YGOOW — Blog

Six weeks of measuring our own code on the phone it runs on — timing of every primitive, the size and rhythm of every frame, the strength meter, the backup file.

YGOOW used to let you seal a message so it only opened near a place.

Going post-quantum usually means parking one-time keys on a server.

In 2020 police read tens of thousands of EncroChat users' messages without breaking the encryption — they owned one central system and harvested everyone at once.

In 2024 German investigators deanonymised a Ricochet user without breaking Tor or the cipher — they timed the network and made the ISP name the subscriber.

The cipher is the solved problem.

A message in YGOOW passes through up to five independent layers — transport, Tor, the end-to-end channel, locked content, and a lifetime.

Every other messenger chooses a default and hopes you never ask.

Why a twenty-year-old idea — anonymous, account-free data sharing — is finally shipping as an encrypted messenger.

A wrong key, a missing key, and a message that was never yours all produce the same locked block — no error, no hint, no oracle.
