Problems solved by technology

[0003] (1) The transaction confirmation time is long, the block generation speed is more than 10 minutes, and the transaction confirmation time is as long as one hour;
[0004] (2) There is a 51% attack vulnerability, that is, when the attacker has more than 51% of the computing power, he can maliciously change the blockchain information;
[0005] (3) Users need to download the entire blockchain information and act as miners for "mining", which wastes computing resources

Abstract

The invention relates to digital asset transactions in the internet and provides a decentralized transaction method. The method comprises the steps that a verification node obtains a to-be-verified transaction; a trusted node sends a proposal to the verification node, wherein the proposal contains all transactions regarded to should be contained in an account book by the trusted node; the verification node checks whether the received proposal is from a legal trusted node in a trusted node list or not, if yes, the proposal is stored, if not, the proposal is discarded, and finally an approved transaction list is determined according to a plurality of stored proposals; and if each transaction in the trusted node list obtains trusted node approvals with a number at least exceeding a set threshold, a final account book is generated and a consensus is reached for the account book. According to the method, the transaction confirmation verification time can be shortened and large amounts of computing resources are saved.

Description

technical field [0001] The invention relates to digital asset transactions on the Internet, in particular to a decentralized fast transaction verification and consensus method. Background technique [0002] Since the launch of the Bitcoin system in 2009, decentralized cryptocurrencies represented by Bitcoin and its derivative altcoins have received widespread attention. The distributed encrypted currency system represented by Bitcoin adopts the PoW (Proof of Work, commonly known as "mining") mechanism for transaction verification and consensus reaching, and there are the following problems: [0003] (1) The transaction confirmation time is long, the block generation speed is more than 10 minutes, and the transaction confirmation time is as long as one hour; [0004] (2) There is a 51% attack vulnerability, that is, when the attacker has more than 51% of the computing power, he can maliciously change the blockchain information; [0005] (3) Users need to download the entire...
