Data sharing method and device, equipment and storage medium

The invention discloses a data sharing method and device, equipment and a storage medium, and relates to the technical field of block chains. The method is applied to all nodes of an alliance chain, the alliance chain further comprises a plurality of accounting nodes, and the method comprises the following steps: receiving a sharing request of a first accounting node for linked and encrypted target data; generating a target proposal for sharing the target data, and sending the target proposal to a second accounting node which uploads the target data, so that the second accounting node generates a voting result whether the target proposal is passed or not; and sending a private key for decrypting the target data to the first accounting node under the condition of receiving the voting resultwhich is generated by the second accounting node and passes the target proposal, so that the first accounting node shares the target data through the private key. According to the embodiment of the invention, the scale of sh
