What is being described

Pearl Research Labs describes itself as building infrastructure and algorithms for AI inference S-3603. It develops the Pearl blockchain, an instance of proofs of useful work:

  • Protocol specification. Pearl specifies a proof-of-useful-work protocol in which the unit of mining work is FP8 matrix multiplication on GPUs S-1105.
  • Integer whitepaper. Its earlier whitepaper presents mining as a side-effect of the matrix multiplications in AI training and inference workloads S-1106.
  • Open-source network. Pearl publishes a monorepo with a reference full node, a vLLM-based GPU miner and a proof-of-work circuit and verifier S-1107. Its README says the mining follows the proof of useful work from arbitrary matrix multiplication proposed by Komargodski and Weinstein S-1107 S-1609.
  • Reproducible GPU arithmetic. Pearl and Stanford researchers published Hawkeye at MLSys 2026 S-1010. It re-executes on a CPU, bit for bit, the matrix multiplications that NVIDIA Ampere, Hopper and Ada Lovelace GPUs perform in FP16, BF16 and FP8 S-1010; see Deterministic and bit-exact inference.
