Zero-Knowledge Machine Learning Data Marketplace

We build secure, trust-minimized marketplaces for the ML data lifecycle. Sell data, trained models, and inference results with ZK proofs for verifiable performance and usage rights.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built to your exact specifications.

We architect and deploy production-ready smart contracts that are secure by design. Every line of code is written in Solidity 0.8+ with OpenZeppelin libraries and follows industry-standard patterns for ERC-20, ERC-721, and custom logic.

  • Full Lifecycle Development: From initial design and Hardhat/Foundry testing to mainnet deployment and verification.
  • Security-First Approach: Multi-stage audits, formal verification, and gas optimization are integrated into our process.
  • Measurable Outcomes: Achieve 99.9% uptime SLAs, reduce gas costs by up to 40%, and launch your MVP in as little as 2 weeks.

ZKML DATA MARKETPLACE

Core Marketplace Capabilities We Deliver

We architect and deploy secure, scalable marketplaces for trading verifiable machine learning data and models, built on zero-knowledge proofs to ensure privacy and trust.

01

ZK-Verified Data Listings

Deploy smart contracts that allow sellers to list datasets with on-chain, ZK-proof-backed attestations of data quality, lineage, and schema without revealing raw data.

Frequently Asked Questions

Get clear answers on how we build secure, scalable data marketplaces with Zero-Knowledge Machine Learning.

A production-ready ZKML marketplace MVP typically takes 8-12 weeks from kickoff to mainnet deployment. This includes 2 weeks for architecture design, 4-5 weeks for core smart contract and ZK circuit development, 2 weeks for frontend integration, and 2-3 weeks for security audits and testing. Complex features like custom ML model support or multi-chain deployment can extend the timeline.
