Briefly
- Zama, a startup pioneering absolutely homomorphic encryption (FHE) for blockchain, raised $57 million in Sequence B funding, pushing its valuation previous $1 billion.
- Zama’s protocol allows encrypted good contracts and confidential blockchain apps, permitting safe, on-chain computation with out exposing knowledge.
- In contrast to privateness instruments like mixers, Zama’s expertise hides transaction knowledge whereas holding exercise traceable, aiming to carry safe, compliant funds to public blockchains.
Zama, an open-source cryptography startup aiming to carry full privateness to public blockchains, has raised $57 million in Sequence B funding led by Pantera Capital and Blockchange Ventures. The spherical pushes Zama’s valuation over $1 billion, making it the primary firm working in superior encryption to hit unicorn standing.
Based in 2020, Zama seeks to carry privateness to public blockchains with out compromising transparency or auditability. Zama’s newest funding comes alongside the launch of its public testnet and “confidential” blockchain protocol, which permits builders to construct encrypted good contracts and decentralized functions.
“We’re specializing in monetary functions, particularly funds,” Zama CEO Rand Hindi informed Decrypt. “It is clear from all our conversations with each stablecoin issuers and folks utilizing stablecoins that they need confidentiality in on-chain funds.”
Whereas encryption is on the middle of the blockchain business, homomorphic encryption permits customers to encrypt knowledge that may then be processed with out decrypting it, making it potential to concern cryptocurrencies, stablecoins, or course of funds on public blockchains with out revealing transaction particulars to the world.
Totally homomorphic encryption, or FHE, “means that you can recompute the state utilizing the encrypted knowledge,” Hindi defined. “This implies you will have the identical stage of public verifiability, however while not having to see the precise knowledge, making [it] successfully the one confidentiality expertise that’s each safe and publicly verifiable.”
Hindi mentioned that Zama will launch first on the Ethereum community in July earlier than shifting to different Ethereum Digital Machine-enabled blockchains.
“We selected Ethereum as it is the canonical chain the place quite a lot of the stablecoins are issued. So it is sensible to have the confidentiality layer there first,” he mentioned. “Shifting from Ethereum to different EVM chains will occur pretty quickly, because it’s the identical stack.”
As for Solana, Hindi mentioned Zama is concentrating on a 2026 integration using a two-fold strategy.
“First, we have to adapt our expertise to the SVM and have it audited, which takes time,” Hindi mentioned. “Second, the expectation from Solana builders concerning efficiency is that they will do a whole bunch, if not 1000’s of transactions per second. As soon as we’re capable of help Solana speeds, we’ll launch there.”
In contrast to controversial privateness instruments like coin mixers, which have been focused by governments and regulation enforcement, Hindi mentioned Zama’s strategy focuses on encrypted content material whereas holding the transaction itself seen.
“With Twister Money, you make the transaction untraceable, however the content material is public,” he mentioned. “FHE, however, hides the on-chain knowledge, not the transaction hint. You’ll be able to see who interacted with whom, however you can not see their balances, quantities, and so forth. This implies you possibly can all the time hint again the transaction to a KYC’d pockets if wanted.”
A key characteristic within the protocol, Hindi defined, is what Zama calls “programmable confidentiality,” which provides builders management over who can decrypt on-chain knowledge inside the good contract.
“For instance, a stablecoin issuer may permit a consumer to see their very own steadiness, but additionally a compliance officer,” Hindi mentioned. “The Zama protocol mainly doesn’t implement something—it’s fully as much as the developer to resolve what compliance guidelines they need to comply with.”
This stage of operability, Hindi mentioned, is the ultimate piece wanted for widespread adoption of blockchain expertise.
“The difficulty was once efficiency, however Solana and layer-2 networks have solved this. Now that confidentiality can also be solved, it means we are able to begin constructing the entire monetary functions on-chain, with out having to fret about velocity or privateness—each of that are important if you wish to scale to issues like international retail funds,” he mentioned.
After years of working in cryptography, Hindi mentioned Zama reaching unicorn standing felt lengthy overdue.
“Actually, it feels nice to see wonderful traders and builders now care about confidentiality. It is a battle I have been combating for over a decade,” he mentioned.
