chainparams: delete my DNS seed #35691

   sipa commented at 12:37 PM on July 9, 2026: member

   I plan to shut down my DNS seed server in the future (probably after the release of 32.0), so I request it be removed from the master branch already. It has existed for almost 15 years at this point, and isn't getting much maintenance attention from me anymore.

   Are you also planning to stop maintaining https://github.com/sipa/bitcoin-seeder? (it wasn't the most active repo, but still)

   Also remove the instruction from contrib/seeds/ that pulls from your seeder?

   @Sjors I'll address critical bugs if there are any, but I haven't really maintained it beyond that for a while. @achow101 Done.

    If we end up wanting a replacement seed, I think @willcl-ark has some seed infra that has been running for a while now.
