Abstract:
The disclosed embodiments include computerized systems and methods that generate secured distributed storage ledger structures, such as block-chain-based ledger structures, that facilitate event-based control of tracked assets. In one embodiment, an apparatus associated with a centralized authority of the secured distributed storage ledger may detect an occurrence of a triggering event, and may access and decrypt a set of rules hashed into the secured distributed storage ledger using a confidentially-held master cryptographic key. The apparatus may identify a rule associated with the detected event, and perform one or more operations consistent with the rule and involving at least one of assets tracked within the secured distributed storage ledger or an owner of a portion of the tracked assets.
