To further improve the reachability of the Cardano mainnet, one of SPIDR’s relays is now also available on Tor’s onion network. You can use:
dewzb2r7babrkd2ayiqara5drp23zrshdbpn2fe5spxewtlh3yv2bsqd.onion:3001
To connect to it. For most users this will not be too interesting. Using Tor to connect to a regular relay over the internet should be secure enough for most users.
Mind you, currently cardano-node software does not support connecting over SOCKS5, so you would have to do make some changes to the source code for now.
