KoinlyticsThe Open Network started as Telegram's own blockchain project in 2018, was abandoned after SEC pressure in 2020, and was resurrected by the community as TON. In 2024 it became one of the most-used chains globally, powered almost entirely by Telegram's 900 million users clicking into wallet mini-apps.
Architecture: sharding by design
TON is built as a hierarchy: a masterchain coordinates workchains, and workchains can be split into shardchains dynamically as load grows. In theory, TON can support billions of transactions per second by adding shards. In practice, one workchain (the base) handles almost all activity today.
Actors, not accounts
TON uses the actor model. Every smart contract is an actor with its own state and message queue. Contracts communicate asynchronously via messages, not synchronous calls like EVM. This changes what patterns work: no reentrancy the way Ethereum has it, but harder to compose contracts across shards.
Why it exploded in 2024
- Telegram integrated the TON wallet as a native mini-app. 300 million+ Telegram users now have a self-custodial wallet one tap away.
- Notcoin, Hamster Kombat, and other tap-to-earn games onboarded tens of millions to hold TON tokens.
- Toncoin (TON) fees are cents; transactions confirm in seconds.
- USDT went native on TON in April 2024, bringing serious stablecoin liquidity.
The catches
Developer tools are still catching up (FunC / Tact are less familiar than Solidity). Cross-chain bridging to TON is thinner than to major EVM chains. Regulatory questions remain because of the historical Telegram connection.
