Your phone already has a GPU.
We should be using it to protect your privacy.
Today we’re sharing PSE’s roadmap for client-side GPU acceleration, making zero-knowledge proofs and post-quantum crypto fast enough to run on your own device, not on servers that see all your data.
👉🏻 See threads for link and summary
2/ Why client-side GPU matters:
Most “private” apps still do heavy cryptography on servers. That means someone else sees your inputs. Real privacy = proving locally, on your own device. The missing piece has always been performance.
3/ The hard truth:
Zero-knowledge proofs and post-quantum cryptography are computationally heavy. CPUs alone make them too slow for everyday use. That’s why client-side proving hasn’t taken off until now.
4/ The insight is simple:
Every modern phone and laptop already has a powerful GPU. GPUs excel at the kind of parallel computation that modern cryptography needs. We just haven’t built the right libraries to use them yet.
5/ Our approach at PSE:
- Build community-owned GPU crypto libraries
- Designed for zero-knowledge, privacy, and post-quantum security from day one
- Start with native GPU APIs (like Metal), then expand to WebGPU for broader adoption Think “Arkworks for GPUs”.
6/ This work is also part of @ethereumfdn’s broader push for quantum readiness.
Post-quantum primitives are compute-heavy, but surprisingly well-suited for GPUs. For example, 31-bit field operations map almost perfectly onto 32-bit GPU architectures.
@drakefjustin on EF's PQ security priority:
Jan 24, 04:05
Today marks an inflection in the Ethereum Foundation's long-term quantum strategy.
We've formed a new Post Quantum (PQ) team, led by the brilliant Thomas Coratger (@tcoratger). Joining him is Emile, one of the world-class talents behind leanVM. leanVM is the cryptographic cornerstone of our entire post-quantum strategy.
After years of quiet R&D, EF management has officially declared PQ security a top strategic priority. Our journey began in 2019, with the "Eth3.0 Quantum Security" presentation at StarkWare Sessions. Since 2024, PQ has been central to the @leanEthereum vision. The pace of PQ engineering breakthroughs since then has been nothing short of phenomenal.
It's now 2026, timelines are accelerating. Time to go full PQ:
→ PQ ACD: Antonio Sanso (@asanso) kicks off a bi-weekly All Core Devs PQ transactions breakout call next month. These sessions focus on user-facing security, covering dedicated precompiles, account abstraction, and longer-term transaction signature aggregation with leanVM.
→ PQ foundations: Today we are announcing a $1M Poseidon Prize to harden the Poseidon hash function. We are betting big on hash-based cryptography to enjoy the strongest and leanest cryptographic foundations. Check out our other $1M PQ initiative, the Proximity Prize.
→ PQ devnets: Multi-client PQ consensus devnets are live! Shoutout to pioneers @zeamETH, @ReamLabs, @PierTwo_com, @geanclient, @ethlambda_lean, as well as established consensus teams Lighthouse, Grandine, and soon Prysm. This incredible teamwork is coordinated by @corcoranwill via weekly PQ interop calls.
→ PQ workshops: Building on last year's PQ workshop in Cambridge (see photo), the EF is hosting another 3-day PQ event in October. Top experts from around the world will convene. In addition, a PQ day is set for March 29 in Cannes just ahead of EthCC.
→ PQ FV and AI: Last week Alex Hicks (@alexanderlhicks) ran a specialised maths AI for 8 hours, at a $200 cost. It one-shotted a formal proof one of the hardest lemmas in the foundations of hash-based snarks. Mind-blowing. Applied cryptography will never be the same.
→ PQ roadmap: A comprehensive breakdown of the EF's proposed PQ strategy will be shared soon™ on pq[.]ethereum[.]org. The roadmap targets a full transition in coming years with zero loss of funds and zero downtime. Stay tuned :)
→ PQ education: The ZKPodcast (@zeroknowledgefm) is producing a 6-part video series on Ethereum's PQ strategy. EF Enterprise Acceleration is also preparing material for enterprises and nation-states. Finally, Ethereum is now represented on the PQ advisory board that Coinbase announced yesterday.
Believe in something. Believe in PQ security.
7/ The goal isn’t just faster proofs.
These GPU libraries can benefit:
- Zero-knowledge systems
- Fully homomorphic encryption (FHE)
- Privacy-preserving applications across Ethereum and beyond Open, reusable, and built for the long term.
