A New research based on data from the employment-oriented networking platform Linkedin shows that blockchain tops the list of most in-demand hard skills. The ranking of the most needed skills was made by looking at those that are in high demand relative to their supply. Demand was measured by identifying the skills listed on the career profiles of people who are getting hired at the highest rates. It divided the skills into two groups. Hard skills include specialized knowledge and technical abilities to handle a specific task, while soft skills are more about behaviour and thinking, personal traits and cognitive skills.
