[ANN] PearlVolt - Fastest CUDA Miner for Pearl (PRL)

WHAT IS PEARLVOLT?

PearlVolt is a CUDA-native GPU miner for the Pearl (PRL) network — a Proof-of-Useful-Work L1 where mining hashpower runs verifiable matrix computation instead of wasting energy on SHA-256 preimages.

One static binary. No CUDA toolkit, no Python, no dependencies. Download, verify SHA-256, run.

Anonymous mining — no registration needed
Min payout: 0.10 PRL, paid every 2 hours
Pool fee: 0.9% (PPLNS)
Dev fee: 3% (transparently logged in telemetry stream)

Works with ANY PRL pool — just change the --pool flag. PearlVolt is compatible with all standard stratum endpoints: pearlhash.xyz, kryptex.com, herominers.com, luckypool.io, etc.

FEATURES

1. Auto-tuned CUDA kernels
Kernels re-tune per GPU architecture at launch — occupancy, register pressure, memory clocks profiled live. A 5090 and a 3090 each run their own optimum without config.

2. 3% dev fee
Flat 3%, mined transparently and logged. No hidden second wallet, no fee spikes. Verify in telemetry at any time.

3. Failover & watchdog
Define a pool list; PearlVolt fails over on stratum drop in under a second. Auto-restarts hung GPUs without taking down the rig.

4. Telemetry API
Local :4141/metrics Prometheus endpoint + JSON socket. Hashrate, shares, temps, power — ready for Grafana on day one.

5. TLS stratum support
--tls flag. Wallet address and share data never travel cleartext. Compatible with all standard stratum proxies.

6. Variable difficulty
Pool-side vardiff adjusts every 60s based on hashrate. No stale shares from too-hard targets, no spam from too-easy ones.

7. Per-GPU control
--gpus 0,2,4 to mine on specific cards. Mix and match any GPUs.

8. Multi-GPU display
ANSI-colored per-GPU table: hashrate, temp, power, fan, shares. Refreshes every 3s. Works with 1-8 GPUs.

WHY PEARLVOLT IS FASTER

PearlHash is a GEMM-based Proof-of-Useful-Work algorithm. The mining kernel runs real matrix multiplication (A × B) and commits to the output as proof. PearlVolt's kernel is hand-tuned CUDA with:

Architecture-specific warp scheduling (sm_80/86/89/90/120)
mma.m16n8k32 tensor core instructions (Ampere through Blackwell)
Launch bounds optimized per SM count (2 blocks/SM on sm_89/120, 3 blocks/SM on sm_90+)
Register pressure tuned to maximize occupancy without spills
fp16 noising for PoW commitment with zero overhead on GEMM path
R=64 GEMM tile size (proven optimal across architectures)
Async Merkle tree build (64MB, 65,536 BLAKE3 leaves) — CPU proof creation runs in background, GPU never stalls
Async header updates — A matrix rebuilt on pool job change without blocking the mining loop

Result: 395 TH/s on a single RTX 5090 at 600W. That's 658 GH/W — the highest efficiency of any PRL miner.

PROOF OF USEFUL WORK — WHY PRL IS DIFFERENT

Bitcoin mining burns energy on SHA-256 preimage hunts — pure waste. Pearl's PearlHash runs verifiable matrix multiplication. The same computation that secures the network could power AI inference workloads.

1. COMPUTE — GPU runs the PearlHash kernel (real GEMM)
2. VERIFY — Block proof checked on-chain via zk-powered validation
3. EARN — Valid blocks earn 2,500 PRL, distributed via PPLNS

No trusted hardware. No hand-waving. The work is real or the block doesn't exist. Pearl is the only L1 where mining hashpower does real verifiable work.

FAQ

Q: Which GPUs are supported?
A: Any NVIDIA GPU with compute capability 8.0+ (RTX 30 series and newer). AMD support is not planned — PearlHash is CUDA-optimized GEMM.

Q: Do I need to register?
A: No. Anonymous mining. Just pass your PRL wallet address.

Q: What are the fees?
A: 3% dev fee (mined transparently, logged in telemetry) + 0.9% pool fee on PearlVolt pool. Solo mode: 3% dev fee, 0% pool fee. You can also mine to ANY other PRL pool — only the 3% dev fee applies.

Q: Can I solo mine?
A: Yes. --pool stratum+tcp://pool.pearlvolt.run:4143 (0% pool fee)

Q: Is there a TLS option?
A: Yes. --pool stratum+tls://pool.pearlvolt.run:4142

Q: How are payouts calculated?
A: PPLNS (Pay Per Last N Shares). Your share of the work, transparently accounted. Min payout 0.10 PRL, paid every 2 hours.

Q: How is Pearl different from Bitcoin mining?
A: Bitcoin wastes energy on SHA-256 preimage hunts. Pearl's PearlHash runs verifiable matrix multiplication — the same computation that powers AI workloads. Proof-of-Useful-Work, not proof-of-waste.

Q: Can I use PearlVolt with other PRL pools?
A: Yes. PearlVolt speaks standard stratum. Change --pool to point at any PRL pool: pearlhash.xyz, kryptex.com, herominers.com, etc. The 3% dev fee applies regardless of which pool you use.

Q: How do I verify the dev fee is only 3%?
A: Watch the telemetry stream at localhost:4141. Dev fee shares are logged with a separate worker name. Total dev fee time = 3% of runtime, transparently visible.

DISCLAIMER
Mining cryptocurrency involves risk. PRL price, network difficulty, and reward structures can change. Calculate your own profitability based on your electricity cost, GPU efficiency, and current PRL price. This is not financial advice. Mine responsibly.

If you found this useful, consider mining to the PearlVolt pool. Every rig strengthens the network and earns PRL.

Happy mining.
