Embodiment Construction

[0046] The technical solutions in the embodiments of the present invention will be described clearly and in detail below with reference to the drawings in the embodiments of the present invention. The described embodiments are only some of the embodiments of the invention.

[0047] The technical scheme that the present invention solves the problems of the technologies described above is:

[0048] figure 1 It is a flow chart based on the Ripple consensus mechanism model based on extended trusted authentication in the consortium blockchain provided by the embodiment of the present invention. The method comprises 5 steps:

[0049] Step 1, the supervisory node performs identity registration, management and certificate issuance for regular nodes in the blockchain, and provides identity authentication credentials for registered nodes;

[0050] Step 2, all regular nodes collect transaction requests, generate transaction candidate sets, verify the initiators of transaction requests...

Abstract

The invention requests to protect an extended trusted authentication Rayleigh consensus method based on an alliance block chain. A supervision node is set to issue a digital certificate to a voting node, and the digital certificate is used to replace a unique node list (UNL). For a delay test of an active trusted node and all newly added nodes, a new node in a tolerable time period in the delay test is added to the block chain. According to the algorithm model, the problem that nodes are difficult to add and delete in the Rayleigh consensus algorithm is solved to a certain extent; the expandability of the Rayleigh consensus algorithm applied to the alliance block chain is enhanced on the premise of sacrificing the communication cost, and the total throughput of the algorithm is improved. Because the consensus reaching time required by the Rayleigh consensus algorithm is short and the time delay difference is within a millisecond-level range, the method can be suitable for most of Internet of Things application scenes in an expansible environment.

Description

technical field [0001] The invention belongs to the field of block chains, and in particular relates to a Ripple consensus mechanism based on extended trusted identity authentication in alliance block chains. Background technique [0002] As a point-to-point distributed system, blockchain has high security and decentralized storage functions, and has encryption and fault-tolerant technology. In recent years, blockchain has become a research hotspot in the financial field and many other fields. In addition to its application in the traditional financial currency field, it has applications in digital currency, bills, liquidation, digital asset transactions, supply chain finance, government affairs, people's livelihood and business. The underlying architecture also has good application potential. With the continuous development and improvement of blockchain technology, more and more application projects have been implemented, and blockchain has also got rid of the limitations ...
