Peer Mountain is a decentralized data storage system. Users are able to store, manage and validate their private data as well as to share it with other users for personal or professional purposes. Peer Mountain uses an attestation engine that provides every peer in the system with a micropayment in PMTN every time they provide validation for another Peer Mountain entity. The PMTN token is an Ethereum-based (ER-20) cryptocurrency. It can be used to pay for invitations to the Peer Mountain ecosystem and for establishing trust in commercial transactions. Service providers make micropayments in PMTN every time they use Peer Mountain for identity verification and attestation engines receive PMTN for the use of their attestations.
