Dovu IWA Policies

DOVU has leveraged the IWA VEM specification for the carbon token lifecycle by delivering an auditable process, focused on MRV and capturing proofs in the audit trail tied to individual actors that have been validated and verified. These actors have unique keys, which they use to sign every transaction following W3C Decentralized Identifier (DID), Verifiable Credential (VC), and Verifiable Presentation (VP) standards and linking them to a native Token using the Hedera Hashgraph public DLT and Hederaโ€™s Guardian, an open source reference implementation of the IWAโ€™s Voluntary Ecological Markets Standards.

Understanding Dovu's Process

The first step towards compliance was building a system to support manual attestations for an MRV. To mitigate the risk of manually attested data, DOVU supports attestation from multiple sources, as well as verification of the manual data by a 3rd party verifier. In addition, in order to reduce the risk of actors carrying the risk of manual data, DOVU is building a collateral mechanism that would be tied to these actors to serve for insurance purposes.
