Blockchain and Cryptocurrency are new concepts to many people, although this is changing every year now as we edge closer to mainstream adoption.
With every new technology comes the inevitable matrix of new terms, abbreviations, acronyms and concepts that at first can seem overly complex, confusing and overwhelming.
Just picture back to when the World Wide Web had been around for some time, but only just becoming a household term.
Back then everyone would have to have learned what the terms browser, URL, email, HTTP, HTML, Domain Name System (DNS), links, pages, Website, Search engine, and much much more.
However, now the above terms and concepts are second nature to many of us throughout the entire world and are used by almost all businesses on the planet.
This is comparable to where Blockchain and Cryptocurrency are now (2021)!
To help breakdown some terminology barriers we have compiled a glossary below to help explain what many of the common crypto terms, phrases or concepts actually mean.
