What Pearl Is
Pearl is a Layer 1 blockchain developed by Pearl Research Labs that uses Proof-of-Useful-Work, where mining is produced natively from AI computations. Its mainnet launched in April 2026, and the coin is also listed under the ticker PRL on some exchanges.
The project builds on a 2025 cryptography paper on proofs of useful work from matrix multiplication. It starts from the idea that energy spent on mining should go into computation that is actually useful, rather than hashing alone.
Mining via Matrix Math
At the heart of Pearl is a new, efficient implementation of matrix multiplication, the core GPU operation. This lets GPUs produce proof-of-work as a side effect of AI training and inference workloads, which the project describes as a 2-for-1 design.
Miners perform matrix multiplications on GPUs, commit to the results, and use zero-knowledge proofs so the chain can verify the work cheaply. The project says this intertwines energy, data, and money into a single digital asset.
Supply and Ecosystem
According to available sources, Pearl has a maximum supply of 2.1 billion coins, with new coins issued through GPU mining. Readers should check official documentation for exact emission schedules and distribution details.
In May 2026, Pearl partnered with Together AI to launch an inference endpoint where the computation also participates in Proof-of-Useful-Work. Since mainnet, GPU mining participation has grown quickly and drawn attention from the mining community.
Strengths and Risks
Combining mining with AI workloads aims to address criticism of wasted energy in traditional proof-of-work. Its foundation in published academic research is also seen as a technical strength.
However, the mainnet is young, so its security and long-term economic model are not yet fully proven. The real-world usefulness of the work, mining concentration, and regulation remain open questions, and this overview is not investment advice.
