Introduction Fairblock Network
TL;DR:
What is the Fairblock Motivation[2]
Fairblock is working on fully on-chain privacy solutions that serve as building blocks for decentralized applications and networks.Fairblock developing encryption and privacy-preserving services that can be used right in the frontend of decentralized applications, as well as directly in networks seeking privacy at the protocol level, from Ethereum to the latest rollups. The solution is portable and as user-friendly as HTTPS is for web2, without relying on centralized parties to keep transactions private.
Fairblock Delivers the Practical Privacy Tools Enabling Novel Web3 Applications[1]
Fairblock is built for delivering programmable privacy throughout the blockchain space in a modular way. Developers can leverage Fairblock’s encryption tools to create more compelling decentralized applications, and users are afforded much-needed protection from malicious actors who are currently taking advantage of publicly-visible financial transaction flows.
The Imperative for Decentralized Programmable Privacy Solutions
Without a decentralized programmable privacy solution, the design space for truly permissionless apps is limiting. Builders need robust, simple-to-use encryption tools in order to escape these narrow confines and create applications that most people will actually want to use.
Transaction privacy gives DeFi users powerful safeguards against a variety of tactics that manipulative actors are currently using against them.
Fairblock’s Enables Privacy Across All Blockchain Ecosystems
Fairblock serves as a hub that exports privacy-as-a-service across the increasingly interconnected blockchain space. Through a modular architecture, it enables privacy on any blockchains that harness Fairblock’s state-of-the-art cryptographic tools. Additionally, rather than going all-in on a single cryptographic tool such as zero-knowledge encryption (ZK), Fairblock empowers blockchains and apps with several forms of encryption, each suited to enabling a distinct set of user experiences.
Fairblock’s Capabilities
Fairblock is making several advanced cryptographic schemes including threshold identity-based encryption, threshold fully homomorphic encryption, and witness encryption available.
Using identity-based encryption (IBE), Fairblock allows for encrypting the contents of transactions before they’re posted on-chain all the way up until their execution. Decryption of those transactions can also be customized by associating the encryption with particular conditions, such as when a voting period ends or when certain market conditions occur.
Fully homomorphic encryption (FHE) will allow for even greater flexibility for designing privacy-preserving applications. By allowing for computation on encrypted data, this cryptography scheme enables use-cases such as on-chain voting where only the aggregate tally in a vote is revealed, while individual votes remain private. In DeFi, it allows for trades to remain private even when they’re executed
With witness encryption, Fairblock will become an even more secure and decentralized system by allowing for encryption and decryption that doesn’t rely on the trust assumptions associated with using the validator set of its proof-of-stake blockchain for encryption and decryption.
With Fairblock’s SDK, users can effortlessly encrypt transactions while also defining specific “conditions” e.g. block number for either partial or complete decryption and execution of these transactions.
