Fairblock is hoping to make conditional decryption and pre-execution privateness a actuality.
Conditional decryption refers to permitting customers to set circumstances that allow protocols to execute transactions with out revealing any on-chain info earlier than execution.
Not like zero-knowledge (ZK) expertise, Fairblock is designed in order that info is simply encrypted or decrypted below sure circumstances.
It does so by means of superior cryptography, together with identity-based encryption and witness encryption. The corporate can be wanting into absolutely homomorphic encryption, or FHE, which can allow computations to be carried out on absolutely encrypted information.
Peyman Momeni, Fairblock’s co-founder, informed Blockworks that the crew had secured $2.5 million in pre-seed funding to construct this infrastructure.
The funding spherical was led by Galileo and noticed participation from Lemniscap, Dialectic, Robotic Ventures, GSR, Refrain One, Dorahacks, and Reverie, simply to call just a few.
“Purposes like sealed-bid auctions, randomness era, non-public governance, encrypted restrict orders, all these sorts of concepts may be constructed on prime of our infrastructure utilizing our cryptographic libraries,” Momeni stated.

Momeni notes that Fairblock’s objective is to decrease dangers for common crypto customers, including that there are nonetheless many points with transactions being front-run or having the contents of a transaction leaked, making a market skewed to favor folks with monetary data or growth expertise.
“We need to construct one thing that provides the liberty to customers to optionally preserve their transactions and defend the contents of the transactions. Transactions may be decrypted below sure circumstances, comparable to a deadline or particular costs,” he stated.
What this may appear to be in observe, Momeni explains, could be an SDK that’s built-in with the entrance finish of functions that select to make use of Fairblock.
In a governance proposal, for instance, customers can submit their votes as ordinary however have an prolonged toggle operate, enabling them to encrypt their votes.
“If their transaction is encrypted, it should undergo that ordinary course of, hit the mempool of the blockchain as ordinary, and votes that aren’t encrypted can be included as plaintext…each of those can be aggregated till the deadline or different circumstances are met, and we’ll generate a single decryption key utilizing identity-based encryption,” Momeni stated.
He famous that the aim of Fairblock on this explicit situation could be to behave as a service supplier that allows the era of keys below sure circumstances.
Fairblock has been constructed utilizing the Cosmos SDK, however shouldn’t be restricted to simply the Cosmos ecosystem, Momeni stated.
“You may consider us as an Axelar or an oracle for offering decryption keys to shopper chains — which may embody a rollup or a sensible contract, so despite the fact that we’re in Cosmos, we will embody their transaction and ship it to a sensible contract on Ethereum,” he stated.
The blockchain has lately upgraded to a second non-public testnet with a public testnet imminent.
