Episode notes
Permissionless Chains Provide Superior Market Transparency
- Permissionless chains provide rich, transparent on-chain data that benefits regulators, institutions, and builders.
- Rebecca Rettig argues that mempools and open visibility reduce information asymmetry compared with opaque institutional systems like Canton.
Reframe MEV As Transaction Ordering Value
- MEV has been reframed by Rebecca Rettig as transaction ordering value (TOEV) with both negative and positive forms.
- She notes institutions already pay for priority (co-location, feeds), so some ordered execution value is legitimate.
Choose Chain Type And Implement Kill Switches Deliberately
- Build honestly: choose permissioned chains for narrow institutional use cases and permissionless for broader markets.
- Rebecca suggests implementing kill switches at the application layer if needed, accepting regulatory obligations for that choice.
