If you’ve spent any time on the internet for the last few years, there is a good chance that you have heard about Blockchain technology, especially in circles that also talk about cryptocurrency. If you’ve been wondering what it is and how it can help you, keep reading.

What is Blockchain?

Blockchain is a way of recording and tracking transactions and assets that makes them less vulnerable to fraud and cyberattacks. It is essentially a public ledger that saves each transaction as a block linked to transactions that come before and after it, creating a blockchain.

The blockchain is public, and all participants can see all of the transactions. No one can delete or alter a recorded transaction, even if the information is wrong, and the blockchain can contain rules for transactions to help prevent inaccuracies.

Benefits of Blockchain

Many businesses waste time and resources keeping duplicate records and validating the data in those records. Blockchain eliminates duplicate records, and transaction rules can help ensure the data is correct. It can also help build trust between users because the data cannot be changed or deleted and is public to everyone.

Types of Blockchain Networks

Public Blockchain Networks

Public blockchain networks are available for anyone to use, but there is little privacy and lower security.

Private Blockchain Networks

Private blockchain networks are operated by an entity and work like public blockchains but with increased privacy and security.

Permissioned Blockchain Networks

Permissioned blockchain networks are private blockchains that grant users access on a permission basis. Permissioned blockchains can have many more users than you usually find on a private blockchain but still maintain a higher level of privacy and security thanks to the trusted users.

Consortium Blockchains

A consortium blockchain is one that multiple users have a hand in maintaining. Banks and healthcare providers might use a consortium blockchain because of the many different facilities within the larger organization that need access.

What Can an Individual Do with Blockchain?
