Abstract: In variants, a node resource management system, determine which of a set of managed blockchain nodes are participants in a blockchain event for the respective node's blockchain; and preferentially allocating computing resources, shared by the set of managed blockchain nodes, to the participating managed nodes.

Abstract: In variants, the system can include a set of blockchain modules and a set of interaction mechanism handlers configured to convert a unified set of system commands into blockchain-specific commands for each of a set of blockchains and/or blockchain nodes.

Abstract: A liner bridge for a lined pipeline has bores extending through a tubular wall and terminals fitted in the bores, each terminal being exposed to an inward side of the wall for conducting electricity to an electrofusion element. A sealing interface between each terminal and its surrounding bore has one or more projecting formations of the terminal and at least one complementary formation of the bore engaged with the or each of the projecting formations. The interface can also include a sealing mass in the bore.

Abstract: In variants, systems and methods for managing a set of blockchain resources can include, for each of a set of managed blockchain resources, each including a blockchain node hosted on a machine: determining a machine state of the machine; determining a node state of the node; and managing the blockchain resource based on the machine state and the node state, wherein the machine is not restarted when the machine is offline but the node is online. In examples, the machine state and node state can be determined using different communication channels.

Abstract: One variation of a method for changing a state of a wearable device includes: in response to detected motion of the wearable device, transitioning from a low-power mode into a test mode; in the test mode, detecting a proximity of a surface to the wearable device, detecting a temperature of the surface, and based on a temperature of the surface correlated to a human skin temperature, transitioning from the test mode into an active mode; and, in the active mode sampling a heart rate sensor arranged within the wearable device and wirelessly broadcasting a value corresponding to an output of the heart rate sensor.

Abstract: One variation of a method for monitoring sleep of a user includes: assigning a collective wakefulness model—generated from sleep data collected from a set of other users—to the user for a first time period; storing a first set of vitals data collected by a wearable device worn by the user during first time period; extrapolating, from the collective wakefulness model, a first waking time of the user for a first sleep event during first time period based on data in the first set of vitals data; queuing the first waking time for transmission to a mobile computing device linked to the account for presentation to a guardian of the user; in response to expiration of the first time period, generating an individual wakefulness model specific to the user based on the first set of vitals data collected during the first time period.
