We published a list of five miners. We had tested none of them. On 10 August 2026 we tested four, and three of them do not support the algorithm at all — including the one in our own copy-paste command. This page is the correction, with the evidence.
--algorithm pearlhash before it opens a socket. That was our error, not yours.Supports Pearl natively. The flag is --coin pearl, not --algorithm pearlhash;
the pool goes in --url and the address in --user. Verified from the binary’s own
--help, which documents “Coin / algorithm to mine, e.g. pearl or btx”.
Not yet run against our stratum with a GPU attached — the machine we tested on has none, and
PeakMiner exits before connecting when it finds no CUDA device. So: the miner speaks pearlhash;
our endpoint has not yet been confirmed end-to-end with it.
Verified two independent ways on the latest release: its own list-algorithms returns
zero matches for “pearl”, and strings on the binary returns zero. The algorithm is
not in the build.
Latest Linux release downloaded and unpacked; strings on the binary returns zero
occurrences of “pearl”.
A genuine PRL miner for AMD (ROCm) and NVIDIA (CUDA). It accepts
stratum+ssl:// only — TLS is mandatory, so until 10 Aug 2026 every AMD owner was
locked out of this pool. Fixed: stratum+ssl://stratum.linkrra.com:5568 is live.
Worth saying how nearly we shipped it broken. The port opened, the service
ran, the firewall was right — and the certificate covered only pool.linkrra.com, so any
client doing normal hostname verification (which is the entire point of a TLS-only miner) would have
failed the handshake. Every check we had passed, because none of them verified the hostname from
outside the box. The certificate now covers both names, and
check-stratum-endpoint.py verifies DNS, public-CA trust, hostname match, subscribe,
authorize and a pushed job before any endpoint gets published again.
Still honest about the remaining gap: we have confirmed the endpoint is usable by a standards-compliant client. We have not yet run krig-miner itself against it with an AMD card attached — we do not have one.
We could not locate any released software under either name that supports pearlhash. Both were listed on this site without evidence. They have been removed. If one exists and we missed it, tell us and we will test it and publish the result either way.

A pool asks you to point hardware you pay for at infrastructure you cannot see. The only thing that makes that reasonable is a habit of saying what has actually been measured and what has not. We would rather lose the miner who wanted five compatible clients than keep the one who finds out the hard way. Every claim above is re-runnable; ask and we will send you the commands.
