Disclosed herein are systems and methods for a system for authorizing proxy number token requests. The system may comprise a memory storing instructions and at least one processor configured to execute instructions to perform operations. These operations may comprise receiving a first request to use a proxy number token to complete a first action associated with a first entity; authorizing the first request; receiving a second request to use the proxy number token to complete a second action associated with a second entity; determining a modifiable relationship data binding associated with the first and second entities, the modifiable relationship data binding comprising multiple parameters; determining that the second request satisfies the parameters; and authorizing the second request based on a determination that the second request satisfies the parameters.

The instant disclosure illustrates how the privacy and security of activities occurring on distributed ledger-based networks (DLNs) can be enhanced with the use of zero-knowledge proofs (ZKPs) that can be used to verify the validity of at least some aspects of the activities without private information related to the activities necessarily being revealed publicly. Methods and systems that are directed at facilitating the tracking and recovery of assets stolen on ZKP-enabled DLNs while preserving the confidentiality of the tokens are presented herein.

A platform implementing a two-tier tokenization process to build a digital asset pool at a server. An application builds the digital asset pool, initializes general asset tokens to represent pro-rata ownership interests in a general pool of assets, and uses general asset tokens to create specific asset tokens to represent ownership interests in specific assets from that pool that a user of the platform selects, from a remote device in communication with the server, from the general pool. General asset tokens offered to eligible retail and/or institutional investors generate funding to build the asset pool. Owners of general asset tokens are periodically offered, by the server, the option to select portions of specific assets from the general asset pool, and create through the two-tier tokenization process, shares of specific asset tokens, subject to the technical protocols, ownership concentration limits, and bidding and allocation schema established by the present platform.

Provided is a system and method for creating, maintaining and tracking a cryptographic digital asset tied to physical asset, including creating a digital asset file representative of a respective physical asset; initializing a digital asset generator to create a blockchain-enabled NFT having a unique digital asset ID code; linking the unique digital asset ID code with a unique user ID code which is associated with the first party; creating a first transaction block in a distributed blockchain ledger to record possession with the first party; receiving an asset transfer request to transfer the digital asset and physical asset to a second party; verifying a second unique user ID code; linking the cryptographic digital asset with the second unique user ID code; and creating a second transaction block in the distributed blockchain ledger for recordation of the transfer of possession from the first party to the second party.

Methods, apparatus, and system to provide access to a blockchain computer system as a service to a non-blockchain computer system through an application programming interface, wherein the application programming interface is configured through a portal computer and wherein application programming interface calls are implemented by an application programming interface processing computer.

Systems and methods for offering and purchasing tokenized securities on a blockchain platform meeting current and future federal, state, and offering and holding entity rules and regulations. Tokenized securities purchased during or after the tokenized securities offering are tradable on a secondary market. The server computer of the tokenized securities provides an automated transfer capability for tokenized securities holders.

Devices, systems, and methods are provided for blockchain tokens and ledger for medical and dental transactions. A method may include determining a cost of a healthcare service provided to a patient by a healthcare provider; accessing a blockchain digital ledger; identifying a digital wallet of the patient stored using the blockchain digital ledger; identifying, a digital token stored in the digital wallet, the digital token restricted to payment for the healthcare service and issued by an insurer; transferring, based on a smart contract of the blockchain digital ledger, the digital token from the first digital wallet of the patient to the healthcare provider; determining a difference between the cost and a pecuniary amount provided by the digital token; and generating a bill for the patient, the bill indicating that the patient owes the difference to the healthcare provider.

A user operating an endpoint app chooses to obtain a blockchain-based asset on a target blockchain. The user does not have blockchain transaction credentials for the target blockchain, but does have blockchain transaction credentials for a source blockchain. The endpoint app hierarchically creates target blockchain transaction credentials for the user, using an initial seed of entropy that was used to create the user’s source blockchain transaction credentials. A backend component automatically obtains an amount of target blockchain cryptocurrency sufficient to obtain the blockchain-based asset on the target blockchain, in exchange for source blockchain cryptocurrency of the user. The obtained target blockchain cryptocurrency and the hierarchically created target blockchain transaction credentials are used to automatically obtain the blockchain-based asset on the target blockchain, such that once the transaction is completed, the obtained blockchain-based asset is registered to the address of the user’s hierarchically created target blockchain transaction credentials.

Methods and systems are presented for providing a framework for facilitating event-based triggers of auxiliary cryptocurrency transactions via a Layer 2 cryptocurrency computer network. A transaction system detects a triggering event associated with a first digital wallet. Based on the detected event, the transaction system determines an auxiliary cryptocurrency transaction for the first digital wallet. Without recording the auxiliary cryptocurrency transaction in a public ledger associated with the cryptocurrency, the transaction system conducts the auxiliary cryptocurrency transaction via the Layer 2 cryptocurrency computer network via one or more payment channels established by computer nodes in the Layer 2 cryptocurrency computer network.

Disclosed are various embodiments for using custodial systems to maintain ownership of digital assets and facilitate transfers of digital assets between individuals. To facilitate a user taking possession of a digital asset, the custodial system could update an owner identifier for a digital asset in an asset ledger to include a public key of an asset custodian, the public key of the asset custodian indicating that the asset custodian is the owner of the digital asset. The custodial system could then provide a verifiable credential to an identity wallet, the verifiable credential being linked to the digital asset in the digital asset ledger. Subsequently, the custodial system could create an asset record that stores an owner identifier in association with an asset identifier for the digital asset, the owner identifier representing a user of the identity wallet.
