A blockchain based platform to provide a central directory of voluntary offsets based on a decentralized architecture. The decentralized permissioned architecture allows recognized participants around the world and in different functional roles (developers, brokers, buyers, verification bureaus, standards organizations) to contribute data about voluntary carbon offsets. Built on a permissioned network such as Hyperledger Fabric, members Members of the network could contribute data about voluntary carbon offsets, including the projects details, quantity issued, background documentation, and any trades that occur. Fabric is a high speed ledger, faster and with lower energy usage than public proof of work or even proof of stake ledgers. We could use IPFS or another decentralized storage mechanism to store documentation of the offsets and use md5 to verify that documents have not been altered.
The solution would be an open source code base which includes Fabric chain codesmart contracts, scripts to access the network, plus a basic web UI for demonstration purposes. Initially the data could come from the Berkeley Carbon Trading Project of different offsets registries, so the schema would be based on their data as well. A proposed governance and incentive structure:
