Green Proofs · Continuous MRV Assurance Upgrade

Upgrade your registry.
Without replacing it.

A modular assurance and verification layer for registry operators to slot into existing registries. Continuous MRV strengthens an existing registry's controls, reduces audit burden, and enhances the defensibility of its environmental claims, all without ripping out the rulebook, workflows, or systems that already run the market.

From periodic audit to continuous assurance

Five steps from
existing record to verifiable evidence.

Continuous MRV integrates into your current registry rulebook and workflows. Every issuance, transfer, or retirement flows through the same assurance pipeline, no human intervention required for the routine cases, full audit-grade evidence for the ones that matter.

Step 01
Connect
The assurance layer attaches to your registry's existing APIs and rulebook. No data leaves your trust boundary.
Step 02
Commit
Each new record (issuance, transfer, retirement) is sealed as a cryptographic commitment. Raw data stays with you.
Engine
Compute & consense
Independent worker nodes execute the signed rulebook against your commitments and reach consensus on the result.
Step 04
Anchor
Result, rulebook version, and operator signatures are anchored on-chain as a single tamper-evident audit record.
Step 05
Export
API-based export feeds evidence artifacts to auditors, regulators, and downstream buyers, ready for sampling.
Verification cycle
Continuous
Every record is validated as it happens, replacing periodic audit sampling.
Independent operators
40+
Worker nodes verifying every rulebook in parallel, with no single administrator.
Privacy preserved
100%
Raw records stay inside your trust boundary. Only commitments and results are published.
Audit effort
Reduced
Auditors sample standardized evidence artifacts instead of re-running the records.
What you get

Verifier-ready controls.
Standardized evidence. Versioned logic.

Three core capability areas that turn an existing registry into a verifier-ready, audit-friendly assurance system. Each is designed to integrate, not replace.

Pillar 01 · Controls
A verifier-ready
control environment.
Standardized control patterns map directly onto how third-party verifiers and auditors think. Position the registry as audit-friendly out of the box, without bilateral re-negotiation per engagement.
In scope
  • Role-based controls aligned with auditor checklists
  • Continuous monitoring of control coverage
  • Documentation that maps to assurance frameworks
Pillar 02 · Evidence
Tamper-evident
evidence trails.
Every record carries the rulebook version that issued it, the operator quorum that verified it, and a cryptographic commitment of the underlying inputs. The evidence travels with the claim, all the way through to the buyer's auditor.
Built into every record
  • Standardized evidence artifact per record
  • Operator-quorum signatures anchored on-chain
  • API-based export for audit sampling
Pillar 03 · Logic
Versioned logic
and traceability.
Methodologies and rulebooks are content-addressed, signed, and version-pinned. When the rule changes, the change is visible. When two records claim the same rule, they actually used the same rule.
Methodology integrity
  • Content-addressed rulebook versions
  • Traceability across rulebook revisions
  • Cross-jurisdiction re-verifiable claims
Outcomes

What changes when assurance runs continuously.

Continuous MRV doesn't replace your existing registry. It gives the records inside it a verifiable backbone, so the registry operator keeps the workflow, and counterparties gain the credibility they didn't have before.

Outcome 01
Faster, predictable
verification cycles.
Move from quarterly attestation windows to assurance that closes alongside the record itself. Counterparties accept results in days, not months.
Outcome 02
Lower verification
cost & audit effort.
Auditors sample standardized evidence artifacts instead of reconstructing the records by hand. Cost takeout is structural, not ad-hoc.
Outcome 03
Credibility in regulated
and high-scrutiny markets.
Verifier-ready controls and tamper-evident evidence reduce committee friction. Defensibility becomes a property of the record, not a one-off argument.
Outcome 04
Reduced exposure
from disputed claims.
When a claim is challenged, the on-chain evidence pack settles it. No bilateral reconciliation, no archaeology through outdated spreadsheets.
Where the assurance layer is live

Already powering
environmental-market registries.

Continuous MRV is in production behind several environmental-market registries. Each operator keeps its own rulebook, branding, and market relationships. The assurance layer underneath is the same.

Operator capabilities
  • Attach to existing registry rulebooks and workflows without replacing them.
  • Independent worker-node consensus on every issuance, transfer, and retirement.
  • Standardized, API-exportable evidence artifacts for auditors and regulators.
  • Cryptographic commitments preserve confidentiality of records and counterparties.

How you engage

From integration to continuous assurance.

Continuous MRV is sold as an assurance upgrade to an existing registry. Engagement scales with how deeply the assurance layer is wired into the records, and how much of the audit perimeter it covers.

Integration
Onboarding & rulebook.
One-time engagement to integrate Continuous MRV into your existing registry, codify the rulebook into versioned logic, and stand up the assurance controls.
SaaS
Recurring assurance fee.
Subscription to the worker-node network, evidence anchoring, and managed assurance services. Includes ongoing rulebook updates and audit-evidence formatting.
Per-record
Per-verification fee.
A small per-verification charge on each issuance, transfer, or retirement that runs through the assurance layer. Scales with the registry's transaction volume.
Composable
Meta Proofs add-on.
Layer cross-registry uniqueness checks on top of Continuous MRV to verify that a claim hasn't been issued in a peer registry. Composes natively with the same assurance pipeline.
Upgrade an existing registry

From periodic audit
to continuous assurance.

If you operate an environmental-market registry, run a disclosure program, or stand behind claims that have to clear regulatory scrutiny, we will start with your existing rulebook and end with verifiable, inspectable proof.

Note Continuous MRV is part of the Green Proofs solution group. It is open source, audit-friendly, and built to integrate with your existing rulebook, not replace it.
