What is Blockchain?

Blockchain is literally just a chain of blocks. When we say the words “block” and “chain” in this context, we are actually talking about digital information (the “block”) stored in a public database (the “chain”). 

"Blocks” on the blockchain are made up of digital pieces of information.

Specifically, they have three parts:

  1. Blocks store information about transactions, say the date, time, and dollar amount of your most recent purchase from Amazon. (NOTE: This Amazon example is for illustrative purchases; Amazon retail does not work on a blockchain principle)

  2. Blocks store information about who is participating in transactions. A block for your splurge purchase from Amazon would record your name along with, Inc. Instead of using your actual name, your purchase is recorded without any identifying information using a unique “digital signature,” sort of like a username.

  3. Blocks store information that distinguishes them from other blocks. Much like you and I have names to distinguish us from one another, each block stores a unique code called a “hash” that allows us to tell it apart from every other block. Let’s say you made your splurge purchase on Amazon, but while it’s in transit, you decide you just can’t resist and need a second one. Even though the details of your new transaction would look nearly identical to your earlier purchase, we can still tell the blocks apart because of their unique codes.Student at computer

Why Blockchain Technology?

Blockchain development is the hottest IT job skill today. The job of developing blockchain distributed ledgers for businesses was recently ranked first among the top 20 fastest-growing job skills – and postings for workers with those skills grew more than 200 percent last year.  - Computer World, June 5, 2018

A number of industries from insurance, banking, shipping, health care, retail and e-finance have begun adopting blockchain technology to secure transactions and smart contracts.

New Program at MCC
