Episode notes
Shared Sequencing Explained
- Sequencing determines which transactions go into a rollup.
- Sharing sequencers allows multiple rollups to coordinate transaction inclusion.
Benefits of Shared Sequencing
- Shared sequencers increase opportunities for double coincidence of wants between rollups.
- This enables atomic transactions across rollups, like buying an NFT on one with cash from another.
Ethereum's Composability Arc
- Ethereum Layer 1 provides a minimum viable composability layer for rollups through asynchronous settlement.
- Shared sequencing and other innovations enhance this baseline composability.
