Abstract: A cryptographic cold storage apparatus and system. Embodiments of the present disclosure provide for a cold storage apparatus configured to generate a private key, compute an associated PK/PKY and display the latter on a visual display screen. An associated interface apparatus is configured to retrieve the PK/PKH optically and store it in memory. The interface apparatus is configured to produce an associated message and render it at a visual display. The cold storage apparatus may retrieve the message optically, and cryptographically sign the message utilizing one or more public key cryptography methods. The cold storage apparatus produces a graphical output comprising the signed message and renders it at the visual display. The interface apparatus retrieves the signed message and verifies that the cold storage apparatus signed the message, utilizing the public key cryptography methods.

Abstract: A voting system comprises an apparatus and method to provide several advancements to existing voting technology. The voting system combines modern, cryptographically secure blockchain technology with a hard-copy, paper audit trail, and a means for immediate voter verification. The method has the added benefit of eliminating exit polling, if desired by governmental authorities, as real-time tabulations of all votes cast can be calculated using the publicly-available blockchain data.

Abstract: An apparatus comprising a retractable shade constructed of waterproof material that may be spring-loaded and stored inside a housing. The housing may comprise straps or other coupling means to selectively couple the apparatus to a roll bar of an open-top vehicle. For example, the housing may attach via hook-and-loop straps to a center bar of an open-top vehicle, for example a Jeep®. An exterior of the apparatus may incorporate hooks and a pull handle. The hooks may connect into one or more connectors on an upper portion of the open-top vehicle. The pull handle may be utilized to pull the shade from the housing, and engage the hooks to the one or more connectors.
