In Ethereum’s scaling landscape, where ZK rollups promise cryptographic batching of thousands of transactions into succinct proofs, the real hurdle has always been proof generation speed. General-purpose CPUs and GPUs strain under the elliptic curve operations and finite field arithmetic required for protocols like Groth16 or Plonky3. Cysic’s ZK C1 chip upends this dynamic, delivering a zkVM-based ASIC tailored for ZK rollup hardware acceleration that benchmarks show can churn through 1.3 million Keccak hashes per second – over 100 times faster than prior software baselines.
This isn’t mere hype from a newcomer. Founded in August 2022 and backed by $6 million in seed funding by early 2023, Cysic has methodically built a stack blending custom silicon with a distributed prover network. Their C1 chip hardwires the repetitive finite field multiplications and hash permutations that dominate ZK workloads, sidestepping the inefficiencies of von Neumann architectures. Early adopters like Scroll already leverage Cysic’s acceleration for their Layer 2 proofs, while integrations with Succinct’s prover network underscore the chip’s production readiness.
Cysic C1 Chip Architecture: Built for ZK Primitives
At its core, the C1 chip embodies a programmable zkVM accelerator with native instructions for prime-field arithmetic – the lifeblood of SNARK/STARK constructions. Unlike GPUs that parallelize broadly but waste cycles on non-ZK tasks, the C1 dedicates pipelines to Keccak-256 (Ethereum’s hashing standard) and BLAKE2, alongside high-bandwidth internal memory to feed these units without bottlenecks. Cysic’s design philosophy prioritizes flexibility: developers can compile zkVM circuits directly onto the chip, supporting diverse backends from Halo2 to RISC Zero.
This hardware specificity yields outsized gains. Benchmarks from late 2024 reveal the C1 sustaining peak throughput on hash-heavy circuits, critical for rollup state commitments. For context, a single C1-equipped node outpaces clusters of high-end NVIDIA A100s in raw ZK proving cycles per second, per independent tests. Yet Cysic tempers enthusiasm with realism: while ASICs excel on fixed workloads, their zkVM layer ensures adaptability as proof systems evolve toward post-quantum variants.

Benchmarks and Partnerships Driving Real-Time Proving
Cysic’s claims hold under scrutiny. Independent analyses confirm the C1’s 1.3 million hashes per second, translating to sub-second proofs for modest rollup batches – a far cry from the minutes-long delays plaguing software provers. This positions Cysic as a linchpin in Ethereum’s roadmap toward real-time ZK, where proofs settle on-chain without aggregation delays. Their GPU-accelerated libraries for Plonky2, Halo2, Gnark, and Raptor’s RapidSnark further bridge the gap, outperforming open-source CUDA implementations across AMD and NVIDIA cards.
Strategic alliances amplify impact. Cysic joined Succinct’s Prover Network as a multi-node operator, handling production ZK rollup workloads with GPU clusters augmented by C1 prototypes. A collaboration with Polyhedra integrates the Expander backend onto C1 hardware, targeting BLAKE2/Keccak acceleration for quantum-resistant proofs while slashing power draw. These moves aren’t isolated; they align with broader ZK infrastructure plays, from Brevis rivals to DePIN prover markets. For more on this trajectory, see how zero-knowledge proof hardware acceleration is revolutionizing ZK rollup scalability.
ZK Air and ZK Pro: Hardware Products for 2025 Rollouts
Cysic isn’t stopping at silicon. In 2025, they unveil ZK Air – a pocket-sized accelerator akin to an iPad charger, primed for developer laptops and edge verification. Plug it in, and it offloads lightweight ZK tasks, democratizing access to ZK proving hardware beyond data centers. Complementing this, ZK Pro fuses multiple C1 chips with front-end modules for hyperscale zkRollups and zkML inference, eyeing workloads that demand millions of proofs daily.
