What is Pearl (PRL)? The proof-of-useful-work coin, explained

Pearl (PRL) is a Bitcoin-style layer 1 mined with AI matrix math instead of hashing. How it works, supply, where it trades and how to hold it.

·6 min read

Pearl (PRL) is a layer 1 coin that works much like Bitcoin, with one big difference: miners secure the network by doing useful AI math instead of burning energy on hashes. If you have been asking “what is Pearl crypto” after seeing PRL on an exchange or a mining forum, this guide covers how it works, its supply, where it trades and how to hold it safely.

How Pearl proof of useful work works

Bitcoin miners compete by running SHA-256 over and over. The result proves effort, but the computation itself has no other use. Pearl replaces that with matrix multiplication, the core operation behind training and running AI models.

  • Miners run noisy matrix multiplications (the project calls the scheme NoisyGEMM, or cuPOW) on Nvidia GPUs.
  • The work is committed and proven with a zero-knowledge proof, so other nodes can check it cheaply without redoing it.
  • Everything else is familiar Bitcoin design: a UTXO model, Taproot addresses and a block reward that shrinks over time.

The idea is that the same hardware and math that power AI can also secure a public ledger, so the energy spent on mining is closer to the kind of work people already pay GPUs to do.

Who is behind Pearl: Pearl Research Labs

Pearl is built by Pearl Research Labs, which publishes the node software, the official Pearl Wallet and the block explorer. The official sources are pearlresearch.ai, the GitHub releases page and explorer.pearlresearch.ai. Community explorers exist too.

The launch is described as fair: no premine, no founder allocation and no VC allocation. Every coin in circulation came from mining.

Mining the Pearl coin

Pearl mining needs Nvidia GPUs. CPU, RAM and storage needs are low. The official Pearl Research pool targets datacenter cards such as the H100 and H200 and charges a 20% fee. Community pools, such as HeroMiners and Kryptex Pool, support consumer Nvidia GPUs.

Newly mined coins need 100 confirmations before they can be spent. To get started, read how to mine Pearl, and see Oyster’s mining docs for payout tracking.

Where PRL trades

PRL trades against USDT on SafeTrade (the largest volume), BigONE and CoinEx. It is not on Coinbase or Binance. Step-by-step guides: how to buy PRL and how to sell PRL for USDT.

Other tokens share the PRL ticker. Perle is a Solana token listed on Coinbase and other large exchanges, and several Pearl Research tokens on Base are not native Pearl. Price sites sometimes show the wrong one first. See Pearl vs Perle.

There is also wrapped PRL (wPRL) on Ethereum. It is a different asset from native PRL, and sending wPRL to a prl1 address does not work.

How to hold Pearl (PRL)

Native PRL lives on the Pearl chain, so you need a wallet that speaks Pearl. Two common choices:

  • Pearl Wallet, the official open-source desktop app for Windows, macOS and Linux, from the Pearl GitHub releases page.
  • Oyster, an independent self-custody wallet that runs as a Chrome extension and as a web app you can add to your phone’s home screen.

Both use the same seed phrase format and address derivation, so a seed from one restores in the other. For a wider comparison, see the best Pearl wallets. Whichever you use, write your seed phrase down on paper and never share it.

Frequently asked questions

What is Pearl crypto?

Pearl (PRL) is a Bitcoin-style layer 1 blockchain built by Pearl Research Labs. Instead of hashing, miners secure it by doing the matrix multiplications used in AI training and inference on Nvidia GPUs, which is why it is called proof of useful work.

What is the max supply of Pearl (PRL)?

2.1 billion PRL, which is 100 times Bitcoin's 21 million. The block reward declines over time. Around 329 million PRL were in circulation in late September 2026.

Was Pearl premined?

Pearl is described as a fair launch: no premine, no founder allocation and no venture capital allocation. Every PRL in circulation was mined.

Where can I trade Pearl (PRL)?

PRL trades against USDT on SafeTrade (the largest market), BigONE and CoinEx. It is not listed on Coinbase or Binance. You can also buy and sell it from the Trade screen in the Oyster wallet.

Is Pearl the same as Perle?

No. Perle is an unrelated Solana token that also uses the PRL ticker. Native Pearl has its own chain, and its mainnet addresses start with prl1.
