What is a masternode in Minter?

Masternodes in Minter are the full nodes of the network, which have the right to perform validation and formation of blocks, for which their owners are rewarded. Anyone can create and run a full node and declare themselves a candidate as a validator. To participate in the validation of the network, however, you must have a sufficient general stake (own + delegated). The technical requirements and the principle of selecting masternodes, as well as the guideline on how to start operating a masternode in the test network, are available here https://docs.minter.network/#section/Validators
