The Highway Analogy: Vitalik Buterin’s Plan to Scale Ethereum 1000x

In current commentary on the way forward for Ethereum, Vitalik Buterin mentioned a substantial pivot – the community ought to prioritize rising its bandwidth (capability to deal with knowledge) over decreasing latency (pace of transaction processing).

His core argument rests on the distinction between what’s troublesome and what’s bodily unattainable. Reducing latency, which basically means the time it takes for a transaction to be confirmed, is basically constrained by the pace of sunshine, amongst different issues:

“We are basically constrained by the pace of sunshine, and on high of that we’re additionally constrained by […] want to help nodes in rural environments, worldwide, and in residence or industrial environments outdoors of information facilities, want to help censorship-resistance and anonymity for nodes, and many others… [Quote shortened for editorial purposes].”

Although it sounds sophisticated, there’s a comparatively easy means to visualize this idea.

The Highway Analogy: Bandwidth vs. Latency

To greatest perceive what Buterin speaks about, image Ethereum as a freeway. The drawback is traffic-related – you need to transport extra individuals.

You solely actually have two choices:

  1. Reduce the latency (pace) of transportation by making each automotive drive loads faster.
  2. Increase the bandwidth (capability) of the freeway by constructing extra lanes.

Buterin argues that Ethereum ought to go together with the second choice as a result of making an attempt to make the vehicles journey faster is harmful and basically constrained.

This additionally ties to one other put up he wrote 5 years in the past titled The Limits to Blockchain Scalability. In it, Ethereum’s co-founder discussed a tweet by Elon Musk:

Vitalik outlined how difficult that is with out sacrificing safety and decentralization. In essence, he argued that common individuals ought to give you the option to run nodes on their customary tools (resembling laptops), that means that the blockchain is of course constrained by the capabilities of this tools. The different is for nodes to be run by way of knowledge facilities, which dangers centralization:

The elites of your blockchain neighborhood, together with swimming pools, block explorers and hosted nodes, are in all probability fairly well-coordinated; fairly seemingly they’re all in the identical Telegram channels and WeDiscussion groups. If they actually need to set up a sudden change to the protocol guidelines to additional their very own pursuits, then they in all probability can.

That stated, he additionally stated that latency can, certainly, be diminished with present applied sciences, with out making tradeoffs. These embrace:

  • P2P enhancements (esp erasure coding), (which) can lower message propagation occasions with out requiring particular person nodes to have decrease bandwidth.
  • An obtainable chain with a smaller node depend per slot (eg. 512 as an alternative of 30,000), which may take away the necessity for an aggregation step, permitting the complete sizzling path to occur in a single subnet.

According to Buterin, this alone can scale Ethereum by three to six occasions and is “very a lot within the realm of risk.”

The World Heartbeat

And but, this explicit technical divergence defines Ethereum’s final goal – to be the World’s Heartbeat as an alternative of the World’s Video Game Server. 

He argues that with present applied sciences resembling PeerDAS and ZKPs, the means to scale exist and Ethereum will be scaled 1000’s of occasions, no less than in contrast to the present established order. He additionally outlined that the numbers grow to be much more favorable than earlier than, and that there isn’t a constraint that stops “combining excessive scale with decentralization.”

Following my earlier analogy, this merely implies that there’s nothing stopping the group from constructing a freeway with as many lanes (presumably 1000’s) as wanted.

However, this additionally implies that there’ll come a time when purposes would possibly require speeds larger than the heartbeat (e.g. Ethereum). In that case, Vitalik says that these purposes ought to have off-chain elements. This additionally implies that layer two scaling solutions will proceed to have a job sooner or later, even when Ethereum is scaled tremendously.
