‘Increasing Ethereum’s bandwidth is safer’ – Vitalik Buterin explains why

In his latest technical deep‑dive, Ethereum [ETH] co‑founder Vitalik Buterin is urging a reality check rooted in fundamental physics.

He argues that the network should stop chasing unrealistic latency benchmarks. Instead, he believes Ethereum must focus on scaling bandwidth.

According to Buterin, the real path to Ethereum’s dominance lies in how much data the network can process. It’s not about the speed of a single transaction, but about the overall capacity to handle volume efficiently.

This shift in perspective highlights a more sustainable approach to Ethereum’s long‑term growth.

Buterin said, 

He further added,

What is Buterin trying to chase?

Buterin’s core argument lies in the fact that he sees Ethereum as not a world-scale video game server, but the world’s heartbeat.

In modern high-performance networking, latency is constrained by the speed of light.

Meanwhile, Bandwidth, on the other hand, is an engineering challenge, not a physical limit.

By using PeerDAS and Zero-Knowledge Proofs, Buterin argues that ETH can scale data capacity dramatically without sacrificing decentralization.

While transaction speed is capped by physics, data volume can be spread across a broad network of home stakers instead of concentrated in elite infrastructure hubs.

This approach underpins what Buterin calls the “Walkaway Test” and the need for geopolitical fairness.

For context, if staking from financial centers consistently outperforms home setups, centralization becomes unavoidable. Hence, to prevent this, Buterin says that Ethereum’s economics must favor global participation by default.

This will result, Layer 1 remaining intentionally slow and planet-scale, while faster execution moves to Layer 2s.

Comparison with Linux and BitTorrent

Additionally, to make this layered complexity intuitive, Buterin also draws parallels from open-source history.

He said, 

BitTorrent helps move massive amounts of data without a central boss, whereas Linux proved that an open-source “core” could run the entire world’s internet.

Drawing a comparison, Buterin’s vision is to combine the two.

He wants Ethereum to be a “neutral zone” where purists get total control over their money without any middleman, like BitTorrent.

And, corporations get a rock-solid foundation that won’t crash or change the rules on them, like Linux.

ETH price action

Meanwhile, on the price front,  Ethereum was trading at $3,114.84 at press time, after a 3.19% decline over the past 24 hours, as per CoinMarketCap.

Yet, ETH has already outperformed Bitcoin [BTC] by nearly 2x, posting a 9.3% weekly move as 2026 began.

Finally, if momentum persists, ETH, backed by its expanding economic role and structural thesis, could deliver a higher ROI than Bitcoin by the end of Q1 2026. 

Final Thoughts

• Ethereum’s refusal to chase speed reflects a long-term bet that resilience outlasts performance theatrics.
• Vitalik Buterin’s thesis positions Ethereum as infrastructure first, product second.
