The blockchain technology market could top $2 billion in three years as companies, NGOs and governments understand the potential create customer trust, cut down on counterfeit goods, reduce transaction costs, and reach emerging markets.

While there are a growing number of ways blockchain is being used in banking, retail, and education, it’s still relatively difficult to learn the skills to compete for lucrative new jobs being created.

According to largest global freelancing website Upwork, blockchain is ranked as the hottest technology in its quarterly skills index.  Even with the cooldown of the cryptocurrency markets, the demand for blockchain job skills grew six thousand percent in just the first quarter of this year.

Juha Mikkola, co-founder of Wyncode Academy, a coding school, said some developers are being paid double the going rate for their blockchain experience. "It's not just tech companies that need this talent, it's real-estate, non-profits, and banks," Mikkola said.
