Learn how to build a blockchain from scratch with Go Programming Language (Golang). With the emergence of Facebook's cryptocurrency, Libra, companies like Amazon, Microsoft, and IBM are also joining the virtual currencies trend. Blockchain development technology is anticipated to play a crucial role with IoT, medical, and even the real estate fields.

Why this course?

1. Learn by doing and not just listening!

This course provides a hands-on approach to learning about Blockchain concepts, intuition, and implementation. In this course, we'll be utilizing Blockchain technology and Go to develop a money transfer system.

2. Easy to understand

Confused by Blockchain? With much of Blockchain technology explained in complicated technical documents, many people may think of Blockchain as something that's confusing. But Blockchain and the technology underpinning the cryptocurrency, has the potential to revolutionize the platform for future network distribution systems.

3. Blockchain is the future

With a blockchain network, cross-border money transfers and many other transactions involving digital assets can all be made possible by just about anyone with access to the internet. But have you ever thought about how Blockchain can provide a solution for many of the challenges of registration related to land ownership and real estate? Implementation of a blockchain-based registry can enable the ownership documents to be recorded and assigned to an owner's user account. With Blockchain, every transaction is traceable, timestamped, and indisputable. Used in this way, blockchain can provide a highly secure record of ownership that can't be manipulated or lost. The possibilities of the uses of blockchain are endless - from voting systems to issuance of IDs such as passports - all can be made possible with blockchain technology.

About the Author: Udemy

Udemy thumbnail

Udemy is the largest open marketplace for online courses on the internet. Founded in 2010 by Eren Bali, Oktay Caglar, and Gagan Biyani and headquartered in San Francisco, the company went public on the Nasdaq in 2021 under the ticker UDMY. The platform hosts well over two hundred thousand courses across software development, IT and cloud, data science, design, business, marketing, and creative skills, taught by tens of thousands of independent instructors. Roughly seventy million learners use it worldwide, and the corporate arm — Udemy Business — supplies a curated subset of that catalog to enterprise customers.

Because Udemy is a marketplace rather than a single editorial publisher, the catalog is uneven by design. The strongest material lives in the long-form, project-based courses authored by working engineers — full-stack JavaScript, React, Node.js, Python data science, AWS, Docker and Kubernetes, mobile development with Flutter and React Native, and cloud certification preparation. The CourseFlix listing under this source is the slice of that catalog that has been mirrored here for offline-friendly viewing, organized by topic and updated as new releases land. Pricing on Udemy itself swings dramatically with the site's near-permanent sales, which is why the platform is best treated as a deep reference catalog: pick instructors with strong reviews and a track record of updating their material rather than buying on the headline price alone.
