what's Fairblock?
Fairblock is a chain-agnostic infrastructure protocol enabling programmable privacy and conditional decryption for blockchain transactions. It protects users from front-running and MEV by encrypting transaction details in mempools, revealing them only under predefined conditions. This supports confidential apps (cApps) like private stablecoin transfers, encrypted limit orders, sealed-bid auctions, and fair lending, across ecosystems including Cosmos SDK, OP Stack, Solana, Arbitrum, and Nibiru. Fairblock leverages advanced cryptography such as identity-based encryption (IBE), witness encryption, and explorations into fully homomorphic encryption (FHE). Transactions are submitted encrypted with commitments, decrypted via threshold shares only at target blocks, ensuring dynamic confidentiality without performance overhead. Modular architecture exports privacy-as-a-service, allowing developers to build tamper-proof DeFi primitives and compliant onchain finance with selective disclosure.
Fairblock partnered with Stable as Day 1 privacy partner for mainnet, enabling confidential payments.
