Federated Learning exists outside Web3. Sinapse Protocol integrates Web3 infrastructure to replace trust in centralized orchestrators with deterministic cryptoeconomic proofs.
Every model update generated by a hospital node produces a unique cryptographic hash recorded immutably in a Solana Program Derived Address (PDA). This prevents retroactively falsifying contribution logs or altering model version histories.
Rewards are disbursed programmatically via smart contracts upon verification of submitted weights. Eliminates central administrative intermediaries, guaranteeing exact 1-to-1 payout execution for verified training rounds.
Each hospital's verified contribution score is aggregated across the network through Arcium's confidential MPC nodes via secure multi-party computation. No individual hospital's score is exposed to a central server or to peer institutions before the aggregate total is revealed.
The operational lifecycle of a distributed diagnostic model update across node networks.
Hospital nodes train diagnostic models locally against isolated clinical datasets (e.g., MedMNIST benchmarks).
Local weight update hashes are committed directly to the hospital's PDA on Solana Devnet via Anchor RPC calls.
Verified contribution scores pass through the Arcium confidential MPC network, aggregated without any single hospital's score being exposed.
Global state model increments on-chain, triggering token reward issuance to verified hospital wallet addresses.
The datasets evaluated during simulation testing (including MedMNIST) are standardized research benchmarks. Per dataset publisher terms, these materials are intended exclusively for algorithmic research and infrastructure validation, not for direct clinical diagnosis or medical decision-making. Sinapse Protocol delivers the decentralized coordination, verification, and cryptoeconomic infrastructure; it does not replace medical diagnostic devices or software.
Current devnet build: Arcium confidentially aggregates each hospital's verified contribution score. Full model-weight-level confidential aggregation is on the protocol roadmap.
