Blockchain storage stores data in a decentralized network that uses idle, hard disc space from people worldwide. The decentralized architecture is a viable alternative to centralized cloud storage and can address many issues that plague centralized systems. The purpose of a blockchain is to allow the recording and distributing of digital information to all participants but never editing. One can use a blockchain to store a variety of data (election votes, product inventories, state identifications, home deeds, and so on); Bitcoin only uses it to create a transparent log of payments.
