I don't think this is a good choice. The library's last release was in 2016, and it also has some disadvantages, especially for someone trying to build an exchange:
### Disadvantages:
Not a full node, has no idea what blocks are
Relies on centralized service (blockchain.info) for blockchain operations, although operations do have backups (eligius, blockr.io)
Yeah, not having a release since 2016 is why i steered clear of this one. It also looks quite low-level. I want something high level so i can have a high level understanding of bitcoin development quickly, and then moving onto a high level understanding of lightning development. Im am not interested in going too low-level.
