The Open Network (TON), a layer-1 blockchain closely integrated with the Telegram messaging platform, experienced a brief service interruption on June 1, halting block production for approximately 40 minutes. The disruption was caused by an error in the masterchain dispatch queue, which was quickly identified and resolved by the development team.
Block Production Restored Within 40 Minutes
The TON team announced the issue at 12:51:00 UTC, with functionality fully restored less than an hour later. According to an official update, “A quick fix was released, and updating only a few master chain validators was sufficient to resume block production.”
No funds were lost, and transactions submitted during the downtime were processed once the network was restored, the team reassured users.
This incident highlights the increasing technical complexity of high-speed blockchain networks, which may lead to occasional short-term outages even in highly robust systems.
Previous Outages Linked to DOGS Memecoin Activity
This is not the first time TON has experienced outages. In August 2024, the network faced multiple disruptions due to extreme demand for the DOGS memecoin, which resulted in network congestion and halted block production.
- On August 27, block production stopped at workchain block 45,341,899, lasting several hours before validators restored consensus at 4:00 AM UTC.
- Functionality briefly returned at 5:30 AM UTC, but high minting traffic caused the network to crash again later that day.
- A second outage occurred on August 28, stopping block production at block 45,350,522. This downtime lasted approximately six hours.
Ongoing Growth Despite Network Challenges
Despite these technical hiccups, TON continues to see strong traction from both retail and institutional investors. In March 2025, the network secured $400 million in funding from leading venture firms, including Sequoia Capital, Draper Associates, CoinFund, and SkyBridge.
TON’s resilience and rapid recovery times demonstrate its growing maturity, even as usage scales and infrastructure faces occasional stress.
Conclusion
The June 1 outage serves as a reminder of the challenges facing advanced blockchain systems. However, TON’s quick response, secure transaction handling, and ongoing institutional backing suggest a positive long-term outlook. As blockchain adoption grows, maintaining uptime and performance under pressure will be key to sustaining user trust and market value.
