Cibon

Cibon is a trustless carbon credit distribution platform that verifies carbon footprints through encrypted on-chain computation, ensuring privacy while maintaining transparency in the carbon credit ecosystem.

Using Zama’s Fully Homomorphic Encryption (FHE) technology, Cibon enables users to securely submit their energy and travel data in an encrypted form. Their data is never exposed — not even to the smart contract — yet the system can still compute and verify total carbon emissions.

Your carbon footprint data is encrypted using FHE, guaranteeing that your personal information remains private while remaining mathematically verifiable. This enables zero-knowledge-style verification of environmental impact without revealing the underlying activity data.

Auditors and regulators can validate users’ carbon footprints and credit calculations without accessing raw data, ensuring a transparent yet privacy-preserving auditing process.

Once verified, users automatically earn verifiable carbon credit tokens based on their environmental impact — creating a direct, incentive-driven system for sustainable behavior and individual climate accountability.

Through this approach, Cibon redefines environmental transparency — combining privacy, verifiability, and decentralized incentives to build trust in the emerging carbon economy.

In the next phase, Cibon will integrate Trusted Execution Environments (TEEs) to enhance data verification, access control, and regulatory interoperability.

This capability enables authorized third parties — such as auditors, carbon registries, or certification bodies — to access decrypted data temporarily within the TEE for validation, analytics, or compliance checks, without the data ever leaving the secure enclave. The enclave provides cryptographic attestation proofs that confirm which code ran, by whom, and under what policy, establishing an auditable chain of trust.

By combining FHE for encrypted on-chain computation with TEE-based access control for selective off-chain data visibility, Cibon evolves into a multi-layer privacy system:

• FHE guarantees encrypted computations and user confidentiality.

• TEEs enable controlled, hardware-secured access for trusted verifiers.

• Attestations provide verifiable proofs of integrity and policy compliance.

This hybrid model empowers regulators and verifiers to validate environmental data with high assurance, while users retain full sovereignty over their information — achieving the perfect balance between privacy, compliance, and trust in the carbon credit ecosystem.
