With a provable supply cap of 20,000,000, MWC is a scarce pure proof of work Mimblewimble based coin designed to enable greater network scalability, privacy and fungibility than legacy blockchain protocols. All transactions on the base layer use Greg Maxwell's Coin Join with his Confidential Transactions and signature aggregation.

Three main properties of MWC transactions increase their privacy. All transactions on the base layer are CoinJoined with Confidential Transactions and signature aggregation. Consequently, there are no addresses, transaction amounts or intermediary inputs and outputs in blocks and all transactions are indistinguishable from one another.
