Which programming model is used to develop easy-to-use smart contracts in Hyperledger Fabric?

The programming model used to develop easy-to-use smart contracts in Hyperledger Fabric is known as Chaincode. Chaincode refers to the specific smart contract implementation in the Hyperledger Fabric environment, where developers can write business logic in general-purpose programming languages like Go, Java, or JavaScript.

This flexibility allows developers to create modular and reusable code that interacts with the blockchain while executing the necessary operations in response to transactions. Chaincode runs in a secure environment on peers, ensuring that it operates as intended within the context of the blockchain network.

Oracles, protocols, and modules do not directly pertain to the development of smart contracts within Hyperledger Fabric. Oracles are external data sources that provide information to smart contracts but are not the contracts themselves. Protocols generally refer to the rules governing how data is transmitted across the blockchain. Modules can describe components or functionalities in programming but do not specifically address the contract development aspect within Hyperledger Fabric.
