This is a novel idea regarding the use of blockchain technology in allowing people to share or rent unused items via the blockchain by recording an immutable record of all transactions. As users allow sharing and renting of previously discarded or unused items so their reputation increases. This will allow a trustless eco-system to emerge where you are able to use trusted renters for services in the knowledge that they have an impeccable record of past transactions. The energy conscious contingent will also flock to this app as it brings utility to previously "use-less" items creating value.
This would also have a substantial impact upon business development as items can be seamlessly recorded on the blockchain and made available for others allowing a business to increase its coverage via the simple blockchain based app.
The app will bring users together in a trustless environment allwoing profit and value where previously there was none.
Breathtakingly simple in design yet serves a real use and purpose.
