Rollup multisig risk: upgrade keys can still misappropriate funds

Thread206 words
ExplainerL1/L2Ethereum

Explains how multisigs able to upgrade a rollup create security risk: even a zk rollup with a decentralized sequencer set can lose funds if a few signers control upgrades. Applies to smart contract rollups, not sovereign rollups.

Key claims
Multisig upgrade keys let a small group misappropriate funds in a smart contract rollup
The risk does not apply to sovereign rollups
