  • Publication number: 20240004629
    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.
