description | The invention discloses a cold chain joint node data sharing method and device based on double chains of a block chain, and the device comprises a monitoring alliance chain and an evidence storage alliance chain, the monitoring alliance chain stores the public transaction data of the cold chain joint node, and the evidence storage alliance chain stores the private data of the cold chain node. The cold chain joint node is formed by combining cold chain independent nodes through an RBAC model, internal nodes of the joint node share the same authority for shared data, and an uplink request is put forward after transaction data is authenticated and signed. The open transaction data plaintext can be uploaded to the open alliance chain, and the monitoring alliance chain is open and transparent to all nodes. Private transaction data is uploaded to the authorized alliance chain after being symmetrically encrypted, and the evidence storage alliance chain is open and transparent to the authorized nodes.
