Layer Protocol

The decentralized reputation protocol for the global sharing economy, built on the blockchain.

Even the bigger players in the sharing economy today have no way of knowing a new user's value before their first transaction. Bad actors moving from one service to the next one are a huge expense in the industry, and these costs get passed on to other users through increased fees.

There is currently no way of sharing user reputation data between asset sharing companies. Why would Airbnb even give away their user reputation data to competitors or let's say Uber? While more than 72% of the US population has used at least one sharing economy service, the number for Uber or Airbnb is less than 25%, meaning there is a vast amount of reputation data shared on all sides, and it can drive down operation costs significantly.

Layer Protocol aims to resolve the issue, and will first be adopted by Spin, a stationless e-scooter platform. Live in over 50 markets in the US with over 1M rides in less than a year. Layer Protocol will be Spin's base layer for reputation and rewards. Users will be rewarded when their reputation increases.

3D-Chain is an open-source protocol based on collections of smart contracts which aims to become the key ecosystem for manufacturers, designers and customers. It provides a coordinated decentralized network based on 3D Printing technology and will expand to other manufacturing environments. Within this framework, the benefits of manufacturing and 3D Printing become a global common infrastructure for all. Anyone can access the network, become a stakeholder in its development, add a fabrication technology (e.g. 3D Printer) to 3D-Chain’s ecosystem, add a new design or customize existing one, and receive network payment tokens in exchange. Moreover, demand for personalized design is exponentially growing every year and soon dominate the manufacturing and the economy since personalized items are more appealing to customers than mass-produce items. However, manufacturing new items and personalized them are very expensive and time-consuming. 3D-Chain facilitates the mass customization.
