Our error messages are not consistent regarding the use of quotes, e.g. some quote the function name and contract name, others don't.
We should agree on how we want to do that and make it consistent everywhere.

Background
When a node has multiple private channels with the same peer, the hop hints in their payment requests will be populated with multiple channels. The purpose of these hop hints is to specify the next node's key and indicate the fees and cltv delta needed for route construction.
In pathfinding, due to non-strict forwarding, an LND node paying to this destination will only use the

The blockchain v2 reactor utilizes concurrency to saturate the bottleneck of writing blocks to disk. This concurrency is internal to the reactor where the reactor itself will launch and manage internal state machines running as go-routines. This configuration makes testing difficult as we don't know when messages processed by internal state machines will be processed and when we can assert that th
