The Open Network (TON), the blockchain protocol closely linked to Telegram, experienced a brief but notable disruption on June 1 that halted block production. The issue was traced to a malfunction in the masterchain dispatch queue—a critical component responsible for coordinating validator activity.
TON’s development team reported the disruption at precisely 12:51 UTC and swiftly implemented a corrective patch that restored network operations within 40 minutes. According to the update, only a limited number of masterchain validators required adjustments to resume normal functionality.
In its official communication, TON reassured users that no digital assets were compromised during the outage. Transactions submitted while the network was down were successfully processed once the chain resumed.
The incident highlights the technical fragility of increasingly complex blockchain networks. As high-throughput chains like TON scale to support millions of users, brief service interruptions may become a recurring challenge.
TON Faces Ongoing Network Stability Challenges
TON’s growing ecosystem has positioned it as a serious contender in the blockchain space, largely due to its integration with Telegram. However, the June 1 outage is the latest in a series of setbacks for layer-1 chains pursuing both speed and scalability.
Although the latest disruption was swiftly resolved, it wasn’t the network’s first. In August 2024, TON experienced multiple outages tied to a surge in demand for the DOGS memecoin—a frenzy that repeatedly disrupted block production.
On August 27, validators encountered their first major bottleneck when block production stalled at workchain block 45,341,899. The network was overwhelmed by the sudden minting activity of DOGS tokens. Validators reset their nodes at 4:00 a.m. UTC to restore consensus, but by 5:30 a.m., the system faltered again.
The following day, block production ceased once more at block 45,350,522, again due to DOGS-related congestion. It took nearly six hours to restore full network function.
Despite Outages, TON Maintains Investor Momentum
Despite repeated technical setbacks, TON continues to attract significant investor attention. Its fast-expanding ecosystem, powered by Telegram’s massive user base, remains appealing to both retail users and institutional players.
In March 2025, the protocol secured $400 million in funding from top-tier venture capital firms including Sequoia Capital, Draper Associates, CoinFund, and SkyBridge—underscoring confidence in TON’s long-term vision despite recent hiccups.
Quick Facts
