Pearl (PRL) · Proof-of-Useful-Work

Mine PRL and sell the inference from the same GPU.

The first Pearl pool where your mining compute is real AI inference — so you earn coins and a share of paid inference revenue. One GPU, two income streams.

Why Linkrra Pearl Pool

Pearl mining is matrix multiplication — the same math that runs every LLM. We're the pool that turns it into sellable inference.

Dual income

Your H100/H200 mines PRL while serving real paid inference — two revenue streams from one GPU-hour. Proven end-to-end on live hardware.

Built safe

Idempotent, crash-proof ledger — no double-pays, ever. Independent security audit before any real payout. Your earnings are accounted to the satoshi.

Every card welcome

Datacenter H100/H200 via our inference gateway; consumer 3090/4090/5090 via standard stratum. The whole swarm, one pool.

Supported GPUs & hashrate

Measured PRL throughput per card. Higher-tier cards (H100/H200) also unlock the inference revenue tier.
