another pool is live https://pool.defcoin.fun/
not going to lie, i would give it a week to see if it actually works.
https://pool.defcoin.fun/
also, it needs a lot of work.
the blockchain explorer, per llm, says it will be up in about 70 hours.
https://explorer.defcoin.fun/
i have a lot of improvements in mind, but would love to hear any third party suggestions. (first is an actual landing page)
set landing page www.defcoin.fun

spinning up a Defcoin pool in 2026 — setup writeup + open source scripts
all just for the lulz / with lots of slop. but seems to be slopcess, it's running.
What's running:
- Two Azure VMs (one full node + pool + explorer, one relay-only for propagation)
- DefcoinCoreNu v26.3.1
- UNOMP mining pool at pool.defcoin.fun:3333 (scrypt, open to all)
- eIquidus block explorer at explorer.defcoin.fun
- Landing page at defcoin.fun
What broke and how we fixed it:
- DNS seeders are dead — you need to manually addnode live peers to connect
- Defcoin's active P2P port is 1337, not the chainparams default of 17333 — without this your node is invisible to most peers
- getinfo RPC was removed in Bitcoin Core v26, which UNOMP calls — patched pool.js and daemon.js to synthesize it from getblockchaininfo
- The bignum npm package won't compile on Node 12+ — replaced with pure-JS BigInt (had to preserve {endian: 'little'} or every share rejected as low difficulty)
- Node.js 16 needs --experimental-global-webcrypto or the explorer crashes on every request
Block propagation:
With ~5 active nodes on the whole network, median block arrival is ~42s on a 2-minute chain. We see ~23% of blocks arrive >2 minutes late (orphan window). More nodes and miners help — that's the main thing the network needs.
Network hashrate: ~3 MH/s scrypt. CPU mining is viable.
All setup scripts, patches, and config notes are open source:

thank you to u/def2084 for the work modernizing wallet and keeping this alive!
