Node Update TON 2026.08

Following the deployment of TON 2026.07 on August 4, the block production rate and other network metrics returned to their normal levels.

The next update, TON 2026.08, will activate collators on TON mainnet.

Currently, validators both assemble blocks from user transactions and validate them. After the update, these responsibilities will be separated. Dedicated collator nodes will assemble blocks, while validators will only verify them. This separation increases network throughput.

The collator architecture was introduced approximately one year ago in the Accelerator update. Its activation was scheduled for a period of significant load growth. The launch and continued development of native non-custodial wallet in Telegram are expected to increase network activity, making this the appropriate time to activate the architecture.

Since its initial implementation, Accelerator has been adapted to operate in the Sub-Second mode. TON 2026.08 can therefore be referred to as Sub-Second Accelerator.

The update is scheduled for August 17, 2026. All the details will be posted on the @tonstatus channel.

Enabling collators, particularly in in-memory mode, will increase the maximum TPS of a single shardchain.

As the next step, we plan to increase the maximum block size and other network limits. This is possible due to the new network layer introduced in TON 2026.05 and TON 2026.06, which reduced traffic between nodes. Increasing the limits will also lead to a proportional increase in the TPS of a single shardchain.
