Node servers for supported cryptocurrencies are missing
Context
Node servers connect wallets with blockchains and are required for users of cryptocurrency in general.
Problem
Documented (in workbook, website, Discord, and elsewhere) node servers do not exist.
Solution
Search for trustworthy, stable, and well maintained node servers and create a list.
The list should contain at least one localhost (127.0.0.0/16) or private (RFC 1918) accessible network to serve all the cryptocurrencies in use.
Note
Before deciding on servers to list, consider creating the network. It's possibly the only way to ensure high reliability, control, trustworthiness, stability, and maintenance.
