PolMine

PolMine (polmine.pl)

PolMine (stylized as Polmine) is best known as an early Bitcoin mining pool, described on Bitcoin Wiki as the first Polish mining pool, with the website listed as https://polmine.pl. (en.bitcoin.it)

What it did

A Bitcoin mining pool is a service where multiple miners combine computing power to increase the probability of finding blocks and receiving rewards (which are then shared according to the pool’s payout rules). In historical block-explorer data, blocks have been attributed to “Pool: Polmine.pl”, indicating that the pool successfully mined Bitcoin blocks (at least during the period when it was active).

Identifiers and references

Bitcoin Wiki notes that PolMine used the coinbase signature “by polmine.pl” as an identifier in mined blocks. (en.bitcoin.it)
Independent, older code/data lists also include an entry for “/wallet/Polmine.pl = Polmine.pl”, consistent with it being tracked as a mining-pool entity. (gist.github.com)

Current status of the website

As of February 17, 2026, direct attempts to load polmine.pl did not succeed (fetch/timeout errors), so the site may be offline, moved, or otherwise not publicly accessible at present. ([]())

Potential for name confusion

The name “PolMine” is also used elsewhere (e.g., in academic/digital humanities contexts), but those are separate from polmine.pl, which is primarily documented as a Bitcoin mining pool domain. (text-plus.org)
