The SN106 validator implements a modular architecture with clear separation of concerns: (1) Multi-Chain Data Layer fetches NFT positions and tick data from enabled blockchain networks (currently Solana Raydium CLMM; Ethereum/Base Uniswap V3 coming soon), (2) Weight Calculation Engine computes subnet weights from alpha token prices, distributes to pools equally within subnets, and calculates individual NFT emissions using the concentration-proximity-liquidity scoring algorithm, (3) EMA Weight Smoothing (optional) stabilizes weight changes over time using exponential moving average with configurable alpha parameter, (4) Distribution Policy Enforcement ensures only positive-emission miners receive weights or falls back to uniform distribution if all out-of-range, (5) Subtensor Integration submits calculated weights to Bittensor chain every 20 minutes with configurable interval. The system handles multi-chain data aggregation with chain-prefixed pool identifiers to prevent conflicts. Error handling includes graceful degradation (individual chain failures don't stop execution), retry logic with exponential backoff, and comprehensive logging.

Performance optimizations include multicall batching for RPC efficiency, concurrent chain processing, weight history persistence, and connection pooling.

The validator fetches NFT liquidity positions from Solana Raydium CLMM pools staked to the SN106 contract, calculates current tick data, and fetches subnet alpha token prices from Subtensor. Subnet weights are normalized from alpha prices. Pool weights distribute subnet weights equally across pools within each subnet (with reserved share logic for non-alpha pools).

For each pool, NFT positions compete based on scoring algorithm: reward_score = (1/width^1.2) × (1/(1+distance_from_center)) × liquidity. Only positions with current_tick in [tickLower, tickUpper] range score non-zero. Miner weights aggregate across all their staked positions.

Optional EMA smoothing stabilizes weights over time. Distribution policy: if any miner has positive emission, only positive-emission miners receive non-zero weights; otherwise uniform fallback. All weights submitted to Subtensor chain with 0% burn and 100% allocation to miners (UID 0 gets 0 weight).
