Vanta

Vanta is a decentralized on-chain trading signals network. Miners run local REST API servers (port 8088) to submit trading orders via their Bittensor hotkeys. Orders are sent to validators who process them, track positions on disk (validation/miners/{hotkey}/), maintain live price feeds from Polygon/Tiingo APIs, calculate real-time returns, and eliminate miners exceeding 10% drawdown.

Validators set weights every 5 minutes using debt-based scoring (comparing previous week's PnL×penalties to current emissions). Entity miners extend this with subaccounts: a parent entity hotkey manages multiple synthetic hotkeys ({entity_hotkey}_{id}), each trading independently. Validators broadcast positions and eliminations via WebSocket/REST API for downstream consumers (dashboards, data providers).

Metagraph client aggregates validator data and hotkey listings. Subtensor handles on-chain weight setting with commit-reveal mechanism. Challenge period gating ensures new miners prove capability (8-10% return, <5% drawdown) within 90 days before earning full payouts.

Emissions ledger tracks ALPHA/TAO/USD tokens earned in 12-hour checkpoints. Performance ledger tracks PnL, fees, drawdown, and portfolio returns. Penalty ledger applies multipliers for drawdown, risk profile, minimum collateral, and risk-adjusted performance.

Debt ledger combines these into: Needed Payout (previous week PnL × penalties) minus Actual Payout (current week emissions) = Remaining Debt. Weights distributed proportionally to remaining debt. Average Daily PnL has 100% weight; other metrics (Calmar, Sharpe, Omega, Sortino, Statistical Confidence) tracked but have 0% weight.

Recency weighting: most recent 10 days = 25% of score, 30 days = 50%, 70 days = 75%. Annualized risk-free rate normalization applied. Challenge period miners earn no direct payouts but receive 1× dust baseline.

Eliminated miners receive 0× weight and cannot trade until deregistered and re-registered.
