Zero-knowledge memory infrastructure for low-memory ZK proving
Zero-knowledge proving in a fraction of the RAM.
zkmem builds the memory layer that keeps ZK provers small and predictable — a streaming prover that never OOMs and a ZK-native allocator that eliminates hot-path fragmentation.
- ~120 MB
- Constant footprint
- O(1)
- Peak vs. circuit size
- 0
- OOM failures
Peak memory that never grows.
A conventional prover materializes the whole witness at once, so resident memory climbs with circuit size until it overruns the machine. Snark Stream holds a fixed working set — the ceiling is flat, and it stays flat from the first proof to the largest one you will ever run.
- Capacity you can plan around — proof after proof.
- The same binary runs in CI, in a container, or on a handset.
- No tuning, no swap thrash, no surprise OOM at 3 a.m.
grows with the witness → overruns the machine
constant ceiling → independent of circuit size
ZK proving has a memory problem.
Generating a zero-knowledge proof is one of the most memory-intensive operations in modern cryptography. As circuits grow, so does the RAM the prover needs — until it doesn't fit.
Peak memory explodes
Provers materialize the full witness and intermediate polynomials at once, so RAM scales with circuit size and large proofs OOM.
Allocator thrash
Frameworks fire millions of malloc/free calls per proof, fragmenting the heap and stalling on the global allocator.
Oversized hardware
Teams overprovision expensive high-memory machines just to keep proving alive — and still hit ceilings.
No path to the edge
Memory pressure keeps proving confined to the datacenter, out of reach for mobile and edge devices.
Two memory solutions, built for ZK.
Purpose-built infrastructure that attacks the memory problem from two directions — how proofs are processed, and how memory is allocated.
Infrastructure-grade, not a research demo.
We work at the level where memory actually behaves — streams, arenas, allocators and cache lines — so your proving stack gets predictable, production memory characteristics.
Bounded & predictable
Memory ceilings you can plan capacity around, proof after proof.
Drop-in integration
Works with your existing circuits and frameworks — no rewrites.
Built for the hot path
Optimized where proving spends its time, not just on benchmarks.
Prove and verify on phones, edge nodes and IoT devices.
A constant, megabyte-scale memory footprint changes where zero-knowledge can run. With Snark Stream's bounded working set and ZK Alloc's deterministic arenas, proving and verification leave the datacenter and move onto the hardware in people's hands — and the sensors at the edge of the network. Sensitive inputs stay local; only the proof travels.
On-device proving
Generate proofs locally on a phone, laptop or edge node. Private inputs never leave the hardware — only the finished proof does.
On-device verification
Verify proofs in milliseconds inside mobile apps, wallets and embedded firmware with a small, auditable verifier.
IoT & embedded
Run attestation and integrity proofs on microcontroller-class hardware, where every kilobyte of RAM is accounted for.
Mobile-first privacy
Power identity, location and payment proofs that keep sensitive data on the handset instead of a remote server.
From rollups to the edge.
When proving fits in a constant, small memory budget, it can run almost anywhere your workload needs it to.
Zero-knowledge memory, explained.
It is the layer of software that controls how a zero-knowledge prover uses RAM. ZK proving is memory-bound — peak memory, allocation patterns and fragmentation decide whether a proof runs at all. zkmem builds that layer: Snark Stream and ZK Alloc make proving fit in far less memory.
Snark Stream restructures proving as a streaming pipeline, processing the witness in ordered chunks so resident memory stays at a constant ceiling (~120 MB) instead of scaling with circuit size. ZK Alloc replaces millions of malloc/free calls with a three-region arena allocator, removing fragmentation and allocator overhead on the proving hot path.
Yes. Because Snark Stream keeps a bounded working set, peak memory no longer grows with proof size — the primary cause of OOM during proving. Proving that previously needed many gigabytes can run on commodity CI runners, containers and edge devices.
Yes. A constant, megabyte-scale memory footprint is exactly what edge, mobile and embedded hardware needs. With Snark Stream's bounded memory profile, proving and verification that were confined to large servers become feasible on phones, edge nodes and microcontroller-class IoT devices — keeping private inputs on the device.
No. Both solutions are designed to integrate with existing proving flows. Snark Stream slots into your current pipeline without changing circuits or the trusted setup, and ZK Alloc operates at the allocation layer beneath your framework.
