Buterin Reconsiders Ethereum Layer 2 Complexity Concerns Before Shanghai Upgrade
-
Vitalik Buterin is concerned that pushing too much complexity to Ethereum layer 2 solutions could introduce extra risk if there are bugs. If an L2 has a failure, people could permanently lose money.
-
Buterin was responding to and mostly agreeing with a tweet criticizing people who overstate L2 capabilities.
-
Buterin concludes it may be worth adding some sophisticated L1 features to reduce L2 code burden and keep them simple.
-
Buterin seems to have changed his stance on keeping Ethereum mainnet simple, compared to comments he made in 2019.
-
His comments come just before the upcoming Shanghai upgrade that will increase L2 speeds and reduce costs.
