headers

need an API that returns N headers. it will replace all of the following
- blockchain.block.headers
- blockchain.block.get_chunk (unused)
- blockchain.block.get_header (unused)
API: getHeaders(startHeight, numHeaders)
make sure that 0 < numHeaders <= 40960, though this upper limit may not be the right one anymore. why do we have it? just because we need some limit?

when Go hub starts, connect to python block processor and load all current headers. keep them in ram
subscribe to block processor's zmq notifications for new headers. full header will be in there.
~~blockchain.headers.subscribe~~ (don't do this until Go hub can read from block processor db directly - aka till we switch to rocksdb)

db

python block processor will emit stream of PUT/DELETE zmq events
go hub will listen to zmq events and write them to it's own pebble db
no more db in python... but python needs db access for processing blocks

federation

speced in #6

server.add_peer
server.peers.subscribe

other

server.ping
server.version
server.features
blockchain.block.get_server_height
blockchain.transaction.broadcast

don't do any of the ones below

needs reorg support

tx can change blocks during a reorg, so we need to handle that correctly to do all this

otoh, doing this reorg support is way easier than doing resolve reorgs. and in fact, btcd may already have all this implemented

blockchain.transaction.get_merkle
blockchain.transaction.get (depends on get_merkle)
blockchain.transaction.get_batch (depends on get_merkle)
blockchain.transaction.info (depends on get_merkle)
blockchain.transaction.get_height
blockchain.address.get_history
blockchain.address.subscribe
blockchain.address.unsubscribe

resolve

wait on this till roy/brannon finish porting chain to Go. they'll be implementing this

blockchain.claimtrie.resolve

unused

blockchain.address.get_mempool
blockchain.estimatefee
blockchain.relayfee
blockchain.scripthash.get_balance
blockchain.scripthash.get_history
blockchain.scripthash.get_mempool
blockchain.scripthash.listunspent

server.banner
