I read about MimbleWimble Extension Blocks on a forum post. Then I tried it. It’s opt‑in privacy for Litecoin, done without changing the base protocol. That’s elegant engineering. You can send confidential transactions that only reveal the amount to the sender and receiver. It’s not as comprehensive as Monero, but it’s a significant step. Charlie Lee didn’t make a fuss; he just shipped it. That’s the Litecoin way. If you want to understand how that upgrade works under the hood, this technical summary is surprisingly readable.
