Cysic Announces Open Source FPGA Code to Enable Private Payments, Verifiable AI and Instant Gaming on Ethereum L2s
San Francisco, CA, June 26th, 2026, Chainwire
First public release of a complete FPGA implementation for zero‑knowledge proofs could finally make ZK‑rollups cheap enough for consumer‑scale applications.
A team of hardware and cryptography engineers at Cysic has released the first open-source, full-stack FPGA implementation of a zero-knowledge virtual machine (zkVM). The code, published today, is designed to accelerate the generation of ZK proofs; the cryptographic backbone of secure, private, and scalable blockchain networks.
If adopted by rollup operators and prover networks, the technology could dramatically lower the cost of ZK‑rollups, making them competitive on cost with optimistic rollups, which today are cheaper but settle more slowly and rest on different trust assumptions. That, in turn, would enable a new class of consumer applications that have remained theoretical for years: private stablecoin payments, portable identity without document uploads, verifiable AI on local devices, and on‑chain gaming with instant finality.
The Bottleneck That Held Back Web3
ZK‑rollups offer instant transaction finality and the same security guarantees as Ethereum mainnet. But generating the required cryptographic proofs has been computationally expensive; so expensive that most ZK‑rollups remain costlier than optimistic rollups, which require a seven‑day withdrawal window and weaker trust assumptions.
Consumers have voted with their wallets. They choose the cheaper, slower option. And many promising applications; like private payments, proof‑of‑age without revealing identity, and micropayments; have never reached scale because the underlying proof costs made them uneconomical.
What the Open‑Source Code Does
An FPGA (field‑programmable gate array) is a chip that can be reconfigured after manufacturing to perform a specific task extremely efficiently. For ZK proofs, a properly configured FPGA can run orders of magnitude faster and use far less power than a general‑purpose CPU or GPU.
Until now, FPGA implementations for ZK proving have stayed proprietary or locked to a single prover network. This release is the first complete, open-source FPGA proving stack for a full zkVM — the FPGA backend for Venus, Cysic’s open-source zkVM. It includes the complete proving pipeline, not just isolated primitives, and is licensed permissively for anyone to use, modify, or port to different hardware.
The code sits alongside a production GPU proving network that already generates proofs for Ethereum blocks. With both GPU and open FPGA backends, the infrastructure is no longer dependent on a single class of silicon; a reliability benefit for any application that relies on verifiable compute.
What Becomes Possible
With fast, cheap, and open ZK proving, several long‑promised consumer applications could finally move from white papers to wallets:
- Private, instant stablecoin payments – A business could prove its funds are clean without revealing its entire transaction history, at a cost of pennies instead of dollars.
- Portable, privacy‑preserving identity – A user could prove their age or creditworthiness in under a second, without uploading passports or sensitive documents to third‑party servers.
- Verifiable AI on consumer devices – An AI assistant on local hardware could prove it executed a given model faithfully on the user’s data — without sending that data to the cloud.
- On‑chain gaming with instant finality – A multiplayer game could settle hundreds of moves per second on a ZK‑rollup, with proof costs low enough to make true asset ownership practical.
- Micropayments and streaming money – Paying a fraction of a cent per second for video or API calls would no longer be eaten by fees, because per‑transaction proofs would become nearly free.
Availability
The open‑source FPGA code is available today on GitHub under permissive licenses. It is under active development and not yet audited for production use, but the team has invited researchers, developers, and hardware engineers to study, test, and build upon it.
“ZK only reaches its potential when proving is fast, cheap, and verifiable by anyone. Open‑sourcing the first FPGA zkVM is our way of saying the ecosystem moves forward together – not behind closed doors.” — Leo Fan, CEO of Cysic
