Vitalik Buterin, co-founder of Ethereum, has issued a harsh warning to developers of Rollup-based L2 system solutions.
X-post is the co-founder of Ethereum It was pointed out Achieving stage 2 on an L2 network is important for security. However, he argued that strengthening the underlying proof system is equally essential. He added that rushing to stage 2 without significantly improving the reliability of the proof could actually increase the likelihood of failure.
One concern for Buterin is that many rollups, as he explained, still rely on the centralized control mechanism “training wheel.” It helps you roll the ball, but it can also be a single point of obstacle that hinders progress unless it is replaced by a robust, decentralized alternative.
He emphasized that the rollup is vulnerable to attacks and operational failures without proper security measures such as fraud, proof of validity, threatening user trust and damaging the broader Ethereum ecosystem.
Daniel Wang suggests adding a “Battle Tested” label to the two rollups
Buterin’s post came in response to the proposal that Loopling founder and CEO Daniel Wang would have another label for Stage 2 Battletested-lease for improved security.
Loop ring CEO Claim If the code has been posted on Ethereum mainnet for more than six months and maintains a $100 million TVL with at least $50 million in Ethereum and a major stubcoin, then the rollup can be categorized as battletested.
He also suggested that bat tested status should not be permanent. Any changes made to the rollup must require you to go through the qualification process again to acquire the label.
Again, it doesn’t matter if the rollup is in stage 2 or not. Rollups are eligible for the label battletededed.
In response to the King’s proposal, Butalin said: “Remind me that Stage 2 is not the only thing that matters to security. The quality of the underlying proof system is also important.”
Dominick John, an analyst at Kronos Research, argued that if a system can be proven reliable under economic stress as well as the design of a theoretical proof system, then it is truly decentralized.
He added that before shifting from stage 1 to stage 2, the roll-up team must also be prepared for the risks of threatening network security.
Buterin: Rollup should hit Stage 2 only with a powerful proof system
Another X post, Buterin I explained in detail The best time to move to Stage 2 with a mathematical model.
In his model, he made the following assumptions: each Security Council member could have a 10% failure rate, liability failures and safety failures as well, with the Stage 0 Security Council being four-sevenths and Stage 1 being six-eighth.
Taking these assumptions into consideration, he argued that as the quality of the proof system increases, the optimal stage shifts from stage 0 to stage 1 and ultimately to stage 2. This means that if stage 0 or 1 increases over stage 2, it becomes more reliable.
With these hypotheses he argued that as the proof system strengthens, the peak level moves from stage 0 to stage 1 and to stage 2. Therefore, stage 0 or 1 is more reliable as the probability of failure increases compared to stage 2.
He further suggested that using a multi-sigproof system reduces the chances of system collapse.
Additionally, Mike Tiutin, Chief Technology Officer of the distributed compliance protocol PureFi, provides a perspective on this topic and believes early decentralization could undermine system security.
Similarly, Chronos analyst John argued that decentralization should be viewed as a common responsibility of the crypto ecosystem, not race. In stage 1, councils can intervene to help if the system breaks, but in stage 2, stepbacks include millions of dollars, he said.
