Mainnet validators and node owners
A scheduled network update is planned for July 13.

We ask that operators schedule a time on Monday, July 13 at 10:00 UTC to perform the software update.

This update is mandatory for both validators and full node owners and will include important changes to improve performance and stability.

On July 15, we expect to propose the corresponding network configuration changes for voting.

Mainnet shard processing slowdown

Block production and message processing in workchain shards are currently experiencing a slowdown.

The TON Core team is aware of this issue and is working to resolve it.

Mainnet block production on shard chains has resumed

From approximately 09:30 UTC to 11:12 UTC, there was a significant slowdown in the block rate and message processing on shardchains. Operations have now resumed.

We are monitoring the network and investigating the incident.

Mainnet validators and node owners

The scheduled network update planned for July 13, as well as the corresponding vote on network configuration changes planned for July 15, have been postponed.

We will communicate the new deadlines soon.

Mainnet validators and node owners

Please schedule a time on Wednesday, July 15, at 11:00 UTC (tomorrow) to perform the software update. Furthermore, validators will be asked to vote on adjusting the technical network operating parameters.

This update is mandatory for both validators and full node owners. The update will include important changes to improve performance and stability.

Mainnet validators

Please take part in the voting for network config adjustment.

In order to improve the stability of the network, we kindly ask that you vote in favor of temporarily reducing the maximum number of shardchains from 16 to 4. This reduction will not affect the performance of the blockchain or the user experience under the current organic load. This reduction is temporary, and we will increase this setting in an upcoming update.

If you use mytonctrl, please vote for proposal via

You may vote before or after the update to the latest release [v2026.06].

Attention Mainnet validators:

On Wednesday, July 22, starting from 5:30 UTC, we ask that validators set aside time to vote on two proposals.

Config 8: Increase the network version to 15. This will enable changes to improve network stability. More information can be found here.

Config 30: Increase the protocol version to 2. This will enable Plumtree broadcasts feature that was included in [2026.06] upgrade.

The proposals to update Config 8 and Config 30 have passed.

The network is now using both the new Plumtree broadcast mechanism and the legacy broadcast mechanism simultaneously.

In approximately one week, we will ask operators to update their validators and nodes. After the update, the network will use only Plumtree broadcasts.

Based on our estimates, this should reduce inbound node traffic by approximately 4× and outbound traffic by 2×. It should also significantly improve synchronization and connectivity for nodes and validators.

Mainnet node owners

Please update your nodes to the 2026.06 release now. See https://t.me/tonstatus/225.

Failure to update your nodes will result in loss of network synchronization once legacy broadcasts are disabled in approximately one week.
