The full name of VCM project is VolunChainMax, which is operated by the practitioner charity team to carry out all the projects. VCM mainly aims at creating a public service platform for sans frontieres physical therapy. By using the technical features of block chain, it issues VolunChainMax Token to make public and transparent the progress of public welfare, and combines the services of the platform itself. At present, the extension of the Internet to the traditional field makes the connection between the upstream and downstream links of the public welfare industry increasingly close, whose essence is the relationship between the supply and demand of relief and assistance and recipients. Public welfare charity is the lofty spiritual quality and moral pursuit of mankind. It is essentially the third distribution of social resources and wealth.
