Zero-knowledge infrastructure firm Cysic is integrating with the Succinct Prover Network to bolster real-time ZK proving capabilities, the company announced Thursday.

Cysic, which offers a Layer 1 network for zero-knowledge proof generation and verification, will join Succinct as a multi-node prover. As part of the move, it's deploying a GPU cluster designed to support high-volume, production-grade workloads — a key step toward addressing growing demand for ZK applications across sectors.

"ZK is expanding beyond crypto and into the real world," stated Cysic co-founder Leo Fan in a release shared with The Block. "Institutions are starting to realise the importance of zero-knowledge proving, and keeping that momentum demands reliable, institutional-grade infrastructure."

As use cases like ZK-powered age verification roll out via platforms such as Google Wallet, infrastructure players are under pressure to scale fast.

The Succinct Prover Network operates as a decentralized marketplace for ZK proof generation. It coordinates requests through its SP1 zkVM, an open-source virtual machine optimized for proving. Cysic will contribute its vertically integrated stack — including a ZK-specialized ASIC chip clocking 1.33 million Keccak functions per second — to boost performance across the network, according to the release.

Succinct CTO John Guibas said onboarding Cysic "reflects the growing momentum" around decentralized ZK systems. Cysic's testnet, now in its final phase, has attracted over 118,000 provers and 200,000 verifiers.

Cysic was founded in August 2022 and raised $6 million in a February 2023 seed round led by Polychain Capital.
