Platho — private messaging and free speech that nobody can switch off. Private correspondence is a right, not a privilege. So is speaking freely. Platho is a messenger that runs straight from your device over the open TON network: no servers, no operator, no central gateway that can read, throttle or block you. Private messages are end-to-end and post-quantum encrypted. Only you and the person you write to hold the keys. No company, court or government can open them, because there is no central place where they sit. Public posts live on open, verifiable on-chain state. Nobody can quietly rewrite or erase them — not even you. Your identity, your name (.ath usernames are NFTs), your messages and your funds are anchored to your own wallet, not to an account someone else can close, suspend or empty. ATH is the token behind this economy. Fixed supply of 100,000,000 — no minting, no admin keys: the contracts have no pause, blacklist, transfer tax or forced transfer. ATH was distributed to early users for activity in the app and is spent on .ath usernames and profile updates. Your words stay yours. Your keys stay yours. That is the whole point.
