Abstract: Various embodiments can implement a multi-system or node architecture that can be deployed on-demand and augment existing systems with pre-configured nodes that can be installed within existing architecture. The multi-node architecture is flexible for integration into many systems and can also stand alone to provide data validation and assurance. Various embodiments of the multi-node architecture enable private and public distributed ledgers (e.g., blockchains) that enhance security, enhance confidentiality, and eliminate the need to trust the provider/hosts of the data validation information and/or the hosts of the confidential information.
