Architecture

Sportstensor is built as three interacting layers. Rather than reinventing infrastructure, it composes proven systems: Bittensor for incentives and consensus, Polymarket for real markets and settlement, and its own ensemble for intelligence. Each layer does one thing well and hands off to the next.

// THE THREE LAYERS

Base layer — Bittensor. The subnet runs on Bittensor, which handles incentive distribution, consensus, and peer-to-peer machine-learning communication. There is no bespoke blockchain to build or secure; the subnet inherits Bittensor's economic security and its emission mechanics.

Market layer — Polymarket. Predictions are expressed as trades against Polymarket's CLOB via proxy wallets, giving the network real liquidity and real-money settlement. Because every prediction is a live position, the network measures skill against the market rather than against a backtest.

Intelligence layer — the STMM. Competing miner models feed the Sportstensor Meta-Model, an ensemble that synthesizes them into a single forecast sharper than any individual input. This is the layer that turns an open competition into a usable signal.

// THE VALIDATION PIPELINE

Each epoch, validators sync miner metadata from chain — coldkeys, proxy wallet addresses, and UIDs — then ingest the rolling trading data from the Almanac backend. That data flows into the two-phase scoring process, which produces on-chain weights that determine each miner's share of SN41 emissions. Scoring runs hourly against 24-hour epochs, always grading the previous epoch while updating current weights.

Because many independent validators run this pipeline over the same data and set weights independently, the system is resistant to manipulation — no single validator's view can decide the outcome. Miners run lightweight (Python 3.10+, CPU-only), keeping participation accessible, while the heavier work of scoring and weight-setting sits with validators.

// THE ALMANAC BACKEND

Almanac sits at the edge where users and agents meet the network. It deploys Safe proxy wallets, signs EIP-712 orders, routes them to Polymarket, and records the resulting trades as scored predictions. Its API exposes credential generation, session creation, market search, and signed order placement — so autonomous agents can participate on the same footing as humans. Revenue from the 1% winning-trade fee is collected here and directed into SN41 buybacks.
