▎ 摘　　要

NOVELTY - The system (100) has a set of nodes (130) in electronic communication, where the nodes include a first primary node (131) operable by a first user, a second primary node operable by a second user, and a secondary node (132). A secondary node comprises an unmanned sensor that is provided to record sensor data. A blockchain distributed ledger (112) is used to confirm and catalog data for the decentralized applications. A message data is generated by the first primary node and addressed to the secondary primary node, and is added to the distributed ledger via a consensus mechanism performed by the decentralized applications. The first primary node, second primary node, and secondary node is powered by a rechargeable power source that is recharged by a power charging module having a photovoltaic cell. USE - Decentralized information system for employing exponential technologies in mission information systems. Uses include but are not limited to distributed ledger technology, edge computing, solar power and Internet of Things (IoT) to provide an assured, secure system for operational, mission command and mission critical information system. ADVANTAGE - The method enables utilizing a permissioned blockchain or permissioned directed acyclic graph (DAG) to provide additional security and speed transactions while reducing a computation load of software on the nodes. The method allows a decentralized information system to employ a blockchain distributed ledger along with edge computing, advanced wireless networking and emerging power generation and storage capabilities, such as solar cells and graphene batteries, to provide a foundation for a decentralized, internet-of-things (IoT-like) mission information system. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a decentralized information system. 100Decentralized information system 112Blockchain distributed ledger 130Node 131First primary node 132Secondary node
