A system for secure payment with electronic money using a mobile device, in particular using a non-secure mobile device (2) without a suitable security element, to the electronic money. In addition is a method for secure payment with electronic money as well as to the use of the method.

A system for transferring money includes an electronic communication device running an application for performing a number of tasks including enabling a sender to add a desired amount in a desired currency, provide necessary sender and receiver information including a contact information and unique ID of the receiver and create, encrypt and transfer a transaction information in form of blocks of a blockchain to a distributed blockchain network, having multiple computing nodes to store a portion of the blockchain. An electronic computing device associated with an authorized financial service provider, forming a computing node of the distributed blockchain network, allows to retrieve and decrypt the blocks containing the transaction information and verifies the unique ID and a unique PIN, which is generated by the application and sent to the receiver via the contact information given by the sender, submitted by the receiver for completing an instant cash transaction.

The disclosure relates to an improved technology protocol for a distributed cryptocurrency system with built-in measures to mitigate volatility of a subject cryptocurrency. The distributed cryptocurrency system may include a number of computer nodes connected via a network. At least some of the nodes may programmatically implement all or portion of a cryptocurrency protocol that programs the nodes to stabilize the value of a subject cryptocurrency. As such, the protocol includes a distributed, decentralized set of programmatic rules for mitigating price volatility of the cryptocurrency. The protocol may include a state determination mechanism to assess whether interventive actions to stabilize a value of the cryptocurrency is triggered. The protocol may electronically expand or contract the supply of the cryptocurrency through use of three different types of electronic tokens that are functionally distinct from one another and that each play a role in expanding or contracting the supply of the cryptocurrency.

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.

A method may include hosting a smart contract. The smart contract may include a reference to an educational offering and one or more conditions, such as one or more student users or educator users staking tokens. The method may include receiving indication that a student user has staked the educational offering by pledging a first amount of tokens and receiving indication that an educator user has staked the educational offering by pledging a second amount of tokens. The method may include determining that the one or more conditions of the smart contract are satisfied. The method may include locking the first amount of tokens of the student user and the second amount of tokens of the educator user and issuing an educational certificate corresponding to the student user.

Embodiments of the present invention provide a system for central authority-permissioned transfer of blockchain tokens. In particular, the a request is received to transfer a set of blockchain tokens that represent an ownership share in a physical asset from a first user to a second user. Information about the first user and second user is compared to a central authority repository that comprises a listing of vetted users permitted to perform transactions with blockchain tokens associated with the physical asset to determine that the first and second users are verified. In response to determining that the first and second users are verified a transaction function is built for the transfer of the set of blockchain tokens from a digital wallet of the first user to a digital wallet of the second user. Finally, the transaction function is published to a blockchain network associated with the set of blockchain tokens.

A method comprises: receiving, via a processor, an audio content of a first file; generating, via the processor, a first acoustic fingerprint from the audio content; comparing, via the processor, the first acoustic fingerprint against a second acoustic fingerprint stored in a record of a database, wherein the record includes an identifier; identifying, via the processor, a match between the first acoustic fingerprint and the second acoustic fingerprint; accessing, via the processor, the identifier responsive to the match; performing, via the processor, an assignment of a digital token from a first user to a second user responsive to the match, wherein the identifier identifies the second user; and alerting, via the processor, the second user of the assignment.

Methods and apparatuses are described for conducting cross-blockchain currency transactions. A server receives, from a client device, a request for a conversion of an amount of a first currency to an amount of a second currency. The amount of the first currency is stored in an electronic wallet associated with a user of the client device. The server determines one or more sequences of currency transactions executable that achieves the conversion from the amount of the first currency to the amount of the second currency, the one or more sequences of currency transactions comprising converting between cryptocurrencies operating on different blockchains. The server identifies one of the one or more sequences of currency transactions associated with an optimal value. The server executes the identified sequence of currency transactions associated with the optimal value.

Embodiments include methods and systems for linking high-value tokens using a low-value token, comprising receiving, from an electronic data server, a first high-value token and a request for a low-value token, the first high-value token being associated with sensitive data associated with a user, and the low-value token being associated with a subset of the sensitive data associated with the user. The methods and systems further comprise providing the low-value token to the electronic data server, and receiving, from a second electronic data server, the low-value token and a request for a second high-value token, the low-value token having been provided to the second electronic data server by the electronic data server. The methods and systems further comprise generating a second high-value token associated with the sensitive data associated with the user, and providing the second high-value token to the second electronic data server.

Embodiments described herein are related to systems and methods for executing randomized event sessions using non-fungible tokens (NFTs). In one aspect, a computer receives token identifiers corresponding to NFTs of a blockchain from one or more client devices. The computer may receive a request to initiate a randomized event session from a session client device. The computer may select a non-fungible token of the NFTs for the randomized event session according to a randomization algorithm configured to randomly identify a token identifier from the token identifiers. The computer may determine, a first award value for the randomized event, based on a value assigned to the non-fungible token, and a second award value based upon a fraction of the first award value. The computer may generate a first award notification indicating the first award value for a first user associated with a first session client device.
