Top 11 Tech Skills in demand and sites you can learn them for free.

1. Blockchain

Bitcoin is always the first thing that comes to my mind whenever I hear #Blockchain.


Unlike the bitcoin application which is open, public and anonymous making its security and trust questionable – blockchain for business is private, permissioned and running on smart contracts.

It’s a system by which you can track and authenticate a product or a transaction at each stage of its journey. That’s why it’s used across many industries, in finance and many asset transfer businesses.

With blockchain in fashion, a buyer can trace the origin of the leather used in making his jacket and every stage of the transaction until it gets to his designer. But that leather must be made of dragon skin.

Digital forgery and impersonation, data and identity theft, and cyber-bullying are becoming common occurrences as technology advances.

Interesting philosophy!

Many companies and business owners understand that to be relevant in this age is to be tech-savvy and digitally oriented, hence, cybersecurity Conscious.

According to Wikipedia, Computer security, cybersecurity or information technology security is the protection of computer systems and networks from the theft of or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.

We can’t talk about business in this digital age and not talk about the relevance of websites.

Many businesses, organizations, and brands want to have their own unique address that gives them global relevance, accessibility, and market opportunities.
