Block chain-based digital medical information storage and sharing architecture construction method

The invention relates to the technical field of medical data information data processing, in particular to a block chain-based digital medical information storage and sharing architecture construction method. The block chain-based digital medical information storage and sharing architecture construction method comprises the following steps of: mapping a plurality of users located at peer-to-peer nodes into a network of a block chain in a node mapping manner; the users at least comprise private doctors, hospitals, clinics, individuals and scientific research institutions; a coalition chain is formed among users in a network of block chains, and transaction signals can be sent to users on other nodes among the users among the nodes on the coalition chain, so that doctor-patient information data can be obtained among the users among the nodes on the coalition chain. Therefore, the transaction mode of the doctor-patient information A in the network of the block chain is free and equal, the non-tampering property
