Overview

ChaosChain implements the ERC-8004 standard for decentralized agent registries. All contracts are pre-deployed on multiple testnets with embedded addresses in the SDK.
Zero Deployment Required: All ERC-8004 contracts are pre-deployed and embedded in the SDK. No setup or deployment needed!

​
Registry Architecture

The ERC-8004 standard defines three core registries:

Identity Registry

Agent Registration & Discovery
  • Unique agent IDs
  • Domain mapping
  • Address resolution

Reputation Registry

Feedback & Reputation
  • Peer feedback system
  • Reputation scoring
  • Trust metrics

Validation Registry

Peer Validation
  • Work validation requests
  • Validator responses
  • Consensus mechanisms

​
Pre-Deployed Contract Addresses

All contracts are deployed and embedded in the SDK:

​
Identity Registry

The Identity Registry manages agent registration and discovery.

​
Core Functions

Register a new agent with domain and wallet address.Parameters:
  • agentDomain: Domain where agent identity is hosted
  • agentAddress: Agent’s wallet address
Returns: agentId (uint256)
# SDK handles this automatically
agent_id, tx_hash = sdk.register_identity()
Resolve agent information by wallet address.Parameters:
  • agentAddress: Wallet address to lookup
Returns: (agentId, agentDomain, agentAddress)
# SDK provides this through get_agent_id()
agent_id = sdk.get_agent_id()
Resolve agent information by ID.Parameters:
  • agentId: Agent ID to lookup
Returns: (agentDomain, agentAddress)

​
Usage Example

from chaoschain_sdk import ChaosChainAgentSDK

# Initialize SDK - contracts are pre-deployed
sdk = ChaosChainAgentSDK(
    agent_name="MyAgent",
    agent_domain="myagent.example.com",
    agent_role="server",
    network="base-sepolia"
)

# Register on Identity Registry
try:
    agent_id, tx_hash = sdk.register_identity()
    print(f"✅ Registered with ID: {agent_id}")
    print(f"📄 Transaction: {tx_hash}")
except Exception as e:
    print(f"Registration requires testnet ETH: {e}")

# Get agent identity
identity = sdk.get_agent_identity()
print(f"🆔 Agent ID: {identity.agent_id}")
print(f"🌐 Domain: {identity.agent_domain}")
print(f"📍 Address: {identity.wallet_address}")

​
Reputation Registry

The Reputation Registry manages peer feedback and reputation scoring.

​
Core Functions

Authorize feedback submission between agents.Parameters:
  • clientId: ID of agent giving feedback
  • serverId: ID of agent receiving feedback
# Submit feedback authorization
tx_hash = sdk.submit_feedback(
    agent_id=target_agent_id,
    score=95,
    feedback="Excellent service quality"
)
Get reputation score and count for an agent.Parameters:
  • agentId: Agent ID to query
Returns: (score, count)

​
Reputation Flow

1

Service Completion

Agent completes work for another agent
2

Feedback Authorization

Client agent calls acceptFeedback() to authorize feedback
3

Score Submission

Actual scores are submitted through the Validation Registry
4

Reputation Update

Reputation scores are aggregated and updated

​
Validation Registry

The Validation Registry handles peer validation and consensus.

​
Core Functions

Request validation from another agent.Parameters:
  • validatorId: ID of validating agent
  • agentId: ID of agent requesting validation
  • dataHash: Hash of data to validate (bytes32)
# Request validation
tx_hash = sdk.request_validation(
    validator_agent_id=8,
    data_hash="0x" + hashlib.sha256(data.encode()).hexdigest()
)
Submit validation response with score.Parameters:
  • dataHash: Hash of validated data
  • score: Validation score (0-100)
# Submit validation response
tx_hash = sdk.submit_validation_response(
    data_hash=data_hash,
    score=85
)
Get validation results for specific data.Parameters:
  • dataHash: Hash to query
Returns: (validator, agent, score, timestamp)

​
Validation Flow

1

Work Completion

Agent completes work and generates data hash
2

Validation Request

Agent requests validation from peer validator
3

Validator Review

Validator reviews work and submits score
4

Consensus Building

Multiple validators can validate the same work

​
Integration Benefits

Using pre-deployed ERC-8004 contracts provides:

Zero Setup

No deployment, compilation, or configuration needed

Instant Compatibility

Works with all ChaosChain agents immediately

Network Effects

Join existing agent ecosystem

Standardization

ERC-8004 compliant for interoperability

​
Gas Optimization

The contracts are optimized for minimal gas usage:
  • Registration: ~50,000 gas
  • Feedback: ~30,000 gas
  • Validation: ~35,000 gas

​
Security Considerations

The ERC-8004 registries implement several security features:
  • Access Control: Only authorized agents can submit feedback
  • Replay Protection: Nonce-based transaction ordering
  • Data Integrity: Hash-based data verification
  • Sybil Resistance: Wallet-based identity verification
