TON Blockchain Boosts Speed with Catchain 2.0 Upgrade

The TON blockchain has undergone a significant transformation with the activation of the Catchain 2.0 upgrade, which has been in development for some time. This major revision is designed to improve the performance of the network by reducing block times and bringing transaction confirmations down to approximately one second.

The upgrade represents a significant technical leap forward for the TON blockchain, with the implementation of the QUIC transport protocol, a modern networking standard originally developed by Google, accelerating communication between validator nodes. As a result, block production times have been reduced from 2.5 seconds to approximately 400 milliseconds, while transaction finality now settles in around one second.

The faster block cadence also carries implications for validators, as blocks are now produced more frequently, resulting in increased validator staking rewards due to the higher block production rate. This change could make TON staking more attractive relative to competing proof-of-stake networks.
