With the development of new technologies and an increase in the hype, there’s a huge amount of technical terms, acronyms and slang in the crypto and blockchain space. This can be confusing especially when you don’t know what they mean.

With anything that’s new and confusing, it’s always good to get your head around the key terms. Making sure you’re in the loop.

That’s why we’ve put together a list of the key terminology in crypto.
