Abstract: Methods, systems, and devices for providing for trust in a distributed environment are disclosed. In a distributed environment, various devices may be remote to one another and may interact with one another via one or more operable connections. Through the operable connections, various communications may be exchanged. However, the operable connections may not natively support authentication of any particular device in the distributed system. Consequently, entities in the distributed system may not intrinsically trust that the communications received through the distributed environment are authentic. The entities of the system may mutually authenticate one another prior to trusting communications from the other entities. For example, in a scenario where a client wishes to access data hosted by a data source, the client and data source may go through a process of mutually authenticating one another. By doing so, a trusted environment may be established.

Abstract: Client machines, whether consumer or Enterprise, are notified of software updates using a decentralized, peer-to-peer blockchain infrastructure. Any software update is written to a block of data and distributed to blockchain nodes associated with a blockchain network. A smart contract, executed by any of the blockchain nodes, causes the corresponding blockchain node to notify specific client machines of the block of data recording the software update. The client machines contact the blockchain node and request the software update written to the block of data. The blockchain node retrieves and sends the software update written to the block of data. When the client machines receive the software update, the client machines apply or install the software update to improve their computer functioning.
