⚡ Sub-Second Finality Is Coming to TON

TON Core is upgrading the blockchain to significantly increase block production speed, targeting sub-second user-perceived transaction finality, enabling end-to-end interactions in under 1 second.

Improving the blockchain is only part of the upgrade. Ecosystem apps need to adapt to deliver this experience to users.

Developers can start testing now and prepare for the upgrade.

What projects should do
🔹 Wallets & apps: switch to real-time Streaming API
🔹 Nodes & liteservers: update to versions supporting sub-second transaction finality
🔹 Indexers: ensure infrastructure handles higher block production without lag
