CoinVoice has recently learned that TON’s official Twitter account added the Resistance Dog logo hand-painted by Telegram’s founder in 2018 to its avatar.
According to the TON Foundation, the hoodie-wearing dog (also known as the Resistance Dog) was originally hand-drawn and named by Telegram and TON founder Pavel Durov in 2018, and REDO has been the (un)official mascot of Telegram's vision of "resisting" censorship since then. [Original link]
