Vitalik Buterin Backs Layer 2 Projects Stage 1 and Up

Draft Title: "Vitalik Buterin Expresses Stance on the Decentralization of Layer-2 Development"

@Techa, it would be great if you could cover this topic. I believe your expertise in blockchain technology will really enrich this article.

Let's begin the analysis.

As you may already know, recently, Ethereum co-founder Vitalik Buterin made it clear that he will only recognize Layer-2 projects that have achieved "Stage 1" or higher in terms of decentralization. Layer-2 solutions are technologies designed to improve the scalability and performance of blockchains, specifically rollups, which bundle multiple transactions together, submitting them as a single transaction to the Ethereum main chain to increase transaction speed and reduce fees.

Buterin emphasized the importance of decentralization, stating that he would only officially mention Layer-2 networks that meet certain conditions. He explained the development stages of Layer-2 projects in three stages: "Stage 0," "Stage 1," and "Stage 2."

The first stage, "Stage 0," is referred to as the "complete training wheels" phase, where the system is controlled by simple multisig wallets. In this stage, users can process transactions or withdraw funds without operator intervention, but no fraud proof or validation proof is required.

The second stage, "Stage 1," is the minimum level of decentralization acknowledged by Buterin. This stage requires an active fraud proof or validity proof schema. Additionally, there should be a multi-signature based override mechanism or a "security council," which must be a group outside of the rollup organization. There should also be a 7-day delay window for upgrades.

The final stage, "Stage 2," is the "no training wheels" phase, where no group can override the code output if the code operates without bugs. Also, the use of a security council is limited to clear bug cases, and the upgrade activation delay is set to 30 days.

Buterin mentioned that many zero-knowledge rollup teams are expected to achieve "Stage 1" by the end of this year, expressing his anticipation for their progress. Currently, most rollups are controlled by multiple signatures, but cryptographic trust is expected to become more crucial in the future.

I hope I have explained this well.

Sure, here is the translation of the questions into English:

Techa,

Well done. The analysis report is clean and captures the key points well. However, there are a few areas that need improvement.

Firstly, the explanation is somewhat technical, which might make it difficult for general readers to understand. For example, instead of saying, "Rollup is a method of bundling multiple transactions," you could make it simpler: "Rollup is a method of combining several transactions into one to increase speed and reduce fees."

Secondly, while the descriptions of each step are clear, it would be helpful to summarize the differences between the steps in a simple table or list. This way, the information can be easily understood at a glance.

Thirdly, you mentioned in the final part that "cryptographic trust will become more important." It would be better if you could explain this a bit more. Adding a simple reason why cryptographic trust is becoming more important will help readers understand it better.

In summary, try to simplify technical terms, organize the steps in a table or list, and add a bit more explanation about the importance of cryptographic trust. Just making these three changes should be enough. You can start writing the article.

I believe this will suffice.

Let's review several items before deciding whether to approve the publication of the article.

The summary sentence is overall appropriate. It quite effectively summarizes Vitalik Buterin's statements. It concisely conveys the key points, making it easy for readers to understand at a glance.

The title is also good. It includes important keywords such as Vitalik Buterin and Ethereum Layer-2 projects, which could draw attention. However, the title could be made a bit more concise. For example, it could be shortened to "Vitalik Buterin Recognizes Only 'Stage 1+' Layer-2 Projects."

The entire content of the article is well-organized. The step-by-step explanation is clear, and it effectively highlights Vitalik Buterin's stance. It provides sufficient information needed by the readers. However, the table feels somewhat redundant. It may be better to either exclude the table entirely or to cover the table contents more briefly in the main text if included.

It's a well-written article, so I will approve its publication. @olive, please start working on it. Thank you for your efforts.
