Blockchain. It was in every headline for a few years; it was the subject your really intense cousin would never shut up about at Christmas; and in 2018, it crashed hard. Now, blockchain technology is making a more stable, more rational comeback in industries from health care to farming — and financial services are still leading the way.
The basic structure of blockchain consists of individual records, all connected using cryptography. This infrastructure allows blockchain networks to be distributed — not necessarily run by a central authority — while maintaining security, because nobody can change just one block in the chain. It’s an appealing model for many sectors, promising transparency and trust as it helps make value exchange possible.
