Coin Circle (120Btc.coM): Vitalik, founder of Ethereum
Buterin just responded to community comments on Twitter, clearly expressing his definition of Validium and saying that it is the right choice for some applications to be built on Validium rather than using Ethereum as the DA Rollups.

 The decentralized network that does not use Ethereum is Validium

 The definition of Validium raises the topic again

With the recent Cancun upgrade (Dencun) being inevitable, the EIP-4844 that will be introduced may bring about ecological changes in Layer 2, so the topics of keywords such as modularization, Rollups, data availability layer, and Layer 2 continue to heat up and move. Compete on the stage.

Among them, the issue of the definition and legitimacy of Rollups was mentioned again. ZK-, which focuses on the first type of Rollups
EVM project Taiko, its founder @danielwang.eth tweeted today that any Ethereum that uses an external data availability layer (DA)
Rollup can be regarded as the definition of Validium, but these remarks prompted Vitalik's reply.

 Buterin agrees that some services should use Validium

Vitalik agrees. The core of Rollups is unconditional security, which means that even if others collude, users can take out their assets. If the data availability layer relies on external systems and this cannot be done, the network should be Validium.

While sacrificing some decentralization, Validiums can use the decentralized data availability layer to ensure the normal operation of the system and enhance network security. These trade-offs will be nuanced decisions based on specific application needs.

However, Vitalik did not reject Validium. It said that Validium is the right choice for many applications because using a good decentralized data availability layer system can really improve Validium security and is a good way to do it.

Previously Vitalik elaborated on the advantages and disadvantages of various L2s:

 The Ethereum roadmap is still centered on Rollups

The Ethereum roadmap is still centered on Rollups rather than Validium, but judging from today’s post, Buterin does not seem to reject the value capture conflict between Validium and Ethereum.
