Recently, a new concept has emerged in the Ethereum expansion sector - Unstoppable Rollup, a summary that cannot be closed. Let's talk about "unstoppable rolluop" in detail. Official website: https://unstoppablerollups.com1. What is Unstoppable Rollup? Unstoppable Rollup does not refer to a single Rollup project, but a new Ethereum expansion paradigm and philosophical positioning, which originates from the in-depth discussion of decentralization, censorship resistance and data availability within the Ethereum community. Simple understanding: It is a type of Rollup whose design concept emphasizes "cannot be closed/unstoppable". This type of Rollup refuses excessive reliance on centralized sorters, emphasizes permissionless operation mechanisms and trustless data availability (DA), and prioritizes users' "escape" rights (exit games) in the most extreme situations. 2. The core features of Unstoppable Rollup1. Censorship Resistance Nodes cannot arbitrarily refuse users to submit transactions, and users can "force inclusion". 2. Permissionless Sequencer Mechanism Does not rely on centralized sequencers, directly uses the main network for sorting, reducing centralization risks. 3. Independent Data Availability (DA) Mechanism Supports data availability solutions other than Layer1, such as EigenDA, Celestia, or uses Ethereum's own calldata to achieve data assurance. 4. Permissionless Exit Users can freely exit and withdraw assets from Rollup regardless of any failure or attack. 3. Why does the Ethereum Foundation support the Unstoppable Rollup route? The Ethereum Foundation attaches great importance to the "decentralization principle" in the research direction of Rollup. Even if some efficiency is sacrificed, it must ensure that: · Rollup will not become a copy of centralized exchanges · User rights will not be locked in extreme cases · While expanding Ethereum, its core philosophy will not be compromised. Therefore, among many Rollup architectures, Unstoppable Rollup, as a paradigm with the goal of "extreme security and freedom", is highly valued by researchers and core developers. 4. The significance of combining Facet protocol and Unstoppable Rollup 1. What is Facet?Facet is a fork of Optimism that redesigns the convolutional architecture by eliminating all privileged actors in the protocol. While retaining most of the proven features of OP Stack, Facet introduces three fundamental modifications: · Permissionless Sorting: Instead of relying on a privileged sorter, Facet implements a sort-based implementation - allowing any participant to include convolutional blocks on L1. This eliminates the need for centralized sorter selection. · Contract-free Sorting: Facet's sort-based operation does not require any L1 smart contract supervision, eliminating the upgrade vector common in other convolutions. This ensures that privileged contracts cannot be used to prohibit transaction processing. · Native Gas Token: Instead of using a bridged ETH like other OP Stack companies, Facet launched its own gas token - Facet Compute Token (FCT). Any participant can obtain this native asset equally (for gas purposes), eliminating the need for privileged bridge contracts to manage L2's native currency. 2. Facet's milestones Facet V1 was launched in December 2023, upgrading the inscription technology to a new decentralized Ethereum expansion solution. Facet V2 passed the zellic audit in November 2024. Facet V2 was launched in December 2024, rebuilding the underlying protocol, with the programming language consistent with Ethereum, to achieve seamless transfer of ecological applications. At the same time, the centralized authority of the protocol was eliminated, becoming a truly decentralized expansion solution. In May 2025, it received funding from the Ethereum Foundation, becoming the only project in the Unstoppable Rollup route to receive funding from the Ethereum Foundation.
