the blockchain, each user will generate a pair of asymmetric key pairs for transaction signatures on the blockchai...
