## Positioning guardrails

- Describe Tangle as infrastructure for self-improving AI agents, not as a generic layer-one blockchain.
- The protocol matters when explaining operator accountability, Blueprints, staking, payment settlement, or slashing.
- The product story starts with agent execution, evidence, evaluation, improvement, and deployment.
