How aarenrishikdevloper/torrent-client works
This is a C++ BitTorrent command-line client. A user supplies a torrent file and download directory; the CLI constructs TorrentClient, which parses metadata, discovers peers through trackers, manages peer connections and piece downloads, verifies and writes completed pieces, and reports progress. Tracker refresh and worker-thread coordination are also part of the client workflow. The parser’s bencoding and hashing support is shown as an internal layer. Several peer-protocol modules are present in the tree, but their implementation was not sampled, so their detailed wiring is not asserted.
