⚡️ Sub-Second Mainnet Activation Starts Now

TON Core has announced the mainnet rollout of the Sub-Second upgrade.

This is a consensus upgrade designed to move TON toward sub-second finality and bring on-chain UX closer to Web2 responsiveness.

Rollout plan:

📅 March 31: Validators upgrade nodes to the version supporting the latest consensus changes

📅 April 2: Validators vote to activate the new consensus on the basechain and enable a moderate block rate increase

📅 April 7: Validators vote to fully activate fast consensus on both the basechain and masterchain
