Coin Circle (120BTc.COM) News: Ethereum core developer Tim
Beiko announced on X yesterday (17th) that the Ethereum Goerli test network has completed the Dencun upgrade, which is one step closer to the Dencun upgrade of the main network. Since the EIP-4844 improvement plan introduced in the Dencun upgrade is directly aimed at Ethereum Layer 2 expansion, this has also sparked a wave of discussions in the near future on areas such as Rollups, modularity, and data availability layers.

 V God’s standards for Layer 2

In recent related discussions, a team member of Scroll, the second layer expansion solution for Ethereum, posted on the X platform that although Rollups and Validiums do not share the same security guarantee, he believes that both Rollups and Validiums can be called Ethereum’s L2 .

This argument also attracted a response from Buterin, who said: For me, for something to be fully qualified for L2, it must have stronger security properties than multi-signature, even if it is not a comprehensive guarantee like Rollup.

In order to qualify as L2, a platform or technology needs to have stronger security properties than multi-signature, a basic security mechanism. Even if these security attributes are not as comprehensive as Rollup, they should have their own unique security guarantees.

Furthermore, he once again mentioned Validiums as meeting this criterion. As for Optimiums, Buterin believes it may also meet the standard, but more rigorous analysis is needed to determine their exact safety efficiency.

It is understood that Validium has lower costs and higher throughput than Rollup technology. The main reason is that Rollup publishes transaction data to Ethereum, which requires more expensive fees and limits throughput; Validium also provides ZK (zero-knowledge proof) security is guaranteed, but the transaction data is not published to Ethereum, but is stored off-chain, which means that costs can be further reduced.

 Validium is a better choice for many Dapps

As the Dencun upgrade is approaching, Buterin's statements on many L2s have also attracted attention. In another tweet yesterday, he also said that the core of Rollups is unconditional security guarantee. Even if others collude, users can safely withdraw their assets. .

However, if the data availability layer (Data
Avaliability (DA) relies on external systems, so user assets cannot be completely protected, and the network should belong to Validium. Validium is characterized by the need to sacrifice decentralization, but can use a decentralized data availability layer to ensure the normal operation of its system, thereby increasing network integrity.

It is worth noting that although Ethereum’s current roadmap still focuses on Rollups rather than Validium, Buterin’s recent views also show that he does not exclude Validium; on the contrary, he also pointed out that for many blockchain applications Program-wise, Validium is the right choice, because the use of a good distributed data availability layer system can also improve Validium's security.
