For 2 years, Litecoin social media directors have been mocking Solana’s blockchain failures. They needed to sacrifice their phrase this weekend because the Litecoin blockchain was hit with a denial of service and double spend assault.
Solana’s repeated suspensions elicited a smug smile from Litecoin. Not like Solana, Litecoin has no outages, based on its ongoing declaration.
On Saturday, that buzz died down. Litecoin has undoubtedly had outages and double-spend points.
A consensus bug in Litecoin’s privateness improve allowed attackers to mint invalid cash. Attackers made transactions quickly, attempting to double-spend as rapidly as attainable $LTC You should buy different digital property on cryptocurrency exchanges earlier than trustworthy miners cease promoting them.
That blockchain has been cut up. Finally, the miner rolled again the transaction, leading to roughly 32 minutes of efficient downtime.
Apparently, mining occasions throughout the assault had been unusually sluggish, in order that the community truly took greater than three hours in actual time to generate 13 substitute blocks, which generally include simply 32 minutes of transactions.
Regardless, the Litecoin Basis has since defined the 13 block reorganization to its personal followers.
No extra 100% uptime
Just some weeks in the past, Litecoin boasted a “100% uptime charge” and claimed that its blockchain had undergone “100% battle testing” and was “100% useful.”
Litecoin accounts spent 2024 and 2025 laughing at Solana’s issues with out fixing them themselves.
When Solana scheduled upkeep for a weekend in June 2025, Litecoin informed the Solana account, “This manner you’ll be able to schedule an outage for the weekend. Good determination.”
Solana responded to a different standing replace with one phrase: “Downtime.”
When the 2 networks signed a tongue-in-cheek cease-fire settlement later that month, the muse’s joke model had Litecoin promise “should you cease mocking Solana for six hours, Solana will preserve doing no matter you need.”
Mr. Solana’s personal folks refused to return the favor this weekend. Viv Norby, interim chief product officer on the Solana Basis, posted: “I’m not going to convey up the truth that @litecoin was dunked 1,000 occasions on Solana due to downtime, as a result of we’re higher than this.”

Litecoin and Solana downtime
The Litecoin vulnerability existed in MWEB, Litecoin’s Mimblewimble-based confidential transaction extension. Aurora Labs CEO Alex Shevchenko, whose chain ingests $LTC by way of $NEAR Intents doc exploits in actual time.
The attacker despatched a malformed MWEB pegout. The non-upgraded Litecoin mining nodes accepted it as legitimate and launched the artificial coin to the common Litecoin blockchain.
The attacker then bridges the proceeds by THORChain, $NEAR Supposed to alternate for ether.
Trustworthy miners operating the patched 0.21.5.4 consumer refused to dam the attacker. From there, the 2 forks competed.
After a number of hours, the patched chain lastly achieved stronger proof of labor, and the community reorganized blocks from 3,095,930 to three,095,943 into non-existence.
The time window for the reverse transaction was solely 32 minutes, however for the reason that hashing energy was cut up between trustworthy and abused nodes, it took practically 3 hours to truly reverse that quantity.
How are you spending your weekends? https://t.co/j4DzarJwnx

The patch has been stay on GitHub for a month
Haseeb Qureshi, managing associate at Dragonfly, stated that Litecoin’s double-spend bug was “identified, however the repair was not totally widespread.”
The truth is, the underlying consensus repair had been sitting in a personal GitHub department for about 30 days.
One safety researcher questioned the uneven disclosure window, which provides insiders a month-long head begin. Some main mining swimming pools apparently didn’t set up the general public launch in time.
For non-insiders, the general public launch of Litecoin Core 0.21.5.4 shipped on Saturday, shortly after the assault was launched.
