What The Heck is Blockchain?

If you’ve been living under a rock terms like blockchain, crypto, and Ethereum probably sound like things that hacker man would use to take down the evil ACME Corp. If you’re one of the millions of people who don’t actually live under rocks you might still have no clue what these terms mean so prepare yourself. You’re about to go to school, blockchain school. It is time to rock the block.

Think of a blockchain as a way to digitally store information with no way to fake or alter the data. Satoshi Nakamoto, the creator of Bitcoin, sought to solve a major problem  that is a constant in every transaction, the middleman. How can we eliminate the need for a trusted third party in transactions of all kinds? This can be accomplished by entrusting the verification of transactions to multiple, random and anonymous connected nodes. Those nodes are the crypto miners. Proponents of the blockchain call it, “a trustworthy system in a trustless world” because by removing the third party middleman safer, faster, and cheaper transactions can occur. Blockchain is basically an immutable public database.

The History of Money & Advent of Crypto

Bitcoin is one example of blockchain tech where a digital currency was mined and granted to people based on the work put in by their computers. Mining programs basically perform complex calculations to verify the other transactions taking place around the globe are legitimate. In exchange for their processing power, they are granted tiny fractions of bitcoins, called satoshis.

Blockchain: Current & Future Potential

If you’re thinking of blockchain from a business perspective, it’s a platform where peers can exchange values using transactions without the need for a central third party. In result, blockchain removes the need to worry about the validity or the security of the transfer. The implications of this could be massive. But let’s talk about the middleman for now. Why is that such a bad thing? Any app you use is relying on a third party backend server, right? If you use an app from Google or an app with a Firebase backend you are entrusting your data, your security, and your information to them. You send it to them and they send it to whoever you’re trying to reach. If their security is breached, your security is breached as well.

Crypto & Blockchain: Technical Overview

Some powerful blockchain examples are cheap, instant, and secure P2P money transfer that is decentralized not through PayPal or another centralized service just peer-to-peer. The blockchain can also be used as a decentralized supercomputer network which employs PCs all over the planet to perform computing tasks. The gaming and movie industry could utilize these supercomputer networks to do 3D rendering for their projects. Peers generate income by renting their computers out to process and perform tasks within the supercomputer network.

Smart contracts play an important part in the future of blockchain technology and cryptocurrencies. With smart contracts, you can exchange property from one user to another without the use of a middleman or intermediary. Smart contracts can be used in almost any type of business or industry. There are use cases for smart contracts in the automotive, financial services, healthcare and retail industries.

What Does It Mean To Be a Blockchain Developer?

This is all possible with blockchain technologies. This is just the beginning. Are you going to join the movement or wait it out?
