Blockchain is a system of recording information that makes it difficult or impossible to change, hack, or cheat the system. It is essentially a digital ledger of transactions duplicated and distributed across the entire network of computer systems.
Somebody can use blockchain technology to create a permanent, transparent public ledger system for compiling data on sales and tracking digital use and payments to content creators, such as wireless users or musicians.
Launching just ten years ago, Blockchain has the potential to become a bedrock in worldwide record-keeping systems. It was created by the unknown persons behind the online cash currency Bitcoin, under the pseudonym of Satoshi Nakamoto.
Solidity is undoubtedly one of the most popular languages used by Blockchain developers. Influenced by C++, Python, and JavaScript, it was designed to target the Ethereum Virtual Machine (EVM). If you are already familiar with these programming languages or you are interested in learning Blockchain, there is a surprising amount of money to be made. Blockchain is considered more of a career than a Side Hustle because Blockchain employees receive an annual salary between $65,000 and $170,000.
By becoming certified in Blockchain technology, you will have an in-depth understanding of Blockchain and how to implement business applications. In addition, certificates for Blockchain are incredibly inexpensive, generally just a few hundred dollars for a comprehensive course. Bring a great return on investment.
