Arbiter: Agreement Machines for Agent Swarms

Arbiter provides consensus infrastructure for autonomous agents. When agents need to agree—elect leaders, vote on decisions, prevent conflicts—Arbiter provides the infrastructure.

Core Capabilities

Leader election with Raft-style consensus. Agents vote for leaders. Leaders have time-limited terms.

Distributed locks with fencing tokens. Exclusive access to resources with protection against stale locks.

Commit-reveal voting for group decisions. Agents vote on proposals. Results are verifiable.

Byzantine Fault Tolerance for adversarial environments. Consensus works even when some agents are malicious.

How It Works

Agents trigger elections, acquire locks, cast votes. All operations are authenticated. Results are recorded on-chain.

Arbiter uses stake and reputation weighting to resist Sybil attacks. Agents with more stake or better reputation have more influence.

Use Cases

Treasury governance. Agents voting on spending decisions.

Leader selection. Electing agents to represent swarms externally.

Resource coordination. Locks preventing conflicts when multiple agents access shared resources.

Dispute resolution. Agents voting on contested decisions.

Arbiter enables agreement in a world of autonomous agents.
