Toncoin's origin lies with the Telegram Open Network (TON) blockchain, initially developed by brothers Pavel and Nikolai Durov, the founders of Telegram, but later evolved into a decentralized, open-source project.

there's a more detailed breakdown:
Initial Developers:
The original project, Telegram Open Network (now The Open Network), was initiated by Pavel and Nikolai Durov.
Legal Issues & Evolution:
The project faced legal issues related to the native token Gram (later renamed Toncoin) when the U.S. Securities and Exchange Commission (SEC) intervened, claiming it was an unregistered security.
Shift to Open Source:
Telegram was forced to abandon its involvement, and the project became open source.
Community Driven Development:
The project continued under a new name, "The Open Network", with development led by the community and later a foundation, the TON Foundation, which was established by Anatoliy Makosov and Kirill Emelianenko.
Toncoin (TON):
The native cryptocurrency of the TON blockchain is called Toncoin (TON).
