Imagine a smart contract that calculates your portfolio balance, checks a compliance rule, or computes a royalty — but never sees a single number. The data stays encrypted the entire time.
Pushes encrypted data on-chain — prices, volumes, margins. The blockchain stores them as ciphertext. Nobody else can read them.
Writes a smart contract: feed efficiency, milk quality score, cost ratio. Deploys on-chain. Sees only encrypted output — never the raw numbers.
The farmer decrypts the result and gets his indicator. The advisor never saw the raw numbers. The blockchain guarantees the computation is correct.
Each scheme optimized for a different workload — and ATSHI can switch between them on the fly.
Zero rounding errors. 100 + 50 = exactly 150. For financial calculations, voting, compliance, audit trails.
SIMD batching processes thousands of encrypted values at once. Ideal for analytics, statistics, and complex formulas on encrypted data.
Millisecond decisions. Encrypted threshold checks, private auctions, access control. Ultra-fast boolean operations on encrypted data.
Use CKKS for heavy calculations, switch to TFHE for exact comparisons — in the same transaction, no re-encryption. Unique to ATSHI.
For developers who code — and for business users who don't.
Write in Rust or AssemblyScript. Call FHE operations via native host functions — encrypt, compute, decrypt — like any API call.
// FHE host functions — native in WASM runtime
import { fhe_encrypt, fhe_compute, fhe_decrypt } from "atshi:fhe";
export function compute_royalty(
encPrice: Ciphertext,
encRate: Ciphertext
): Ciphertext {
// Multiplication happens on ciphertext.
// The node never sees price or rate.
return fhe_compute("mul", encPrice, encRate);
}
Drag & drop your business logic in a visual interface. The platform generates the FHE smart contract automatically — no cryptography expertise required.
The most comprehensive FHE library — supports all 4 schemes (BGV, BFV, CKKS, TFHE). Open-source, born from DARPA research. Used by ATSHI for on-chain encrypted computation.
openfhe.org →Google’s open-source FHE compiler. Automatically optimizes FHE circuits — selects the right scheme, manages noise budgets, generates WASM code. Makes FHE accessible without cryptography expertise.
github.com/google/heir →Encrypted positions, no front-running, no MEV. Institutional-grade privacy for on-chain trading.
Encrypted AI inference with per-call royalties. Data never exposed, model IP protected.
Royalties computed on encrypted values — sale price never visible on-chain.
Compute on encrypted patient data — diagnostics without exposure. HDS compliant.
Encrypted portfolio analysis, credit scoring, AML checks — regulators audit without seeing client data.
Encrypted supplier data, auditable compliance. Share proof without exposing business secrets.
Compute on encrypted data. Build on the first L1 with native FHE.
