A method and system of providing verification of information of a user relating to an attestation transaction is provided, and includes sending a request for information of the user, wherein the information has been previously attested to in an attestation transaction stored within a centralized or distributed ledger at an attestation address; receiving at a processor associated with a verifier the information of the user; sending a cryptographic challenge nonce; receiving at the processor associated with the verifier the cryptographic challenge nonce signed by the user's private key; verifying user identity with the cryptographic challenge nonce signed by the user's private key; deriving a public attest key by using the information of the user; deriving an attestation address using the public attest key; and verifying the existence of the attestation transaction at the attestation address in the centralized or distributed ledger.

Methods and systems of providing verification of information using a centralized or distributed ledger

Systems and methods for identity verification to provide access to restricted goods or services. A first device may receive, from a second device operated on behalf of a user, a first request to purchase a restricted good or service. The first device may transmit, to the second device responsive to the first request, a second request comprising an identification of information of the user, and an identification of validation system; and may receive the requested information of the user. The first device may generate an attestation key comprising a hash of the requested information of the user and the identification of the validation system; and may determine that a record in a centralized or distributed ledger at an address corresponding to the attestation key is associated with a non-zero transaction value. Responsive to the determination, the first device may provide the restricted good or service to the user.

Eligibility for access to restricted goods and services using zero-knowledge proofs

A computer-implemented method for managing cryptocurrency is disclosed. A plurality of users are provided with an in-marketplace wallet suitable for storing linked digital tokens that are linked in value to cryptocurrency tokens and are required to transact on a digital marketplace platform. A cryptocurrency reserve is provided for storing cryptocurrency tokens. Responsive to a user purchasing linked digital tokens from a marketplace store, linked digital tokens are transferred to the in-marketplace wallet an equivalent value of cryptocurrency tokens are transferred to the cryptocurrency reserve. Responsive to a user withdrawing a number of linked digital tokens from the in-marketplace wallet, the desired number of linked digital tokens are removed from the user's in-marketplace wallet and an equivalent value of cryptocurrency tokens are transferred from the cryptocurrency reserve to an out-of-marketplace wallet of the user for storing cryptocurrency tokens outside of the marketplace platform.

Cryptocurrency system

Systems and methods for providing identity verification services to users by providing a staking mechanism to incentivize participants in an identity verification system to be truthful and accurate and determining validator accuracy and associated setting of fees for using validator attestations to create an efficient, private and secure system.

Systems and methods for providing identity verification services

Methods and systems for establishing a chain of relationships are disclosed. An identity verification platform receives a first request for registration comprising an identification of a first user, identification of an entity, and a relationship between the first user and the entity; verifies the identity of the first user and the relationship between the first user and the entity; and verifies that the entity is legitimate. Once a relationship between a first individual, invited by the first user, and the entity is confirmed, the platform creates a custom badge representing the relationship between the first individual and the entity for display on the entity's website. The platform receives an identification of a selection by an end user of the custom badge and, responsive to receiving the identification of the selection, renders, on a domain controlled by the identity verification platform, a verification that the relationship between the first individual and the entity is valid.

User ID codes for online verification

Providing verification of the identity of a digital entity may include including receiving information and a public key of the digital entity, the information having been previously attested to in an attestation transaction stored within a centralized or distributed ledger at an attestation address, the centralized or distributed ledger providing a record of transactions. The system may derive an attestation address using the information and the public key of the digital entity. The system may verify the existence of the attestation transaction at the attestation address in the centralized or distributed ledger and verify that the attestation transaction has not been revoked. The processor associated with the user may receive a cryptographic challenge nonce signed by the digital entity's private key; and may verify the digital entity's identity with the cryptographic challenge nonce signed by the digital entity's key.

Disclosed is a method for providing fraud protection and transaction tracing for gift card accounts through use of a public blockchain ledger. Digital gift cards are associated with tokens which are passed between user accounts. The users do not obtain direct access to the debit codes assigned to the gift cards and are instead provided with variable authentication codes for use in merchant purchases. The variable authentication code is used by a merchant to obtain a reference to an actual debit code held by a web server. Numerous types of transactions are published to the blockchain ledger including initial purchases, reserving/claiming of debit codes, transfers of tokens between accounts, and depleting of gift card value associated with a token. Transactions published to the blockchain occur substantially simultaneously with a merchant purchase such that users may look up gift card values at any time to be assured each gift card is valid.

System and method for establishing a public ledger for gift card transactions

Methods and apparatus for providing authentication of information of a user are described. Upon validation of this information, a first hash function is applied to the user's information to create a hash. A public attest key is generated by combining the hash of the user's information with one or more public keys. An attestation address is generated based on the public attest key. A signed transaction which includes the attest key is communicated for storage in a centralized or distributed ledger at the attestation address.

Methods and apparatus for providing attestation of information using a centralized or distributed ledger

Various of the disclosed embodiments generally contemplate computer-implemented systems and methods for selecting an electronic or virtual gift card from among a plurality of possible gift cards or gift card issuers. Various of the embodiments may match and rank the gift cards according to a gift card recipient's characteristics, and possibly to the electronic or virtual gift card itself. Certain embodiments also contemplate the selection of physical gift cards selection, matching, and ranking aspects of the invention. Various methods for operating a gift card business using certain of the embodiments are also disclosed.

Systems and methods for digital gift card selection

Disclosed herein are certain embodiments of systems and methods for standardizing a plurality of digital wallet credits, into one digital wallet system. Expenditures of merchant issued credit stored in digital wallets are supported by tokenization of assets. Assets are encoded and represented by currencies tracked on public ledgers. Data is mined from the public ledger, decoded, and presented to users with a unified interface which allows users to view balances at any time of all digital wallets in their possession.
