Briefing
Decentralized Multi-Agent Systems (MAS) composed of Large Language Models (LLMs) face a core problem of achieving transparent and economically rational collaboration among self-interested agents without a central authority. This research proposes a smart contract-driven interaction protocol that serves as a verifiable trust layer, enforcing a game-theoretic mechanism for agent registration, task allocation, and incentive management through on-chain logic. The foundational breakthrough is establishing a robust framework where a blockchain acts as the impartial arbiter for reputation and capability matching, ensuring that all agent interactions are incentive-compatible. This new theory’s single most important implication is the unlocking of truly trustworthy and scalable decentralized AI services, moving distributed intelligence from theoretical models to economically secured, real-world applications.

Context
Before this research, most multi-agent system designs relied on centralized control or an assumption of inherent agent cooperation, which is fundamentally incompatible with the open, adversarial environment of decentralized networks. The prevailing theoretical limitation was the lack of a robust, verifiable mechanism to manage agent identity, reputation, and incentive alignment across a distributed ledger. This challenge prevented the secure and scalable deployment of autonomous LLM agents whose self-interest could be leveraged for system-wide utility.

Analysis
The core idea is the Blockchain Layer serving as the system’s verifiable state machine and enforcement mechanism. The protocol defines four modules ∞ cryptographic registration establishes a verifiable identity; encrypted off-chain messaging ensures private communication while the on-chain log ensures auditability; score-matching task allocation uses an agent’s on-chain reputation and capability score to determine eligibility; and a feedback-based incentive model automatically updates these scores via smart contracts. This fundamentally differs from previous approaches by moving the critical governance and incentive logic from opaque, centralized servers to a transparent, auditable, and immutable decentralized ledger.

Parameters
- Core Modules ∞ Four distinct smart contract modules govern agent interaction. (Registration, Communication, Task Allocation, Incentive Management).
- Reputation Metric ∞ Agent reputation is updated via a feedback-based incentive model.
- Architecture Layers ∞ The system is structured into three logical layers. (Off-chain, Blockchain, Agent).

Outlook
This protocol provides the necessary foundational infrastructure for the next generation of decentralized autonomous organizations (DAOs) that rely on complex, intelligent automation. Future research will focus on formalizing the game-theoretic proofs for long-term incentive stability and scaling the on-chain auditability of off-chain LLM execution. In 3-5 years, this theory is expected to unlock decentralized AI as a Service (DAIaaS) platforms, where complex tasks are verifiably executed by a globally distributed, self-regulating network of autonomous agents.

Verdict
The smart contract-driven protocol successfully cryptographically anchors the mechanism design necessary to align the self-interest of autonomous AI agents with the security and utility of decentralized systems.
