Verified ContractDistributed Systems & Web3Full-Stack Applications

Transparent Supply Chain Platform

Decentralized product traceability platform designed to verify provenance and maintain immutable chain-of-custody across multi-tier supplier networks.

Project Overview

Global supply chains frequently suffer from counterfeiting, unauthorized substitutions, and opaque custody transitions. Centralized databases remain vulnerable to unauthorized tampering, necessitating a cryptographic, verifiable audit trail.

What It Does

A decentralized application that records product lifecycle milestones, quality inspections, and custody handoffs on an immutable ledger. Stakeholders and consumers can cryptographically verify product authenticity and provenance at every stage.

Key Capabilities

Immutable custody transfer logging on an Ethereum-compatible distributed ledger
Decentralized document and inspection certificate storage via IPFS
Smart contract-enforced milestone verification preventing retroactive tampering
Web interface for scanning product identities and viewing verified historical journeys
Cryptographic signature verification for authorized supplier and inspector accounts

Engineering Highlights

  • Authored Solidity smart contracts governing multi-party custody state transitions
  • Integrated InterPlanetary File System (IPFS) for tamper-evident decentralized document storage
  • Developed web frontend interfaces interacting with blockchain nodes via Web3 libraries
  • Implemented client-side transaction signing and wallet integration workflows
  • Tested contract state safety and event emissions across testnet environments
