Multi-block output public chain consensus mechanism based on H-Algand

Abstract

The invention discloses a multi-block output public chain consensus mechanism based on H-Algand. A mechanism firstly proposes a multi-block output public chain consensus mechanism MB-Algand, and a leader of the mechanism can achieve continuous block output, thereby effectively improving block output efficiency. Secondly, a public chain committee is attacked by DDOS;. An H-Algand mechanism integrating the advantages of Algand and MB-Algand is provided, so that an H-Algand mechanism integrating the advantages of Algand and MB-Algand is provided; the mechanism gives consideration to the performances of consensus efficiency and safety. Simulation comparison is carried out on an H-Algand mechanism and an Algand mechanism, and it is found that the consensus efficiency of the H-Algand mechanism can be effectively improved at the cost of sacrificing a small amount of security under the condition that the success rate of malicious attacks is 1%-4%.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an H-Algorand-based multi-block output public chain consensus mechanism. Background technique [0002] The Algorand mechanism was proposed by Professor SilvioMicali, and the algorithm was later implemented by Yossi Gilad, SilvioMicali and others. The verifiable random functions (VRFs) lottery algorithm used in it enables each node to have the opportunity to participate in the consensus, which improves the scalability of the consensus. The Byzantine Agreement (BA★) used in it makes the nodes only do binary consensus between the current block and the blank block, so that the chain bifurcation probability is only 10-18, even in areas with strong malicious nodes It can still maintain good performance in the block chain network environment. The 2Mbyte block uses the Algorand mechanism in a blockchain network of 50,000 users from proposal to completion of consensus in o...

Problems solved by technology

[0003] However, the public chain allows any member to join. With the large-scale promotion of the blockchain network in the future, the frequency and amount of network data interaction will increase, and it may show a certain periodicity

If the Algorand mechanism is used in large-scale transaction systems such as banks, transaction delays will accumulate and explode, causing the banking system to be paralyzed, and the consensus efficiency of the Algorand mechanism still needs to be improved
