Credit-based blockchain consensus method for large-scale e-commerce

Abstract

The invention discloses a credit-based blockchain consensus method for large-scale e-commerce. According to the method, by applying a blockchain to the large-scale e-commerce application scene, the scalability needed by the large-scale e-commerce scene can be achieved, millions of nodes can be supported, the consensus requirement that the service speed of the e-commerce is ten millions per second can be met, energy consumption such as Bitcoins is not needed, and the problem that a blockchain adopting proof of stake (POS) is lack of security guarantee is solved. The method comprises the steps that 1, the structure of the blockchain is composed of an alliance chain environment in a firewall, a gateway environment in a non-military isolation area and a platform in the public Internet; 2, alliance chain members elect a few nodes with a high trust degree from a public environment to serve as first-stage consensus nodes; and 3, a first-stage consensus result is sent to a alliance chain, the alliance chain members perform secondary consensus through voting to ensure the accuracy of the consensus result from the public environment, and then the security requirement is met.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a credit-based block chain consensus method suitable for large-scale e-commerce. Background technique [0002] Blockchain technology is considered to be a disruptive technology for the next generation of the Internet, which solves the problem of high cost of establishing trust on the Internet. It is called the "Internet of Value". Applications. [0003] The existing blockchain consensus algorithms are mainly divided into two categories: public chain consensus algorithms and private chain consensus algorithms. Public chain consensus algorithms mainly include proof of work (POW), proof of stake (PoS) or representative proof of stake (DPoS). For example, the consensus mechanism of Bitcoin is PoW, while Peercoin and NXT adopt the PoS consensus mechanism, and Bitshares adopts the DPoS consensus mechanism. The disadvantage of the proof-of-work mechanism PoW is low efficiency an...

Problems solved by technology

[0005] The technical problem of the present invention is: to overcome the deficiencies of the existing technology, to provide a credit-based block chain consensus method suitable for large-scale e-commerce, which applies the block chain to large-scale e-commerce application scenarios, which can not only Reach the scalability needed for large-scale e-commerce scenarios, support millions of nodes, and meet the consensus requirements of tens of millions of e-commerce services per second. At the same time, it does not require energy consumption like Bitcoin, and avoids the use of POS proof of rights Mechanism security and fairness issues
