Four-Layer Architecture
Exact Arithmetic
All computation in exact integer and rational arithmetic. Zero floating-point operations at any layer -- enforced at compile time, not by convention. Results are deterministic and bit-identical across platforms, compilers, and architectures. Formally verified.
K-Elimination
Exact division in Residue Number Systems. For 60 years, RNS division required expensive full reconstruction that serialized parallel computation. K-Elimination solves this exactly, enabling practical RNS-based FHE for the first time.
Integrity Verification
RNS encoding with algebraic integrity checking. Corrupted operations -- whether from hardware faults or adversarial inputs -- are detected at the first computation step, not at the end of the circuit. Failed integrity triggers immediate destruction in Kiosk mode.
Three-Lock FHE
Unlimited-depth homomorphic encryption with Three-Lock conjunction security. Three independent protection layers during re-encryption. Three verified bootstrap paths: circular, non-circular (KSK), and auto-triggered. 935+ tests, all passing.
Why Integer-Only
Every floating-point operation is a precision loss. In isolation, the error is negligible. Across thousands of operations -- training a neural network, evaluating a deep circuit, computing a financial model -- errors compound into unreliable results. NINE65 eliminates this entirely. The answer is exact, or the system tells you it cannot compute it. There is no silent degradation.
