📘 Chaincode Files Overview

This directory includes three Go-based chaincode files developed for a Hyperledger Fabric network, facilitating interactions within a Digital Twin and asset trading ecosystem.

🔹 Files Description

createPromise.go

• Defines the creation logic for promissory notes between a buyer and a seller.
• Used to generate and store agreement terms regarding asset usage and monetization.

promiseAndClaim.go

• A merged smart contract handling full lifecycle operations:
  • Creating and signing promissory notes,
  • Registering and claiming devices,
  • Managing payment distribution based on agreement terms.

registerAsset.go

• Provides foundational asset and device registration capabilities.
• Includes support for registering agents, devices, device models, and data batches on the ledger.

Each file implements contractapi.Contract and operates on Fabric’s world state. These contracts are key building blocks of the Digital Twin monetization network.
