🕸️ LIBYS Protocol

Sovereign Reputation via Delegated Trust Graphs.

---

⚡ TL;DR

LIBYS turns interactions into a trust graph:

• identities = Ed25519 keypairs
• actions = signed events
• authority = expressed via delegation (no key sharing)
• reputation = derived from graph structure

Trust is not assigned. It is accumulated.

💡 Why this exists

Today:

• identity is cheap to recreate
• reputation is locked inside platforms
• trust is centralized and non-portable

The protocol separates:

• identity
• authority
• reputation

So trust can emerge without a central owner.

🧠 Core Model

At its simplest form:

(identity) --[signed event]--> (subject)

With delegation:

(identity A) --[system.auth.grant]--> (identity B)  
(identity B) --[delegated event]--> (subject)

• users can delegate authority to apps
• applications can delegate authority to users
• services can delegate to other services

There is no distinction between “user” and “application” at the protocol level.

🔍 Reputation Model (Out of Scope)

The protocol does not define how reputation is calculated. Reputation is derived by observers analyzing the trust graph according to their own criteria.

This may include:

• interaction history
• delegation chains
• graph connectivity
• cluster detection or filtering

LIBYS defines verifiable data, not subjective interpretation. Different observers may reach different conclusions from the same data.

🧩 Use Cases

Examples enabled by LIBYS:

• portable reputation: carry trust across platforms
• brokerless marketplaces: P2P trade based on history
• scoped DAO governance: delegated authority via system.auth.grant
• sybil-resistant social: structural cost for identity reset
• autonomous agent trust: secure M2M delegation

📦 Proof of Concept (PoC)

This repository includes a minimal Java implementation demonstrating:

• identity creation
• event signing
• delegation flow
• verification

Prerequisites

• Java 17+ & Maven
• jq and xxd (for the demo script)

Quick Start

To see the protocol in action, run the automated demo:

chmod +x poc/demo.sh
./poc/demo.sh

Manual Testing

You can interact with the CLI directly. Detailed examples of commands are available in poc/NOTES.md.
