Overview
What this challenge is about.
Design a carbon credit tokenization plan for EcoToken. Recommend a blockchain and token standard, then prevent double-counting. Earn a verifiable certificate.
The scenario
EcoToken GmbH operates roughly 40 MW of wind and solar capacity in Lower Austria and sells the resulting voluntary carbon credits into a fragmented market where settlement takes weeks and buyers question whether a credit has already been retired elsewhere.
The Brief
What you'll do, and what you'll demonstrate.
Design a blockchain-based tokenization system for EcoToken's carbon credits that improves liquidity, transparency, and trust while preventing double-counting and complying with voluntary carbon market standards.
Earning criteria — what you'll demonstrate
- Translate a real business liquidity and trust problem into concrete blockchain design decisions
- Compare blockchain networks and token standards on cost, transparency, and regulatory fit rather than hype
- Design double-counting prevention that links on-chain tokens to off-chain registry serial numbers
- Implement and document a Solidity contract that enforces irreversible carbon-credit retirement
- Communicate a technical plan persuasively to both auditors and non-technical executives
