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 are siloed and fragmented, choosing to act as product directories where buyers and sellers engage in 1:1 deal making rather than facilitating the automatic distribution of data. In many instances, a product advertised on a data marketplace is sold before it even exists! The Émet Protocol eliminates these inefficiencies through an innovative cryptographic protocol that ensures atomic exchange - the buyer receives the data they expect if and only if the seller receives payment, and the data is immediately accessible.

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 on-chain 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.
