Ethereum 2.0 is still in progress. We are still waiting for the next launch to take the next step towards the cryptocurrency created by Vitalik Buterin. However, one developer has strongly criticized both this new implementation using Proof of Stake (PoS) and the rollup that promises to improve the ability of the network to check transactions.
Hugo Nguyen, founder of Bitcoin (BTC) wallet Nunchuk, posted a Twitter thread providing a discussion against the rollup of Ethereum.Let’s show Why, according to their analysis, they are not scalability solutions, but systems with serious security issues. These issues will be further emphasized with the advent of Ethereum 2.0.
Rollup is a protocol that is responsible for “wrapping” transactions on the second tier. This increases the transaction capacity per block. However, in Hugo Nguyen’s words, “no one protects second-tier transactions.”
Becoming a verifier on some rollups (Optimistic or ZK) requires Layer 1 and Layer 2 nodes, which requires a fairly expensive infrastructure. According to Nguyen, these types of scenarios may indicate the potential for centralization. This is because fewer users are less willing to invest in having their own nodes, and this layer 2 is “no validators at all”.
To the dilemma of having Layer 1 and Layer 2 nodes, we need to add the exponential growth that the Ethereum blockchain had last year. The heavier the weight, the higher the hardware cost.
Regarding centralization, Vitalik Buterin himself points out in a recently released roadmap known as the Endgame that this scenario is possible for the following reasons: Cost per node roll up Or a second coat solution. However, Vitalik shows that as long as the base network (Layer 1) is strong, the centralization that the rollup can present can be modified.
Ethereum 2.0 and roll-up punishment system
For Nguyen, Vitalik and a group of developers are trying to create a “non-codeable” judicial system. This is because Ethereum 2.0 introduces a new system that punishes malicious nodes by removing some of the ETH that has accumulated on the staking.
This system brings justice to the node trying to create a malicious transaction. But there is a serious problem Nguyen has pointed out: who will be punished and who will benefit.
The developers point out that in this system, the validator node that detects “fraud” is the beneficiary, not the victim. This is because the funds from the malicious node (discounted as a punishment) are paid to the verifier, not the address of the potential fraudulent person.

In a thread (of over 50 tweets), Nguyen summarizes that rollups aren’t the answer to scalability. Take plasma as an exampleAnother tier solution, created by the abandoned Vitalik himself. According to the creator of Nunckuk, rollups can follow the same fate.
He points out that searching for a solution doesn’t really take anything for granted. In Problem A, they look for Solution B, which also has a problem and Solution C is presented, which is also vulnerable. He explains that this is creating an unstable network.
Vitalik Buterin puts a lot of bets on rollups as some of the current Ethereum 1.0 currently defines networks in Proof of Work (PoW) and more in Ethereum 2.0. doing. Developers in Russia and Canada have put together a roadmap outlining how these solutions can contribute to the growth of the network, but this is not yet known.
