Ethereum ready to solve blockchain trilemma: Vitalik Buterin

Ethereum's co-founder says PeerDAS and ZK-EVMs have solved crypto's scalability vs. security vs. decentralization trade-off.

Ethereum co-founder Vitalik Buterin claims Ethereum has “solved” one of the biggest challenges in crypto: the blockchain trilemma.

In a Saturday X post, Buterin emphasized the potential of peer data availability sampling (PeerDAS) and Zero-Knowledge Ethereum Virtual Machines (ZK-EVMs), noting that these two upgrades are making Ethereum become “a fundamentally new and more powerful kind of decentralized network.”

“Now, Ethereum with PeerDAS (2025) and ZK-EVMs (expect small portions of the network using it in 2026), we get: decentralized, consensus and high bandwidth,” he said, adding:
