The term "blockchain" undoubtedly emerged as one of 2017's most buzzworthy concepts. This year witnessed groundbreaking developments that reshaped the digital landscape. Let's explore the pivotal moments that defined the blockchain revolution.
1. ICO: From Frenzy to Regulatory Clampdown

Globally, nations adopted varying approaches:
