WHAT IS BLOCKCHAIN ?


Blockchain technology might be one of the most-hyped innovations of the 21st century. Developed to support bitcoin, blockchains now power thousands of cryptocurrencies, and developers are working on integrating the technology into businesses, including medicine, art and finance.

A blockchain is a public digital ledger of transactions maintained by a network of computers in a way that makes it difficult to hack or alter. The technology offers a secure way for individuals to deal directly with each other, without an intermediary like a government, bank or other third party.

The growing list of records, called blocks, is linked together using cryptography. Each transaction is independently verified by peer-to-peer computer networks, time-stamped and added to a growing chain of data. Once recorded, the data cannot be altered.

While popularized with the growing use of bitcoin, ethereum and other cryptocurrencies, blockchain technology has promising applications for legal contracts, property sales, medical records and any other industry that needs to authorize and record a series of actions or transactions.
