A physical and digital ‘toolkit’ that equips local communities with the knowledge and resources needed to establish and maintain essential supply chains during periods of global disruption. The OSCT provides instructions on basic manufacturing, food preservation, emergency communication and barter systems, and basic healthcare, all accessible analogically and digitally. All instructions are stored on a secure, localized, and off-grid server. Includes physical tools such as hand-operated mills, water filters, and simple medical equipment.
