Ah, you've posed an interesting question indeed! So, how old is Polkadot, you ask?
Well, Polkadot isn't exactly an entity with a traditional age. It's a cryptocurrency project, a technological marvel in the blockchain space. But if we're talking about its inception, Polkadot was first conceptualized and announced in 2016 by its creator, Dr. Gavin Wood.
Since then, the project has gone through various stages of development, from whitepapers to testnet launches, and finally, in 2020, Polkadot's mainnet was officially launched. So, in a sense, you could say that Polkadot "came into existence" in 2020.
But of course, its journey doesn't end there. Polkadot is constantly evolving, with new features and upgrades being added over time. So, while it may not have a literal age, it's certainly a young and vibrant project in the world of cryptocurrency and finance.
Does that answer your question? Or perhaps you have more about Polkadot that you'd like to know?
