SVIFT

SVIFT is a TUI peer-to-peer file transfer application based on the BitTorrent protocol, built as a foray into networking and distributed computing.

Building

Clone the Git repository

git clone https://github.com/shivrm/svift
cd svift

Run with cargo

cargo run --release --bin=tracker
cargo run --release --bin=server

Architecture

SVIFT uses an asynchronous event-based architecture built on top of Tokio. Each component is an independent actor that communicates with other components through message passing. This allows for lock-free management of many moving parts.

Client Architecture:

Feature Roadmap

• TUI with live status for easier usage
• .torrent metadata creation within TUI
• Automatic peer pruning based on activity and reliability
• Trackerless peer discovery through local multicast and mutual peer exchange
• Peer discovery through DHTs (a good exercise, but is our network big enough?)
• Encrypted communication between peers
• Detailed event log for each torrent instead of a single message stream
• Make TUI nicer to use
