MSV (Marvrodi Salute Vison) is an innovative product in the DeFi era, using the concept of DeFi credit mining; MSV is issued using the POM (Proof of Mutual) mutual proof mechanism, with a total of 21 million pieces and a peak daily output of 7,200 pieces. MSV not only inherits the mutual aid concept from Marvrodi, but also adopts blockchain technology to create a new decentralized inclusive financial ecology. Through the knotted contract, MSV has created a new trust review mechanism in a decentralized and anonymous environment, expanded DeFi's credit granting capabilities with less collateral, and built a new form of community governance with MID as the system node. The scope of application of MSV includes DeFi credit mining under the POM consensus, knotted credit certificates, and payment tokens for MSV mutual aid ecological communities.
