Zero-Knowledge Proving on Edge, Mobile and IoT Devices
Zero-knowledge proving leaves the datacenter.
Phones, gateways and IoT sensors can't carry gigabyte-scale prover footprints. A constant, megabyte-scale memory budget moves proving and verification onto the hardware where private data already lives.

Edge hardware is a memory problem, not a branding exercise.
Conventional ZK provers materialize the full witness in RAM. Peak memory climbs with circuit size — fine in a datacenter, fatal on a phone or sensor. Teams that want on-device privacy hit OOM long before they hit a product launch.
The shift isn't theoretical cryptography. It's memory engineering: a footprint small enough to plan around, flat enough to deploy anywhere.
Proving and verifying on constrained hardware.
On-device proving
The prover processes the witness and outputs a proof. Memory-bound — this is where streaming infrastructure matters. Snark Stream holds a bounded working set instead of scaling with circuit size.
Snark StreamOn-device verification
A compact verifier checks a proof in milliseconds inside an app, wallet or firmware image. Lighter than proving, but still sensitive to binary size and RAM on embedded targets.

Mobile wallets
Prove locally before signing a transaction. Private inputs never leave the handset — only the proof does.
IoT attestation
Sensor readings and firmware integrity proved on-device before telemetry leaves a constrained gateway.
Edge gateways
Prove during a brief connectivity window on a box with a hard RAM cap — no datacenter dependency.
Offline-first apps
Generate a proof without network access; verify or submit when connectivity returns.
Honest limits, designable budgets.
Not every circuit runs on a microcontroller tomorrow. Profile your workload, set a memory ceiling, and choose infrastructure that holds it flat as proofs grow.
Memory infrastructure, not a mobile SDK pitch.
zkmem builds the layer beneath your circuits and frameworks — bounded proving via Snark Stream, predictable allocation via ZK Alloc. Same stack from CI to handset.
Edge & mobile ZK, answered.
Yes — when peak memory is bounded. Conventional provers scale RAM with circuit size and OOM on handsets. Snark Stream keeps a constant working set (~120 MB), which is within reach of modern phones and edge hardware for many production circuits.
Verification is typically lighter — a small verifier checks a proof in milliseconds. Proving is heavier because the prover must process the witness. Both benefit from a tight memory budget, but proving is where teams hit OOM first without streaming infrastructure.
Proving and verification can run without a server round-trip once the prover or verifier is on the device. Witness data and private inputs stay local; only the finished proof needs to travel when you choose to submit it.
Most edge and mobile proving workloads start with Snark Stream — it bounds peak RAM regardless of circuit size. If allocator overhead and heap fragmentation are your bottleneck, ZK Alloc complements it on the proving hot path. Many deployments use both.
