Telegram investor update claims TON is now 90% complete

Telegram, one of the most prominent and secretive projects in the cryptocurrency space, has released its latest investor update on the state of its Telegram Open Network (TON) development, embedded below. 

According to the investor update, the overall build of the TON network is now 90% complete, an increase from 70% in September 2018. To be sure, measuring technical development progress by percentages is an arbitrary process.

The investor update also shows that Telegram has delayed its testnet launch to March 2019. The original launch date was expected to be January 2019.
