Abstract: The present disclosure provides computing systems in which respective quorums of computing nodes securely manage respective secrets associated with cryptographic ledgers according to threshold secret sharing schemes. In particular, membership in the quorums can be changed dynamically and unpredictability to improve security of the quorums against adversarial attacks in which adversaries attempt to compromise or gain control of the computing nodes. More specifically, by changing membership in the quorum dynamically and unpredictability, the ability of the adversary to control at any given time a threshold number of the current members of the quorum and gain access to the secret is dramatically reduced.

Abstract: The swing away tailgate barbeque cooking system allows for a cooking apparatus to be mounted on a vehicle or RV. Once at the location, the unit can swing away from the vehicle on a plane up to approximately 180 degrees. The user can then pivot the cooking apparatus into a position that is favorable for cooking. An adjustable leg or legs can be utilized which enable the unit to be much heavier than other swing away units. The adjustable legs make the unit very easy for one person to swing open or swing close. The adjustable legs also allow the unit to be in a level orientation when on uneven ground. The unit can be easily disconnected and rolled away from the carry vehicle. The unit can then be used as a stand-alone grill for home cooking.
