You may know blockchain as the technology behind Bitcoin and several other cryptocurrencies. However, many investors don't have a thorough understanding of blockchain or the best ways to invest in this exciting tech trend.
Here's a brief overview of blockchain technology, followed by some of our favorite blockchain stocks -- and one important principle blockchain investors should keep in mind.

What is blockchain?
Blockchain is a form of ledger technology (also known as distributed ledger technology) that keeps records in a decentralized manner. A bank, for example, can store information (say, payment transactions) on its internal servers, but blockchain technology allows the creation of an unchangeable public ledger that's accessible to all users. Blockchain ledgers are a very secure means of storing data since they cannot be modified retroactively, and they can be used anonymously to protect users' privacy.
It's worth noting that blockchain and cryptocurrency are two different concepts. Blockchain is the underlying technology that powers cryptocurrencies, but it has many other potential applications that have nothing to do with Bitcoin (BTC -2.81%) or other digital currencies.
Think of cryptocurrencies as a car and blockchain as its motor. Sure, you need a motor to power a car, but there are many other potential applications for motors. Just to name a few, blockchain has implications for:
- Digital IDs.
- Rewards and loyalty programs.
- Copyright protection.
- Digital voting.
- Real estate transfers.
- Medical records.
- Wills.

Many publicly traded companies now incorporate blockchain into their operations, offer blockchain-related services to customers, or play a role in the cryptocurrency industry.

Although blockchain technology has been around for a while, it’s still in the early days of real-world implementation. Blockchain has the potential to significantly impact finance, technology, and various other industries in the coming years, though its widespread adoption may take longer to materialize.
