Project description:
"Project Overview
We are building a private, tamper-evident event ledger for a distributed system.
The ledger will record lifecycle events, versioned assets, verification records, configuration changes, and security-relevant markers across multiple organizational domains.

We are looking for a senior Hyperledger Fabric engineer to architect, deploy, and customise a Fabric network, and to implement the core chaincode modules for this audit and integrity layer.

This is a foundational project and will serve as the backbone for a larger platform.

Scope of Work

1. Fabric Network Architecture & Deployment

Set up a minimal but production-ready Hyperledger Fabric environment with:

Multi-organization structure (starting with 2 orgs)

Certificate authorities and membership service providers (MSPs)

Raft ordering service

Channel creation and policy configuration

Docker/Kubernetes-based deployment

Fully reproducible setup scripts/configs

2. Custom Chaincode Development

Develop chaincode modules to represent and manage append-only records such as:

Asset or component registration

Versioned items (e.g., firmware, documents, or other controlled assets)

Verification or calibration events

Configuration profiles

Configuration activation/deactivation events

Security or incident markers

Requirements:

Strong input validation

Immutable, event-based design

Linkages between related records

Query functions (by ID, by time range, by type)

Basic test coverage

3. Integration Support

Provide reference examples demonstrating how an external service can:

Submit events

Query historical records

Retrieve audit trails

Validate identities or signatures

(Full backend implementation is not required — just clear integration guidance.)

4. Documentation & Handover

Network architecture document

Chaincode documentation

Setup + deployment guide

Handover call for walk-through and Q&A

Ideal Candidate

Proven experience deploying Hyperledger Fabric networks

Skilled with Fabric CA, MSPs, peers, ordering services, channels

Strong chaincode development background (Go or NodeJS)

Experience designing event-driven or audit-oriented data models

Able to work independently and communicate architectural decisions clearly

Deliverables

Fully functional multi-org Fabric network (dev-ready)

Core chaincode modules implemented and tested

Example invoke/query scripts

Documentation + training session

Timeline

Estimated 2–4 weeks, depending on complexity and availability." (client-provided description)
