Abstract: Methods and systems are presented for providing a framework for facilitating multi-party computation within a sharding environment. After a blockchain is divided into multiple shard chains, a multi-party computation system obtains attributes associated with a first shard chain. The attributes may represent characteristics of the first shard chain, characteristics of transactions recorded in the first shard chain, and characteristics of the computer nodes configured to manage the first shard chain. Based on the attributes, the multi-party computation system determines a multi-party computation scheme that specifies a minimum threshold number of nodes required to participate in a transaction validation process and at least one required node required to participate in the transaction validation process for the first shard chain.

Abstract: A system, including: a non-transitory memory; and one or more hardware processors coupled to the non-transitory memory and configured to read instructions from the non-transitory memory to cause the system to perform operations including: detecting a first automobile; determining that the first automobile is a self-driving automobile; and in response to determining that the first automobile is a self-driving automobile, causing a second automobile to emulate a motion of the first automobile.

Abstract: There are provided systems and methods for initiating a device security setting on detection of conditions indicating a fraudulent capture of a machine-readable code. A service provider, such as an electronic transaction processor for digital transactions, may provide in-person or device-to-device data transfers through machine-readable codes, such as to effectuate a payment from one mobile device to another. However, unauthorized devices may be in close enough proximity to also capture the code and impermissibly use the code. Thus, device security settings are used to detect whether fraud may occur in certain settings and implement an operation to hide a valid code. This may include operations to obtain information for the unauthorized device, make the code dynamic, or mask the code in a display. Once a nearby valid scanner is detected, such as through emitted light or sound, the valid code may be displayed.

Abstract: Fluid collection pouches and surgical drapes for use in surgical procedures are described. The described fluid collection pouches can be configured in some cases to define a region of greater depth of the pouch beneath a patient's limb extending through the pouch on the lateral side of the limb than on the medial side. In some cases, the fluid collection pouches can be configured to define an upper surface with a region that extends at a greater height above a patient's limb extending through the pouch on the lateral side of the limb than on the medial side.
