Could you please elaborate on the concept of a 
cryptocurrency blockchain? In layman's terms, what does it entail? Is it simply a record of transactions or does it have more sophisticated functions? How does it ensure the security and transparency of cryptocurrency transactions? Additionally, how does the blockchain technology facilitate the decentralized nature of cryptocurrencies? I'm curious to understand the underlying principles and workings of this crucial component in the cryptocurrency ecosystem.
