Fairblock can be used for front-running protection, private limit orders/intents, private voting/governance, sealed-bid auctions, randomness generation, and censorship-resistant sequencers in the Cosmos and soon in the Ethereum ecosystem, modular ecosystem (Celestia), Layer 2s (Optimism, Scroll, Eclipse), and cross-chain infrastructures and applications (Axelar, Squid) to protect the contents of the transactions before execution. The goal is to empower users and protocols with the optional freedom of encrypting their transactions in order to protect them against various forms of malicious strategies and enable decentralized applications which are not previously possible.
