A: No. Libbitcoin is the oldest implementation of Bitcoin that is not a fork of the Satoshi code. The implementation is dramatically different and contains no Satoshi source. A: BS is a Bitcoin full node and query server, built on libbitcoin-node and libbitcoin-protocol. It is conceptually similar to Electrum Server except that its query interface is more generalized and it incorporates its own full node in contrast to Electrum's use of bitcoind. By default BS indexes every payment address and stealth payment in the entire blockchain. BS is a console application implemented as a thin command line and configuration settings wrapper around the libbitcoin-server development library.
