Chihaya
Chihaya is an open source BitTorrent tracker written in Go.
Differentiating features include:
- Protocol-agnostic and middleware-composed logic
- Low resource consumption and fast, asynchronous request processing
- Unified IPv4 and IPv6 swarms
- YAML configuration
- Optional metrics via Prometheus
Production Use
Facebook uses BitTorrent to deploy new versions of their software. In order to optimize the flow of traffic within their datacenters, Chihaya is configured to prefer peers within the same subnet. Because Facebook organizes their network such that server racks are allocated IP addresses in the same subnet, the vast majority of deployment traffic never impacts the congested areas of their network.
CoreOS
Quay is a container registry that offers the ability to download containers via BitTorrent in order to speed up large or geographically distant deployments. Announce URLs from Quay's torrent files contain a JWT in order to allow Chihaya to verify that an infohash was approved by the registry. By verifying the infohash, Quay can be sure that only their content is being shared by their tracker.
