Prediction markets
that price reality.

Prediction-Machine is STAR Systems' fully built forecasting platform combining LMSR automated market making, on-chain settlement, and live OSINT signal ingestion in a single auditable system.

What We Built
Six systems. One coherent platform.
Every component was engineered from first principles not stitched from third-party services. The result is a tightly integrated platform your team can own, extend, and deploy.
⚙️
LMSR Market Engine
Mathematically correct implementation of the Logarithmic Market Scoring Rule. Configurable liquidity parameter, binary-search Δq computation, and a full unit-test suite.
🔗
Smart Contract Layer
Hardhat-based MarketRegistry and LMSR AMM contracts with full event emission. Deployed and verified on Sepolia testnet with ethers.js backend sync.
📡
OSINT Subsystem
Dedicated ingestion API that persists external signals as structured evidence. OSINT events are linked directly to market resolution workflows.
💾
Persistence & Replay
PostgreSQL schema covering users, wallets, markets, trades, positions, referrals, and OSINT events. Fully reconstructable state.
🛡️
Admin Governance Console
Secure admin lifecycle management — creation, monitoring, and resolution with evidence. Every action logged immutably.
🖥️
Frontend & Deployment
Trade UI with live market cards, leaderboards, and admin dashboards. Fully Dockerized and cloud-ready deployment.

From signal to settled price.

Every trade travels through a deterministic pipeline from real-world OSINT ingestion, through on-chain AMM pricing, to final database settlement. Every trade travels through a deterministic pipeline from real-world OSINT ingestion, through on-chain AMM pricing, to final database settlement.

OSINT Signal Ingested

External intelligence is ingested via the OSINT API and persisted as structured evidence against live markets.

LMSR Price Computed

The market engine calculates the cost function for any trade size using binary search, returning a deterministic, guaranteed price.

Trade Executed On-Chain

The smart contract emits a TradeExecuted event, creating an immutable on-chain record synced back to PostgreSQL.

Market Resolved with Evidence

Admins resolve markets by linking OSINT evidence to the outcome. Positions are settled and the full lifecycle logged for audit.

Why Prediction-Machine
Not a demo. Not a clone.

— TECHNOLOGY STACK

Every layer deliberate.

The stack was chosen for auditability, ownership, and long-term maintainability — not for convenience.
