Talking to an ElectrumX server, the way a Doichain wallet or web page does:
a WebSocket carrying JSON-RPC, and a check that the server really follows
the Doichain chain.
A server answers with whatever chain its node follows and sends no proof for
it. verifyChain asks for a block only the valid chain has, so a
server on the old chain is caught before anything it says is believed.
