Ethereum co-founder Vitalik Buterin believes the Bitcoin network needs scalable solutions like zero-knowledge rollups (ZK-rollups) to become more than another payment network. Buterin’s comments came during a Twitter Space hosted by Bitcoin developer Udi Wertheimer, with discussions revolving around Ethereum’s scaling experiments.
A ZK-rollup is an off-chain protocol that operates on top of the Ethereum blockchain and is managed by on-chain Ethereum smart contracts. It offers a more scalable and faster way to verify transactions without sharing critical user information.
