Hedera Guardian
Guardian is an open-source platform on the Hedera network for building auditable digital MRV: it runs methodology policies, records every calculation and document with verifiable provenance, and tokenises the resulting environmental assets. Straatos uses it as the trust layer behind registry submission.
Hedera GuardianStraatos’s Ledger submission runs on Guardian for verifiable data provenance and calculation transparency (Hedera).
Inside Hedera Guardian
Guardian lets a methodology be expressed as a digital policy workflow, then captures the data, calculations and documents that flow through it with tamper-evident provenance recorded on the Hedera public ledger.
It supports tokenising verified environmental assets and exposing the full audit trail to registries and buyers, and it is used in digital-MRV work with Verra and Gold Standard.
It is open-source and managed on Hedera’s network rather than a single-vendor product.
How Straatos integrates Hedera Guardian
A core named Straatos integration: the trust/provenance layer beneath the Ledger submission module, distinct from the registries it submits to.
Verifiable submission
Straatos’s Ledger packages project data through Guardian so each submission carries auditable provenance ("your gateway to verifiable submission, powered by Guardian").
Provenance, not overclaim
Guardian provides the audit trail; the registry still performs validation, so positioning stays "verifiable", not "verified".
Registry bridge
Routes provenanced packages toward Verra and Gold Standard digital-MRV pathways.
