Hyperledger Fabric Gateway Client API for Go

The Fabric Gateway client API allows applications to interact with a Hyperledger Fabric blockchain network. It implements the Fabric programming model, providing a simple API to submit transactions to a ledger or query the contents of a ledger with minimal code.

• fabric-samples/asset-transfer-basic for examples of transaction submit and evaluate.
• fabric-samples/asset-transfer-events for examples of chaincode eventing.
• fabric-samples/off_chain_data for examples of block eventing.
