How to Develop Smart Contracts

A smart contract (also called a chaincode, which is a critical element of blockchains) is a program written in GO or Node.js. A chaincode is installed on the network's peer nodes, instantiated on (bound to) a channel, and invoked by an application through a client SDK or REST proxy. When invoked, the chaincode initializes and manages the ledger's state.

Download an Oracle sample to develop your own chaincodeDownload a "hello world" template (zip package) to test your chain code against your OABCS developer's instance.
