With a provable supply cap of 20,000,000, MWC is a scarce pure proof of work Mimblewimble based coin that enables 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.

The MWC network was launched in November 2019.

Since discovery in 2016, Mimblewimble technology has rarely been discussed and largely ignored. For example, Andrew Poelstra's 2016 presentation to SF Bitdevs, the topic's most viewed video, had less than 18,000 views three years later when MWC mainnet launched.

In the 2018 paper titled Aggregate Cash System: A Cryptographic Investigation of Mimblewimble, Fuchsbauer, et. al. concluded, "In this paper, we provide a provable-security analysis for Mimblewimble. We give a precise syntax and formal security definitions for an abstraction of Mimblewimble that we call an aggregate cash system. We then formally prove the security of Mimblewimble in this definitional framework. Our results imply in particular that two natural instantiations (with Pedersen commitments and Schnorr or BLS signatures) are provably secure against inflation and coin theft under standard assumptions."

There is a deficiency of high-quality information, plenty of ignorance and the result is significant asymmetric knowledge.

Nevertheless, MWC is the technologically superior ghost money.
