MimbleWimbleCoin (MWC) is a cryptocurrency that leverages the Mimblewimble protocol, which was first proposed in 2016 to enhance blockchain security and privacy. Named after a tongue-tying curse from the Harry Potter series, MimbleWimbleCoin emphasises anonymity and scalability by combining transactions and obfuscating information on the blockchain. MWC was introduced as a private untraceable currency that addresses some of Bitcoin's limitations, such as large storage requirement and lack of privacy. Through its unique architecture, Mimblewimble allows for smaller, more efficient blockchain size, along with confidential transactions where the amounts and sender-receiver details remain hidden. This distinct capability makes MWC particularly appealing for users prioritising privacy in their financial transactions.
