🧵shared sequencers: the hidden game behind L2 neutrality

1/ Rollups scale Ethereum. But right now, they’re… kinda lonely. Each L2 has its own sequencer — deciding which transactions go first. This is fine... until it's not. 👇 2/ If the sequencer is down? No blocks. If it’s malicious? It can reorder, censor, or MEV the hell out of you. Sequencer centralization is rollup’s dirty secret. 3/ Enter: shared sequencers. Instead of each rollup building its own infra, they plug into a shared layer. This adds resilience, neutrality, and possibly cross-rollup atomicity. But it’s not that simple. 4/ The challenge? Latency tradeoffs Fair ordering guarantees Who gets to run the sequencer network? How do you enforce neutrality? Shared sequencers help decentralize… but also concentrate power in new places. 5/ The L2 wars won’t be won by TPS or TVL alone. It’ll come down to… who controls the sequencer? #Finance #MakeMoney
