Think PoUW might be one of the next crypto infra narratives ppl start waking up to.
Because AI compute demand, GPU economics and verifiable computation are finally starting to converge into something that makes sense.
The thesis now is that the same GPU can secure a chain while producing computation that someone outside crypto might actually pay for.
And block rewards can subsidize part of the compute cost, making decentralized inference cheaper than it otherwise would be.
A few projects are approaching this from completely different directions.
1/
@prlnet
– uses NoisyGEMM + ~60KB Plonky2 ZK proofs to verify GPU matrix multiplication
– independent measurement put network compute around ~24 exa-ops/s, equivalent to ~320K GPU-equivalents and ~112MW of power
–
@togethercompute launched a 31B-parameter Gemma inference endpoint with a 25%+ advertised discount, effectively using PRL mining rewards to subsidize AI compute
– RTX 5090 mining revenue fell from ~$33.80/day around launch to ~$17/day by late May, and has compressed further as difficulty increased
– announced a floating-point PoUW design targeting NVIDIA Blackwell with near-zero overhead over optimized vLLM inference
– FP8 support is being actively developed across Hopper/Blackwell-class hardware.
– partnered with Attestable around privacy-preserving proof-of-inference.
So Pearl probably has the largest raw PoUW compute footprint today, but real paid inference is still tiny relative to all that work.

@nockchain
– runs dual mining lanes: ZK-PoW using STARK proofs + AI-PoW using Pearl-compatible matrix/INT8 MAC computation
– current target is roughly 70% ZK / 30% AI, while the proposed Anthropos upgrade would flip this toward 30% ZK / 70% AI
– ~2–2.5 minute blocks, with the dual-puzzle setup running pretty stably since the Logos upgrade
– AI Compute Network peaked around ~19.6 ExaMAC/s in early September, roughly ~19.6K H100-equivalents at dense INT8
Longer term, NockVM + NockApps could turn Nock into a marketplace for arbitrary verifiable computation.

@ambient_xyz
– testnet is already live and serving real inference, not some late-2026 future launch
– reported 134B+ tokens served by June, with single-day peaks above 13B tokens and 100K+ monthly users
– OpenRouter integration + OpenAI/Anthropic-compatible API are already live, serving models including GLM and Kimi variants
– Proof-of-Logits checks just 1 randomly selected output token + progress markers instead of recomputing the whole inference
– claims around ~0.1% verification overhead, compared with materially higher overhead in Pearl's original matrix + ZK approach
4/
@gonka_ai
– PoW 2.0 focuses on processing real AI model requests instead of pure hashing
– clients submit inference jobs and GPU hosts compete to execute them
– reward pool starts around ~323K GNK per epoch, distributed by Proof-of-Compute weight with an exponential decay / roughly 4-year halving schedule
– supports model families including DeepSeek, MiniMax and GLM
5/
@dynexcoin
– DynexSolve combines mining with useful computational workloads around optimization, simulations, protein folding and other scientific tasks
– recent development seems increasingly focused on neuromorphic + quantum compute, including its Zeus architecture and room-temperature diamond-spin qubit work
– scientific workloads like optimization, molecular simulation and protein research could eventually become their own compute markets
6/
@quipnetwork
– architecture combines Ising-style optimization work for mining with a post-quantum asset-security layer
– optimization jobs can theoretically be solved using CPUs, GPUs, ASICs or quantum processors
– users submit computational problems with bids and miners compete to produce useful solutions
– positioning is basically a distributed "worldwide quantum computer" + post-quantum security network
There are also smaller experiments worth watching.
@Tensorcash wants every model inference to generate its own PoW certificate.
Arthur Hayes'
@flop_labs, which appeared in August around the idea of machines paying machines for GPU compute.
Overall, for PoUW to become a durable infra narrative, we need to see real fee flows, lower verification costs and some mechanism connecting customer spending back to token demand.
2026 is the first time the technical side looks credible enough to make this worth watching seriously.
Now it needs customers. If that part starts showing up, PoUW becomes a new market for compute.
Some smart ppl on my tl been bullish on #
DeSci# and PoUW narratives recently.
Spent some time digging deeper and I think DeSci x Proof of Useful Work (PoUW) might be one of the few setups where crypto actually pays for real output instead of just incentives.
Why?
PoUW is trying to turn energy + GPUs into useful output like AI training, molecular simulation, protein folding, ZK optimization, or biomedical research.
Right now, AI infra is eating capex. Big tech is racing for the best models, locking up GPU supply.
AI compute is scarce, expensive, and very real. But most workloads aren’t training frontier models.
They’re inference, fine-tuning, simulations, scientific compute… stuff that doesn’t need perfect clusters.
That kind of compute can run on fragmented, idle, or lower-tier GPUs.
So why is crypto still mostly paying people to farm points instead of paying networks to run useful workloads?
DeSci might be the first crypto-native buyer class that makes PoUW make sense.
Because DeSci needs compute, data, simulations, agents, and ways to fund research before TradFi even cares.
And this demand is continuous, not one-off.
Projects across the stack already point there:
–
@opentensor | $TAO → subnets compete to produce useful AI outputs, including scientific workloads.
–
@dynexcoin | $DNX → miners solve real-world optimization problems instead of hashing.
–
@gensynai | $AI → distributed training + verification layer.
–
@akashnet | $ASK → supply side of cheap, flexible GPU compute.
On the demand side:
–
@BioProtocol | $BIO → connecting researchers, funding, and compute.
–
@vitadao | $VITA → funding biotech research with onchain capital.
–
@Molecule_sci → turning research into IP that can be owned and licensed.
#
DeSci# is moving from DAO votes funding science into onchain research pipelines that can buy useful work repeatedly.
PoUW gives the supply side of useful compute.
DeSci gives the demand side that actually has a reason to buy it.
Scientific tasks get posted onchain with a budget, dataset, target metric, and validation requirements.
→ compute providers run the job offchain through decentralized GPU networks.
→ validators check results via redundancy, benchmarking, or verification layers.
→ payment settles only if output passes.
→ resulting value flows into datasets, models, or tokenized IP.
If this loop works:
– more research demand → more compute usage.
– more compute usage → better network efficiency.
– better efficiency → more real output.
– more output → stronger demand again.
If this thesis really plays out, DeSci x PoUW could become one of the first real demand loops in crypto.
Still early, infra not fully mature, verification remains a bottleneck.
But this is one of the few areas where I see:
– real users
– real workloads
– real value being created
