Pavel Durov has just announced the community round for Telegram ICO

I've just bought tokens by 1.3$ and seems like the price is getting higher
www.tongram.ioIs it just me or the more I read the whitepaper, they are really not currently the technology that Telegram uses?
They are a blockchain in development that applications like Telegram, FB messenger etc, could run in - to make it more decentralized and unblockable? Please tell me Im mistaken, or otherwise they are just using the name of Telegram to get some attention?
