Bitcoin Knots release 29.4.2.knots20260508
There is a registry maintained by (whoever runs) https://mempool.guide, at https://start9.mempool.guide - you’d add that as a registry via StartOS web-UI > Marketplace > Start9 Marketplace > +Add
Beware - this is run completely by a third party and Start9 has no control over it. Never add a 3rd party registry unless you trust the maintainer.
