Problems solved by technology

[0003] Consortium chains usually require a centralized certificate authority (Certificate Authority, CA) server to be responsible for authority control, which reduces the reliability brought by the natural distributed trust mechanism of the blockchain, and the open nature of the public chain leads to illegal Transactions are very easy to breed

Embodiment Construction

[0032] After research, the inventor also found that the consortium chain usually requires a centralized certificate authority (Certificate Authority, CA) server to be responsible for authority control, which reduces the reliability brought by the natural distributed trust mechanism of the blockchain, while The completely open nature of the public chain makes it very easy to breed illegal transactions.

[0033] In view of the above situation, the embodiment of this application proposes a blockchain authority management method and a blockchain system, which can utilize the natural distributed trust mechanism of the blockchain system to achieve flexible authority management. On the one hand, compared with the centralized CA It is more reliable. On the other hand, using authority management instead of a fully open mechanism can avoid the breeding of illegal transactions to a certain extent.

[0034] Firstly, the blockchain system proposed in the embodiment of this application is i...

Abstract

Embodiments of the present application provide a blockchain authority management method and a blockchain system, the method includes: the first node receives an operation request for the second node, the first node is a node manager in the blockchain system, and the second The node type of the node is a super node, a backbone node or a service node; the first node requests a vote for the node operation, and sends the first voting request to other node managers, and obtains the voting results and voting signatures fed back by other node managers. The obtained voting results and voting signatures are packaged into the first block and released to the blockchain system; each blockchain node verifies the voting signature in the block, and if it passes, it will be appended to the local ledger; If more than half of the voting results in the first block are passed, the node operation request will be responded to. In this way, the natural distributed trust mechanism of the blockchain system can be used to achieve flexible and reliable authority control.

Description

technical field [0001] This application relates to block chain technology, specifically, to a block chain authority management method and block chain system. Background technique [0002] Blockchain technology is a ledger technology jointly maintained by multiple parties. It is composed of consensus mechanism, cryptographic algorithm, network routing, contract script and other technologies. It has the technical characteristics of distributed credibility, difficult to tamper, and multi-party maintenance. These technical characteristics make the blockchain considered one of the most disruptive technologies since the popularization of the Internet, and has attracted great attention from all parties around the world. [0003] Consortium chains usually require a centralized certificate authority (Certificate Authority, CA) server to be responsible for authority control, which reduces the reliability brought by the natural distributed trust mechanism of the blockchain, and the ope...
