The Hub of All Things (HAT) is a technology designed to help the Internet exchange and trade personal data. HATs are ‘private data accounts’ that let anyone store their personal data for themselves, so that we don’t have to rely on governments or corporations to store it for us. HATs (and other PDAs) are secure databases that can store one person’s private information. They can be cloud-based or stored locally, and they’re own-able by the individual, so the information inside them is the property of that person. PDAs make it possible for an individual to store and use their information for themselves, and for app developers or companies to build privacy-preserving apps and websites. HATs are an advanced version of these PDAs, called a Private Microservices Data Account or PMDA. These are accessible only via secure APIs, and they have microservices built into them which allow the information inside to be categorised and transacted - with each other or with websites.
