Today, Block chain technology is disrupting almost all markets, changing the way we do our day to day business. Yes, block chain technology is changing our world. The block chain is an incorruptible digital ledger of transactions that can be programmed to record virtually everything of value. Each list of record in a block chain is called block. The invention of the block chain for bitcoin made it the first digital currency to solve the double spending problem without the need of a trusted central authority or central server. The bitcoin design has been the inspiration for other applications. The block chain is a mechanism to bring everyone to the highest degree of accountability. No more missed transactions, human or machine errors, or an exchange that was not done with the consent of the parties involved. The most critical area where block chain helps is to guarantee the validity of a transaction by recording it not only on the main register but a connected distributed system of registers, all of which are connected through a secure validation mechanism.
