Pearl Research Labs’ co-founder and CEO is [Omri Weinstein](https://iq.wiki/wiki/omri-weinstein).[\\[5\\]](#cite-id-87JH1KwYVlKubFZc) This protocol replaces traditional hash-based [mining](https://iq.wiki/wiki/mining) with large-scale matrix multiplication, a core arithmetic operation used in artificial intelligence (AI) training and inference. The protocol’s proof verifies matrix computation, but does not by itself establish that the computation serves an AI task or customer-requested inference workload.[\\[9\\]](#cite-id-7vvylpyi0e) Pearl's native [cryptocurrency](https://iq.wiki/wiki/cryptocurrency) is the PRL token (symbol: PRL).[\\[1\\]](#cite-id-RVtItVm08y7Z0vIz)​\n\n## Overview\n\nPearl is a live Layer-1 [blockchain](https://iq.wiki/wiki/blockchain) whose consensus design uses matrix-multiplication proofs in place of conventional hash-based [mining](https://iq.wiki/wiki/mining). The proof establishes matrix computation and associated proof conditions; it does not guarantee that miners perform useful customer AI inference.[\\[9\\]](#cite-id-7vvylpyi0e) Around October 14, 2026, the public [mainnet](https://iq.wiki/wiki/mainnet) explorer showed recent [blocks](https://iq.wiki/wiki/block) and transactions.[\\[10\\]](#cite-id-5oy75ba38d)​\n\nThe Pearl [whitepaper](https://iq.wiki/wiki/white-paper) was published in April 2025, which is rooted in peer-reviewed research on matrix multiplication proofs. By April 27, 2026, the Pearl [mainnet](https://iq.wiki/wiki/mainnet) became operational.[\\[3\\]](#cite-id-6pUXWiOvn4yj6iza) Hashrate Index reports Pearl’s stated launch model as having no pre-mine, no founder token allocation, and no venture-capital funding.[\\[4\\]](#cite-id-n0Sb7Kd7mpT1TwiT)​\n\nPearl's code is available on GitHub.[\\[12\\]](#cite-id-rszsbnl2p9)​\n\nOn August 11, 2026, Pearl released v1.4.1 for a salted noise-seed [hard fork](https://iq.wiki/wiki/hard-fork). The v1.5.0 release followed on October 13, 2026, consolidating security hardening across network and RPC resilience, proof and SPV validation, wallet safety, and service defaults; operators were advised to upgrade. Also on October 13, 2026, Pearl Desktop Wallet v3.0.0 bundled the [node](https://iq.wiki/wiki/node) fixes and changed payment retry handling so a potentially broadcast payment is retained and can be rebroadcast, reducing the risk of duplicate payment.[\\[11\\]](#cite-id-cx4vre6xit)​\n\n## Technology\n\nPearl employs the Proof-of-Useful-Work (PoUW) consensus mechanism, utilizing matrix multiplication (MatMul) instead of SHA-256 hashing like [Bitcoin](https://iq.wiki/wiki/bitcoin).[\\[6\\]](#cite-id-bGtiX8Ip5FPcpTCr) This method secures the [blockchain](https://iq.wiki/wiki/blockchain) through matrix-multiplication proofs. The protocol’s cuPOW/NoisyGEMM proof verifies matrix computation and associated proof conditions, but does not cryptographically establish that the matrices came from an AI model or customer-requested inference workload.[\\[9\\]](#cite-id-7vvylpyi0e)​\n\nBLAKE3 hashes of the input matrices, [mining](https://iq.wiki/wiki/mining) parameters, and [blockchain](https://iq.wiki/wiki/blockchain) state form commitments and seeds that bind [mining](https://iq.wiki/wiki/mining) work to those inputs. The matrix data is organized as a [Merkle tree](https://iq.wiki/wiki/merkle-tree), allowing a verifier to check the relevant matrix portions using Merkle proofs and verify the winning computation. A zero-knowledge proof lets the verifier validate the claimed multiplication and mining condition without seeing the full matrices.[\\[14\\]](#cite-id-59zmdq0hjv) Currently, the implementation focuses on exact integer MatMul, with future upgrades potentially supporting low-precision floating-point formats (BF16, FP8, FP4) though no specific timeline for this transition has been disclosed.