PearlHash Mining Explained
Published: June 2026 · Category: Education
What Is PearlHash?
PearlHash is the mining algorithm used by Pearl / PRL. A miner repeatedly tests possible solutions for the current network job. Most attempts are discarded locally because they are not strong enough. Only results that meet the pool target are submitted as shares.
This is why a GPU can perform a very large number of hash attempts per second while only sending a small number of shares to the pool. The miner is not sending everything. It only sends results that pass the assigned share difficulty.
Hash Attempts vs Pool Shares
A GPU searches locally. Every hash attempt is a lottery ticket. The pool gives the miner a job and a difficulty target. If the miner finds a result that meets the pool target, it sends a share. If the result does not meet the pool target, it is ignored locally.
| Hash attempt | Local GPU calculation. Usually not sent to the pool. |
| Accepted share | Valid work for the pool difficulty. Counts toward pool accounting. |
| Candidate | Gateway-submitted block candidate/proof. Not the same as a confirmed block. |
| Confirmed block | A real network block accepted by the Pearl network. |
Pool Difficulty
Pool difficulty controls how often miners submit shares. If difficulty is too low, high-end GPUs submit too many shares and create unnecessary traffic. If difficulty is too high, small miners submit very few shares and stats update slowly. A mining pool tries to balance this so miners submit a reasonable number of shares.
Pool difficulty is not the same as network difficulty. A share can be valid for the pool without being strong enough to become a confirmed network block.
Candidate Submissions Are Not Confirmed Blocks
PearlPool.cloud may show candidate counters. These are transparent gateway-submission counters. They help miners see that proofs or block candidates are being submitted, but they are not confirmed blocks. Confirmed pool blocks are shown separately on the Blocks page and API.
Candidate Submissions = submitted gateway proofs/candidates, not confirmed pool blocks.How a Real Block Is Found
A real block is found only when a submitted result also meets the much harder network target. This is probability-based. A small pool can find a block quickly or can wait longer than expected. Pool luck, network difficulty and pool hashrate all matter.
For this reason, PearlPool.cloud separates shares, candidate submissions and confirmed blocks. This avoids confusing submitted work with real network block rewards.
