TON Network Stability Restored After 40-Minute Block Production Interruption

• Block production on TON paused briefly on June 1 due to a masterchain dispatch queue processing error.
• Validator consensus restored fast with a patch; a few nodes needed only 40 minutes for recovery.

The Open Network (TON), linked to Telegram, faced a temporary service interruption on June 1, 2025. Block production came to a halt due to an issue in the masterchain dispatch queue, a problem developers resolved within 40 minutes. 

The development team rolled out a targeted patch that restored validator consensus and resumed activity. This brief service freeze did not affect any user funds, according to TON’s official update. The technical team said the solution only required updates to a few masterchain validators, making the recovery process swift. 

A full technical breakdown of the event is expected to be shared by the team in the coming days. During the pause, network users did not suffer asset losses, though block creation was momentarily interrupted. TON developers attributed the incident to a misstep in processing the masterchain dispatch queue.

TON Faced Multiple Crashes Since 2023

This is not the first time TON has encountered service disruptions. In December 2023, the network’s performance dropped dramatically after a spike in TON20 transactions. The transaction rate, which normally handles up to 100,000 transactions per second, fell to below one per second. This failure was attributed to validators relying on underpowered hardware.

Following the December event, developers responded with a patch and also encouraged the community to upgrade hardware specifications. Warnings were issued that those failing to meet minimum performance levels would face penalties to prevent such occurrences in the future.

In August 2024, two separate outages further tested the reliability of TON. On August 27, block production stopped at block 45,341,899 due to overwhelming traffic caused by the DOGS memecoin launch. It resumed only after validators coordinated a node reset. A second incident hit the next day, August 28, lasting roughly six hours before block 45,350,522 brought production back online.

TON’s Resilience Amid Technical Challenges

Despite the technical challenges, TON has continued to attract support and attention. In March 2025, the project secured $400 million in new funding from well-known investors such as Sequoia Capital, CoinFund, Draper Associates, and SkyBridge. This influx of capital shows that confidence in the platform remains intact among institutional backers.

The team has also made moves to strengthen its leadership. Former Visa executive Nikola Plecas joined the project as vice president of payments. He is now tasked with managing payment systems, scaling services, and ensuring financial and legal compliance for the network, which serves over 1 billion customers.

Outages of this nature are not exclusive to TON. Over the past year, platforms like Solana and Sui have faced similar disruptions, usually stemming from validator consensus breakdowns or poorly handled code during network surges.
