Evidence Chain

Evidence Graph (EDG)

Cryptographic audit trail for all AI operations

Overview

What is EDG?

The Evidence Graph is ETHRAEON's cryptographic audit system. Every AI operation in the Tracelet framework emits an EDG node. a SHA-256 hashed record of the agent, task, result, and timestamp.

EDG provides irrefutable proof that AI operations occurred exactly as recorded, enabling regulatory compliance, dispute resolution, and public verification.

Structure

EDG Node Format

Each EDG node contains:

{
  "agent": "ARCANUM",
  "task": { "type": "emit_block", "content": "..." },
  "result": { "status": "success", "block_id": "ARK-001" },
  "timestamp": "2026-01-15T10:30:00Z",
  "tracelet_version": "1.1.0"
}

The SHA-256 hash is computed from the canonical JSON (sorted keys).
