Although Telegram has terminated its blockchain project, Telegram Open Network (TON), in May 2020, the TON test net has been apparently running for almost one year.

In a July 6 update, the official TON development group on Telegram announced that it would be discontinuing its support of the test network for TON. Remaining TON validators will be turned off by August 1. In the post, the TON official recommended network participants save all their relevant data and stop their testing processes.

Despite the testnet being set to shut down less than a month from now, network participants will still be able to continue their experimentation after the testnet is terminated. In order to do that, users can install their own testnet validators, described in greater detail in three different how-to documents containing guidelines for the Full Node, the Validator, and Test Grams.

The testnet was launched in September 2019

Telegram launched the TON testnet for explorer and node software on Sept. 6, 2019. In anticipation of its scheduled Oct. 31 launch last year, the company released an alpha version of an iOS wallet to work with its native token, the Gram. But Telegram’s TON plans were never fully realized, as the United States Securities and Exchange Commission suddenly deemed Telegram’s $1.7 billion ICO illegal in mid-October.

After a long-running legal battle with U.S. regulators, Telegram agreed to shut down its TON project, as well as return $1.2 billion to investors in line with a court-approved final settlement. As officially announced by Telegram CEO Pavel Durov, the firm had already reimbursed more than $1.2 billion by June 25.
