A computing device includes at least one processor configured to determine a retrieved secret share from each of at least two secret share storage devices or media that are retrieved from at least two of a plurality of shareholders. The at least one processor is also configured to determine whether each respective retrieved secret share is one of the plurality of secret shares that were generated based on whether the respective hash of the respective retrieved secret share matches any hash in the list of hashes of the plurality of secret shares within the metadata. The at least one processor is also configured to, in response to determining that each retrieved secret share is among the plurality of secret shares that were generated, attempt to reconstitute a secret using retrieved secret shares from the at least two secret share storage devices or media.

Secret splitting and metadata storage

A computing device includes at least one processor and at least one memory communicatively coupled to the at least one processor. The at least one processor is configured to determine a secret to be protected. The at least one processor is also configured to split the secret into a plurality of secret shares, at least a subset of which are required to reconstitute the secret. The at least one processor is also configured to transfer each secret share to a respective portable storage device or media for distribution to a respective shareholder. The at least one processor is also configured to generate metadata with at least a hash of each secret share, wherein the metadata is stored separate from the portable storage devices or media with the secret shares.

A system includes at least a first computing device, at a financial institution, configured to generate a currency request and apply first-level signature(s) to the currency request. A minting request is generated from the currency request and the first-level signature(s). The system also includes at least a second computing device, at a currency management department, configured to apply second-level signature(s) to the minting request to generate a signed minting request. The system also includes a third computing device, at a director's office, configured to apply third-level signature(s) to the signed minting request. The system also includes a plurality of network nodes, implementing a distributed ledger, configured to verify the first-level signature(s), the second-level signature(s), and the third-level signature(s); and mint the digital currency when the first-level signature(s), the second-level signature(s), and the third-level signature(s) are successfully verified.
