Aspects described herein may relate to a transaction exchange platform using a streaming data platform (SDP) and microservices to process transactions according to review and approval workflows. The transaction exchange platform may receive transactions from origination sources, which may be added to the SDP as transaction objects. As the transactions are processed, the transactions may require access to a resource (e.g., a key value in a database). A microservice processing the transaction may request, from a locking microservice, a lock for the resource. The locking microservice may query a local cache to determine whether a lock exists for the resource. If the local cache determines that no lock exists for resource, the locking mechanism may employ a consensus protocol to obtain a lock for the resource from a plurality of clusters. If consensus is reached, a lock for the resource may be granted to the requesting microservice.

An ecosystem is configured to facilitate digital exchange of digital assets in a digital asset marketplace. The ecosystem includes one or more of a plurality of participant systems selected from a list of participant systems including asset user systems, asset holder systems, and asset mining systems. The ecosystem operates on a computer-executable asset wrapper that is associated with the digital asset and that is configured in the form of a multi-layered structure. The ecosystem also includes a codec that is associated with the asset wrapper and configured as a computer executable file. The codec is executed responsive to a request for an exchange on the marketplace that is associated with the digital asset. The ecosystem further includes a blockchain device to execute a blockchain smart contract for the asset exchange. The blockchain smart contract is executed against a set of right tokens characterizing a specific cryptocurrency value.

A transaction is pre-staged by providing transaction preferences, such as a financial instrument, a transaction type, and a transaction amount, to a user device. The user device captures a visual code at a terminal, such as an ATM. The visual code includes terminal attributes, including a signed hash and call-back URI. The user device authenticates the visual code using the signed hash and requests the transaction through the issuer server. The issuer server creates and sends the card data to the call-back URI. The terminal uses the card data to create a transaction request it routes to through its acquirer server.

Methods, systems, and apparatus for risk mitigation for a cryptoasset custodial system include transmitting an endorsement request for a cryptoasset transaction to a user device configured to cause the user device to prompt a user to endorse the cryptoasset transaction. Multiple data points are collected from mobile devices associated with the user. The data points indicate an identity of the user. A cryptographic endorsement of the cryptoasset transaction is received from the user device. A graphical visualization including a risk metric is generated based on the data points. The risk metric indicates a risk of accepting the cryptographic endorsement from the user device. Generating the graphical visualization includes determining whether the plurality of data points matches expected values.

An asset trading system utilizing a distributed ledger and configured to: when a creation request to create a digital fund token representing at least one share of a fund having a plurality of different assets (i) is received, (ii) is electronically signed with a private key associated with a first addressed account, and (iii) indicates a composition of the at least one share of the fund: place the plurality of different assets represented by the at least one share of the fund into an escrow account; create the digital fund token, wherein the digital fund token indicates the composition of the share of the fund; and record the creation of the digital fund token on a distributed ledger.

A public key infrastructure (PKI) ecosystem includes a first organization computer system having a first processor, a first memory, and a first organization process including instructions that are (i) encoded in the first memory, and (ii) executable by the first processor. The ecosystem further includes a second organization computer system having a second processor and a second memory, a digital ledger, and domain name system security extensions (DNSSEC). When executed, the first instructions cause the first processor to create at least one public/private PKI keypair for a first domain name, in the DNSSEC, register the first domain name and create a certificate authority (CA), register the CA in the blockchain, using the CA, create a certificate for a first entity, register the certificate in the blockchain and/or the DNSSEC, and assert, to the second organization computer system, trust in the first entity based on the registered certificate.

A method and system and computer program product for subscribing to action plans including a processing device for receiving an action plan transaction message having one or more data fields from an analyst node in a blockchain network and generating an action plan transaction in a blockchain including the one or more data fields of the action plan transaction message and a newly generated plan identification. The processing device may transmit an action plan notice to the blockchain network alerting the nodes of the blockchain network of the action plan transaction. The processing device may receive one or more client bids for the action plan transaction, determine a winning client bid of the one or more client bids, generate a winning bid transaction in the blockchain and transmit a winning bid notification to the client node of the winning client bid.

A point-of-sale (POS) system and a data analytic platform provides receipt modification. The POS system has a receipt monitor intercepting receipt data from a POS till. The receipt monitor modifies the receipt data to produce modified receipt data and the receipt monitor transmits the modified receipt data to a receipt printer. A data processing server may receive the receipt from the receipt monitor. The server structures the receipt data, extracts one or more attributes, and may provide modified receipt data to the receipt monitor.

A system includes a processor and a non-transitory computer readable medium coupled to the processor. The non-transitory computer readable medium comprises code that when executed by the processor, causes the processor to receive a money transfer amount indicative of an amount of funds to be transferred to a recipient. The processor generates a key code associated with the money transfer amount that is provided to a user of the system and given to the recipient by the user. The key code is programmed by the processor to enable the recipient to use the key code to redeem the amount of funds associated with the money transfer amount.

To manage property records using a multi-layered hybrid distributed ledger architecture, identification information for a particular property is obtained and transmitted to at least one participant in a public distributed ledger network for a public distributed ledger layer. Ownership information for the same particular property is obtained and transmitted to at least one participant in a federated distributed ledger network for a federated distributed ledger layer. Transaction-related documents for the same particular property are obtained and transmitted to at least one participant in a private distributed ledger network for a private distributed ledger. The distributed ledger layers are different layers of a property distributed ledger each having a separate set of consensus rules for appending distributed ledger data to the respective layer. This allows for the immutable preservation of royalty terms and conditions for a property or asset using the distributed ledger.
