Abstract

The invention provides an alliance chain multi-language external chain code offline compiling method and system, and the method specifically comprises the steps: responding to an external chain code offline compiling request, obtaining a chain code language definition in the request, selecting an external builder type of a chain code packet according to the chain code language definition, calling a detect component to select an external builder from the corresponding external builder type, enabling the external builder to build a chain code packet according to the request information; calling a build component to compile the chain code packet to obtain a chain code, and starting the chain code; verifying a certificate, a private key and a root CA certificate of the Peer node, and starting a TLS protocol between an external chain code server and the Peer after verification is passed; calling a release component to provide metadata, wherein the metadata comprises a CouchDB state database index definition and connection information of an external chain code service; connecting the Peer node with the external chain code server according to the connection information of the external chain code service in the metadata, and calling the created external chain code after the connection is completed.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method and system for off-line compiling of alliance chain multilingual external chain codes. Background technique [0002] In the consortium chain, the compilation and startup process of the chain code is part of the peer implementation, which is not easy to customize. All chaincodes installed on a peer are created using language-specific logic hard-coded in the peer. This process will generate a Docker container image that starts and executes the chain code as a client to connect to the peer. This method limits the implementation of chaincode to a few languages, cannot customize chaincode for specific languages, has poor adaptability and scalability, and prevents chaincode from being a long-running service. External builders and launchers address these limitations by allowing operators to extend peers with programs that can build, launch, and discover chaincode. Cont...
