Mainnet Moves to Sub-Second Finality Following Catchain 2.0

The TON mainnet has introduced sub-second finality, enabled by Catchain 2.0, reducing confirmation times to near-instant execution, with block production increasing roughly 6× and improving throughput, supporting Telegram’s ecosystem of over 1 billion users.

TON Mainnet Achieves Sub-Second Finality

The update increases block generation by approximately 6×, allowing the network to process transactions faster and finalize them in under 1 second. According to official statements, this improvement removes a key bottleneck that previously limited user experience in applications requiring immediate feedback.

Impact on User Experience and Network Economics

Improved Transaction Speeds

Pavel Durov highlighted that the network is now significantly faster, with transaction speeds improving by up to 10×. He described the rollout as the first step in a broader plan to enhance TON’s infrastructure and efficiency.

Increased Validator Rewards

The upgrade also affects network economics, with increased block production leading to higher validator rewards and strengthening incentives for staking participation. Durov indicated that upcoming steps include reducing transaction fees by a factor of 6, further improving accessibility for users and developers.

Competing in High-Throughput Blockchain Infrastructure

TON continues to function as the blockchain layer supporting Telegram’s growing ecosystem of mini apps, payments, and digital services. With more than 1 billion users, reducing transaction time directly impacts usability and adoption. Faster finality allows payments to feel similar to sending a message, while trading and in-app interactions execute without noticeable delay.
