StarkWare launches S-two prover for client-side ZK proofs
Blockchain firm StarkWare has unveiled zero-knowledge (ZK) prover STARK Two (S-two), enabling enhanced privateness and verification on on a regular basis units like telephones, laptops and browsers.
The corporate stated the brand new ZK prover permits customers to generate advanced cryptographic proofs from the shopper aspect. This implies customers can generate ZK-proofs straight on their units as an alternative of counting on a server or cloud infrastructure, opening the door for quicker and extra personal functions throughout the web.
“S-two will deliver STARK proving to on a regular basis units, and open the door for brand new real-world proving use circumstances,” stated Eli Ben-Sasson, StarkWare co-founder and CEO, including that the device may empower the following wave of ZK functions.
The corporate stated the ZK prover is now out there in public alpha and is about to roll out on Starknet, its Ethereum layer-2 scaling resolution, later this 12 months.
StarkWare says new ZK prover is 39 instances quicker than outdated options
StarkWare stated that benchmark checks for the S-two ZK prover confirmed that it was 39 instances quicker than earlier options. The efficiency leap allows smoother experiences in privacy-enhancing functions.
The improve additionally permits use circumstances in personal transactions, ZK-based identification and verifiable synthetic intelligence. StarkWare stated S-two runs on CPUs, GPUs and can quickly be on browsers.
“For years we’ve known as the prover our magic wand, a device that transforms advanced computation right into a easy proof,” Ben-Sasson stated. “Now, the wand has turn out to be a lightsaber in your pocket, one thing anybody can wield, immediately, from your individual machine.”
In line with StarkWare, builders can construct with S-two, including that its alpha launch helps {hardware} targets. Moreover, the corporate stated ZK ecosystem contributors like Kakarot, Nexus, ZAN and AntChain OpenLabs have already adopted the know-how.
Kakarot makes use of S-two inside ETHProofs to generate Ethereum block proofs extra effectively, whereas Nexus is standardizing RISC-V traces to align with S-two’s structure. In the meantime, ZAN and AntChain OpenLabs are including GPU acceleration to push the prover’s efficiency even additional.
Use circumstances for S-two zero-knowledge prover
StarkWare chief working officer Oren Katz informed Cointelegraph that S-two marks a shift in how ZK-proofs are utilized in day by day lives. Producing validity proofs straight in units will enable privacy-preserving options in messaging, funds and digital identification.
“You’ll be able to show a fee was legitimate with out exhibiting your stability, or confirm identification with out revealing private particulars,” Katz added.
Katz stated that even wage funds may very well be made onchain with full transparency and no publicity of delicate data. He dubbed the event a “large step towards bringing zero-knowledge tech into the mainstream.”
Past privateness, Katz stated, native proof era additionally unlocks use circumstances in different industries. The chief informed Cointelegraph that it could actually enable players to play offline and later generate cryptographic proof of their achievements.
“An operator, as an alternative of working all logic onchain to show integrity, can run it on their very own servers and easily generate a proof that it was executed appropriately,” Katz added.

New ZK prover follows Ethereum’s privateness push
The launch of StarWare’s upgraded ZK prover follows Ethereum’s push for higher privateness. On April 11, Ethereum co-founder Vitalik Buterin revealed a roadmap that addressed privateness enhancements for wallets, decentralized finance (DeFi) functions and infrastructure.
Buterin advocated implementing privacy-enhancing norms and options throughout the Ethereum ecosystem, together with including privateness instruments in ETH wallets.
