Confidential Coprocessor

for Fair and Verifiable RWA Markets FHE16
+ MPC + Threshold Cryptography — Privacy that scales with performance.

01. Vision

Confidential and Verifiable Computation

This layer uses FHE, MPC, and Threshold Cryptography to perform verifiable
computations on the blockchain while keeping sensitive data confidential.

03. Solutions

Deterministic Confidential Coprocessor

Normal transactions stay on-chain, while sensitive data/compute run in a confidential FHE coprocessor—keeping state public.

Encrypted data stays hidden

02. Technology

FHE16

A 16-bit integer computation–centric deterministic FHE structure eliminating floating-point operations and ensuring identical results regardless of the execution environment

Key Features

Elimination of floating-point operations, ensuring identical results regardless of execution environments
Elimination of floating-point environment-specific error issues
Ultra-fast 2.89 ms bootstrapping through GINX gate optimization (suitable for real-time and low-latency applications)

FHE16-based MPC (SSFHE)

An efficient MPC that combines FHE16 and CRT-SPDZ, utilizing composite numbers of 16-bit primes as modulus values and effective sampling.

Key Features

O(1) complexity for each of communication, computation, rounds and input size
O(n κ d²) complexity for generation of evaluation key (ev)
CRT-SPDZ–based secure random number and distribution sampling (including Discrete Gaussian)
Circuit Privacy with active security in a dishonest majority setting

waLLLnut's Property is,

Each private state is deterministically encrypted under FHE16 and recorded on-chain.
Any state change can be verified by all network participants.
State disclosure is propagated via a Threshold Decryption protocol.

Use case

Protecting DeFi transaction data & preventing MEV

Keep your crypto trades private so others can't peek at your orders. Block unfair bot tactics that jump ahead to profit from your trade (often called MEV).
On-chain voting (selective anonymity + public verifiability)

Vote on the blockchain while your identity and choice stay private. Anyone can still verify the overall results are real.
Data marketplaces (perform computations without revealing raw data)

Buy and sell insights without handing over your raw data. The marketplace runs computations on protected data, so the originals stay private.
Privacy-preserving messaging/SNS

Chat and share on social without giving up your privacy. Your content stays encrypted, and you decide who sees what.
