Bitcoin Core Considers Dropping CJDNS Support Due to Eclipse Attack Risks

Bitcoin Core developers are considering dropping support for encrypted routing as part of their network transport. The current system, known as CJDNS, is seen as a liability due to its low usage and potential vulnerability to eclipse attacks.

A recent discussion on the Bitcoin Core issue tracker revealed that only seven out of 22 reachable nodes were deemed 'good' by the seeder database, while users have reported seeing only three or four peers despite having 11 fixed CJDNS seeds.

Some contributors suggested deprecation and warned users in a future release before planning removal in version 33.x. However, no implementation branch or pull request has been created yet.
