The ever-evolving landscape of blockchain technology has given rise to rollups, a promising solution for scaling Ethereum in a secure and efficient manner. However, rollup development often involves a phased approach, with varying degrees of decentralization and reliance on centralized control mechanisms. To navigate this complexity, a framework has been established to categorize rollups into three distinct stages based on their "training wheels." 💻👇
Understanding the Training Wheels Analogy
Imagine a child learning to ride a bicycle. Initially, they rely on training wheels for stability and support. As their skills progress, these training wheels are gradually removed until the child can ride independently. Similarly, rollups in Stage 0 utilize training wheels in the form of centralized control to ensure smooth operation during their early development phase. As the technology matures, these training wheels are progressively removed, leading to a more decentralized and trust-minimized system.
Rollup Stages: A Closer Look
Now, let's delve deeper into the three stages of rollup development:
Stage 0: Full Training Wheels
Characteristics: Rollups at this stage are effectively run by the operators. While source-available software allows for state reconstruction from on-chain data (verifying the proposed state root against the actual state), the overall control remains centralized.Example:
$STRK ,
$OP Stage 1: Limited Training Wheels
Characteristics: This stage marks a transition towards increased decentralization. Rollups leverage smart contracts for governance, reducing reliance on operators. However, a Security Council might still be present to address potential bugs or critical issues. Additionally, a functional proof system, permissionless fraud proof submission, and mechanisms for user exits without operator intervention are essential requirements for Stage 1.Example:
$ARB , zkSyncKey Points:Security Council: This council acts as a safety net, but its power is limited. It typically requires a diverse composition and a high consensus threshold for intervention (e.g., requiring approval from a majority of council members).Fraud Proofs: These are cryptographic proofs that allow anyone to challenge an invalid state root. A permissionless system in Stage 1 enables anyone to submit these proofs, fostering community oversight.User Exits: The ability for users to withdraw their funds without relying on the rollup operators is crucial for decentralization. Stage 1 rollups must implement mechanisms that guarantee this functionality.
Stage 2: No Training Wheels
Characteristics: This stage represents the ideal state of a fully decentralized rollup. Smart contracts manage the entire system, eliminating the need for a Security Council or any other form of centralized control. The permissionless fraud proof system from Stage 1 remains, ensuring anyone can participate in maintaining the network's integrity. Furthermore, users are granted ample time to exit the system in case of unwanted upgrades.Example: FUEL, DeGate (not listed on Binance DEX)Key Points:Security Council Removal: With a robust and secure system in place, the Security Council's role becomes obsolete.Enhanced User Protection: Stage 2 rollups provide users with a significant safety net. A minimum exit window (e.g., 30 days) allows them to withdraw their assets if they disagree with proposed upgrades. On-chain bug detection systems can also trigger immediate upgrades in critical situations.
Important Considerations 🤝💥
It's important to remember that the rollup stage framework, developed by L2beat, is an "opinionated assessment of rollup maturity based on subjective criteria." While it provides a valuable lens for evaluating decentralization, it does not necessarily reflect the security of a particular rollup. 😉
Conclusion
Understanding rollup stages is essential for evaluating the maturity and decentralization of these scaling solutions. By categorizing rollups based on their reliance on training wheels, users and developers can make informed decisions about which platforms best suit their needs. As the blockchain ecosystem continues to evolve, rollups are expected to play a pivotal role in scaling Ethereum and enabling the widespread adoption of decentralized applications. DYOR!
