Pearl (PRL) · Proof-of-Useful-Work

Mine PRL and sell the inference from the same GPU.

The Pearl pool that supports both dedicated mining (PRL rewards) and inference serving. Measured: inference at $0.107/1M output tokens on H100. Mining and inference are separate workloads — a GPU does one or the other.

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.

Inference pricing

Measured on H100 NVL: $0.107/1M output tokens (Qwen3-30B-A3B, c=256). Competitive with Together/DeepInfra. Mining and inference are separate tiers — pick one per GPU.

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.

inference revenue, with mining as the floor

Run the Pearl vLLM miner. Your card serves paid inference when there is demand, and falls back to PRL mining when there is not — the gateway switches for you. In private beta — request access.

Your card can also register as a GPU serving node for inference — one card serves whatever model fits its VRAM, and a multi-GPU rig can serve a bigger model. How serving nodes work →
