  • Patent number: 11947522
    Abstract: A method for confirming configuration of a new current genesis block in a blockchain configured to enable pruning before the new current genesis block includes: receiving, by a blockchain node in a blockchain network, a genesis response message from another node in the network, the message including a configuration value and an ordinal value; identifying a plurality of standard blocks in the blockchain added subsequent to an earlier genesis block that includes a number preceding the ordinal value; aggregating smart contract state changes from each of the identified plurality of standard blocks; and validating the configuration value included in the received genesis response message based on the aggregated smart contract state changes. The aggregating of smart contract states can be done by the processor of the blockchain node configuring the new current genesis block, or by another blockchain node.

  • Publication number: 20240059149
    Abstract: Methods and apparatus for detecting hazardous vehicle events and encouraging usage of driving optimized application features to mitigate occurrence of the hazardous vehicle events. The driving optimized application features can address unsafe driving events that are determined to be correlated with certain distracting application features. For example, an application of a computing device can determine that a user is occupying a vehicle and is driving toward a destination. While driving, data available to the application can indicate that an unsafe driving event, such as a hard braking event, has occurred while the user was interacting with another application. Thereafter, and based on this data, the application can render an output characterizing the correlation between the hard braking event and the other application, and/or provide the user with an option to interact with the other application via driving optimized feature(s).

  • Patent number: 11900367
    Abstract: A method for processing offline cryptocurrency transfers includes: receiving, by a receiver of a computing device, a first transfer message, wherein the first transfer message is cryptographically signed using a first private key of a first key pair; validating, by a processor of the computing device, the cryptographic signature of the first transfer message using a first public key of the first key pair; storing, in a memory of the computing device, the validated first transfer message; receiving, by an input device of the computing device, a transfer instruction, the transfer instruction including at least a communication address; and electronically transmitting, by a transmitter of the computing device, the validated first transfer message to an external device based on at least the communication address.
