A blockchain rights management method and system

Abstract

The invention discloses a block chain authority management method and system. The method includes: identifying the authority change transaction sent by the user; wherein, the content of the authority change transaction includes the initiator, the user who changes the authority, the authority to be changed, and the corresponding change authority value; determine whether the initiator in the authority change transaction has authority change authority; if the initiator has authority change authority, modify the authority value of each user who needs to change authority to the corresponding change authority value, and execute the The permission change transaction of the block is recorded in the block; the transaction in the block is consensused, and the corresponding permission change transaction in the block takes effect after the consensus is passed. The authority management of this method is carried out directly in the blockchain without the need for external facilities, and is deeply integrated into the blockchain, which can perform all-round authority control on the blockchain. The change of authority needs to go through the consensus of the whole network, and Recorded in the blockchain, making the change record immutable and easy to audit.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain rights management method and system. Background technique [0002] The blockchain establishes a corresponding digital identity for each participant through cryptography. The digital identity of each participant consists of a pair of asymmetric public-private key pairs, where the public key can be generated through the private key. Participants use the private key to sign the information and send it to the blockchain. The blockchain recovers the public key based on the signature, and identifies the participant based on the public key (or its abstract), and further authenticates the participant's operation. [0003] When the public blockchain processes the information provided by the participants, it needs to consume a certain fee, which is usually a token in the blockchain. Information can only be entered into the blockchain if the participant has a su...

Problems solved by technology

The permission information and authentication logic in this scheme are all implemented at the smart contract level, so it is impossible to control the permissions below the smart contract level (such as sending transactions, obtaining blockchain status, etc.)

Applying this kind of scheme needs to bear risks such as transaction flood attack (recording a large number of useless transactions in the blockchain)
