The present invention discloses a multi-block output public chain consensus mechanism based on H-Algorand. Firstly, a multi-block output public chain consensus mechanism MB-Algorand is proposed. The leader of this mechanism can continuously produce blocks, thereby effectively improving Secondly, in the scenario where the public chain committee is attacked by DDOS, the H-Algorand mechanism that combines the advantages of Algorand and MB-Algorand is proposed. This mechanism takes into account the performance of both consensus efficiency and security. A simulation comparison between the ‑Algorand mechanism and the Algorand mechanism shows that the H‑Algorand mechanism can effectively improve consensus efficiency at the expense of a small amount of security under the condition that the success rate of malicious attacks is 1% to 4%.
