The digital world is moving at a breakneck speed. Blockchain technology is one of the newest additions to the ever-growing and ever-expanding digital world. Invented by Satoshi Nakamoto, blockchain technology is an effective digital ledger-based encryption system that offers some of the most secure transaction means. However, as frontier tech gains traction, its use and application are increasingly becoming diverse. The diverse use case and the growing opportunities mean now is a better time than ever to get started with blockchain development. Here’s a list of the best free blockchain development courses to kickstart your blockchain journey.  What is Blockchain Development?  To better understand blockchain development, it is important to get a hold of what blockchain is and how it works. Blockchain is a distributed and decentralized digital ledger system. This ledger system uses a highly encrypted digital footprint that records transactions across multiple computers. The process essentially mimics the way of creating blocks. These blocks are encrypted with immutable technologies. The use of various cryptographic techniques means that you cannot open any block without a specific key. You can’t also modify or alter any blocks as they are immutable meaning it's extremely difficult to rewrite or reprogram them.  Blockchain development takes its shape based on the tech itself. It's an in-demand tech skill that requires in-depth knowledge of the platform, decentralization process, cryptographic techniques as well as blockchain architecture. You don't need to learn all of these aspects of blockchains at the same time. A specialization in a specific discipline, like blockchain architecture can easily kickstart your career as a freelancer or a blockchain developer.  Read more: Best Free Online Scriptwriting Courses in 2024 Top Free Blockchain Development Courses in 2024  The Complete Course on Understanding Blockchain Technology This course is provided for free by Arjun Reddy in Udemy.
