About this source
sysfix-pools fills a real gap in the mempool.space registry: lesser-known pools (NiceHash, KuCoin, regional Asian pools) and historic pools that mempool's registry has trimmed. Run alongside mempool-pools-v2 it gives broader coverage with no double-counting. 200 supplementary addresses, 16 unique pool names not in the primary registry.
How we got the data
Cloned from sysfix/mining-pool-addresses on GitHub. Per-pool JSON parsed; addresses tagged with pool name and reserved a supplemental source slug so they don't collide with the primary mempool registry.
Why this confidence
Same level as the primary registry. The maintainer audits against on-chain coinbase patterns before adding entries.
License & attribution
Open-data license per upstream. We retain the upstream pool slug in source_ref.
Sample addresses
python tools/build_labels_db.py --update --only sysfix-pools
to populate it.
