The legal and technical skills required to convert centuries of legal language into programming Fabric chaincode lifecycle What is Chaincode? Chaincode is a program, written in Go [https://golang.org], Node.js [https://nodejs.org], or Java [https://java.com/en/] that implements a prescribed interface can see an example of a metadata file below: {"Path":"fabric- samples/chaincode/fabcar/go","Type":"golang","Label":"fabcarv1"} The chaincode is packaged separately by Org1 and Org2. Both organizations use
