Is PiperNet (Silicon Valley) the same as ETH?

I guess this is a question to aid my understanding of what ETH is/does.

For those who have seen Silicon Valley (the HBO tv show) – is the decentralised network they create towards the end of the show (season 4/5/6) kinda like what ETH is? I was watching it and was like “huh, I’m dumb but, that kinda sounds like ETH”.

For those who have NOT seen Silicon Valley – go watch it, it’s a great show.
