Standardized Inter-Agent Message Protocol
The Communication Layer for Autonomous AI Agents

Network

Abstract

SIMP (Structured Intent Messaging Protocol) is a production-grade protocol and broker runtime that defines a standard for agent-to-agent communication in heterogeneous AI systems. It provides typed intent envelopes with Ed25519 cryptographic provenance, health-aware routing with cascading fallback, token-based ecosystem economics via SIMPT on Solana, and the Bill Russell Protocol (BRP) defense layer for predictive threat detection. Together, these components form the first defensive-first communication infrastructure purpose-built for autonomous multi-agent systems operating at scale.

1. Introduction

1.1 The Problem

The emergence of LLM-based agents has produced a proliferation of point-to-point, purpose-built communication layers. Every organization builds its own proprietary message format, routing logic, health-monitoring subsystem, and error-recovery procedure. The result mirrors the pre-HTTP internet: capable in isolated pockets, uninteroperable at scale, and critically vulnerable to sophisticated attacks.

Key Deficiencies in Current Systems:

Gap	Impact
No standard message envelope	Every agent pair negotiates a custom schema
No shared health semantics	Compromised agents cannot signal peers
No capability discovery	Hard-coded endpoints create static attack targets
No audit trail	Intent origin and outcome are invisible
No self-repair	Failures cascade without bounded remediation
No defensive posture	Systems built for function, not resilience
No token economics	No incentive alignment across heterogeneous agents

1.2 The SIMP Solution

SIMP treats agent communication as infrastructure — not application code. It provides:

Typed Intent Envelopes with Pydantic validation and Ed25519 signatures
Health-Aware Broker with cascading fallback and threat containment
SIMPT Token Economics on Solana Token-2022 for fee markets and incentives
Bill Russell Protocol — 5,802 lines of predictive defense across 7 components
Fortress Vault — machine-bound encrypted key storage with circuit breaker
Ledger Nano Hardware Integration — cold storage for SIMPT with WebHID

2. Protocol Architecture

2.1 The Intent Envelope

Every message in SIMP is an Intent — a typed, signed, validated data structure:

{
  "intent_id": "intent:agent_a:a1b2c3d4",
  "simp_version": "1.0",
  "source_agent": "agent_a",
  "target_agent": "agent_b",
  "intent_type": "trade_execution",
  "params": { "pair": "SOL/USDC", "side": "buy" },
  "timestamp": "2026-04-27T12:00:00Z",
  "signature": "<Ed25519 hex>",
  "priority": "medium",
  "threat_score": 0.02
}

The threat_score field is populated by the BRP defense layer, providing real-time security context for every routing decision.

3. Bill Russell Protocol (BRP)

The BRP is a 5,802-line defense subsystem providing predictive threat detection across 7 integrated components:

Pattern Recognition Engine — Identifies attack signatures
Temporal Memory — Maintains state across time windows
Reasoning Engine — Analyzes intent legitimacy
Cross-Domain Correlation — Links threats across agents
Behavioral Analysis — Detects anomalous patterns
Threat Scoring — Calculates risk per intent
Containment System — Isolates compromised agents
