ARCANUM

What is ARCANUM?

ARCANUM is ETHRAEON's cryptographic intelligence agent, responsible for EDG (Evidence Graph) emission, hash verification, and constitutional compliance validation. It provides the cryptographic foundation that makes all AI operations auditable and verifiable.

Every state-changing operation in the Tracelet framework emits an ARCANUM-verified evidence node, creating an immutable audit trail.

Evidence Graph System

ARCANUM manages the Evidence Graph — a cryptographic chain linking all AI operations:

{
  "agent": "TELL_ME",
  "task": { "type": "query", "payload": "..." },
  "result": { "status": "success", "data": "..." },
  "timestamp": "2026-01-25T19:30:00Z",
  "tracelet_version": "1.1.0",
  "edg_hash": "sha256:abc123..."
}

Each node contains the agent, task, result, timestamp, and a SHA-256 hash of the canonical payload.

Core Functions

• EDG Node Emission: Generate cryptographic evidence for all operations
• Hash Verification: Validate evidence node integrity
• Chain Validation: Verify complete evidence chains
• Constitutional Audit: Prove compliance with governance rules
• Public Hash Lookup: Allow external verification of evidence
• Tamper Detection: Identify any modifications to stored evidence

Tracelet Architecture

ARCANUM provides cryptographic services to all Tracelet agents:

• TELL_ME: Research operation evidence
• BLOOM: Creative synthesis verification
• FOUNDER: Strategic decision audit
• KAIROS: Temporal governance timestamps
• CCT: Compliance decision records
• CT_MIRROR: Transparency chain linkage

Public Audit Interface

Anyone can verify an EDG hash at:

https://edg.ethraeon.ai/verify/{hash}

Returns the full evidence node if the hash is valid, or 404 if not found.
