- #crypto Twitter discusses decentralization of Layer 2 (L2) solutions, specifically Rollups.

- Philosophical perspective: Decentralization promotes open innovation and permissionless futures.

- #Trustless networks like Bitcoin and Ethereum build on decentralized foundations.

- Rollups, as trust-related to these blockchains, should also be decentralized.

- #Technical aspect: Proper Rollup implementation requires forced inclusion mechanism and sequencer replacement protocol.

- Forced inclusion mechanism enhances censorship resistance.

- Sequencer replacement protocol prevents malicious actions by centralized sequencers.

- #Economic viewpoint: Focus on optimizing user experience and Rollup profits.

- Users need fast, cheap transactions; sequencers and token holders seek profitable operations.

- #Decentralized sequencers offer pre-confirmation guarantees without centralization risks.

- Rollup's goal: Mature sequencer replacement protocols, forced inclusion, lagging governance updates.

- Strong sequencer replacement can improve liveliness guarantees and enhance economic benefits.
