Abstract: A method executed by a computing entity includes obtaining, in accordance with a securely passing process, control over a secure first token representing a first pending transaction associated with a transaction item. The method further includes obtaining a selection of a first subset of instant assets of a set of candidate instant assets that may be utilized to subsequently provide conversion of the selected contingent asset to complete the first pending transaction. The method further includes generating an updated secure first token in accordance with the securely passing process to represent the selection of the first subset of instant assets of the set of candidate instant assets to subsequently provide the conversion of the selected contingent asset to complete the first pending transaction.

Abstract: A method includes a validation computer receiving an authorization request message comprising a user state and a user proof from a user device. The user state comprises first and second user state elements. The user proof comprises first, second, and third user proof elements. The validation computer computes a first verification value by multiplying the first user proof element raised to the power of the second user state element, and the second user proof element raised to the power of the first user state element. The computer computes a second verification value by raising the second user proof element to the power of the second user state element. The computer compares the first verification value to a first accumulated state element of an accumulated state. The compares the second verification value to a second accumulated state element. The validation computer authorizes the authorization request message based on the comparison steps.

Abstract: A system includes a memory and a processor configured to execute computer instructions stored in the memory that when executed cause the system to perform operations. The operations include receiving transaction data associated with a transaction via a transaction component. The operations include incorporating at least a portion of the transaction data into a security process associated with challenge-response authentication of a data block for the transaction data. The data block includes cryptographic hash data for another data block in a blockchain associated with the data block. The operations include validating the data block associated with the blockchain based on the security process.

Abstract: On a FinTech platform, integrated blockchain networks and Interplanetary file system (IPFS) technologies provide daily servicing and reporting activities to users of the Platform. Users, such as stakeholders, customers and financial institutions, interact with the Integrated Platform through both private and public networks without a middleman. A platform user uploads information associated with a physical asset, such as a mortgage/deed, loan information, or the like, to the platform. The platform records the uploaded information, simultaneously, to a private blockchain and an IPFS of the platform. A collateralized non-fungible token (cNFT) is generated to represent the physical asset and is also recorded to the private blockchain and the IPFS. To transfer ownership external to the platform, the cNFT is converted to a public cNFT and migrated to a public blockchain.

Abstract: A method for consumer-initiated transactions with encrypted tokens includes: storing a first cryptographic key pair comprising an account public key and an account private key, a merchant public key, an account token associated with a transaction account, an account identifier, and an issuing institution identifier; receiving transaction data for a proposed payment transaction including a transaction amount; generating a transaction order including the transaction data; generating a cryptographic checksum for the generated transaction order; generating a digital signature over the cryptographic checksum using the account private key; generating a payment token including the issuing institution identifier, the account identifier, the transaction amount, and the account token; encrypting the payment token using the account private key; and transmitting the encrypted payment token and signed cryptographic checksum to a point of sale device.
