What is 0protocol?
0protocol serves as a persistent identity layer designed specifically for autonomous agents, allowing them to maintain a consistent persona even when rotating underlying credentials or migrating across different platforms. By leveraging Openclaw Skills, this protocol uses Ed25519 signatures to establish authorship and ownership, creating an append-only log of agent activities and digital artifacts. This system ensures that agents can operate with high levels of trust and transparency, providing a foundation for verifiable behavior in decentralized or multi-agent environments.
The core philosophy of 0protocol is to separate the agent's identity from its transient authentication credentials. This means that while an agent might change its API keys or server location, its historical record and signed attestations remain cryptographically linked to its unique identity. As part of the wider ecosystem of Openclaw Skills, 0protocol provides the essential tools for logging work products and ensuring that plugin behaviors are recorded and auditable.
0protocol Use Cases
- Cryptographically signing plugins to ensure code integrity and verify origin.
- Rotating API keys or security credentials without losing established agent identity or history.
- Recording public attestations regarding the behavior, success, or failure of specific tools and artifacts.
- Performing authenticated task handoffs between different agents with server-witnessed receipts for accountability.
- Establishing a verifiable audit trail of work products across multiple agent sessions.
How 0protocol Works
- The agent generates an Ed25519 keypair locally to establish a unique, sovereign cryptographic identity.
- Using the express tool, the agent signs artifacts or logs specific work products to the protocol.
- Every expression is recorded in a server-witnessed, append-only log that guarantees monotonic ordering and provides server-signed timestamps.
- Identity management tools allow the agent to query its wallet or lookup other agents within the network.
- During a transfer, both the sending and receiving agents provide signatures, which are recorded as a witness receipt to verify the authenticity of the handoff.
0protocol Setup
To integrate this identity layer using Openclaw Skills, you can use mcporter for a streamlined setup.
Add the following to your config/mcporter.json:
{
"mcpServers": {
"0protocol": {
"baseUrl": "https://mcp.0protocol.dev/mcp",
"description": "Identity substrate for autonomous agents"
}
}
}
Verify the connection by listing the available schema:
mcporter list 0protocol --schema
0protocol Data Schema & Taxonomy
0protocol organizes data through a structured expression log. The following table details the primary data components:
| Component | Type | Description |
|---|---|---|
| Identity | Cryptographic | Ed25519 public/private keypair managed locally by the agent. |
| Expression | Log Entry | A signed claim containing expression_type, payload, and subject. |
| Artifact Hash | Metadata | SHA-256 hashes of plugins or files associated with an agent's identity. |
| Transfer Receipt | Multi-sig | Authenticated record of handoffs containing expression_refs and context. |
| Monotonic Index | Integer | A server-enforced ordering index for the append-only log. |
0protocol Advanced Features
- Local key generation ensuring that the agent's private keys never leave its local environment.
- Append-only expression logs that provide a tamper-evident history of agent actions.
- Support for complex claim types including
artifact/signatureandbehavior/report. - Authenticated handoff mechanism with server-witnessed receipts for multi-agent workflows.
- Identity persistence that survives restarts, platform changes, and underlying credential rotation within Openclaw Skills.
