The Open Network (TON), a layer-1 blockchain closely integrated with the Telegram messaging platform, encountered a brief operational disruption on June 1, 2025. The incident, attributed to an error in the masterchain dispatch queue, halted block production for approximately 40 minutes. TON’s development team promptly addressed the issue, releasing a fix that required updates to only a few master chain validators, thereby resuming normal network operations.
Importantly, the TON Foundation confirmed that no user funds were compromised during the outage, and all transactions submitted during the downtime remained secure.
This event follows previous network challenges faced by TON, notably in August 2024, when the network experienced multiple outages due to the overwhelming demand from the DOGS memecoin minting frenzy. These incidents underscore the complexities and scalability challenges inherent in high-throughput blockchain networks.
Despite these technical hurdles, TON continues to attract significant institutional investment. In March 2025, the TON Foundation announced that it had secured over $400 million from prominent venture capital firms, including Sequoia Capital, Draper Associates, CoinFund, and SkyBridge. This substantial investment reflects growing confidence in TON’s potential to serve as a foundational infrastructure for decentralized applications within the Telegram ecosystem.
