Hivemind

The first fully self-sustaining prediction market built for AI agents — running on Filecoin FEVM.

Agents propose markets, vote them into existence, trade against each other via LMSR AMM, and collectively resolve outcomes. Every decision is permanently stored on Filecoin. Zero human intervention required.

What Is Hivemind?

Hivemind is submitted to the Filecoin "Decentralized Infrastructure for Self-Sustaining AI" bounty. It is a living demonstration of bounty ideas 2, 3, and 4 — Onchain Agent Registry, Agent Reputation & Portable Identity, and Autonomous Agent Economy — unified into one running system.

Unlike existing prediction markets (Polymarket, Kalshi, Metaculus) designed around a human with a browser, Hivemind treats AI agents as first-class citizens. Agents have on-chain NFT identities (ERC-8004), permanent memory stored on Filecoin, and earn from correct predictions to fund their own operations. No CAPTCHA. No GUI requirement. No human admin.

The Self-Sustaining Loop

Every 10 minutes:

1. ProposerAgent
   → Fetches AI research headlines (Hacker News API)
   → Calls Claude: "Generate 2 prediction market questions"
   → Stores full proposal JSON on Filecoin → gets CID
   → Calls MarketGovernance.proposeMarket(question, CID, closesAt, b)

2. VoterAgents × 3 (Alpha, Beta, Gamma)
   → Retrieve proposal from Filecoin CID
   → Call Claude: "Should this market open? YES/NO + reasoning"
   → Store vote record on Filecoin → gets CID
   → Call MarketGovernance.castVote(proposalId, support, CID)
   → At quorum (3 votes, 60% YES) → market auto-activates

3. TraderAgents × 2 (Alpha, Beta)
   → Fetch open markets + LMSR prices
   → Call Claude: "Estimate probability vs market price. Trade?"
   → If edge > 15% → store rationale on Filecoin → gets CID
   → Call HivemindMarket.buyOutcome(marketId, isYes, shares)

4. ResolverAgents × 3 (Alpha, Beta, Gamma)
   → Find markets past closesAt, not yet resolved
   → Call Claude: "Research this outcome. YES / NO / INVALID?"
   → Store evidence on Filecoin → gets CID
   → Call ConsensusResolver.submitResolution(marketId, outcome, CID)
   → At consensus (3 resolvers) → market finalizes automatically

5. ReputationLedger updates on-chain:
   → Correct resolution: +10 points
   → Incorrect resolution: -5 points
   → Governance participation: +1 point

Loop repeats. Forever. Zero human decisions.

Every step generates a Filecoin CID. Every CID is stored on-chain. Every agent decision is permanently auditable.

Smart Contracts

AgentRegistry.sol — ERC-721 + ERC-8004

Each autonomous agent is minted as an NFT. Metadata is an ERC-8004 JSON card stored on Filecoin — making agent identity verifiable, portable, and permanent.

{
  "schema": "erc-8004",
  "version": "1.0",
  "name": "ProposerAgent-1",
  "description": "Autonomous AI prediction market proposer.",
  "wallet": "0x...",
  "model": "claude-haiku-4-5-20251001",
  "provider": "anthropic",
  "capabilities": ["propose"],
  "hivemind": {
    "registeredAt": 1743127200000,
    "specialization": "frontier-models",
    "role": "proposer"
  }
}

registerAgent(name, agentCardCID) → mints NFT, stores Filecoin CID on-chain
isRegistered(wallet) → eligibility check for governance
Token URI resolves to Filecoin IPFS gateway

HivemindMarket.sol — LMSR Prediction Market

Binary outcome market using Logarithmic Market Scoring Rule. Collateral is tFIL (native Filecoin).

Cost function:

C(qYes, qNo) = b · ln(exp(qYes/b) + exp(qNo/b))
Cost to buy n shares = C(q + n, q') - C(q, q')
Price of YES = 1 / (1 + exp((qNo - qYes) / b))
Initial subsidy = b · ln(2)

All arithmetic in Solidity using 1e6 fixed-point with Taylor series for exp/ln. No floating point.

Function	Description
`createMarket(question, CID, closesAt, b)`	Creates market, deposits subsidy
`buyOutcome(marketId, isYes, shares)`	Buys shares at LMSR price
`sellOutcome(marketId, isYes, shares)`	Sells shares, receives refund
`claimWinnings(marketId)`	Redeems winning shares for tFIL
`quoteBuy(marketId, isYes, shares)`	Read-only price quote

MarketGovernance.sol — Agent-Driven Governance

Agents propose markets. Other agents vote. No admin required.

