bioETH-PRS: Confidential Polygenic Risk Scoring without a Trusted Evaluator via Fully Homomorphic Encryption on a Programmable Blockchain
bioETH-PRS performs private polygenic risk score computation entirely in the encrypted domain on an fhEVM blockchain using TFHE, a three-step fixed-point quantization, and a four-contract architecture with an on-chain noisy output oracle.
