Digital currency transaction method and system based on block chain

Abstract

The invention belongs to the field of blockchain and digital currency payment, and relates to a blockchain DPoS consensus algorithm, in particular to a blockchain-based digital currency transaction method and system. The method comprises the following steps: registering each digital currency terminal into a blockchain network, initiating election by a long-term accounting node, determining a corresponding group coefficient by each terminal according to a benefit group to which the terminal belongs, calculating a right and interest value of the digital currency terminal, determining the numberof voted terminals, and electing a short-term accounting node; the digital currency terminal generates transaction information; in a short-term accounting period, the accounting node monitors transaction information in the block chain network in turn, executes accounting rights in turn after verifying the transaction information, packages the digital currency transaction information into blocks and broadcasts the blocks to the block chain network, and continues to elect a new short-term accounting node; the method is more suitable for the fields of finance, banks and the like; the digital currency based on the blockchain endows the currency payment system with higher security and high efficiency, and is helpful for privacy protection of users.

Description

technical field [0001] The invention belongs to the fields of block chain and digital currency payment, relates to a block chain DPoS consensus algorithm, and particularly relates to a block chain-based digital currency transaction method and system. Background technique [0002] According to McKinsey's calculations, from a global perspective, the application of blockchain technology in B2B cross-border payment and settlement business will help cross-border payment and settlement business transaction participants save about 40% of transaction costs, of which about 30% are transit 10% of the bank's payment network maintenance costs are compliance, error investigation and foreign exchange costs. The point-to-point payment method created by using digital currency and blockchain technology will save the intermediate links of third-party financial institutions, not only 24-hour real-time payment, real-time arrival, no hidden costs, but also help reduce cross-border e-commerce cap...

Problems solved by technology

[0006] Second, the current digital currency system tends to issue coins independently and completely out of supervision, which will make the money supply unstable. In addition, the authorities cannot monitor the issuance and circulation of digital currency, resulting in the inability to accurately judge the economic operation, and bring troubles to policy making. to bother, and at the same time weaken the effectiveness of policy transmission and implementation

[0007] Third, the current equity calculation method only protects the interests of stakeholders, but does not prevent the actual election power from falling into a dictatorial winning coalition formed by a very small number of wealthy nodes

[0009] The disadvantages of using the traditional currency system are the risk of refusal, fraud, complicated procedures, and high costs. In the digital currency based on the DPoS consensus algorithm, due to the attributes of the network nodes themselves and the hidden interest relationship between nodes, The problem of plutocratic rule and the imbalance of group interests caused by the formation of interest groups between nodes and voting for specific candidate terminals that meet the interests of the group
