On May 12, Telegram officially terminated its involvement in its planned blockchain project, the Telegram Open Network, and its corresponding GRAM token. Apparently ending its long-running legal battle with the United States’ regulators, Telegram still needs to sort out $1.7 billion raised in an initial coin offering, or ICO, in 2018.
Prior to abandoning the troubled TON project, Telegram CEO and founder Pavel Durov introduced a reimbursement scheme, offering TON investors two choices — immediate 72% refund, or a 110% refund in 12 months.
