Problems solved by technology

[0003] However, at present, when the blockchain client communicates with blockchain nodes through the Grpc proxy, it only supports the forwarding of conventional Grpc requests. For Grpc requests in duplex stream mode, it is difficult to support the identity verification function; or generally requires The blockchain client implements forwarding by configuring the IP address, but in the blockchain scenario, users generally do not care about the IP of the node, and if the IP is still used, it will increase the difficulty for the user

Abstract

The embodiment of the invention is suitable for the technical field of block chains, and provides a data communication method and device for a block chain client, and the method comprises the steps: receiving a Grpc request from the block chain client; if the Grpc request comprises a request header, acquiring a node mark and an identity mark of the Grpc request from the request header; acquiring a data signature of the Grpc request from a request body of the Grpc request; performing identity verification on the Grpc request according to the data signature and the identity mark; if the Grpc request passes the identity verification, establishing a communication connection between the block chain client and a corresponding target block chain node according to the node mark; and forwarding the Grpc request to the target block chain node through the communication connection. Through the method, data communication between the block chain client and the block chain node can be realized by using the Grpc proxy.

Description

technical field [0001] The present application belongs to the technical field of block chain, and in particular relates to a data communication method and device of a block chain client. Background technique [0002] The blockchain client sends a request to the blockchain node to realize data interaction with the blockchain. The blockchain client can communicate with the blockchain nodes through the Grpc proxy. [0003] However, at present, when the blockchain client communicates with blockchain nodes through the Grpc proxy, it only supports the forwarding of conventional Grpc requests. For Grpc requests in duplex stream mode, it is difficult to support the identity verification function; or generally requires The blockchain client implements forwarding by configuring the IP address, but in the blockchain scenario, users generally do not care about the IP of the node, and if the IP is still used, it will increase the difficulty for the user.
