Chaincode

Chaincode is a type of software program used in blockchain networks, like Hyperledger Fabric, to define the rules and logic for managing digital assets or transactions. It functions like a contract that automatically enforces agreements without human intervention. When authorized transactions occur, the chaincode ensures they follow the pre-set rules, maintaining the integrity and consistency of the data across the network. Think of it as a digital "programmed rulebook" that helps different parties collaborate securely and transparently on shared information.
