Pearl FP8 fork: which pools and miners are getting ready
Who is building for PIP-3: the Pearl node's FP8 branch, BzMiner's FP8 jobs, OneZeroMiner and WildRig on Hopper, Kryptex's pledge, and the first FP8 blocks on a test network.
PIP-3, the proposal that moves Pearl mining from INT8 to FP8 math, is still a Draft with no activation height. The code for it started in September and has been quiet since 5 October. We went through the Pearl code, every miner's release notes and the pools' announcements to see who is getting ready. Everything below is as of 31 October 2026, with a link to each source.
New to the fork? Start with Pearl FP8 fork (PIP-3): will your GPU still mine PRL?
The short version
| Who | What | FP8 status |
|---|---|---|
| Pearl Research Labs | Node and reference miner | FP8 code in progress on its own branch |
| BzMiner | GPU miner | FP8 jobs since v100.20 (11 September) |
| OneZeroMiner | GPU miner | Hopper and Blackwell supported; FP8 not announced |
| WildRig Multi | GPU miner | Hopper supported; FP8 not announced |
| SRBMiner-MULTI | GPU miner | FP8 not announced |
| Kryptex | Pool | Says it will support the fork |
| Peryn | Pool | Plans around the fork; FP8 support not announced |
| Other pools | Pools | No public statement yet |
| pearl-apple-miner | Community miner | FP8 blocks mined on a private test network |
No public pool sends FP8 jobs yet, so nobody can mine FP8 on the real network today.
Pearl Research Labs: the FP8 code
The FP8 work lives on the fp8-scheme branch of the Pearl repository. Pull request #311, "certificate-v4 + mining", opened on 9 September, holds the new certificates and the mining code. It is still open.
- 27 September: Hopper support (H100) was merged into the branch, next to Blackwell (B200). These are the two architectures PIP-3 names.
- Early October: fixes for bit-exact results, input checks and the zero-knowledge proofs. The last changes on the branch are from 5 October; nothing new has landed since.
The node releases in October, v1.5.1 to v1.5.5, are fixes for today's network. None of them contains FP8 code.
In the code, the new certificates are called version 4. The PIP text still calls them version 3. Same thing, different label.
PIP-3 itself has not changed: status Draft, deployment "TBD". It says a reference miner will be published before the proposal moves to the next stage, Proposed.
Miner developers
- BzMiner is the only miner that announces FP8. Its v100.20 release on 11 September says: "Pearl mines certificate-v4 FP8 jobs on NVIDIA and AMD". It can only do that where a pool or node sends FP8 jobs, and none does on the real network yet. Note that PIP-3, as written, lists only NVIDIA Hopper and Blackwell, not AMD.
- OneZeroMiner added Blackwell and Hopper cards (RTX 50 series, H100, H200, H800, B200) in v1.7.7 on 1 October, and made them about 4% faster in v1.8.2 (an H100 at 807 TH/s). That is for today's INT8 algorithm, but these are the cards that keep mining after the fork. No FP8 mention through v1.8.4 (27 October).
- WildRig Multi added NVIDIA Hopper in 0.50.4 and 0.50.5 in late August, also for today's algorithm. No FP8 mention through 0.51.8 (24 October).
- SRBMiner-MULTI has no FP8 mention through 3.8.3 (30 October). Its recent releases make RTX 30, 40 and 50 cards and the A100 faster on today's algorithm.
Pools
- Kryptex wrote in its FP8 fork article (updated 7 October) that it "supports every Pearl fork, including future ones". It also quotes the team: there is no date, the network upgrades once the team is confident in the security, and "if doubts remain, there will be no fork".
- Peryn, a new pool, writes on its mining page that Hopper and Blackwell cards keep mining after the upgrade while Ada, Ampere and Turing cards mine until then, and its zero-fee "Founding Miner" offer closes at the FP8 upgrade. It does not say when it will send FP8 jobs.
- PearlHash, Pearl Fortune, Lucky Pool, HeroMiners, Jetski and the rest have not said anything public about FP8 that we could find. A pool usually announces support together with the node release, so this is normal at this stage.
The community
- pearl-apple-miner, a miner for Apple Silicon Macs, already mines today's certificates on the real network. Its FP8 build mined 3 FP8 blocks on a private test network, with results that match the B200 reference bit for bit. Its readme also notes that no public pool runs FP8 yet.
- The same developer opened a discussion (pips#14) on 2 October: should a later fork add an exact INT8 profile next to FP8? That would let more hardware back in. It is a pre-proposal discussion, not a plan.
What this means for you
- Keep mining as you do now. The fork needs an activation height, a node release and pool support first, and none of them exists yet.
- On RTX 50, H100 or H200? Your miners already support these cards today. When the fork comes, update the miner and you keep going.
- On RTX 30 or 40, AMD or Intel? Nothing announced changes the picture. As PIP-3 reads today, these cards stop mining Pearl at the fork.
PearlStation tracks PIP-3 on the fork tracker and new miner releases every hour. With Pro you get a Telegram message the moment a new miner version is out. We will post here when the fork gets a date.
