Telegram ICO technical whitepaper - does it exist? Telegram provides a "marketing whitepaper" here:

The authors do refer to a technical whitepaper but I can't find it on their website. If it sounds like a scam, reads like a scam it is probably a scam?
There is a post on Reddit with TON Whitepaper uploaded to Google Disk.
The source is said to be TON telegram channel.
