Systems and methods call a portion of an application programming interface (API) to access a portion of a current state data server of the blockchain computing platform (BCP) configured to perform virtual machine processing, the BCP comprising interconnected data processing nodes that include: a master ledger configured to store data asset records for master data received from decentralized application transactions performed via the interconnected data processing nodes, and peer nodes configured to provide cryptographic algorithmic trust control for master data management of the master data. The calling includes an API call to the current state data server to obtain current state results of certified transaction(s) in the master ledger, the certified transaction(s) having been certified at least in part via an endorsement protocol. Current state results of the certified transaction(s) are received from the current state server and displayed via a user interface of the user device.

Enhanced cryptographic blockchain computing platform systems facilitating trust control for certified master data management

A strategic master data management blockchain computing platform includes virtual machine(s) configured and deployed to execute an operating system of the blockchain computing platform across a virtual network, and a plurality of interconnected data processing nodes each comprising a plurality of functional layers, where the plurality of functional layers comprise an identity management access layer that is configured to establish a blockchain computing function. The blockchain computing function includes defining (a) role-based access control (RBAC) policies for access to master data management blockchain services, and (b) attribute-based access control (ABAC) time-based rules restricting access to portions of master data. The blockchain computing function also maintains a security framework that controls access to processing node resources across the virtual network.

Access layer systems of peer data processing nodes providing a security framework and trust controls

Systems and methods provide a blockchain strategic master data computing environment for master data management, where the strategic master data computing environment includes a peer-to-peer computing network comprising interconnected peer nodes collectively programmed to interoperate based at least in part on a computing environment coordination protocol, a portion or all of the plurality of peer nodes being configured to maintain a distributed and immutable master ledger storing data asset records of decentralized applications and collectively execute a set of trust protocols to securely write to the master ledger, where the trust protocols include a peer node interacting with other peer nodes within the peer-to-peer computing network to achieve consensus on identity of data assets referenced in a transaction and to endorse disposition of the transaction in the master ledger. The master ledger also stores smart contracts that include object codes, where the smart contracts are executed by peer node(s).
