Tails OS

Tails (The Amnesic Incognito Live System) is a portable, Debian-based operating system that runs as a live image from a USB stick rather than installing onto the host computer's disk. It is built and maintained by the Tor Project, a nonprofit, and is distributed as free and open-source software. Its design goal is to let someone use an untrusted computer for sensitive work and walk away leaving no forensic trace behind.

Amnesic by design

Tails runs entirely from RAM and never writes to the internal hard disk unless explicitly told to. Each boot starts from the same clean state, and everything done during a session is discarded at shutdown. Users who need continuity can opt into an encrypted Persistent Storage volume on the USB stick to keep selected files, configuration, and keys across sessions.

Tor by default

All network connections are forced through the Tor network, which relays traffic across three independent nodes so that no single observer sees both origin and destination. Applications that try to connect outside Tor are blocked, reducing the risk of an accidental clearnet leak. This makes Tails a common tool for journalists, researchers, and Bitcoiners who want to separate an activity from their identity and location.

For self-custody workflows, an amnesic environment can pair with offline signing practices such as air-gapped signing, and it complements the broader operational-security toolkit covered alongside Tor. Tails is one of several privacy-focused systems sovereign users evaluate when choosing how to compartmentalize risk.
