Blockchain technology can be used to create a market to promote the sharing or rental of the residual value of an item or services to others. For example, one may have an underused computer that can be rented out to another user who needs a temporary boost in computational capacity. In this case, the blockchain sharing market can be used to complete such a rental arrangement. The platform essentially allows individuals to run a private rental business on virtually anything that is shareable. The blockchain technology-based market is suitable for any device whose usage can be conveniently shared digitally, such as a computer. The market can be used to facilitate the sharing of general services as well. For example, in a European country young people provide nursery services to elders in exchange for credits. The accumulated credits can be used to recieve similar services when a person becomes old. With the blockchain solution, the person will receive digital coins that may be called ServiceCoin for the services being provided to others and can spend the coins later to recieve a service.  This can potentially be a solution to addressing the problem of the high cost of nursery care in the US.
