How does the Bitcoin address index work in LibBitcoin?
I see the "fetch-history" aka "fetch_history3" call from Bitcoin Explorer and Client to the Server, which leads to this logic in libbitcoin-server's src/interface/blockchain.cpp:
node.chain().fetch_history(address_hash, limit, from_height,
std::bind(&blockchain::history_fetched,
_1, _2, request, handler));
