Ethereum co-founder Vitalik Buterin has warned that Layer-2 networks ought to solely transition to full decentralization when their underlying proof techniques are extremely dependable.
In a Might 5 submit shared on X (previously Twitter), Buterin emphasised that advancing to “stage 2″ of decentralization have to be accompanied by strong technical safeguards to keep away from introducing pointless dangers.
He mentioned:
“A great reminder that stage 2 just isn’t the one factor that issues for safety: the standard of the underlying proof system issues too.”
He defined {that a} community’s decentralization degree ought to align with its proof system’s maturity and dependability. Buterin argued that decentralization might trigger extra hurt than good if the system stays error-prone.
Buterin’s remarks are available response to a suggestion by Daniel Wang, founding father of the Loopring Basis, who proposed a brand new label of “Stage 2-BattleTested” to spotlight Layer-2 options which have endured real-world stress circumstances.
In accordance with Wang, such a label would sign that the code has undergone rigorous testing and is extra reliable in stay environments. He added:
“A rollup is #BattleTested if its present code and configs have been stay on Ethereum mainnet for over 6 months, and has persistently secured over $100M in TVL – with no less than $50M in ETH and main stablecoin.”
Buterin illustrates why proof system issues
Buterin acknowledged Wang’s place, whereas illustrating a danger mannequin the place every Safety Council member has an unbiased 10% likelihood of failure.
This consists of potential issues of safety, similar to signing incorrect knowledge, or liveness points that resulted of their unavailability or unwillingness to signal knowledge.
Buterin acknowledged that this mannequin is imperfect because of real-world vulnerabilities, similar to collusion or coordinated hacks, also referred to as frequent mode failures.
Contemplating this, he famous that shifting to stage 2 sooner than modeled might typically be the higher alternative, particularly as proof system high quality improves.
In the meantime, Buterin additionally proposed utilizing multi-signature (multisig) setups with a number of unbiased techniques to cut back the danger of a single level of failure in proof techniques.
He argued that the chance of a protocol failure is carefully tied to the energy of its proof mechanism, particularly in superior safety levels.
The Ethereum co-founder warned that deploying a stage 2 mannequin with a weak, stage-0-level proof system may very well be the worst-case situation.
