Litecoin Network Faces Reorg After MWEB Exploit
- On April 25, Litecoin experienced a 13-block reorganization due to an exploit of an MWEB zero-day bug.
- The reorg covered approximately 32 minutes of chain history, affecting major mining pools.
- Developers had privately patched the MWEB flaw in March, but the fix was not widely implemented by miners and nodes.
- A coordinated effort by mining pools reversed invalid transactions without loss of valid ones.
- The incident exposed coordination gaps between developers and the broader miner and node operator base.
Litecoin’s network suffered a significant disruption due to an exploit targeting its MWEB layer, leading to a temporary reorganization of blocks. Despite prior private patching efforts, the vulnerability was not fully communicated or adopted across all nodes, allowing attackers to exploit it briefly before corrective measures were taken. The event highlighted existing communication challenges within the network infrastructure. (Source)
