Bitcoin Core Considers Dropping Encrypted Routing Support Amidst Node Health Concerns

The Bitcoin Core team is considering dropping support for encrypted routing as poor node health exposes users to eclipse attacks. A discussion on GitHub reveals that only seven of 22 reachable CJDNS addresses are considered good, with some nodes having as few as three or four peers.

Andrew Chow pointed out that one seeder database held 25 CJDNS addresses, but only classified seven as good. Martin Zumsande reported seeing only a handful of peers despite Bitcoin Core shipping with 11 fixed CJDNS seeds.

The low peer count has led to support for deprecation and suggestions to warn users in a future release before removing the feature entirely. However, no implementation branch or pull request has been created yet.
