Vitalik Buterin’s Bold Ethereum Overhaul Plan: Fixing Bottlenecks or Just Throwing Darts?

by

Ah, Vitalik Buterin, the ever-enthusiastic maestro of Ethereum, has once again waved his magic wand and conjured up another proposal that, according to him, will radically transform the Ethereum network. Not content with merely “tinkering,” Buterin has decided that Ethereum’s architecture-specifically its state tree and virtual machine (VM)-are like the troublesome twins of a dysfunctional family, always tripping over one another and preventing real progress.

In a post so long it might be mistaken for a Dostoevsky novel, Buterin expounds on his epiphany: the state tree and VM are the biggest bottlenecks choking Ethereum’s proof efficiency, claiming they account for over 80% of the inefficiency. His solution? Deep, all-encompassing changes to eliminate these “mandatory” obstacles. Surely, Ethereum can’t grow without this monumental shift, right?

The Ethereum Overhaul: Vitalik’s Version of “Spring Cleaning”

Let’s dive into the details, shall we? Vitalik references EIP-7864, an idea from Guillaume Ballet and colleagues, which suggests ditching Ethereum’s clunky, hexary Keccak-based Merkle Patricia Tree in favor of a sleek binary tree using a better hash function. This new setup would trim down the Merkle branches by four times-because, you know, who doesn’t want their branches shorter?-cutting bandwidth and reducing client-side verification costs. A mere 4x reduction in data costs for tools like Helios, you say? Sounds revolutionary!

But wait, there’s more! Vitalik dreams of BLAKE3, a hash function that’s supposedly three times more efficient than Keccak. If that wasn’t ambitious enough, he even dangles the prospect of Poseidon, which could offer improvements up to 100 times greater-though it’s not all sunshine and rainbows, as further security work would be necessary. So, no pressure, right?

The proposed binary design also suggests grouping storage slots into 64-256 “pages,” which would allow for more efficient loading and editing. Forget about wasting gas-this could save more than 10,000 gas per transaction for applications that access early storage slots. Who knew that Ethereum’s future could be so… pragmatic?

And for all you zero-knowledge enthusiasts, this new state tree is designed to be “prover-friendly,” meaning zero-knowledge applications could integrate directly with Ethereum’s state instead of building their own clunky trees. It’s almost as if Vitalik is on a personal quest to make Ethereum more… user-friendly. Who would’ve thought?

The RISC-V VM: Vitalik’s Long-Term Dream, or Just Another Pipe Dream?

Not satisfied with simply revolutionizing the state tree, Buterin proposes eventually swapping out Ethereum’s current VM for a RISC-V-based one. He calls it a “longer-term” solution, which translates to “we’ll get there eventually, but don’t hold your breath.” According to him, RISC-V would be more efficient, simpler, and just better all around. And since many provers are already written in RISC-V, implementing it would only require a few hundred lines of code. Yes, just a few hundred lines, because anything less than that would be an insult to the Ethereum community, right?

His roadmap for this transition is as grand as one would expect: first, use the new VM for precompiles, then let developers deploy contracts in the new system, and finally, phase out the old Ethereum Virtual Machine (EVM). The kicker? All of this comes with full backward compatibility-except, of course, for gas cost changes. But hey, who needs consistency when you can scale to the moon?

In conclusion, Buterin’s latest proposal feels like a shot in the dark-perhaps a better one than his previous attempts, but still speculative. It’s as if he’s saying, “Let’s fix Ethereum with one giant leap for mankind,” while hoping no one notices the minor hurdles along the way. Oh, and by the way, this all comes right after his quantum resistance roadmap. Because why settle for fixing today’s problems when you can predict tomorrow’s too?
