GPU compute, settled the instant it's done.
Idle GPUs matched to real jobs, paid per interval through a self-expiring Kaspa covenant. No validators. No custody. No seven-day payout cycle.
A general-purpose settlement layer for parallel GPU work — starting with image rendering and neuroscience research training.
Type a prompt, pay a little KAS, watch a real GPU render it.
Not a mockup — a testnet wallet, a real on-chain covenant, a live fleet GPU rendering your prompt. The image lands right here.
Step 1 — Connect a testnet wallet
Kasperia or KASware, set to Testnet-10. No mainnet funds are ever touched here.
Escrow that pays as work happens, not after.
Every session is an on-chain covenant. The deposit only moves toward the provider as work completes — or back to the renter if it doesn't.
Match
Jobs go to the best available node by measured benchmark — real throughput, not a self-reported spec sheet.
Escrow opens
A Toccata covenant locks the renter's deposit on-chain. Both keys — renter and provider — are needed to move funds forward.
Settle per interval
Each claim pays the provider's running total and rolls the deadline forward. If either side goes dark, the renter reclaims the balance automatically.
Same idea as an eBay purchase — escrow, release on delivery, auto-refund on timeout — but enforced by Toccata covenants native to Kaspa L1, not a company. The self-custody guarantee Bitcoin vaults pioneered. All three settlement paths — per-interval claim, final settle, timeout refund — proven live on Testnet-10 on a real 3-node fleet (RTX 5080 / 3070 Ti / 3070).
One settlement engine, many kinds of work.
The same on-chain settlement — match, escrow, per-interval payout, spot-check audit — works for any GPU job that splits into independent pieces.
Image rendering
Stable Diffusion image generation. Live since July 2026 — the one-click demo above.
Neuroscience research training
GPU-parallel spiking-neuron training sweeps, based on the Tempotron model (Gütig & Sompolinsky, 2006). Live since July 2026.
Every job type carries its own verification — perceptual similarity for images, exact-match determinism for training sweeps. A spot-checked result that doesn't match is withheld, not paid.
Turn a spare GPU into a KAS-earning node.
One binary on the machine you already have. No license fee, no proprietary SDK, no Kubernetes.
- → Measured benchmark, not self-reported specs — your GPU's real throughput sets your match priority.
- → Paid per interval in KAS, straight to your own wallet — never pooled, never held longer than one claim cycle.
- → Windows, Linux — close the window any time and go offline with zero penalty.
Sub-second blocks and native covenants, secured by proof-of-work.
Kaspa is a PoW BlockDAG with ~1-second blocks and self-expiring covenants at the base layer — so a rental settles on-chain the instant work finishes, with no validator set to trust.
| Network | Settlement model | Payout cadence | Trust assumption |
|---|---|---|---|
| KudaCash | On-chain covenant, per interval | ~1 sec, self-expiring | None — PoW-secured, no validator set |
| Akash | Account-model escrow | ~6 sec blocks, hard overdraw cliff | Cosmos validator set |
| Render Network | Task-level, batched | Every 7–10 days | Ethereum + proprietary renderer license |
Look up any KAS address on the network.
Paste a renter or provider address to see deposits, completions, and running totals. Read-only data is public — a wallet is only needed to move funds.
This is a live pilot, running today.
Real nodes, real covenants, real KAS moving on testnet-10 — the pay-and-render demo above is live, not a waitlist screenshot.