These products address a market gap: while software provers scale linearly with cores, hardware like C1 offers quadratic efficiency on ZK ops. Cysic’s roadmap hints at ecosystem expansion, potentially powering bridges, coprocessors, and even consumer dApps. Investors note the parallels to early FPGA booms in Bitcoin mining – will Cysic spark a ZK ASIC arms race? Early signals from Scroll’s efficiency gains suggest yes, but sustained benchmarks against rivals like ZKValid will dictate longevity.
That longevity question hinges on Cysic’s ability to navigate a crowded field of ZK accelerators. Rivals like ZKValid and Brevis tout software-centric approaches, but Cysic’s ASIC edge shines in sustained throughput for Ethereum L2 proving speed. A head-to-head from Mitosis University benchmarks underscores this: Cysic nodes prove rollup batches 3-5x faster than GPU clusters under load, thanks to hardcoded finite field ops that GPUs approximate via shaders. Yet software flexibility remains a counterpoint – can Cysic’s zkVM keep pace with recursive proof innovations like those in SP1?
Competitive Edge: C1 vs. the ZK Hardware Landscape
Cysic differentiates through vertical integration. While others lease cloud GPUs, Cysic owns the silicon stack, from C1 design to prover network ops. Their GPU libraries – optimized for Plonky2 and Halo2 – serve as a stopgap, delivering 2x gains over vanilla CUDA on A100s without custom kernels. This hybrid model lowers entry barriers: developers test on GPUs, deploy to C1 for scale. Partnerships like Succinct embed Cysic clusters directly into decentralized proving markets, where latency wins bids.
Cysic C1 Benchmarks vs. GPU/CPU
| Hardware | Keccak Hashes/sec | Proof Time (1k tx batch) | Power Efficiency (hashes/s/W) |
|---|---|---|---|
| Cysic C1 | 1.3M | 1 s | 17k |
| NVIDIA A100 GPU | 130k | 10 s | 325 |
| CPU Baseline | 13k | 100 s | 52 |
Power efficiency merits scrutiny too. ZK proving guzzles watts – a single rollup proof can rival household appliances. Cysic’s Polyhedra tie-in cuts hash draw by 40%, per joint tests, aligning with Ethereum’s sustainability push post-Dencun. For fast ZK rollups Cysic enables, this matters: data centers running C1 fleets could halve Ethereum L2 energy footprints, bolstering DePIN economics.

Economic Implications for Rollup Operators
Operators face stark choices. Software provers scale with AWS bills; Cysic hardware amortizes over workloads. A mid-tier rollup sequencing 10k tx/day might shave $50k monthly via C1 offload, based on Scroll’s reported gains. This shifts incentives: L2s prioritize ZK-native chains, favoring hardware provers in aggregator races. Cysic’s DePIN layer – rewarding node uptime with fees – mirrors Helium’s model, potentially tokenizing proof capacity.
Risks loom, however. ASIC rigidity could falter if Ethereum pivots to lattice-based ZK post-quantum. Supply chain snarls, as seen in 2023 chip shortages, threaten 2025 rollouts. Cysic counters with ZK Air’s modularity, letting devs iterate sans fab delays. Still, adoption lags without audited circuits; independent verifies from Cryptology ePrint affirm C1’s soundness, but real-world audits for Expander await.
Zooming out, Cysic embodies ZK’s hardware inflection. Ethereum’s rollups, once bottlenecked by prover latency, edge toward real-time settlement. C1 chips in ZK Pro racks could prove gigabyte state diffs in seconds, unlocking consumer apps from DeFi to gaming. As Succinct and Polyhedra integrations mature, expect Cysic nodes dotting global data centers, fueling a proving economy worth billions. For deeper context on this shift, explore how hardware acceleration is making ZK rollups usable for blockchain scalability in 2025.
The C1’s trajectory tests a thesis: specialized silicon trumps generality in crypto primitives. If Cysic delivers on ZK Air shipments and Pro scalability, Ethereum L2s gain a proving powerhouse. Operators watching Scroll’s metrics will decide – but the benchmarks don’t lie. Hardware acceleration isn’t coming; it’s here, rewiring ZK rollups from promise to production.
