Restaking protocol EigenLayer<\/a> and rollup solution provider AltLayer have introduced<\/a> a concept called \u201crestaked rollups,\u201d which could solve key issues for Ethereum scaling.<\/p>\n To that end, AltLayer is offering three services which will, in theory, allow developers to quickly spin up their own app-specific rollups, without sacrificing decentralization or compromising on speed.<\/p>\n AltLayer calls these actively validated services (AVS). EigenLayer allows users to \u201crestake\u201d their ETH liquid staking tokens (LSTs) to secure other services beyond Ethereum. In the context of the partnership, EigenLayer provides the security for AltLayer\u2019s AVS to secure many rollups at once.<\/p>\n Rollup networks, which are Layer 2 scaling solutions for Ethereum, have been a recurring theme this year, attracting more than $16B of assets to their chains. Arbitrum is currently the leading L2, with roughly half the sector\u2019s total value locked (TVL)<\/a>.<\/p>\n However, spinning up a rollup that offers fast and cheap transactions without compromising on decentralization has proved to be a massive technical challenge.<\/p>\n The biggest hurdle for rollup developers lies in sequencers, key pieces of software responsible for ordering, processing and aggregating transactions on a rollup before posting their results to the main chain.<\/p>\n Currently, leading rollups like Arbitrum and Optimism control their own sequencers. With the use of such centralized sequencers, the projects could potentially rearrange transactions to favor certain parties \u2014 which would be antithetical to decentralization.<\/p>\n However, as AltLayer points out<\/a>, the teams\u2019 reputation and the number of people observing major chains like Aribitrum and Optimism have made centralized sequencers an acceptable design choice, at least in the short term.<\/p>\n This centralization risk increases when dealing with individual developers looking to spin up a small-scale rollup. Enough people aren\u2019t watching the chain, so it\u2019s hard for such projects to develop user trust.<\/p>\n Despite this, tooling has emerged for developers to deploy their own rollups \u2014 Arbitrum, Optimism, and others have released software development kits (SDKs) to simplify the process. These SDKs don\u2019t provide all the tooling to make small-scale rollups strongly decentralized, which is where AltLayer and Eigenlayer are looking to step in.<\/p>\n Start for free<\/a><\/div>\n Eigenlayer and AltLayer are part of an emerging design paradigm in the Ethereum space centered around modular blockchains<\/a>. The core idea is that developers can pick and choose different providers to take on various aspects of a rollup\u2019s architecture.<\/p>\nCentralization Challenges<\/h2>\n
