Thallo’s Two-Way Carbon Bridge is a key feature for maintaining integrity in the voluntary carbon markets.
This “Two-Way Carbon Bridge” refers to how Thallo moves carbon credits onto the blockchain from an underlying registry. Specifically, it allows carbon credits to be moved on and off the blockchain while ensuring transparency and traceability to avoid double accounting.
Information about the project, vintage, serial numbers, and other details are stored on-chain in the Thallo bridge. This architecture allows anyone to query this data at any time due to the public and distributed nature of the blockchain – even if the registry system is unavailable.
The bridge enables credit retirements to be performed on-chain while also being reflected on the underlying registry. As a result, the bridge is additive to the existing ecosystem and allows retirees to benefit from the highly credible retirement certificates already being issued by registries, as well as the Proof-of-Retirement NFT for immutable on-chain certification.
