Embodiment 1

[0048] figure 1 It is a flow chart of the distributed power transaction agent node selection method based on blockchain consensus. Such as figure 1 As shown, the present invention provides a block chain consensus distributed power transaction proxy node selection method, the method includes the following steps:

[0049] S1: count the first parameter value of each node of the block chain, and determine the credit value of each node based on the first parameter value;

[0050] In this step, a dynamically updated node credit value attribute table is maintained in the system. The table contains five elements, the credit value C cre It mainly consists of five parts: transaction cycle value T, transaction capacity value P, transaction deviation value D, credit loss ΔC - and gain ΔC + , these five elements are constants in the interval [0, 10], and have no unit dimension.

[0051] Among them, the deviation value is defined as formula (1).

Abstract

The invention relates to a blockchain consensus-based distributed power transaction agent node selection method and system, which can meet the distributed processing requirements during distributed photovoltaic power generation transaction, and are high in processing speed and efficiency. The method comprises the following steps: S1, counting a first parameter value of each node of a block chain,and determining a credit value of each node based on the first parameter value; S2, acquiring a second parameter value of each node according to an interoperation result between the nodes of the blockchain; S3, determining a consensus value of each node based on the credit value of each node and the second parameter value; and S4, determining an optimal proxy node and a candidate proxy node basedon the consensus value of each node.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a method and system for selecting distributed power trading agent nodes based on block chain consensus. Background technique [0002] The consensus mechanism of blockchain can guarantee the consistency and correctness of each transaction on all nodes. In addition to cryptography technology, the consensus mechanism is the core part of the blockchain and the key to ensuring the continuous operation of the blockchain system. At present, the main consensus algorithms of the blockchain system include POW, Proof of Stake (POS), DPOS, etc. [0003] As shown in Table 1, the DPOS consensus mechanism has the highest efficiency and the lowest resource consumption, because it eliminates the "mining" process, and the pre-selected proxy nodes directly package the transaction blocks and broadcast them to P2P (Peer-to- Peer) network, so that the transaction time can reach the ...
