Telegram’s involvement with TON and Gram is over. "No present or past member of our team is involved with any of these projects. While networks based on the technology we built for TON may appear, we won’t have any affiliation with them and are unlikely to ever support them in any way." © Telegram

The Free TON Blockchain, or simply Free TON, is a new and independent project based on Telegram's open source code. Free TON blockchain was launched by the Free TON Community and has no association with Telegram.

The main token of the Free TON Blockchain is the Ton, or more formally, the TON Crystal. Test tokens of the Free TON Blockchain are called Rubies.
