Why Rust and Solidity are not efficient for blockchain development?
From Nick Dodson, CEO and co-founder of Fuel

💰Solidity has a lot of shortcomings. Firstly, it was designed in a very fragmented way.

Secondly, It was launched very early to solve a problem, which was "How do we build things on Ethereum?".

But it wasn't really holistically designed for either security or just application design, safe application design in general.

🦀Rust and its toolchain are primarily designed for CPUs, not blockchains. Using a systems language for blockchain doesn't feel good.

The toolchain's optimizations and checks are designed for CPU-specific features like caching, which are useless for blockchain, making the toolchain unsuitable for this purpose.
