Summary

f2pool said Litecoin experienced abnormal network activity on April 25, 2026, including invalid MWEB (MimbleWimble Extension Block privacy feature) transactions and a temporary chain split. The mining pool said it detected the issue and continued mining on what it described as the valid chain under the correct rules. A temporary chain split means different parts of the network briefly followed different versions of the blockchain before reconverging, an event that can disrupt transaction confirmation until consensus is restored.

Terms & Concepts
  • MWEB: MimbleWimble Extension Block, a Litecoin feature designed to improve transaction privacy and fungibility.
  • Chain split: A situation where nodes or miners temporarily follow different versions of a blockchain, creating competing histories until one chain is accepted.
  • Mining pool: A group of miners that combine computing power to improve the chances of finding blocks and then share rewards.
