How It Works

How a pearl is made

OYSTER builds on Pearl, a Proof-of-Useful-Work blockchain. The work that secures the chain is matrix multiplication performed by real AI inference. Below is what happens to a unit of compute, taken from the open-source Pearl stack, and where OYSTER comes in.

The assay procedure

Assay procedure: how a pearl is made
Step	Stage	What happens	Where in Pearl
1	Grain	A GPU is pointed at the Pearl Network. pearl-gateway pulls a block template from a pearld node and hands the miner a job.	`pearl-gateway · getMiningInfo`
2	Compute	The vLLM miner serves a real model. Its quantized linear layers run on NoisyGEMM kernels, so the model's matrix multiplications are the mining work.	`vllm-miner · pearl-gemm (CUDA)`
3	Proof	When a computation meets the network target, the miner opens a proof. The gateway wraps it in a zero-knowledge certificate, builds the block and submits it to pearld.	`submitPlainProof → submitblock · zk-pow`
4	Pearl	An accepted block pays the coinbase reward in PRL to the miner's Taproot address. The reward can be spent after 100 confirmations.	`prl1p… · coinbase maturity 100`

Then, on Robinhood Chain

MemorandumRE: the OYSTER layer · STATUS: in development

Robinhood Chain is a permissionless, EVM-compatible Arbitrum L2 with gas paid in ETH. OYSTER will keep its participation and accounting there, in smart contracts: linking a person's wallet address to the compute they contribute, so a share of the Reef's work can be tracked in public.

The contracts for this layer are not deployed. Until they are, account figures on the Reef are marked N/A.

Who talks to whom

The miner never talks to the chain directly. pearl-gateway sits between the GPU process and the pearld full node, and OYSTER only reads from the node and the wallet.

What this is not

Is OYSTER a mining pool?: Not today. Pearl mining is solo: each miner's node pays block rewards to its own Taproot address. Pooling or sharing rewards needs an accounting layer that OYSTER has not deployed yet.
Are rewards paid on Robinhood Chain?: No. PRL is the native asset of the Pearl chain and is paid there. Robinhood Chain is where OYSTER plans to account for participation. This site claims no bridge and no PRL token on Robinhood Chain.
What hardware does mining need?: The official vLLM miner uses CUDA kernels, and Pearl's GPU tests currently target sm90 cards (H100, H200). Check the Pearl repository for current requirements before buying anything.
Is the data on the Reef real?: Yes, or it is absent. Nothing is simulated. A window's strip says LIVE when its figures are read from a real source, and a figure with no source connected shows a dash and N/A.

What happens

Where in Pearl

Grain

A GPU is pointed at the Pearl Network. pearl-gateway pulls a block template from a pearld node and hands the miner a job.

pearl-gateway · getMiningInfo

Compute

The vLLM miner serves a real model. Its quantized linear layers run on NoisyGEMM kernels, so the model's matrix multiplications are the mining work.

vllm-miner · pearl-gemm (CUDA)

Proof

When a computation meets the network target, the miner opens a proof. The gateway wraps it in a zero-knowledge certificate, builds the block and submits it to pearld.

submitPlainProof → submitblock · zk-pow

Pearl

An accepted block pays the coinbase reward in PRL to the miner's Taproot address. The reward can be spent after 100 confirmations.
