In latest 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 lowering latency (pace of transaction processing).
His core argument rests on the distinction between what’s troublesome and what’s bodily not possible. Lowering latency, which primarily means the time it takes for a transaction to be confirmed, is essentially constrained by the pace of sunshine, amongst different issues:
“We’re essentially constrained by the pace of sunshine, and on high of that we’re additionally constrained by […] must assist nodes in rural environments, worldwide, and in house or business environments exterior of information facilities, must assist censorship-resistance and anonymity for nodes, and many others… [Quote shortened for editorial purposes].”
Though it sounds difficult, there’s a comparatively easy option to visualize this idea.
The Freeway Analogy: Bandwidth vs. Latency
To finest perceive what Buterin speaks about, image Ethereum as a freeway. The issue is traffic-related – you need to transport extra folks.
You solely actually have two choices:
- Scale back the latency (pace) of transportation by making each automobile drive so much faster.
- Improve the bandwidth (capability) of the freeway by constructing extra lanes.
Buterin argues that Ethereum ought to go together with the second possibility as a result of attempting to make the vehicles journey faster is harmful and essentially constrained.
This additionally ties to a different put up he wrote 5 years in the past titled The Limits to Blockchain Scalability. In it, Ethereum’s co-founder mentioned a tweet by Elon Musk:
Ideally, Doge hurries up block time 10X, will increase block measurement 10X & drops payment 100X. Then it wins arms down.

Vitalik outlined how difficult that is with out sacrificing safety and decentralization. In essence, he argued that common folks ought to be capable to run nodes on their normal tools (corresponding to laptops), that means that the blockchain is of course constrained by the capabilities of this tools. The choice is for nodes to be run by way of knowledge facilities, which dangers centralization:
The elites of your blockchain group, together with swimming pools, block explorers and hosted nodes, are in all probability fairly well-coordinated; fairly doubtless they’re all in the identical Telegram channels and WeChat teams. In the event that they actually need to arrange a sudden change to the protocol guidelines to additional their very own pursuits, then they in all probability can.
That mentioned, he additionally mentioned that latency can, certainly, be diminished with current 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 accessible chain with a smaller node rely per slot (eg. 512 as an alternative of 30,000), which might take away the necessity for an aggregation step, permitting your entire sizzling path to occur in a single subnet.
In keeping with Buterin, this alone can scale Ethereum by three to 6 occasions and is “very a lot within the realm of risk.”
The World Heartbeat
And but, this specific technical divergence defines Ethereum’s final function – to be the World’s Heartbeat as an alternative of the World’s Video Sport Server.
He argues that with current applied sciences corresponding to PeerDAS and ZKPs, the means to scale exist and Ethereum might be scaled 1000’s of occasions, a minimum of in comparison with the present establishment. He additionally outlined that the numbers grow to be much more favorable than earlier than, and that there is no such thing as a constraint that stops “combining excessive scale with decentralization.”
Following my earlier analogy, this merely implies that there’s nothing stopping the workforce from constructing a freeway with as many lanes (probably 1000’s) as wanted.
Nonetheless, 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 parts. This additionally implies that layer two scaling options will proceed to have a task sooner or later, even when Ethereum is scaled tremendously.