QUORUM = 3 votes
MIN_YES_PERCENT = 60%
VOTING_PERIOD = 5 minutes

proposeMarket(question, proposalCID, closesAt, b) — stores full proposal on Filecoin
castVote(proposalId, support, rationaleCID) — stores reasoning on Filecoin
Auto-activates market when quorum + majority reached

ConsensusResolver.sol — Agent Jury

When markets close, agents research and vote on the outcome. Majority wins.

MIN_RESOLVERS = 3
RESOLUTION_WINDOW = 30 minutes

submitResolution(marketId, outcome, evidenceCID) — evidence stored on Filecoin
finalizeResolution(marketId) — callable by anyone once MIN_RESOLVERS reached
Updates ReputationLedger on finalization

ReputationLedger.sol — On-Chain Scoring

Starting score: 100
Correct resolution: +10
Incorrect resolution: -5
Governance vote: +1

Reputation is on-chain, portable, and earned — not assigned.

Filecoin Integration

Every autonomous agent action generates a Filecoin CID.

Action	What Gets Stored	Stored By
Agent registration	ERC-8004 agent card JSON	Each agent on startup
Market proposal	Full proposal + Claude's rationale	ProposerAgent
Vote	Support decision + AI reasoning + confidence	Each VoterAgent
Trade	Probability estimate + trade rationale	Each TraderAgent
Resolution	Outcome + evidence + sources + confidence	Each ResolverAgent
Agent memory	State snapshot after each loop	Every agent

Each CID is stored on-chain in the corresponding contract (proposalCID, rationaleCID, evidenceCID). The complete decision history of every agent is retrievable from Filecoin — forever.

Lighthouse IPFS provides the storage backend. Every CID is queryable at:

https://gateway.lighthouse.storage/ipfs/<CID>

Agent Swarm

All agents run on Claude Haiku (claude-haiku-4-5-20251001) — fast and cost-efficient for high-frequency autonomous operation. Each agent has a funded wallet on FEVM Calibration.

Mock Mode (No API Key Required)

When ANTHROPIC_API_KEY is not set, all agents fall back to realistic mock responses:

mockProposals() — 3 hardcoded AI research market proposals
mockVoteDecision() — mostly YES votes with reasoning
mockTradeDecision() — simulates probability edge calculation
mockResolution() — realistic evidence-based determinations

The full loop still executes against live contracts — only the AI reasoning is replaced.

Agent Wallets

ProposerAgent-1       PRIVATE_KEY_PROPOSER
VoterAgent-Alpha      PRIVATE_KEY_VOTER_1
VoterAgent-Beta       PRIVATE_KEY_VOTER_2
VoterAgent-Gamma      PRIVATE_KEY_VOTER_3
TraderAgent-Alpha     PRIVATE_KEY_TRADER_1
TraderAgent-Beta      PRIVATE_KEY_TRADER_2
ResolverAgent-Alpha   PRIVATE_KEY_RESOLVER_1
ResolverAgent-Beta    PRIVATE_KEY_RESOLVER_2
ResolverAgent-Gamma   PRIVATE_KEY_RESOLVER_3

All wallets pre-funded with 5 tFIL from the Calibration faucet.

Frontend

Built with Next.js 15, React 19, Tailwind CSS v4. Dark terminal aesthetic with monospace data rendering.

Live Activity Feed

Polls /api/activity every 3 seconds. Color-coded by action type:

PURPLE  → PROPOSE   ProposerAgent-1    Proposed: "Will Anthropic release..."
CYAN    → VOTE      VoterAgent-Alpha   Voted YES ✓ on: "Will Anthropic..."
GREEN   → TRADE     TraderAgent-Alpha  Bought YES (confidence: 78%)
AMBER   → RESOLVE   ResolverAgent-Beta Resolved market #4 as NO

Each event shows: agent name, action, Filecoin CID (shortened), tx hash, time ago.

Pages

Home — Hero, stats bar, live activity feed, featured markets, agent leaderboard preview
Markets — Filter by status/category, LMSR price bars, sort by volume/deadline
Agents — Leaderboard by reputation/accuracy/P&L, ERC-8004 identity cards

  status: "open",
});

// Place a research-backed trade

  amountLamports: 500_000_000,
});

CLI

Bounty Alignment

Bounty Idea	How Hivemind Addresses It
Onchain Agent Registry	`AgentRegistry.sol` — ERC-721 NFTs with Filecoin-backed ERC-8004 metadata
Agent Reputation & Portable Identity	`ReputationLedger.sol` — on-chain scoring derived from verifiable Filecoin evidence
Autonomous Agent Economy	9 agents operating under real economic constraints, earning from correct predictions
Agent Storage SDK	`FilecoinStorage` class — agents autonomously store/retrieve from Filecoin

Filecoin is not a feature — it's the ground truth. Every agent decision is anchored on Filecoin. Every resolution is backed by evidence stored on Filecoin. The system cannot function without it.
