Understanding How Blockchain Uses Hashing Technology

Go to http://StudyCoding.org to subscribe to the full list of courses and get source code for projects. How blockchain hashing works shows how a blockchain hashing algorithm is similar to encryption techniques used in password security. The blockchain approach takes hashing to the next step by linking blocks in a series to make transactions in the chain of blocks secure and preventing fraud through a distributed ledger. This takes security away from a central authority and places security in the realm of peer to peer crowdsourced security. Following this is a tutorial in programming a Blockchain example with a Java demo.
