Abstract: A second blockchain system receives a first consensus message from a first blockchain system, the first blockchain system includes first nodes that provide services to at least a first account, and the second blockchain system includes second nodes that provide services to at least a second account. The first consensus message indicates a first plurality of the first nodes reaches a consensus for transferring a resource from the first account to the second account. The second blockchain system transfers the resource in the task to the second account. The transferring includes that a node in the second nodes adds the resource to the second account and generates a fourth block that records a completion of a transfer event. A second consensus message is transmitted from the second blockchain system to the first blockchain system in response to a second plurality of the second nodes completing the transfer event.

Abstract: A crypto ETP is administered by a portfolio modeling computer/(PMC), a fund administration computer/(FAC), an order taking platform computer/(OTP), a custodian computer/(CC), and a paying agent settlement computer/(PASC). The PMC defines the ETP and captures data for a cryptocurrency index. The CC tracks Underlying Assets held by the ETP, and sends the data to the FAC, which calculates the NAV of the Underlying Assets to generate a Portfolio Composite File/(PCF) sent to the OTP. The OTP receives and validates/confirms with the CC, orders for creations and redemptions of the ETP from Authorized Parties/(APs), in exchange for the Underlying Assets and/or cryptocurrency. The PASC provides settlement on the Exchange in cryptocurrency by: receiving confirmation from the CC of transfer of underlyings, ETPs or cryptocurrency from the APs to a blockchain wallet associated with the PCM; and issuing units of the ETPs, underlyings or cryptocurrency to the APs.

Abstract: A method for processing cryptographic currency transactions through user-based blockchain ledgers includes: receiving, by blockchain node in a blockchain network, a new cryptographic currency transaction from a first computing device including unspent transaction outputs, a sender public key, receiver public key, destination address, and cryptographic currency amount; identifying, by the blockchain node, a sending blockchain associated with the sender public key including the unspent transaction outputs; validating, by the blockchain node, the sending blockchain by generating a hash value using the sending blockchain and comparing the generated hash value to a historic sender hash value associated with the sender public key; generating, by the blockchain node, a new sender hash value by hashing a combination of the sending blockchain and the new cryptographic currency transaction; and transmitting, by the blockchain node, the generated new sender hash value to a plurality of additional nodes in the blockchain

Abstract: A blockchain-based system and method for enforcing a smart contract on a network comprising one or more cryptographically-signed blocks. The systems and method permit an original lender or regulatory body to manage risk by tracing a security loan from end-to-end. The system and method also dynamically tracks the value of the loan collateral and if the collateral falls below a predetermined a minimum collateral value threshold within a range of tolerance the system automatically transmits recall and stop trade orders to the relevant parties. In addition, as the chain of transactions grow, the system and method continue to add to an immutable easily verifiable blockchain which facilitates verification and regulatory compliance.

Abstract: A digital content distribution system uses a Digital Rights Management Controller that performs a set of arbitrary tests against the transfer request from one user to another such as user A to user B. Assuming these tests are successful, the DRM sends an encryption key to transferring user A. This encryption key E is taken from a table of encryption key/hash pairs which have been provided to the DRM Controller by an external authority such as the content rights holder. User A encrypts the content using they key provided by the DRM controller and then optionally calculates a hash over the encrypted form of the content E(X) and returns this value to the DRM Controller. On checking the returned hash against the hash from the table the DRM controller knows that user A does indeed have the digital content X in good condition. The DRM Controller then instructs both users A and B that the transfer may proceed. The encrypted form of the content E(X) is transferred from A to B.

Abstract: Securely sharing proof of knowledge of information without revealing the information, for example to allow an institution to prove it has knowledge regarding an alert. Code or software may be generated (at a first computer system) which takes as input one or more details regarding an entity and returns a value based on a match to one or more actual details regarding the entity. A name may be generated for the code based on information describing the entity, and the code may be published to a blockchain, along with at least one key corresponding to the code. For each name an entry may be creating in an index, converting the name to a blockchain address. A proof based on the code may be generated at a second computer system, which, if verified, results in the first institution and the second institution sharing information regarding the entity.

Abstract: This disclosure enables various computing technologies for smart contracts to be audited in ways that improve on conventional auditing approaches mentioned above. These technologies improve functioning of computers by enabling large language models to review bytecodes executable on distributed ledgers to determine whether those bytecodes enable smart contracts on those distributed ledgers and then acting accordingly.

Abstract: A system for licensing an application or feature for use on a wireless mobile device is disclosed. The wireless device is provided to a user with a licensable application or feature, but the application or feature has not been fully authorized for use. When the wireless device receives a request to use the application or feature, the device operates the requested application or feature, and generates an irrevocable license request. The license request is transmitted to a license server at a time convenient for the device. The license server generates a license certificate to the application or feature, and transmits the license certificate to the wireless mobile device. The device receives the license certificate, which is stored in local memory. The application or feature is now fully licensed for future operation on the wireless mobile device. The license server operates accounting processes to generate license reports and license accounting information.

Abstract: A method of performing a contactless transaction between a payment device and a terminal is described. The method comprises establishing a data connection between the payment device and the terminal and then establishing if the payment device and the terminal both support an enhanced security architecture. If they do not, they will then perform the contactless transaction according to a basic transaction flow using a first cryptographic system. If they do, they will perform the contactless transaction according to an enhanced transaction flow using a second cryptographic system. The first cryptographic system and the second cryptographic system comprise different asymmetric cryptographic systems. Suitable payment devices and terminals, and methods at the payment devices and terminals, are described.

Abstract: Systems and methods are disclosed for establishing information on a state of a machine-executable contract in the context of unspent transactions (UTXOs), blockchain and deterministic finite automaton implementation of contracts, and determination of states within those. Stages of a method include determining information of interest and codes or tags identifying that information, constructing metadata associated with those codes or tags, and combining the metadata with a public key for an agent associated with the information. ScriptPubKey values of each script are used to provide keys for constructing a database and mapping the keys from the scriptPubKey values, linked to the information. A derivation of script hash addresses from the scriptPubKey values is used to populate a digital wallet. A search and match algorithm is used to find UTXOs with matching script hash addresses on a blockchain. The database is populated with UTXOs that match the script hash addresses and keys to complete the combinations.

Abstract: Systems and methods for establishing a living arrangement between a staker of cryptocurrency and an owner of a real property are described. Distributed ledger technology may be leveraged to facilitate arrangements between a staker (e.g., a cryptocurrency staker) and an owner (e.g., a real property owner). The staker may receive aspects (e.g., staying rights, etc.) of a real property by locking cryptocurrency to a smart contract, where a portion or all of the residuals from decentralized financial activities may be earmarked for the owner. In some cases, maturity of the arrangement may be residual dependent (e.g., where the arrangement terminates once the sum of the residues to the owner reaches a threshold). At the maturity of an arrangement, the staked amount may be unlocked and available for the staker, and the owner's interest in the title (or deed) is transferred and claimable to the staker.
