By implementing MimbleWimble technology, Litecoin enhances privacy through various mechanisms. MimbleWimble allows for confidential transactions by combining multiple transactions into a single transaction, thereby obfuscating the transaction history. Additionally, it incorporates confidential addresses, ensuring that only the transacting parties have access to transaction details. Overall, the adoption of MimbleWimble technology in Litecoin significantly improves privacy by masking transaction amounts and increasing anonymity.
