Abstract: Systems and methods for providing risk determination in a crypto currency transaction include receiving, through a network via a broadcast by a first payer device, a first crypto currency transaction that includes a first payee public address. A first request for a determination of risk associated with the first crypto currency transaction is then identified in the first crypto currency transaction, with the first request including risk criteria. A first payee involved in the first crypto currency transaction is then identified using the first payee public address, and first payee risk information is accessed via at least one external risk information database based on the identification of the first payee. If it is determined that the first payee risk information satisfies the at least one risk criteria in the first request, the first crypto currency transaction is provided for addition to a block in a crypto currency public ledger.

Abstract: A method of selectively locking a cryptographic digital asset includes instructing or requesting the creation or minting of a plurality of cryptographic tokens via a first common digital contract registered to a distributed ledger. Each cryptographic token is a digital asset that includes at least one attribute that is operative to evolve or change through a plurality of evolutionary stages. The plurality of cryptographic tokens are then instructed to be transferred to a plurality of token holders. The method further includes receiving a request from a token holder to selectively lock their digital asset at one of the plurality of evolutionary stages; and instructing or requesting the transfer of a second cryptographic token to the token holder, the second cryptographic token having at least one attribute that is at least partially derived from the evolutionary stage of the digital asset at the time of the request.

The processor may be configured to receive a first data set, wherein the first data set is associated with a second NDEF read. The processor may be configured to extract metadata from the first data set. The processor may be configured to perform, after the first factor authentication, a second factor authentication based on the metadata.

The processor may be configured to transmit the message that instructs the processor to effectuate one or more actions.

Abstract: In an example embodiment, information about one or more failed payment attempts via an electronic payment processing system is obtained. One or more features are extracted from the information. Then, for each of a plurality of potential candidate retry time points, the one or more features and the potential candidate retry time point are fed into a dunning model, the dunning model trained via a machine-learning algorithm to produce a dunning score indicative of a likelihood that a retry attempt at an input retry time point will result in a successful payment processing. The dunning scores for the plurality of potential candidate retry time points are used to select a desired retry time point. Then the electronic payment processing system is caused to attempt to reprocess a payment associated with one of the failed payment attempts at a time matching the desired retry time point.

Abstract: A method for securing a split private key (such as used with a cryptocurrency or other non-custodial electronic wallet) amongst a password, biometrics, and a social service. The process may use a sharding scheme such as Shamir's Secret Sharing to ensure that multiple key shards must be obtained before the entire private key can be obtained. The user may select the number of shards required to retrieve the private key thereby controlling the security of the account. An additional shard may be held on an encrypted server and allows for account recovery even while maintaining non-custodial ownership of the wallet.

Abstract: Systems and methods are provided for leveraging blockchain technology in a swarm learning context, where nodes of a blockchain network that contribute data to training a machine learning model using their own local data can be rewarded. In order to conduct such data monetization in a fair and accurate manner, the systems and methods rely on various phases in which Merkle trees are used and corresponding Merkle roots are registered in a blockchain ledger. Moreover, any claims for a reward are challenged by peer nodes before the reward is distributed.

Abstract: The invention proposes a network transactional system, comprising a set of token nodes (TN), a set of user nodes (UN) and a set of provider nodes (PN), the nodes being capable of executing an executable contract for a user node to obtain token account units (Voucher Tokens) by reserving (R) reserve account units according to a value of the token units which itself varies according to the reserve, the number of token units in circulation and the reserve ratio (RR). A provider node is associated with each token node and the token is representative of a product or asset (good, service, right or other benefit) of the provider, or a group of such products or assets.

Abstract: Aspects described herein may relate to methods, systems, and apparatuses for applying machine learning techniques as part of registering, for a user, a payment card with at least one account of a merchant. The machine learning technique may be an unsupervised learning classifier that is configured to determine classifications of merchant groups and/or user groups. Based on a classification, the user may be able to select which merchants to register the payment card. Based on the selection, the payment card may be registered with the user's account at the selected merchants. Further, the registration may be performed based on virtual payment card information configured for use with the merchant. The virtual payment card information may be configured to initiate transactions only with the merchant.

Abstract: A novel architecture for a infinitely scalable cryptocurrency system is disclosed in the form of multilevel tree hierarchy of blockchains, where the hash for each block in each blockchain is not only passed to the next block in that blockchain, but is also passed to at least one other blockchain on another level to be included in its own hashes, such that no change can be made in any of the blockchains in the hierarchy without recomputing them all. To facilitate maintaining these multiple levels of blockchains, a novel proof of connectivity lottery method is disclosed whereby all active devices connected online associated with a particular blockchain exchange messages where a hash that cannot be controlled by any particular device determines the winner of the lottery.
