TON Status

Mainnet Validators

Voting and the upgrade have been postponed from April 7 to April 8 at 14:00 UTC.

Additional time has been allocated for infrastructure preparations by certain validators and services, as well as for additional preparation of the TON Core development team.

Mainnet validators

The proposals for the first stage of the migration to the TON Sub-Second regime have been accepted. Thank you for your support!

The mainnet basechain is already running on Catchain 2.0 with an 800 ms target block time. Services using streaming APIs, such as MyTONWallet, have already seen up to a 3x improvement in transaction UX speed. Services relying on older, more established APIs should continue to operate as usual.

The second and final stage of the migration, which will fully enable Catchain 2.0 on the masterchain and reduce block time to 400 ms, will begin on April 7. We would appreciate your support for this step as well.

⚠️ Please note that full activation of Catchain 2.0 consensus requires an additional open UDP port for ingress traffic on nodes actively participating in validation (full nodes and lite servers are not affected). Documentation on this will be published later today in this channel.

Mainnet Validators

Please ensure that your node is up-to-date (see "Target versions") and vote for proposal described above.

Mainnet validators

Tomorrow, April 2, at 8:00 UTC, we ask validators to set aside time to vote on two proposals:

— Bump the TVM version to 13. This fixes some logical issues in transaction execution and serialization (which does not affect real-world contract behavior) and allows faster than 1 block per second.

— Vote to activate Catchain 2.0 in the basechain, with a block time of 800 ms and a first-slot timeout of 1600 ms.

Due to the transition to the new consensus, and to prevent unjust penalties after the new consensus is activated, voting on fines in MyTONControl is disabled until April 20. Thank you for your attention to this matter.

Sub-Second mainnet activation timeline for validators

March 31 (today): Upgrade validator nodes to the version supporting the latest consensus changes.

April 2: Vote to activate the new consensus on the basechain and enable a moderate block rate increase.

April 7: First, vote to fully activate fast consensus on both the basechain and masterchain, and then upgrade validator nodes.

Mainnet Node Software Update [v2026.03]

Please update your node software (see "Target versions"):

Update with mytonctrl:

This upgrade is mandatory and will migrate celldb to celldb_v2 while enabling the fast serialization process as the default (which also reduces RAM usage). The upgrade also includes emulator improvements, improvements of traffic compression, introduces parallel validation (not yet enabled by default), and addresses various minor issues.

Scheduled voting on November 12

We are asking validators to schedule a time on Wednesday, November 12 at 10:00 UTC for network parameters voting.

There will be 3 proposals to vote.

1. First is related to upcoming release of Major Regulated Stablecoin coming to the TON Ecosystem and it requires upgrade of config contract. After this upgrade two config parameters, in particular -1024 and -1025 (previously unassigned and without any effect on network operation) will become governed by EQA_o6NFLu73wozeYNERTsW8lkU5OarbRbIkoNuWdy5SPDA_ address.

Code of upgraded config-contract is available here.

2. Second is related to activation TVM 12 (Config param 8). It will bring long-time requested developer friendly new bounce types and opcodes.

3. Third is related to BTC Teleport (Config param -90), new config will introduce alternative script path spending with taproot timelocked multisig on BTC side which will make it's operation safer under validator misbehaving.

Please be prepared.

Upgrade rate in mainnet reached 97%

TON Core thanks validators for quick updates and diligent node maintenance!
