Just when everyone argued that Ethereum “DA orthodox” @Vitalikbuterin, they were all discussing the definition of Layer2.
Indeed, Layer2’s naming can easily correspond to Rollup directly, and since it is Rollup, DA is not questioned by the main network.
Because Ethereum’s capacity expansion scheme, there are PLASMA, ROLLUP, VALIDIUM, etc.:
Plasma strictly restricts that DA must be on the main network; Rollup is relatively broad, and you can mix all DAs in the main network. For example, most of ZK-Rollup will compress the data on the chain. The calculation of the environment under the chain is finally based on ZK.Synchronous to the chain;
Validium is even more flexible. DA is completely under the chain. You only need to calculate the end to submit Snark to the main network to ensure that data consistency can be ensured.
In fact, these types of expansion schemes are all three impossible triangle problems.
From the perspective of expansion, each has its own advantages and disadvantages. For example, Plasma is suitable for a second -layer payment solution for security guarantee. Validium is suitable for more scalability independent application chains. Rollup can become the mainstream because it takes a folding TradeOffFFFFFFFFFFFFFFEssence
Therefore, Vitalik believes that the definition of Layer2 is too narrow. It can be divided into Strong L2 and Light L2 based on Security or Scale preferences. Only in this way, the Layer2 industry will not be limited by Rollup.Vision.
So the question is, can only let LOLLUP be retained?Vitalik also gives an explanation (reviewed 4 points mentioned by Vitalik):):
1) Validium is more secure than some of the Rollups that is governed by multiple visa. This actually means that if a capacity expansion scheme uses a chain DA but the result is synchronized to the main network in the form of SNARK, the main network can trace back and ensure the integrity and correct data of the data.sex.
This level of security is compared to the RollUp solution that can be guaranteed by the multi -signing governance committee. In fact, Validium is better.Although RollUp is more popular, it is not recognized if it only rely on Multisigs to ensure security; this is because the Rollup project should make up for the defects of the main network Rollup solution dependence on the security guarantee.
2) Strict Rollups solutions will be better than Validium. This is actually saying that rollup can ensure the availability and integrity of the chain of the data. Ethereum Validators have the ability to verify and ensure safety.The way of mechanism is more direct and pure.
It is precisely because of this that everyone pays too much attention to Rollup that cause Validium to look illegal; this seems to emphasize the legitimacy of Validium.
3) Snarks+under -chain DATA security is better than fraudulent certification on the pure chain, because the Snarks on the chain can at least ensure the consistency and integrity of the data under the chain.The challenge chain challenge challenge is safer than the latter in actual application scenarios.
This is actually a scheme that criticizes some data under the chain and depends on the chain.Fortunately, such schemes are not uncommon. Most of the data using the chain fraud certificate are also on the chain;
4) Finally, Vitalik also emphasized that rollups are not equal to Layer2. There are also many opportunities for directions such as Plasma and Validium, and Layer2 cannot be limited to the Rollup level. If it does not work, the definition of Layer2.
In my opinion, Vitalik stands out like this to peel off the definition of Rollup and Layer2, because once everyone’s cognitive Layer2 becomes Rollup, the invasion of third -party DAs such as Celestia will fall into passive.
This time open the concept from high, developers want to use a third -party DA like Celestia, then if you go to the main network, it is the Validium expansion solution of Ethereum. In addition, developers can also do it based on ZK+Plasma.Exploring a vast capacity expansion scheme.Regardless of how the market changes, Ethereum always “defines” everything.
It is not difficult to see that Ethereum’s Lego Building supports the forward -looking thoughts of Vitalik Takaju Jianyu!