[\\[3\\]](#cite-id-6pUXWiOvn4yj6iza)​\n\n​[Blocks](https://iq.wiki/wiki/block) on the Pearl network are targeted every 194 seconds, resulting in approximately 445 [blocks](https://iq.wiki/wiki/block) mined daily, under normal conditions. [Mining](https://iq.wiki/wiki/mining) uses matrix multiplication. A June 2026 preprint by Abhinaba Basu, identified by its author as under review, reported that the dominant mining software examined lacked identifiable inference code, that the protocol accepted proofs based on random matrices, and that the author obtained pool-accepted shares in tests spanning NVIDIA RTX 3090 and AMD MI300X GPUs, as well as CPU and Apple M2 hardware.[\\[9\\]](#cite-id-7vvylpyi0e)​[\\[12\\]](#cite-id-rszsbnl2p9)​\n\n## Products\n\nPearl Research Labs’ website presents inference services separately from the Pearl chain’s consensus mechanism. Its offerings include an OpenAI-compatible serverless inference API, managed inference, and on-premise inference deployments, alongside a multi-model catalog.[\\[1\\]](#cite-id-RVtItVm08y7Z0vIz)​\n\n## PRL Token\n\nPRL is the Pearl network’s native [cryptocurrency](https://iq.wiki/wiki/cryptocurrency), used for [block](https://iq.wiki/wiki/block) subsidies and transaction fees. Miners receive newly issued PRL and transaction fees for valid [blocks](https://iq.wiki/wiki/block).[\\[14\\]](#cite-id-59zmdq0hjv) The [whitepaper](https://iq.wiki/wiki/white-paper) describes ongoing emissions through [block rewards](https://iq.wiki/wiki/block-reward) on a declining curve, while Hashrate Index reports Pearl’s stated launch model as having no pre-mine and no founder token allocation.[\\[14\\]](#cite-id-59zmdq0hjv)​[\\[4\\]](#cite-id-n0Sb7Kd7mpT1TwiT) PRL has a fixed maximum supply of 2.1 billion tokens. The emission follows a polynomial curve, defined as A(t) = t / (t + H), where H equals 650,226 [blocks](https://iq.wiki/wiki/block) (\\~four years), ensuring gradual token release without sudden cliffs like [Bitcoin](https://iq.wiki/wiki/bitcoin)’s [halvings](https://iq.wiki/wiki/halving).[\\[7\\]](#cite-id-SCcIoqnYr3Na3Zg8)​\n\nAs of June 2026, the [block rewards](https://iq.wiki/wiki/block-reward) were approximately 2,700 PRL per block, which results in about 1.2 million PRL tokens being issued daily prior to incorporating transaction fees.[\\[6\\]](#cite-id-bGtiX8Ip5FPcpTCr)​\n\n## Together AI Partnership\n\nIn May 2026, Pearl Research Labs entered an exclusive partnership with Together AI, an open-source AI inference provider valued at over $8 billion following its Series C funding. Together AI described \"Gemma-4-31B-it-Pearl\" as the first product integrating the Pearl Network: an inference endpoint available on Together AI's platform at a discounted rate, over 25% cheaper than standard offerings. The price reduction is offset by expected PRL emissions generated during inference computation.[\\[8\\]](#cite-id-8tCaJynslZVFKEgP)​[\\[5\\]](#cite-id-87JH1KwYVlKubFZc)​\n\n​[Omri Weinstein](https://iq.wiki/wiki/omri-weinstein) noted that this integration marks a shift in AI economics by enabling GPU cycles used in AI tasks to also generate a native digital asset, PRL, without additional cost. Together AI said it planned to expand its portfolio of Pearl-powered products and potentially offer customers ways to obtain a portion of currency emissions.[\\[7\\]](#cite-id-SCcIoqnYr3Na3Zg8)​[\\[5\\]](#cite-id-87JH1KwYVlKubFZc)​\n","recentActivity":"{\"items\":[{\"id\":\"3e05e96a-fc39-4d28-9482-7f3d81ac7cee\",\"title\":\"Pearl \",\"description\":\"Pearl is a Layer-1 blockchain protocol developed by Pearl Research Labs utilizing Proof-of-Useful-Work with its native token PRL.
