TON (The Open Network)
A layer-1 blockchain originally designed by the Telegram team and, since 2020, developed by the TON Foundation and community. Its architecture pairs a masterchain with workchains and dynamic sharding; the native coin is Toncoin.

TON (The Open Network) is a layer-1 (L1) blockchain that the Telegram team originally designed as the Telegram Open Network, now developed by the independent TON Foundation and community.
A short history
The project was built in 2018–2020 by Telegram developers led by Nikolai and Pavel Durov. After the 2020 settlement with the U.S. SEC, Telegram stepped back from direct involvement, and the code and roadmap passed to the open community and the TON Foundation. Today Telegram is a major partner and integration point, but not the network’s operator.
Architecture
- Masterchain — the coordinating chain that holds the network’s final state and validator set. See masterchain.
- Workchains — parallel chains for different purposes, up to 2^32 of them. See workchain.
- Dynamic sharding — workchains automatically split into shards as load grows and merge back when it drops, laying the groundwork for high throughput.
- Validators — nodes that confirm blocks via Proof-of-Stake. See validator.
Toncoin and tokens
The network’s native coin is Toncoin: it pays gas fees, is staked by validators, and serves as the ecosystem’s settlement asset. User tokens are issued under the jetton standard.
Telegram integration
TON is tightly tied to Telegram: built-in wallets, mini apps, Toncoin/Stars payments, and sales of usernames and gifts. Still, it is important to understand that Telegram is a partner and distribution channel — not the owner or operator of the blockchain.
