Vitalik: There are four key areas that can be improved in the current L2 protocol:

Vitalik Buterin, co-founder of Ethereum, published an article today titled "Ethereum has blobs. Where do we go from here?" In it, he pointed out that there are four key areas for improvement in L2 protocols:1. More effective use of bytes through data compression;2. Optimistic data technology, using L1 to protect L2 only in special cases;3. Continuous improvement of execution-related constraints;4. Continued improvement of security.Vitalik Buterin also added that Ethereum is basically no longer just a financial ecosystem, but a full-stack replacement for most "centralized technologies", even providing some things that centralized technologies do not have (such as governance-related applications), and now needs to consider this broader ecosystem.

  • Uniswap founder: Founders and VCs need to stop valuing startups and pre-coin crypto projects at more than $1 billion

    Uniswap founder Hayden Adams posted on social media that cryptocurrency founders and venture capitalists need to stop valuing projects at over $1 billion in the early stages of development and before tokens have been released, until they are truly worth that valuation. Building something worth 7-9 figures is an incredible achievement, and not every project needs to be a unicorn at launch. Additionally, Hayden Adams said, perhaps it's naive, but I think raising funds as a founder at a fair valuation (real talent wants upside) and investing at a fair valuation as a VC (LPs want upside) can make more money. It's just harder to do it that way.

  • Chairman of the U.S. SEC: The crypto market is a hotbed of fraud, and investors are not getting the necessary information disclosure on related assets

    According to CNBC, Gary Gensler, the chairman of the US Securities and Exchange Commission (SEC), stated in an interview that the SEC oversees $110 trillion in capital markets, with approximately half in the stock market and half in the bond and other markets. Cryptocurrency is only a small part of the entire market. However, it is a huge part of fraud, deception, and problems in the market, as most of the content in this field does not comply with securities law protection.The SEC cannot talk to any company, but in the field of crypto assets, without prejudging any of them, according to the US Supreme Court's interpretation, many tokens are securities under local law, so we comply with this law, and investors do not receive the necessary information disclosure about these assets.

In addition, Behnam believes that without proper regulation, fraud and manipulation will continue to persist.
  • Vitalik Buterin: ZK-SNARKs and other technologies are inefficient, and Ethereum aims to achieve real-time proofs
