Is Celestia a blockchain?
Excuse me, I've come across the term "Celestia" quite often in recent discussions on cryptocurrency and blockchain technology. Could you clarify for me if Celestia is indeed a blockchain? If so, what are its unique features that set it apart from other blockchain solutions? I've heard whispers about its scalability and interoperability capabilities, but I'd appreciate a more in-depth explanation. Additionally, is Celestia an open-source project, and what kind of consensus mechanism does it employ? Your insights would be invaluable in helping me better understand this emerging blockchain technology.
