OYSTER
$OYSTER / $PEARL
The world is your oyster.
The little oyster of the Pearl network. Pearl mines with the math that runs AI. Oyster explains it with a little less jargon.
Tap the oyster to poke it.
Every pearl starts as grit.
Bitcoin miners spend enormous amounts of power guessing numbers. The guesses secure the chain, and then they're thrown away. Pearl asked what would happen if the work securing a chain was work people actually needed.
Pearl is a layer-1 blockchain built on Proof of Useful Work. Its unit of mining work is FP8 matrix multiplication on GPUs, the same math every AI model runs on. Every tile of that math doubles as a lottery ticket for the next block, so a GPU answering a prompt can mine Pearl at the same time.

Pearl's own wallet software is called Oyster (more on that below), so we took it personally. Oyster is the network's mascot. It explains Pearl with a little less jargon and stays unbothered while doing it.
Pearl's wallet is called Oyster.
Pearl's official software ships with a wallet named Oyster. It sits next to the node and the command-line tools in Pearl's own repository. We weren't going to let that slide.

How a pearl gets mined.
Pearl's whitepaper describes what an honest miner does with AI work it wanted done anyway. Here are the six steps, with less math.
Line up the job
A GPU already has AI work queued: two big matrices to multiply. It packs them into a compact format called FP10.
Commit first
Before any math runs, the miner fingerprints both matrices with a hash tied to a recent block. No take-backs, and no reusing old work.
Add a little noise
Those fingerprints generate random noise the miner can't choose. A thin, low-rank layer of it is mixed in, then everything is rounded to FP8.
Multiply
The GPU runs the same matrix multiplication it would have run anyway. This is the expensive part, and it's also the useful part.
Scratch the tickets
The answer is cut into tiles, and each tile is hashed into a lottery ticket. A ticket under the network's target wins the next block. Losing tiles are thrown away.
Clean up, keep the answer
Because the noise is low-rank, the miner subtracts it back out cheaply and keeps its AI result at normal FP8 accuracy.
- Unit of work
- FP8 matmul
- Noise rank
- r = 32
- Ticket size
- 256 bits
- Hash
- BLAKE3
- Mining overhead
- 1 + o(1)
How the network checks a win
One tile, not the whole job
Verifiers recompute just the winning tile. Approved GPUs do arithmetic the same way every time, so the result has to match bit for bit.
No shortcuts
A "jackpot policy" rejects tiles built from suspiciously easy matrices, like low-rank or mostly empty ones. You can't win faster by skipping the real work.
Works for modern models
The protocol extends to mixture-of-experts models, and a zero-knowledge verifier can confirm a win without exposing the data behind it.

Three moods. That's the whole range.
Tap each one. Oyster reacts, then goes right back to how it was.

Contract address drops at launch
Always check the contract address here before you buy. Anyone can make a token called OYSTER.
Come out of your shell.
Four steps from zero to holding $OYSTER.
Get a wallet
Download a wallet app that supports the chain and write your recovery phrase down somewhere offline.
Add funds
Buy the chain's native coin on an exchange and send it to your wallet address.
Swap
Open a DEX, paste the contract address from this page, and swap for $OYSTER.
Close the shell
That's it. Stay unbothered while the GPUs do something useful.
A little less jargon.
Oyster puts on its glasses and explains Pearl in plain words. Four terms get you most of the way there.
- Proof of Work
- Miners race to solve a puzzle whose only purpose is proving they spent power. Once a block is found, that work is thrown away.
- Proof of Useful Work
- Miners multiply matrices they needed for AI anyway. Every tile of the result doubles as a lottery ticket for the next block.
- Inference
- A trained AI model turning your input into an output. On Pearl, answering a prompt and mining a block can be the same job.
- PRL
- Pearl's native coin, mined by GPUs while they run AI. Mining rewards already fund a discounted Pearl-powered model on Together AI.
Same idea, different shell.
An oyster turns an irritation into something valuable. Pearl does the same with computing power.
