Better documentation for remote bitcoind - #3359
Merged
Merged
Conversation
Our documentation didn't make it clear enough that `bitcoind` should ideally run on the same machine as `eclair`. If that's not possible, since `bitcoind` doesn't provide support for TLS for its RPC and ZMQ endpoints, the node operator MUST setup a secure tunnel (providing encryption and authentication) between `eclair` and `bitcoind`. If that isn't provided, a network attacker may drop or alter messages between `eclair` and `bitcoind`, which can lead to a loss of funds.
