Ethereum’s New Speedy Scheme: Flip the Clock, Save Gas, & Keep Smiling!

by

Key Highlights

  • Ethereum proposes a binary state tree to trim data load, hasten proofs, and economise 10,000+ gas per transaction.
  • A novel RISC‑V virtual machine, poised to run contracts with greater alacrity, shall simplify proofs while remaining utterly compatible with the old EVM.
  • Speedier slots and one‑round finality, promising to cut confirmation from half an hour to a mere eight seconds, shall enhance efficiency.

Like a dear aunt recommending the newest fashion at a ball, Ethereum receives great plans upon execution‑layer upgrades that promise swifter transactions and tighter state verification. The illustrious Vitalik Buterin, even in the realm of the blockchain, is vouching for such sweeping changes.

In a recent post on X, he professed that these reforms seek to render client‑side proofs faster, reduce bandwidth demands, and nurture sophisticated zero‑knowledge applications. Besides elevating efficiency, the updates could reshape Ethereum’s long‑term scalability and those prolific developers’ experience.

Now, execution layer changes. I’ve already talked about account abstraction, multidimensional gas, BALs, and ZK‑EVMs.

I’ve also talked here about a short‑term nice‑nice‑nice upgrade that I believe will be super‑valuable: a vectorised math pre‑compile (basically, do 32‑bit or perhaps…)

Accordingly, Ethereum is gearing up to replace its present hexary Merkle Patricia Tree with a plain binary tree, as outlined in EIP‑7864. Buterin declares that “binary trees can reduce Merkle branches to a quarter of their current length. This renders Helios, PIR and other compatriots a mere four times cheaper by data bandwidth.”

Furthermore, employing swifter hash functions such as BLAKE3 or Poseidon could accelerate proof generation even more. Hence, Ethereum might accommodate ZK applications that interact directly with the principal blockchain state, obviating the need for sundry auxiliary trees. Arranging storage slots into “pages” also lets the network load and edit data more efficiently, potentially saving over ten thousand gas per transaction.

New VM Could Replace EVM for Proofer Efficiency

In addition to refining the state tree, Ethereum may eventually transition from the existing EVM to a RISC‑V-based virtual machine (VM). Vitalik highlights that this new VM will execute contracts faster and simplify proof generation. “A RISC‑V interpreter is only a couple of hundred lines of code; it is what a blockchain VM ought to feel like,” he remarks, hinting at the forthcoming rollout first for pre‑compiles, then full contract deployment, with minimal changes in gas consumption to preserve the EVM’s sanguine compatibility.

Ethereum also plans briefer slot times and swifter finality. Buterin explains that slot times could gradually shrink from 12 seconds down to as little as 2 seconds. A one‑round finality system could cut confirmation time from 16 minutes to a mere eight seconds.

A very important document. Let us walk through this one “goal” at a time. We shall start with fast slots and fast finality.

I anticipate that we shall reduce slot time incrementally, e.g., the “sqrt(2) at a time” formula (12 ➜ 8 ➜ 6 ➜ 4 ➜ 3 ➜ 2, though the latter two…)

Optimised P2P protocols with erasure coding will guarantee that blocks propagate faster, making these smaller slots safe. Moreover, the roadmap promises post‑quantum signatures and STARK‑friendly hashes to safeguard Ethereum against quantum futurity.
