Blockchain-based personal location and messenger device and system using decentralized mesh networking

A personal locational and messenger device and system, consisting of:

• A) a decentralized mesh network;
• B) a blockchain, said blockchain is an immutable blockchain system;
• and
• C) a device operatively associated with a non-transitory computer readable medium, said blockchain is associated with said decentralized mesh network to define a personal location platform and a messenger platform, said decentralized mesh network has a plurality of nodes operatively associated to each other and a full mesh topology or a partial mesh topology, said decentralized mesh network and said blockchain provide an immutable and decentralized platform, said device communicates through said decentralized mesh network, said blockchain stores a personal location and emergency messages provided by users, said decentralized mesh network disseminates said personal location and said emergency messages, and said device communicates through wireless networking infrastructures or through a satellite communication infrastructure, said device also communicates through a cellular network, said device communicates through said decentralized mesh network when said wireless networking infrastructures and said cellular network are not available, said users send respective emergency messages to a respective recipient through said device by said decentralized mesh network, when said users designate said recipient, only respective said recipient is able to view said emergency message or said personal location, and when said device is in a low-fidelity networking range, said device uses pre-composed emergency messages defined by said users, said pre-composed emergency messages are available for selection at the time of a positional location dissemination, said satellite communication infrastructure is a Global Positioning System/Global Navigation Satellite System, further characterized to work in rural and remote locations, further having a peer to peer network.
