1Hash

1Hash (1hash.com) — miner / block-producing pool

1Hash is best documented as a Bitcoin proof‑of‑work (PoW) mining pool (i.e., an entity coordinating hashpower from miners and publishing valid Bitcoin blocks when it finds them). In Bitcoin terminology it is a miner/pool, not a proof‑of‑stake “validator” in the Ethereum-style sense; its “validation” role is the PoW role of constructing and propagating blocks that the network’s full nodes then verify.

What is publicly known

• Identified as a Chinese mining pool (mid‑2010s): Contemporary coverage during the 2016 scaling / SegWit signaling era described 1Hash as a Chinese mining pool and noted that “not much else is known” publicly about it. (nasdaq.com)
• SegWit-era signaling posture (2016): In late 2016 reporting on miners’ signaling positions, 1Hash was listed among pools not signaling support for Segregated Witness (SegWit) at that time. (nasdaq.com)
• Sometimes grouped with 58coin / 1THash in academic or survey literature: A later secondary source discussing mining pools lists “1Hash & 58coin” as a Chinese pool formed from “1THash and 58coin,” indicating the name appears in the literature amid pool identity/label consolidation. (doras.dcu.ie)
• Referenced in datasets by website and geography: A research dataset/table of mining pools lists “1Hash” (server location: China) and associates it with the website http://www.1hash.com/. (assets-eu.researchsquare.com)

Website availability (as checked)

• As of March 6, 2026, fetching https://www.1hash.com returned a 502 Bad Gateway via the retrieval tool used here, so the site’s own “About/Contact/Operator” details could not be confirmed directly from the homepage at this time. ([]())

Bottom line for “miner-validator” categorization

• Category: Miner (mining pool / block producer) on Bitcoin PoW networks.
• Attribution/ownership: Not clearly attributable from broadly available public sources (at least from the sources surfaced here); multiple contemporaneous summaries explicitly note the lack of public detail. (nasdaq.com)
