Defining Blockchain: What Businesses Need to Know

What is Blockchain?

A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as “completed” blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.

Why Use Blockchain?

Blockchain technology is useful for a variety of applications, such as tracking ownership or the provenance of documents, digital assets, physical assets, or voting rights. It can also be used to facilitate peer-to-peer transactions, smart contracts, or other forms of distributed ledgers, which have a wide range of potential uses for business and government.
