Ethereum

This proposal from @vitalik.eth would be incredible for allowing smart contracts on Ethereum to expand to Rust and other languages: https://ethereum-magicians.org/t/long-term-l1-execution-layer-proposal-replace-the-evm-with-risc-v/23617

Zero knowledge virtual machines like @a16zcrypto’s Jolt, RiscZero, and Succinct’s SP1 use RISC-V, which opens the door for greater Ethereum compatibility with arbitrary Rust code, inheriting the tooling that is already being built around RISC-V

this was a bit too technical for me to follow so i got it simplified. 

Here is what all of this means in ELI5 terms: 

Imagine Ethereum is like a big LEGO castle.

Right now, the people building it use special LEGO blocks called EVM blocks (Ethereum Virtual Machine). These blocks work okay, but they’re kind of slow and tricky to stack in some ways.

Now, some very smart people are saying:
“What if we start using a different kind of LEGO block called RISC-V?”

What would stay the same?
	•	The way you play with the castle doesn’t change.
	•	You still have knights (accounts), treasure chests (storage), and doors to go between rooms (contract calls).
	•	Your favorite tools still work, and the old LEGO blocks (EVM) still fit in.

What would change?
	•	Inside the blocks, how the pieces snap together is simpler and faster.
	•	It could make building and checking the castle much quicker.
	•	Over time, it might help the castle grow bigger without falling apart.

Why bother?
	•	Right now, Ethereum spends a lot of time and energy checking every little thing inside the castle.
	•	Switching to RISC-V would let Ethereum check things faster and use less energy.
	•	Builders can still use the same tools they’re used to (like Solidity), but the engine behind the scenes is better.
