It wants to stay decentralized, reach agreement without a central authority, and handle more activity without slowing down. This tension is often called the blockchain trilemma.
According to Ethereum cofounder Vitalik Buterin, that balance is no longer theoretical. It is now running in live code. With PeerDAS active on mainnet and ZK EVMs reaching alpha quality, Vitalik says Ethereum is becoming a fundamentally new kind of decentralized network.
This matters because it changes what Ethereum can support at scale. These upgrades are not small speed tweaks. They reshape how data and computation move across the network, opening the door to far more users and applications.
From Replication to Real Distribution
Vitalik explained the shift by comparing Ethereum to earlier peer to peer networks. BitTorrent showed how a system could be highly decentralized and move huge amounts of data, but it had no shared truth. Bitcoin added strong consensus, meaning everyone agrees on the ledger, but it kept bandwidth low by copying the same work across all nodes.
Ethereum with PeerDAS and ZK EVMs aims to combine the best of both. PeerDAS, short for peer data availability sampling, lets nodes check that data exists without downloading everything. This reduces load while keeping security. ZK EVMs, or zero knowledge Ethereum virtual machines, allow blocks to be verified using math proofs instead of redoing all the work. Performance is now production ready, with safety checks still being refined.
Now that ZKEVMs are at alpha stage (production-quality performance, remaining work is safety) and PeerDAS is live on mainnet, it’s time to talk more about what this combination means for Ethereum.
These are not minor improvements; they are shifting Ethereum into being a…

A real world example helps. Think of a global video call. Instead of every device recording and sending the full video stream, the work is shared and verified. Everyone trusts the call without carrying the full load. That is closer to how Ethereum will operate.
Recent trends back this up. Rollups already handle more than 80% of Ethereum transactions, according to L2beat data. These scaling layers rely on the same ideas of shared data and proof based verification that PeerDAS and ZK EVMs strengthen.
More About Ethereum
Stablecoin transfer volume on Ethereum surged past $8 trillion in Q4-2025, setting a new all time high and underscoring Ethereum’s role as the backbone of stablecoin activity. The milestone shows growing real world use, as stablecoins are increasingly used for trading, payments, and cross border transfers.
