This talk will act as a river guide exploring the design space for L2 sequencer decentralization. It will cover: 1. Should L2’s care about decentralizing a sequencer? 2. What does it mean for UX? 3. Forced Inclusion ≠ Decentralised sequencing 4. ELI5 the approaches being taken by L2's 5. Based rollups to the rescue? 6. What are for optimistic / zk and / privacy rollups 7. L2 Consensus networks are not the solution 8. Decentralisation is not just about sequencing rights
