S4FE is a decentralized search network for property, i.e. physical objects, that is based on blockchain technology. Similar to the wide spread search-engines on the Internet, users can add and search entries. The difference of the S4FE search engine is that the network is made up of physical objects. In addition, having blockchain technology as the foundation of the network allows all user transactions and personal data to be cryptographically anonymized.
The concept resembles a global lost-and-found office: the S4FE network’s main goal is to find and identify lost or stolen objects, in order to return them to their rightful owners.
To achieve this, the S4FE network is accessible to everyone and offers users two general functions:
• Objects can be registered and reported to the network in case of loss or theft.
• Objects can be searched, verified and reported as discovered, i.e. if a user discovers an object previously reported as lost or stolen by the rightful owner.
The term Object describes nearly any conceivable form of physical property, that represents a value to its owner. Next to valuables and objects of any kind, this term also includes pets and animals in general.
