Abstract: A request to perform an action related to a smart contract recorded on a public trust ledger external to the database system may be received via a communication interface at a database system. The request may authenticate a designated database system account. A determination may be made as to whether the designated database system account is authorized to perform the action by accessing definition information for a public trust ledger synthetic party identifying a plurality of database system accounts authorized to perform one or more actions related to the smart contract. The database system may communicate with a token exchange to perform the action by executing the smart contract when it is determined that the designated database system account is authorized to perform the action.

Abstract: In some examples, a computer system receives, via a network and from a software module executable on a mobile device coupled to a card reader, security information that includes first security information associated with the card reader and second security information that is based on content of the software module and/or a software environment of the software module. The computer system determines validity of the first security information associated with the card reader based at least on information previously stored in the card reader and also accessible to the computer system. The computer system also determines the validity of the second security information. Based on determining the first and second security information are valid, the computer system sends, to the mobile device, an indication that the computer system has validated the security information, prompting the software module and the card reader to establish a secure communication session with each other.

The transaction data may include information identifying a transaction amount. The device may determine, after receiving the transaction data, an amount, of the type of cryptocurrency, that satisfies the transaction amount, perform, using the digital signature information, an action to conduct a sale of a portion of the quantity of the type of cryptocurrency based on determining the amount, and cause proceeds from the sale to be transferred to the credit account as payment for the transaction amount.

Abstract: Automated systems and methods for a secure electronic ledger provide a technical solution such that entities referencing the electronic ledger that are associated with a relationship instance can (a) form a consensus that the outcome of the relationship instance is legitimate and (b) determine whether future relationship instances between entities are compliant. An authority entity publishes to the secure electronic ledger data on which digital rules regarding aspects of the relationship instance between a first entity and second entity are based. Entities subscribed to the secure electronic ledger make digitally signed entries in real-time in the secure electronic ledger including data regarding the relationship instance that are visible by all entities associated with the relationship instance.

Abstract: The invention provides a secure method for exchanging entities via a blockchain. The invention incorporates tokenisation techniques, and also techniques for embedding metadata in a redeem script of a blockchain transaction. Embodiment(s) provide a method of: generating a first script, the first script comprising: a first set of metadata associated with a first invitation for the exchange of a first entity by a first user, the first set of metadata comprising an indication of the first entity to be offered for exchange and a first location condition for the exchange, a first user public key (P1A) associated with the first user, wherein the first user public key (P1A) is part of an asymmetric cryptographic pair comprising the first user public key (P1A) and a first user private key (V1A).

Abstract: Methods and systems are described herein for performing cryptographic operations. In particular, the system receives identifiers for blockchain operation requests (e.g., bids) for transferring control of a non-fungible token (NFT) from a first blockchain address to a second blockchain address in exchange for payment (e.g., fungible tokens). The system provides visual indications of the blockchain operation requests to a first user device associated with a first cryptography-based storage application (e.g., an address associated with a cryptographic wallet of a user). The system may receive, from the first user device, a command to approve one of the blockchain operation requests and may determine an on-chain program (e.g., smart contract) for transferring the NFT. The system may submit, to the on-chain program, a request to transfer the NFT to the second blockchain address associated with the approved first blockchain operation request.

Abstract: A method for detecting and tracking tainted cryptographic wallets. The method measures a wallet's propensity to engage in criminal or suspicious activity. Naturally, transacting with a criminal is tantamount either to funding crime or laundering its proceeds, so it is in our collective interest to identify—and then monitor or quarantine—any wallet with criminal association. The method also automatically flags risky withdrawal requests in real-time for further review before committing them to the blockchain. In some embodiments, the exchange can quarantine wallets at a certain AddressScore.

Abstract: A multi-layer cybersecurity system and method for protecting digital wallets holding blockchain-based tokens traded on a financial platform. Specifically, the invention employs random temporal windowing in relation to: (1) reshuffling designated machines running a multi-party computation protocol; and (2) rekeying of private keys held in both hot and cold environments. Furthermore, environmental based signature weighting is applied to the keys. As a result, cold signers can do anything hot signers can but hot signers cannot do what cold signers can such as taking control, recovering control, or reconstitute the holdings of the wallet in real time, if necessary.

Abstract: Methods and systems are presented for providing instant authentication of a product and enhanced user experience with the product via blockchain technologies. A product verification system uses blockchain technologies to track the supply chain process of each instance (e.g., each copy) of a product. Upon receiving a request for authenticating an item, a code provided with the item is scanned. A token corresponding to an instance of a product is determined based on the code. The product verification system traverses a blockchain to access data associated with the token. The item is authenticated based on the data. Additional content provided by the supply chain and/or the manufacturer of the instance of the product may be presented on a user device in response to authenticating the item.
