Pearl mining updates: node v1.5.3, wallet v3.0.0 and faster miners
Everything Pearl miners got from 10 to 21 October 2026, including the node v1.5 security release, desktop wallet v3.0.0, and new SRBMiner, WildRig and BzMiner versions.
Two busy weeks for Pearl. The node went from v1.4 to v1.5.3, the desktop wallet reached v3.0.0, and all three GPU miners shipped faster Pearl kernels. Here is everything in one place, newest first, with links to the release pages.
Pearl node v1.5.0 to v1.5.3
- v1.5.0, 13 October: security hardening. Bounds on request sizes and on what one peer can use, better RPC authentication, and stricter transaction, signature and proof validation. Anyone running a node should be on v1.5 or newer.
- v1.5.1, 15 October: enforces the order of transactions inside a block.
- v1.5.2, 17 October: keeps read-only UTXO lookups out of the cache.
- v1.5.3, 21 October: keeps full grain precision in transaction amounts over RPC.
All releases: Pearl on GitHub.
Desktop wallet v3.0.0
Released on 13 October for Windows, macOS and Linux: Pearl desktop wallet v3.0.0. Download wallets only from the official GitHub releases page.

- 3.7.7, 18 October: Pearl improvements for NVIDIA RTX 3000, 4000 and 5000 series.
- 3.7.8, 19 October: better Pearl efficiency on the same cards, and a fix for RTX 5000 cards on newer drivers (615 and up).
- 3.7.9, 20 October: better efficiency on RTX 5000 series.
WildRig Multi 0.51.4 to 0.51.6
- 0.51.4, 10 October: a new power-efficient Pearl kernel, turned on with
--pearlhash-kernel 2. The developer fee is 0% when mining on PearlHash. - 0.51.5, 16 October: up to 5% faster on RTX 3000 and 4000 series (the release notes advise locking memory clocks at 810 MHz), and a slightly better kernel 2 on RTX 5000.
- 0.51.6, 21 October: up to 4% faster and more efficient on RTX 3000, 4000 and 5000 series, and better on the Tesla V100.
BzMiner v100.46

- Before that, v100.45 on 2 October brought about 2% more speed on NVIDIA and big improvements for Intel Arc Battlemage cards.
Which miner should you use?
It depends on your card and your pool, and the gaps change with almost every release. The best test is your own: run each miner for an hour on the same pool and compare the hashrate the pool reports, not the number the miner prints. PearlStation shows the pool-side hashrate for every worker, across every pool, side by side.
Not every pool documents every miner. The pool guide in the app lists the servers and the miners each pool supports.
