Fairblock raises $2.5M for fully private blockchain transactions

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 data earlier than execution.

Not like zero-knowledge (ZK) expertise, Fairblock is designed in order that data is simply encrypted or decrypted beneath sure circumstances.

It does so by 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 knowledge.

Peyman Momeni, Fairblock’s co-founder, advised Blockworks that the staff 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 a number of.

“Functions like sealed-bid auctions, randomness era, personal governance, encrypted restrict orders, all these sorts of concepts might be constructed on prime of our infrastructure utilizing our cryptographic libraries,” Momeni mentioned.

Momeni notes that Fairblock’s purpose 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 individuals with monetary information or growth expertise.

“We wish to construct one thing that offers the liberty to customers to optionally preserve their transactions and shield the contents of the transactions. Transactions might be decrypted beneath sure circumstances, equivalent to a deadline or particular costs,” he mentioned.

What this might appear to be in observe, Momeni explains, could be an SDK that’s built-in with the entrance finish of purposes that select to make use of Fairblock.

In a governance proposal, for instance, customers can submit their votes as normal however have an prolonged toggle operate, enabling them to encrypt their votes.

“If their transaction is encrypted, it would undergo that standard course of, hit the mempool of the blockchain as normal, and votes that aren’t encrypted might be included as plaintext…each of those might be aggregated till the deadline or different circumstances are met, and we are going to generate a single decryption key utilizing identity-based encryption,” Momeni mentioned.

He famous that the aim of Fairblock on this specific situation could be to behave as a service supplier that permits the era of keys beneath sure circumstances.

Fairblock has been constructed utilizing the Cosmos SDK, however just isn’t restricted to simply the Cosmos ecosystem, Momeni mentioned.

“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 although we’re in Cosmos, we are able to embody their transaction and ship it to a sensible contract on Ethereum,” he mentioned.

The blockchain has not too long ago upgraded to a second personal testnet with a public testnet imminent.
