What is Blockchain Technology? Is It Secure and Viable in 2022 and Beyond?

At its most basic level, a blockchain is a type of shared database that differs from a typical database. It stores information; blockchains store data in blocks linked together via cryptography. 

As new data comes in, it goes into a new block. Once the block fills up with data, it gets chained onto the previous block, which makes the data chained together in chronological order. 

You can store different types of information on a blockchain, but the most common use has been as a ledger for transactions. For example, when you purchase using Bitcoin, the transaction is recorded on the Bitcoin blockchain. 

So, what are some potential applications of blockchain technology? Of course, the most obvious application of blockchain technology is in the financial sector. 

Many banks and financial institutions are already experimenting with blockchain-based transactions and exploring ways to use this technology to make their services more efficient and secure. 


Bitcoin is the first and most well-known blockchain innovation. It was a proof-of-concept digital currency that launched in 2009. 

Although its price has fluctuated widely, bitcoin’s market capitalization now hovers between $10 billion and $20 billion. With the help of Acorns and other micro-investing alternatives, millions of people use blockchain technology for transactions, including remittances. 

The potential implications of blockchain technology are vast and could revolutionize the way we interact with the digital world.
