What Is The Blockchain?

The blockchain is a word that gets thrown around in the media every day, but what does it mean? Blockchain technology is best known for being the backbone of bitcoin and other cryptocurrency transactions.

However, it has many applications outside of currency. The potential uses are endless! In this blog post, we will take a look at how the blockchain works and some interesting examples of where you can find them today.

What is Blockchain

What is the blockchain and how does it work?

The blockchain is a distributed, decentralized ledger that records all cryptocurrency transactions. As “finished” blocks are appended to it, the blockchain grows and new entries are made.

Every block has the previous block’s hash, a timestamp, and transaction information. Bitcoin nodes use the blockchain to distinguish genuine Bitcoin transactions from attempts to re-spend coins that have

The blockchain is created through the process of mining. Miners are rewarded with cryptocurrency for verifying and committing transactions to the blockchain. Bitcoin miners verify transactions by solving a cryptographic puzzle. Ethereum miners verify transactions using Proof of Work.

The blockchain is maintained by a network of nodes. Bitcoin nodes use the blockchain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.

Ethereum nodes use the blockchain to differentiate legitimate Ethereum transactions from attempts to re-spend coins that have already been spent elsewhere.

How can I use the blockchain today?

The blockchain is being used in several different industries today. Here are some examples:

  • Banks are looking into using the blockchain to streamline and secure their transactions.
  • The music industry is using the blockchain to track copyright ownership and payments.
  • The diamond industry is using the blockchain to track diamond ownership and prevent fraud.
  • The government of Estonia is using the blockchain to store digital identities.
  • The internet of things is using the blockchain to securely transmit data between devices.

There are many other applications for the blockchain that are being developed as we speak! Stay tuned for more examples.

The future of the blockchain, what’s next for this groundbreaking technology

In addition to the applications we have already discussed, there are many more being developed as we speak. The future of the blockchain holds a lot of potentials. Here are some ideas:

Self-sovereign identity management. Governments and other institutions can store digital identities on an individual’s device that is encrypted by their private key with no need for a controlled third party.

Open market for data. Anyone can sell their own anonymous and aggregated transaction data to interested parties without having to go through an intermediary, like Amazon or Google.

Decentralized autonomous organizations (DAOs). A group of people that is governed by code instead of government laws and regulations.

Smart contracts. Contracts are stored on the blockchain and executed automatically when certain conditions are met.

These are just a few examples of what is to come for blockchain technology. The potential uses for this groundbreaking technology are endless! Stay tuned for more updates.


In conclusion, this article has given you a lot of information about the blockchain. It’s been shown to be useful in many different industries including banking, the music industry, and even the diamond trade. The future for the blockchain is looking bright with potential uses such as self-sovereign identity management and open market data that we can’t wait to see unfold!
