soxy-chains is a scalable multi-layer TCP traffic tunneling application, providing thus military-grade traffic encryption capabilities. It supports an arbitrary number of layers that spans an arbitrary number of hosts.

1. A pool of 30 IP addresses for web crawling at max.
2. Avoid using Tor on the external layer as the addresses are more likely to be black-listed.
3. Only public VPN can be used, some of which may keep logs.

An satisfying solution consists of two layers of tunneling : VPN over Tor.

• We'll use a layer of tor nodes as entry points to keep us anonymous vis-à-vis the public VPN providers.
• We'll use an external layer of VPN nodes as a target-facing clients.

soxy-chains is docker-powered and can scale to an arbitrary number of hosts. You can use it on your local computer, over multiple virtual machines or via a cloud provider for larger setups.
