Abstract
A blockchain-based secure customized catalog system includes a catalog customization system that receives a request to customize a first software catalog, and modifies the first software catalog to create a second software catalog that is customized for computing devices in a computing system. The catalog customization system then generates and broadcasts a first blockchain transaction that includes a smart contract having a second software catalog hash created from the second software catalog. A blockchain device receives the first blockchain transaction and, in response, provides the smart contract on a blockchain. When the blockchain device receives a second blockchain transaction broadcast by the computing system and including a hash value, it executes the smart contract. If the blockchain device determines that the execution of the smart contract indicates that the hash value matches the second software catalog hash, it transmits a second software catalog verification to the computing system.
