The invention relates to the technical field of block chains, in particular to a block chain data transmission method, device and equipment and a readable storage medium, and the method comprises the steps: responding to a data transmission request sent by a client, and calling corresponding first to-be-transmitted data according to the data transmission request; encrypting the first to-be-transmitted data to obtain first encrypted data; sending the first encrypted data to a data receiving node; two characteristics in a block chain network are utilized, the first characteristic is that the block chain node has a specific data receiving interface which is always in an open state, so that a transmission interface does not need to be reserved in advance, and the second characteristic is that the block chain node has public keys of all other nodes, so that the public key of the opposite side does not need to be requested, and the transmission efficiency is improved. According to the invention, when the encrypted
