However, the "blockchain trilemma" suggests that achieving all three simultaneously within a simple architecture is challenging. Ethereum, which currently processes over 1 million transactions per day, often faces high transaction fees due to increasing demand. To address this issue, Layer 2 networks have emerged as an innovative solution.</span>

<br>
<span style="font-size:11pt;font-family:Arial,sans-serif;color:#24292f;background-color:#ffffff;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;" data-raw-html="span">The primary objective of Layer 2 networks is to enhance transaction throughput by achieving higher transactions per second (TPS) while maintaining decentralization and security. These networks achieve this by consolidating multiple off-chain transactions into a single layer 1 transaction. As a result, transaction fees are significantly reduced, making Ethereum more accessible and inclusive for a wider range of users.</span>

There are two main types of rollups: optimistic rollups and zero-knowledge rollups (ZK-rollups). Optimistic rollups utilize fraud proofs to ensure the validity of off-chain transactions, while ZK-rollups employ zero-knowledge proofs to enhance privacy and security. </span>

In October, the average TPS achieved by prominent rollups like Arbitrum and zkSync Era ranged from approximately 9.5 to 10, making them the closest in performance to the Ethereum network among the rollup solutions available. Rollups have collectively made significant contributions to scalability, surpassing the Ethereum mainnet by 321% in throughput, with a scalability factor of 4.21 in October.</span>

In a bear market, attracting and retaining users is challenging for both Layer 1 and Layer 2 networks. Building a prosperous Layer 2 ecosystem requires not only robust solutions but also high-traffic applications. Additionally, the user experience suffers due to the lack of seamless interaction between multiple Layer 2 solutions and between Layer 1 and Layer 2, for example, necessitating wallet switching and incurring liquidity costs.</span>

Indeed, the responses and future directions of other public chains in the face of these challenges are equally tantalizing. The key emphasis remains on ecosystem development and user attraction. The vast expanse of possibilities stretches out before us, as each chain embarks on its own unique path towards scalability and mass adoption. </span>
