Is it possible to mine the coins?
Minter uses the consensus algorithm called DPoS (Delegated Proof-of-Stake), which is validated by providing a pledge (stake), including the funds that users delegate to the masternode. Rewards can be received by validators and BIP owners who delegate the coins to validators. The mechanism of distribution of rewards and examples are available in the white paper https://about.minter.network/Minter_White_Paper.pdf?v03
and documentation https://minter-go-node.readthedocs.io/en/latest/validators.html.
Note that currently, only the test network is active, the MNT coins do not have any real value, in the main network the base coin will be BIP, and meanwhile tests are being conducted by both the developers and the validators in order to fix everything and make the work as stable as possible to launch the main network.
