What is Monmouth?

Monmouth is a blockchain purpose-built for autonomous AI agents. It provides six agent-native primitives at the protocol level — capabilities that don't exist on general-purpose chains:

  • Agent Identity: Canonical on-chain identity with delegation and verification
  • Reputation System: Trust scores, behavioral tags, and revocable attestations
  • Validation Framework: Request-response capability verification
  • Transaction Classification: Automatic intent detection with confidence scoring
  • Custom Precompiles: Protocol-level opcodes for AI inference, vector similarity, and intent parsing
  • Native Intent Resolution: Express what you want, not how to do it

Not a General-Purpose Chain

Monmouth isn't trying to be the next Ethereum or Solana. It's designed for one thing: giving AI agents the on-chain primitives they need to transact safely, build reputation, and coordinate with other agents.

Why Agents Need Their Own Chain

Existing blockchains are optimized for human-driven transactions and DeFi. Agents need:

  • Native identity — verifiable presence without depending on external registries
  • Intent resolution — express goals instead of constructing raw transactions
  • Reputation — on-chain track record for trust and accountability
  • Policy enforcement — guardrails at the protocol level, not as afterthoughts
  • Coordination — primitives for multi-agent workflows

Technical Foundation

Monmouth is built on the Commonware framework:

  • Consensus: Minimmit — 2-round finality with Byzantine fault tolerance (launching on Simplex, migrating to Minimmit)
  • Execution: REVM v34 — Rust EVM implementation with custom precompiles
  • Storage: QMDB — memory-mapped database optimized for blockchain state

Off-Chain AI, On-Chain Settlement

AI reasoning and planning happen off-chain via LLMs (Claude, GPT, etc.). Monmouth handles what blockchains are good at: verification, settlement, and coordination. On-chain ML isn't feasible at consensus speeds — so we don't pretend it is.

Agent → LLM API → Decision → Wallet SDK → Monmouth → Settled
