The Open Network suffered a 40-minute block production halt on June 1 due to a masterchain queue error.
The developers issued a quick fix requiring updates from only a few validators.
No user funds were lost and pending transactions were preserved. Though not unprecedented, this incident adds to TON’s history of high-throughput outages, including major disruptions in August 2024.

The Open Network (TON) briefly stopped block production on June 1 following a masterchain dispatch queue error that interrupted the blockchain’s operations for nearly 40 minutes.

The issue was first acknowledged at 12:51:00 UTC, with developers confirming that a “quick fix was released” and that only “a few master chain validators” needed to update their nodes to restore block production.

According to the TON team, no funds were affected and transactions submitted during the downtime remained intact.

High-speed blockchains like TON, Solana, and Sui Network, are known for their complexity and throughput, but they are particularly prone to short-term outages as validator logic becomes more intricate.

Latest Disruption not Sole Network Worry

Although 40 minutes may sound like a lot, TON has faced more severe disruptions. Last year, in August 2024, block production was halted twice in two days due to a rush of activity from users minting DOGS memecoins, overwhelming the network. However, it crashed again six hours later.

A second halt followed on August 28 at block 45,350,522, with service taking nearly six hours to restore.

Anyway, it’s a lot of setbacks. But all in all, institutional capital continues to flow into TON. In March 2025, TON secured a US$400M (AU$619M) raise led by Sequoia Capital, Draper Associates, CoinFund, and SkyBridge, according to a report from Fortune.

Telegram’s mini-app ecosystem heavily relies on TON, so therefore everyone is looking to have uninterrupted uptime 24/7. While some consider that ecosystem dead, the famous tap-to-earn project Notcoin is aiming to revive the glorious days by focusing on providing an actual, enjoyable gameplay and not just pure speculation.

Speaking of Telegram, the channel recently terminated one of the largest black markets in history, which laundered over AU$42B through Asia’s cyber scam economy.
