hey,
I am selling the shared Masternode platform that used to be called MyNode.rocks. you can find an informative explanation here
https://www.youtube.com/watch?v=oTtmK_A1DSQ&t=18sthe code is written in java spring, and some hibernate liquibase
the platform allows currently for shared Masternodes and personally owned masternodes when someone holds 100% of a single masternode
