A zero-knowledge rollup (ZK rollup) is a scaling solution for blockchains, using ZK proofs to verify transactions privately. Scalability has been a longstanding concern for Ethereum. There are more than 180,000 pending Ethereum transactions at the time of writing this. In a live stream during Ethereum’s Shanghai upgrade, the blockchain’s co-founder Vitalik Buterin said: This lack of scalability, combined with Ethereum’s high gas is a recipe for a network disaster. So what's the fix for this? Layer 2 (L2) solutions like state channels, sidechains, and rollups are popping up left & right to make Ethereum more scalable (and thus cheaper) without compromising security or decentralization. In this race to Ethereum scalability, zero-knowledge rollups (or simply ZK rollups) are considered one of the most promising solutions. But, what are zero-knowledge rollups in the first place? How do they improve Ethereum scalability? And which one’s the best? In this blog post, we will explore what a ZK

Scalability has been a longstanding concern for Ethereum. In a live stream during Ethereum’s Shanghai upgrade , the blockchain’s co-founder Vitalik Buterin said : If we don’t fix [Ethereum] scaling before the next bull run, people are going to be stuck paying $500 transaction fees. Layer 2 (L2) solutions like state channels, sidechains, and rollups are popping up left & right to make Ethereum more scalable (and thus cheaper) without compromising security or decentralization. In this race to Ethereum scalability, zero-knowledge rollups (or simply ZK rollups) are considered one of the most promi
