Quick Take
Succinct has announced the SP1 Hypercube, a next-generation zkVM designed for real-time Ethereum proving.Real-time proving is vital for Ethereum’s roadmap, helping to scale the network without sacrificing decentralization.

 blocks in under 12 seconds, crossing a milestone in the race for real-time proving.

Real-time proving is key to Ethereum's scaling roadmap, boosting Layer 1 throughput, native rollup security, and interoperability without compromising verifiability or decentralization. During internal tests on 10,000 Ethereum mainnet blocks, the system proved 93% of blocks in real time using a cluster of 200 Nvidia RTX 4090 GPUs, with an average proving time of just 10.3 seconds, the team said in a statement shared with The Block.
"Real-time proving is a massive unlock for Ethereum — for three key reasons," Ethereum Foundation researcher Justin Drake commented on the broader significance of the tech. "First, it enables us to scale the Layer 1 using ZK validators and ZK execution clients. Second, it allows for more secure rollups that don't rely on multisigs or governance — what we call native rollups. And third, it opens the door to shared sequencing and synchronous composability, paving the way for a more unified Ethereum — where network effects at the Layer 1 can scale across the entire ecosystem, including its Layer 2s."

Competing with high-throughput chains
Competing with high-throughput chains like Solana often means raising hardware demands on Ethereum's Layer 1, which can push out home validators, the team explained. Succinct says zero-knowledge proofs avoid this by offloading heavy computation to a smaller number of provers — systems that execute the full process and generate cryptographic proofs showing it was done correctly, without revealing the underlying data — allowing validators to verify the result quickly without redoing the work.

Real-time proving is the space race of zero knowledge, a technical and symbolic breakthrough that once felt out of reach," Succinct co-founder and CTO John Guibas said. "A year ago, this was seen as science fiction. Today, it's open source and generates Ethereum proofs in under 12 seconds. It's our four-minute mile for ZK."
In a live demo, Succinct proved Ethereum block 22309250 — containing 143 transactions and consuming 32 million gas — in just 10.8 seconds, generating a 1MB proof in real time. While several teams, including RISC0, Snarkify, and Kakarot, have been actively working toward this goal, Succinct says it's the first to reach "real-time" sub-12 second speeds.
"Achieving real-time proving required architectural changes at every level of the stack," Succinct Head of Cryptography Ron Rothblum said. "SP1 Hypercube parallelizes over 600 million RISC-V cycles per block across a purpose-built GPU cluster, coordinated with custom infrastructure designed for latency and fault-tolerance."
Succinct has open-sourced the SP1 Hypercube verifier and Ethereum prover code, with full deployment planned after an upcoming audit. The company estimates a real-time prover cluster could eventually be built for as little as $100,000 using optimized hardware, making it feasible for broader adoption across Ethereum infrastructure and new zk-based applications.
Earlier on Tuesday, Succinct announced it will launch PROVE as the native token of its prover network — a decentralized protocol on Ethereum for zero-knowledge proofs. In 2024, Succinct Labs, the project's core developer, raised $55 million in a Series A funding round led by Paradigm.

Cysic, a leading zero-knowledge (ZK) infrastructure firm, has announced its integration with the Succinct Prover Network, further enhancing real-time proving capabilities for blockchain and beyond.

Expanding the Prover Marketplace

The Succinct Prover Network is a decentralized marketplace for ZK proof generation, where proof requests are matched with provers that can efficiently deliver results. By joining as a multi-node prover, Cysic will bring both hardware and software optimizations to strengthen the ecosystem.

This move reflects the growing demand for scalable, production-grade zero-knowledge infrastructure, as applications expand from crypto-native use cases into broader industries.

Cysic’s Role: High-Performance ZK Proving

Cysic operates a Layer 1 network dedicated to ZK proof generation and verification. Its integration with Succinct introduces several performance advantages:

GPU Cluster Deployment – Designed to handle high-volume workloads for real-time proving.

ZK-Specialized ASIC – Capable of processing 1.33 million Keccak functions per second, significantly boosting throughput.

Vertically Integrated Stack – Hardware and software alignment ensures optimized efficiency.

This combination of infrastructure is critical as demand for ZK-powered applications scales, from DeFi privacy tools to identity verification and cross-chain security systems.

The Institutional Push for Zero-Knowledge

Cysic co-founder Leo Fan emphasized that zero-knowledge cryptography is no longer confined to blockchain circles.

“ZK is expanding beyond crypto and into the real world. Institutions are starting to realise the importance of zero-knowledge proving, and keeping that momentum demands reliable, institutional-grade infrastructure,” Fan stated.

Recent pilots, such as ZK-powered age verification through Google Wallet, highlight how mainstream applications are beginning to adopt this technology. With this momentum, infrastructure providers must scale quickly to meet institutional-grade requirements.

Strengthening Succinct’s SP1 zkVM

Succinct coordinates proof generation through its SP1 zkVM, an open-source virtual machine optimized for ZK proving. By joining the network, Cysic will help accelerate proof generation and broaden the range of workloads the system can support.

Succinct CTO John Guibas described the integration as evidence of growing momentum around decentralized ZK infrastructure:

“Onboarding Cysic reflects the growing momentum around decentralized ZK systems.”

Community Growth and Adoption

Cysic’s own network has already demonstrated strong traction, with its testnet attracting:

118,000+ provers

200,000+ verifiers

This community momentum provides a solid foundation as Cysic contributes its infrastructure to Succinct’s prover network.

Background: Funding and Development

Founded in August 2022, Cysic has quickly established itself as a key player in ZK infrastructure. In February 2023, it raised $6 million in a seed round led by Polychain Capital, enabling rapid development of its hardware and network solutions.

With its integration into Succinct, Cysic is positioning itself at the forefront of decentralized zero-knowledge systems.

Final Takeaway

The partnership between Cysic and Succinct highlights a critical step toward making zero-knowledge proofs scalable, decentralized, and institutional-grade. By combining Cysic’s hardware acceleration with Succinct’s decentralized marketplace model, the ecosystem gains the ability to support real-world ZK applications at scale.

As adoption expands into areas like finance, identity verification, AI, and cross-chain security, the need for such high-performance infrastructure will only grow. With Cysic’s integration, the Succinct Prover Network takes another step toward becoming a cornerstone of the global ZK economy.
