Explain your idea in details:

The LIBER platform would have the function of mediating who is looking to buy books and, through a search geolocation, return the sellers, listing the nearest offers, to contribute to the development of local communities and promoting sustainable and conscious consumption. The innovative approach compared to other solutions currently on the market would be the possibility of finding used books for the purchase or sale of geographically close people and, in the future, the use of Blockchain technology to ensure the security of transactions on the platform.

Expected impact of your idea on sustainable development

Current consumption relationships are unbalanced and require more natural resources than the Earth can offer. The inconsequential consumption points to the emergence of businesses that transform habits and promote the reuse of goods. One of the possible responses to unsustainable consumption habits is the shared economy, which promotes the creation of profitable business models that are concerned with environmental sustainability and social impact. Sharing products and services provides access to a good or service without the need to purchase your property. Collaborative consumption can favor the circulation of wealth, maintaining sustainability in transactions. Examples of initiatives that enable the shared economy are Uber and Airbnb. The LIBER platform's sustainability is in the sharing of products and their collaborative consumption, since the books that the individual possesses will not be discarded and can be of use to another person through sustainable shared economy, avoiding waste and collaborating with the environment.

Plans for implementation and sustainability

Although there are some applications with similar objectives, the sale of used books by geolocation is new. The differential of the project is that Liber has as its central pillar the promotion of sustainable reuse of books and sharing of knowledge among nearby communities. The business model is C2C. In this business model, the commercialization of products and services occurs between two consumers. Through a blockchain network, consumers have entered into smart contracts and any and all transactions will be recorded on that trusted network. With Liber, it will be possible to create a geolocalized book marketplace. Close people will be able to buy the book through the platform and the deal will only be finalized with the confirmation record of both parties. Liber will charge a 1% fee on each sale and purchase transaction. It will be possible to donate books to public or interested libraries through Liber. The construction of an MVP is already underway and the deadline for launching the beta of the application will be made until December 2019.
