Pillars of AgentDNA

AgentDNA is built on the following pillars:

1. Chain of Custody Authentication (CoCA)​

Chain of Custody Authentication (CoCA) captures every interaction between participants as a cryptographically signed Envelope.

Rather than treating a workflow as a collection of independent events, every new Envelope wraps the previous one, forming a nested chain that preserves the complete journey of an intent.

Every participant signs only the action they performed, creating a verifiable chain of custody from the original requester to the final outcome.

2. Context Based Access Control (CBAC)​

CBAC evaluates the complete intent, verifies every signed participant in the chain and validates that the Agent's current policy permits the requested action. It does so by using a local Inference Engine that examines Agent's policy and with its intent, the initial user intent and calculates a Trust score for the Agent. Authorization changes from are you allowed? to are you allowed, and what is the intent?

3. Immutable Provenance​

Every completed workflow can be committed to the Provenance Layer as an immutable provenance record.

This provides:

  • Complete workflow history
  • Cryptographic proof of every participant
  • Auditability of every autonomous decision
  • Tamper-evident workflow storage
