Access method and device based on block chain data, processor and electronic equipment

Abstract

The invention discloses an access method and device based on block chain data, a processor and electronic equipment, and relates to the technical field of block chains, and the method comprises the steps: obtaining a first transaction request of a target user for the block chain data; according to the target identity ID, the prime number set and the prime number field, determining whether the target user has an effective operation authority for the block chain data; if the target user has the effective operation authority, determining whether the transaction request I is in an authority permission range or not according to a target attribute list and a preset attribute control list; if the first transaction request is within the permission range, obtaining target data information; and decrypting the target data information through the target attribute private key of the target user to obtain initial data information. According to the method and the device, the problem that the efficiency of acquiring the block chain data access authority is relatively low due to the fact that various data access strategies are realized by deploying complex authority control logic in an intelligent contract layer in the related technology is solved.

Description

technical field [0001] The present application relates to the field of blockchain technology, and in particular, to a method and device for accessing blockchain data, a processor, and an electronic device. Background technique [0002] The blockchain network is a common accounting solution that uses P2P communication technology to achieve peer-to-peer communication, uses a consensus mechanism to achieve accounting legitimacy, and uses a chain structure to store data. At present, when there is a data isolation requirement on the business chain, different application channels are usually established to isolate different data ledgers. When there are multiple data isolation requirements on the chain in the same business scenario, or there are multiple data sharing strategies among alliance organizations, it is necessary to create different application channels or establish copy data of the ledger that satisfies multiple access strategies, which needs to be implemented at the con...
