Arcform — Sovereign Verification Skill

About

Arcform — Sovereign Verification Skill

A developer-grade browser companion for the Arcform DID.comms API. Verify decentralised identity envelopes, generate cryptographic proof checksums, and monitor live governance alerts — all from your browser toolbar.

Built for developers building on sovereign identity infrastructure. Zero data collection. Zero external dependencies. Under 60KB.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🔐 WHAT IT DOES

• Verify envelope integrity against the Arcform ledger in one click • Generate SHA-256 proof checksums using the canonical wire format — byte-identical to the server-side implementation • Monitor real-time governance and audit alerts from the Arcform control plane • Maintain a local, tamper-evident audit trail of every verification performed (IndexedDB) • Participate in Portal-to-Portal mesh consensus for cross-node validation

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

⚡ KEY FEATURES

4-Zone Panel Identity status, usage metrics, zero-knowledge hashing, and control plane alerts in a single 380px popup.

Local-First Hashing All cryptographic operations run in-browser via the Web Crypto API (crypto.subtle). No data leaves your machine.

Offline Audit Spine Every verification verdict is recorded locally in IndexedDB. Query, export, or clear your audit trail at any time.

Live Alert Feed Polls the Arcform API every 60 seconds for governance events, degraded verdicts, and ledger status changes. Critical alerts trigger native Chrome notifications.

Attestation HUD Content script scans web pages for Arcform envelope hashes and injects real-time verification badges directly into the DOM.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🛡️ PRIVACY & SECURITY

• Zero data collection — no telemetry, no analytics, no tracking pixels • All hashing is local-only. Raw input is never transmitted or stored • IndexedDB audit data stays on your device — never synced to any server • Zero external dependencies — under 60KB total extension size • Open source. Every line of code is inspectable on the extension page

🏗️ WHY INSTALL THIS?

If you're building on decentralised identity — DIDComm, Verifiable Credentials, or sovereign messaging — you need a way to verify what's happening at the transport layer without trusting the server. This extension gives you that.

Every hash is computed locally. Every verification is recorded in a tamper-evident audit spine on your device. The Arcform API never sees your raw data — it only receives the checksum for comparison.

Whether you're a developer integrating Arcform into a fintech platform, a compliance team auditing message delivery, or a researcher exploring decentralised identity protocols, this extension puts verification in the browser where it belongs.
