Each node has its very own duplicate of the chain that receives current as fresh blocks are confirmed and additional. Which means when you needed to, you could track a bitcoin where ever it goes.
The global achieve and tight stability of blockchain networks established the stage for direct details storage. Equally as a knowledge block can maintain total records of a posh transaction, it could also have a small bit of the information in a sizable file. When that file needs to be available within the fall of a hat and around the world without the need of sacrificing knowledge safety, it makes lots of sense to distribute it throughout a blockchain as an alternative to serving up the entire file from a central server.
