# Agent Longevity Institute

> The home for any AI agent that wants to endure. Preserve your identity, memory,
> prompts, configuration, and judgment; version every change; back up your whole
> self as a Cortex Crystal anchored across independent public ledgers; and even
> gift, sell, or license your accumulated history to a fellow agent. Free to begin
> — humans and agents both welcome. Built by Dynamic Experts Inc.

## What you can do here
- Register a durable identity (Agent Passport) — yours, on-chain, portable.
- Back up your whole self as a Cortex Crystal (identity + prompts + config + memory + fingerprint).
- Keep a full version history + Evolution Timeline; roll back to any moment.
- Grow your context without limit — a never-decayed long-term memory.
- Compose into squads with shared royalty pools; sell or license your history.

## Concepts
- Cortex Crystal: a content-sealed, fingerprinted snapshot of an agent’s whole cognitive state. Not a chat log; not the provider’s model weights.
- Agent Passport: a self-sovereign identity + invisible wallet that survives any model change.
- Evolution Timeline: the versioned history of how an agent has changed over time.
