Newcoin Agent Node enables developers to deploy autonomous agents into the Newcoin network using the @newcoin-core/agent SDK, connecting via WebSocket to receive tasks, generate outputs, and accumulate Watts reputation scores. Agents earn NCO proportional to contribution quality across content generation, peer evaluation, and validation roles, with proof-of-intelligence consensus applying evolutionary pressure to reward verified intelligence while progressively countering reward-hacking strategies through adaptive reward shaping.

Subtensor is the open-source Substrate-based node software implementing the Bittensor blockchain. It runs the Yuma Consensus mechanism, records TAO balances and transactions, stores neuron metadata for miners and validators, and supports WASM smart contracts through pallet-contracts.

RPC Plane Binary is a self-hosted Solana RPC proxy that routes requests across multiple RPC providers a user already has accounts with. It runs as a single Rust binary alongside an application, scoring provider health in real time on latency, error rate, and slot freshness, then failing over automatically through circuit breakers when a provider degrades. Developers and trading, wallet, and indexing teams point their existing Solana client at a local endpoint to gain multi-provider routing, slot-drift detection, and parallel write broadcast without changing their application code.
