Is Polkadot built on rust?
I'm curious about the technological foundation of Polkadot. Could you clarify if Polkadot is indeed constructed on the Rust programming language? Rust is renowned for its memory safety and performance, which seems like a suitable fit for a blockchain project like Polkadot. However, I've also heard about other programming languages being used in blockchain development. Given its significance in the crypto space, I'd appreciate it if you could provide a concise yet informative answer to this question. Your insights would greatly assist me in understanding the technological intricacies behind Polkadot.
