# Thallo Two-Way Carbon Bridge - Litepaper ## Abstract Thallo's Two-Way Carbon Bridge allows carbon credits to be moved on and off the blockchain while ensuring transparency and traceability to avoid double accounting and preserving the integrity of the credit. Information about the project, vintage, serial numbers etc are stored on-chain in the Thallo Bridge. This 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 whilst 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
