Pavel Durov: TON Now 10x Faster with Subsecond Finality

Pavel Durov announced on April 9 that the TON blockchain is now 10× faster. The upgrade went live on mainnet on April 10, 2026.

The update installs Catchain 2.0 as TON’s consensus layer. Block generation now targets 400-millisecond intervals, roughly six times faster than before. A new streaming layer delivers state updates to applications as they occur rather than waiting for the next block.

Before the upgrade, transaction finality typically exceeded five seconds. After the change, most users see finality in under one second.

Durov described the work as the first part of a seven-part plan called Make TON Great Again, or MTONGA. In a post he wrote: “The TON blockchain just got upgraded and is now 10× faster. Transactions are now instant, subsecond.” He identified a sixfold reduction in transaction fees as the next item on the roadmap but did not provide a timetable for the remaining phases.

For end users, faster finality affects in-chat payments, Mini Apps inside Telegram and trading applications that need quicker confirmations. Developers are being advised to move from polling the chain to using streaming APIs to receive lower-latency updates.

Network operators, wallet providers and app developers will need to adapt integrations to the faster block cadence and streaming data model. TON’s transaction fees are already low compared with many smart-contract platforms; the announced fee reduction aims to broaden use cases such as micropayments.
