Published on April 20 in the Ethereum Magicians forum, Vitalik Buterin, the man who seems to have a PhD in thinking several steps ahead, proposed something truly wild: replacing the Ethereum Virtual Machine (EVM) with RISC-V. The goal? Supercharging Ethereum’s scalability while making things easier on everyone’s brains. Oh, and we’ll keep the usual suspects—accounts, storage, and contract calls—just to keep things interesting.
Solidity and Vyper Stick Around (Rust Might Drop By, But No Promises)
Now, don’t panic. Solidity and Vyper, those trusty languages, aren’t going anywhere. They’re going to be tweaked so they can compile directly to RISC-V instructions—because why not make things fancier? Rust could join the party at some point, but Buterin argues that it’s just not as developer-friendly as Solidity. I mean, who can resist those curly braces and semicolons, right?
And here’s the kicker: this whole upgrade won’t break your existing contracts. Everything will continue to work just fine, no matter how you’re coding. So, breathe easy, folks. It’s all smooth sailing—or at least smoother than Ethereum’s transaction fees.

Finally Tackling Ethereum’s Execution Bottleneck (About Time, Right?)
Buterin boldly claims that execution is Ethereum’s last major bottleneck. Everything else is pretty much covered thanks to upgrades like:
- Delayed execution (EIP-7523) – because who doesn’t like a little suspense?
- Block-level access lists (EIP-7694) – making it easier to find what you’re looking for.
- Distributed historical storage (EIP-4444) – because memory is cheap, but not when it’s full of old junk.
The real problem? ZK-EVM proving costs. According to Succinct Labs, block execution eats up almost 50% of prover cycles in ZK rollups. That’s a lot of hungry cycles! While we’re looking to solve this by switching to snazzy new trees and hash functions, execution still reigns supreme as the bottleneck. Go figure.
RISC-V: The Secret Sauce Already Inside ZK-EVMs
Here’s the twist: ZK-EVMs are already using RISC-V under the hood, like a cool secret agent hiding in plain sight. By letting RISC-V take center stage as Ethereum’s virtual machine, Buterin believes we can avoid unnecessary translation headaches. Some tests even suggest a jaw-dropping 100x performance boost in prover efficiency. That’s not a typo—100x! Time to pop open the champagne (or whatever the Ethereum community drinks).
“We should think in decades,” Buterin wisely said. So, while the rest of us are getting distracted by the latest meme coin, Vitalik’s looking ahead to the future of Ethereum. Making this upgrade would be one of Ethereum’s most transformative moves to date—connecting the current developer tools with the zero-knowledge performance we can only dream about. It’s like upgrading from dial-up to fiber optic.
