Overview

What is an Unstoppable Rollup?

An Unstoppable Rollup is a rollup that cannot be interrupted without compromising the L1. No exit windows, no security councils, no admin keys.

Ethereum rollups secure tens of billions in user assets, yet almost all can be halted or censored by a handful of admin keys. Even the most "decentralized" rollups today can be stopped by fewer than 20 people.

Facet is the only rollup that cannot be stopped. If Ethereum is running, Facet continues running. Period.

The Problem with Traditional Rollups

Today's rollups have a fundamental vulnerability—they can be stopped by a small group of people:

  • Disable the Sequencer - A single multisig transaction can halt block production

  • Overwhelm Forced Inclusion - Gas limits drop 99%, creating functional stoppage

  • Disable Forced Inclusion Entirely - Contract upgrades can remove censorship resistance

These aren't theoretical. In 2024 alone, Linea halted block production, Blast blocked force-inclusion, and Soneium censored specific tokens.

The Facet Solution

Facet eliminates all forms of admin control through four fundamental architectural decisions:

  1. Immutable Sequencing - Transactions go directly to an immutable L1 address

  2. Native Gas Token - FCT is minted algorithmically, no bridge admins

  3. ZK Fault Proofs - Immutable proof system with no overrides

  4. Fork-Based Upgrades - Changes only through user choice

Fork-Based Upgrades: True User Sovereignty

Traditional rollups force upgrades on users—15 signatures change the protocol, and everyone must accept it or exit. Facet upgrades work like Ethereum L1: through forks and social consensus.

How It Works:

  1. Deploy new system with updated rules

  2. Users decide which version to follow

  3. Old version continues running forever

No one can force you to upgrade. Ever.

Just like Ethereum Classic still exists alongside Ethereum, multiple Facet versions can coexist based on user choice.

Why This Matters

For Users:

  • Your assets are safe—no admin can freeze withdrawals

  • Guaranteed inclusion—if Ethereum runs, your transaction goes through

  • True ownership—no one can take away your ability to transact

For Developers:

  • Build without permission—deploy whatever you want

  • No admin approval needed

  • Design with version flexibility for true decentralization

For Ethereum:

  • A rollup that actually inherits L1's security properties

  • No compromise on decentralization

  • Proof that unstoppable rollups are possible
