Verify Authenticity and Ownership
About
The problem it solves # ERI: Authenticity & Ownership Verification on Base ## The Problem: COUNTERFEITING AND TRUST Counterfeiting is a **global crisis**, costing industries like electronics, fashion, and pharmaceuticals **$2.3 trillion annually**. Consumers and manufacturers face significant challenges due to the lack of transparent, tamper-proof systems to verify product authenticity and ownership. - **Consumers** often purchase high-value or critical products, such as pharmaceuticals, relying solely on the seller's credibility, with no reliable way to confirm authenticity. - **Manufacturers** are vulnerable to retailers introducing counterfeit goods into the supply chain, eroding trust and brand integrity. - **Ownership verification** is cumbersome, often requiring physical receipts that can be lost or forged. Without a robust solution, proving ownership demands excessive effort and often remains unresolved, leaving both consumers and businesses exposed. - **Existing solutions** like barcodes and RFID are centralized, susceptible to fraud, and fail to provide ownership tracking. In Africa, counterfeit goods constitute **13.6% of imports**, undermining consumer trust, stifling economic growth, and posing significant risks to safety and brand reputation. --- ## Our Solution: ERI We’re building a **decentralized platform on Base** that enables anyone to verify the authenticity and ownership of physical and digital products — **cryptographically, transparently, and trustlessly.** - **Manufacturers** issue and sign **EIP-712-based digital certificates** for each product. - These certificates are embedded into the product via **QR codes.** - **Consumers** can scan a product’s QR code to verify: - That the certificate is genuinely signed by the manufacturer. - That the product has not been claimed or duplicated. - Once verified, the consumer can **claim ownership on-chain** — creating an immutable, user-owned proof of possession. The entire process is powered by **Base’s infrastructure**, ensuring scalability, affordability, and strong privacy guarantees. ### Core Features: - Intuitive, Web3-native frontend for manufacturers and users. - **QR code generation** for product-level authenticity. - **On-chain ownership registry** — enabling transfer, resale, and post-sale services. - **Cross-device UX** with fast, wallet-integrated interactions. This system **removes trust from the equation** — replacing it with math, cryptography, and open verification. - For consumers: **it's peace of mind.** - For manufacturers: **it's brand protection at scale.** --- ## Market Opportunity The need for product authenticity and ownership verification is growing **exponentially** — driven by global losses to counterfeiting, rising consumer demand for transparency, and the digital transformation of supply chains. ### Global Opportunity: The **anti-counterfeiting market** is projected to exceed **$5 trillion by 2030** (Research and Markets), as governments, brands, and consumers demand secure verification systems. ### African Focus: Africa is disproportionately affected by counterfeiting — with **13.6% of imports being fake.** - Nigeria, Kenya, and South Africa are key hotspots, especially in **consumer electronics** and **pharmaceuticals.** - There’s a massive unmet need for tamper-proof verification tools across these regions. ### High-Impact Vertical Focus: - **Electronics** – Smartphones, accessories, and consumer gadgets often targeted by counterfeiters. - **Pharmaceuticals** – Life-saving drugs are frequently counterfeited, leading to health crises and eroded trust. - **Luxury Goods** – High-margin items (watches, fashion, etc.) demand provenance and proof of authenticity. ### Target Users: - **Manufacturers** – Protect their brand and prove authenticity at scale. - **Retailers** – Build trust and avoid reputational damage. - **Consumers** – Confirm they’re getting what they paid for and prove ownership when needed. --- ## Conclusion This is not a **niche problem** — it’s a **global trust crisis**, and ERI provides the **cryptographic infrastructure to solve it**. Built on **Base**, ERI delivers: - Transparent authenticity verification. - Immutable proof of ownership. - A scalable and secure foundation for future supply chains. **ERI is the future of authenticity and ownership.** --- ## PROJECT INFO. ## Project GitHub Repo: - https://github.com/eri-repo/ERI-Contract ## Contract Addresses: - Ownership Contract: 0x4500c12bfE76fC6C350c3021B5dcAD532fd1D211 -- https://sepolia.basescan.org/address/0x4500c12bfE76fC6C350c3021B5dcAD532fd1D211#code - Authenticity Contract: 0x3720f8B79B5E504E511EcEFb505b7f29ffCE73f5 -- https://sepolia.basescan.org/address/0x3720f8B79B5E504E511EcEFb505b7f29ffCE73f5#code Smart Contract Address(es) ## Contract Addresses: - Ownership Contract: 0x4500c12bfE76fC6C350c3021B5dcAD532fd1D211 -- https://sepolia.basescan.org/address/0x4500c12bfE76fC6C350c3021B5dcAD532fd1D211#code - Authenticity Contract: 0x3720f8B79B5E504E511EcEFb505b7f29ffCE73f5 -- https://sepolia.basescan.org/address/0x3720f8B79B5E504E511EcEFb505b7f29ffCE73f5#code
How it's made
Challenges we ran into ## Challenges and Lessons Learned We encountered several challenges during development, but two stood out the most. 1. **EIP-712 Implementation** Implementing EIP-712 was one of the toughest parts. Getting signatures generated off-chain and verified on-chain proved tricky, but we eventually solved it. 2. **On-Chain Architecture** In this version, we aimed to maximize decentralization by storing large amounts of information directly on-chain—essentially treating the blockchain as the database. While this created performance and architectural headaches, we managed to overcome them. --- ## What’s Next - **Improved Performance**: The next version will be faster and more cost-efficient. - **Base Name Integration**: We plan to integrate Base Name for better usability and identity management.
