## Description

In “Sequencers in Layer 2 Scaling Solutions and Beyond”, we will explore the key role of sequencers in L2 solutions, where they are responsible for ordering and executing transactions. I will highlight the prevalence of centralized sequencers in current L2 solutions, their benefits in terms of performance, but also the concerns related to centralization, security, and potential censorship. Then I will delve into decentralized sequencers, which utilize a decentralized network of nodes to perform sequencing, aiming to address the issues associated with centralization. Additionally, I will cover the emergence of shared sequencers, which allow multiple rollups to share a single decentralized network of sequencers, providing interoperability advantages between rollups.
