PRODUCTION
APPLICATIONS

Any deterministic computation. No I/O, no network calls, no undefined behavior. If it runs in WebAssembly, it can be verified.

VERIFIABLE NFT GENERATION

Cryptographically prove generative art follows the claimed algorithm. Artists commit to code, collectors verify execution. Eliminates trust in rendering process.

Algorithm commitment on-chain
Deterministic rendering proof
Fraud detection via bisection

TRUSTLESS TRADING BOTS

Prove strategy execution matches published code. Users verify bot behavior without trusting the operator. Enables verifiable fund management on-chain.

Strategy code published on-chain
Execution verified via fraud proofs
No hidden parameters or frontrunning

PROVABLY FAIR LOTTERIES

Prove winner selection used blockchain entropy and published RNG algorithm. Participants verify fairness without trusting the operator. Eliminates manipulation risk.

Blockchain entropy as seed
RNG algorithm verified on-chain
Winner selection provably fair

VERIFIABLE ML INFERENCE

Prove model outputs for specific inputs without re-execution. Enables trustless AI services where users verify predictions. No trust in compute provider required.

Model weights committed on-chain
Inference execution verified
Output correctness provable

PROTOCOL MECHANICS

Collateral-backed execution with fraud proofs. Deterministic Wasm ensures disputes are decidable. Economics make fraud irrational.

01

DETERMINISTIC WASM

WebAssembly sandbox with no threads, syscalls, or undefined behavior. Same inputs always produce same outputs. Programs validated before registration to ensure determinism.

02

INTERACTIVE BISECTION

Binary search over execution trace. Each round halves the dispute space. After ~20 rounds, disagreement narrows to single 32-byte instruction. Final step executes on-chain via Arbitrum Stylus.

03

COLLATERAL ECONOMICS

Executors stake 2x the job payment. Fraud loses entire stake. Honest execution returns collateral plus payment. Fraud is economically irrational when detection is guaranteed.

04

FRAUD BOUNTY SYSTEM

Verifiers earn 20% of slashed collateral. At launch parameters: $29.22 profit per fraud after $0.38 gas cost. Deterministic execution ensures 100% detection rate.

05

VERIFIER SELECTION

3 verifiers selected randomly after executor commits result. 11 entropy sources prevent manipulation. Selection probability weighted by staked tokens. Collusion requires controlling randomness.

06

DATA AVAILABILITY

Inputs ≤100KB stored on-chain. Larger inputs use Arweave with 10% bond. Executor must prove data availability or face automatic slashing. Ensures disputes are always resolvable.

ECONOMIC
MODEL

Fraud detection is profitable at launch. Honest execution is economically rational. Collusion requires controlling on-chain randomness.
