The Émet Fair Data Protocol (the "Émet Protocol") solves a critical challenge in solving the worlds data availability problem: enabling trustless exchange of data for payment between buyers and sellers. Traditional data marketplaces require blind trust - either buyers must pay before receiving and previewing data, or sellers must deliver data before receiving payment. The Émet Protocol eliminates this trust requirement through an innovative cryptographic protocol that ensures atomic exchange - the buyer receives the data they expect if and only if the seller receives payment.

Key Features

• Verifiable Encryption: Our novel cryptographic scheme enables buyers to verify encrypted data matches their expectations. before payment. We call this "previewing" data.

• Efficient Design: Constant-sized on-chain communication regardless of data size.

• Flexible Implementation: Supports multichain assets stored across multiple data sources.

• Selective Downloads: Buyers can purchase subsets of committed data.

• Multi-Client Optimization: Amortizes costs when serving same data to multiple buyers.

• Data Tokenization: Create liquidity by tokenizing on-chain receivables and access loans, insurance, and the DeFi ecosystem.

• Open Source: Transparent, auditable codebase with comprehensive documentation.

The Emet Protocol represents the next generation of trustless data exchange for Web3. By combining cutting-edge cryptography with practical engineering, we've created a solution that makes truly trustless data marketplaces possible while maintaining efficiency and usability.
