- Replaces Hackney with Finch for http requests, to improve concurrent
RPC handling under high load
- Rips out obsolete elixometer instrumentation
- Adds handling for failed prevout inflation
- Fail inflation step fast
Fetch prevouts for solo and block transactions,
and calculate input values & tx fees.
Naive initial implementation with no caching,
so block processing is sloooooooooooooow.
Avoid sending large block data messages over websocket,
which block transaction updates, especially on lower
bandwidth connections.
Instead, only send the block id over websocket, and
then fetch over http with good caching
