Why is cryptocurrency a fundamental necessity in public blockchains?
Could you elaborate on why cryptocurrency holds a pivotal position as a fundamental necessity in the realm of public blockchains? Is it because it serves as the underlying incentive mechanism, enabling participants to contribute resources securely and efficiently? Or perhaps, it's due to its decentralized nature, which ensures transparency and immutability, thus strengthening the integrity of the blockchain? Additionally, does the use of cryptocurrency facilitate secure transactions, enhancing the overall functionality and usability of public blockchains? I'm curious to understand the nuances and intricacies that make cryptocurrency such an indispensable component in this technological landscape.
