In this commit, we introduce a nice optimization with regards to lnd's interaction with a bitcoind backend. Within lnd, we currently have three different subsystems responsible for watching the chain: chainntnfs, lnwallet, and routing/chainview. Each of these subsystems has an active RPC and ZMQ connection to the underlying bitcoind node. This would incur a toll on the underlying bitcoind node and would cause us to miss ZMQ events, which are crucial to lnd. We remedy this issue by sharing the same connection to a bitcoind node between the different clients within lnd.
routing
The routing package implements authentication+validation of channel announcements, pruning of the channel graph, path finding within the network, sending outgoing payments into the network and synchronizing new peers to our channel graph state.
