Vitalik Buterin emphasizes the risk of weak evidence systems in the Ethereum Layer-2 rollout

The co-founder of Ethereum Vitalik Buterin has warned that Layer-2 networks should only pass to a complete decentralization if your underlying evidence systems are very reliable.

In an article divided on X (formerly Twitter), but the Bauterin emphasized that the progression to “level 2” must be accompanied to the decentralization of solid technical protective measures in order to introduce unnecessary risks.

He said:

“A good memory that level 2 is not the only thing that is important for the security: the quality of the underlying evidence system is also important.”

He explained that the level of decentralization of a network should match the maturity and reliability of the proof system. Buterin argued that decentralization can cause more damage than benefits if the system remains prone to errors.

In response to a proposal from Daniel Wang, the founder of the Loopring Foundation, which has proposed a new label of “level 2-protected” to emphasize the solutions of the Layer 2, which have endured real stress conditions.

According to Wang, such a label would signal that the code has subjected strict tests and is more trustworthy in live environments. He added:

“A rollup is #battlettested if the current code and its configurations have been secured on Ethereum Mainnet Live Live Live Live and over 100 million US dollars in TVL for over 6 months – with at least $ 50 million in ETH and Major StableCoin.”

Buterin illustrates why Proof system is important

Butterin recognized the position of Wang and at the same time illustrated a risk model in which each member of the security council has an independent probability of failure of 10%.

This includes potential security problems such as the signing of incorrect data or problems with liveliness, which can be signed for their non -availability or unwillingness.

Butterin admitted that this model is imperfect due to real weaknesses such as agreements or coordinated hacks, which are also called common mode failure.

In view of this, he found that the move to level 2 earlier than modeled may be the better choice, especially if the quality of the Proof system improves.

In the meantime, butterin also suggested that multi-sig setups (multi-signature) with several independent systems reduce the risk of a single error point in evidence systems.

He argued that the likelihood of a protocol failure was closely associated with the strength of his mechanism of evidence, especially in advanced safety phases.

The co-founder of Ethereum warned that the provision of a stage 2 model with a weak proof system of the Stufe-0 could be the worst-case scenario.
