Ethereum Layer 2s : ZK Rollups vs Optimistic Rollups

Similar to numerous other Layer 1 blockchain networks, Ethereum has grappled with scalability issues over an extended period. These challenges largely stem from the network’s linear processing of transactions, which leads to congestion during high traffic, resulting in prolonged transaction times and escalated fees.

These hurdles have significantly hindered blockchain adoption across various industries. To address them, developers are intensely focused on devising scaling solutions that bolster speed, augment throughput, and minimize transaction expenses, thereby ensuring blockchains can effectively cater to the demands of contemporary digital ecosystems.

Among the array of solutions, rollups have emerged as a particularly promising innovation. This article delves into a comparison between two distinct rollup methodologies: Optimistic versus Zero-Knowledge (zk).
