Less than 30% of Litecoin nodes have installed patch for double-spending bug
By

Summary
In early 2026, a hacker attempted a double-spend attack on Litecoin, which was thwarted by an emergency 13-block reorganization. Developers released patches to fix the vulnerability, but nearly two months later, less than 30% of Litecoin network nodes have installed the update. The majority of non-mining nodes remain unpatched, leaving the network potentially vulnerable to similar attacks.

· 3 pulledEarlier this year, a hacker tried to double-spend litecoin (LTC) before an emergency, 13-block reorganization thwarted the attack.
The patch has been available for free download for nearly two months. Nonetheless, of the nodes tracked by a major monitoring service, less than 30% are running up-to-date software that would reject the type of transactions behind April's double-spending attempt.
Sadly, the largest cohort of node operators have not applied the fix.
