Charlie Lee: Extension Blocks Concept Is Similar to Sidechains

23:10 Sunday , February 10th 2019
Charlie Lee, the founder of LTC, has updated a tweet, saying that "The extension blocks concept is similar to sidechains. Think of this as a MimbleWimble sidechain that is attached to the main chain using consensus via a softfork upgrade. You can opt-in by sending coins into the MW extension blocks and also send coins out back to the main chain."
