"The Espresso Revolution: What Happens When Rollups Talk to Each Other?"

1/
Today, rollups don’t talk.
Starknet can’t sync with Arbitrum. Optimism can’t natively talk to zkSync.

But Espresso Systems is building a bridge — not for tokens, but for time.

Let me explain. 🧵👇

2/
Each rollup has its own sequencer — it decides the order of transactions.

When these sequencers are independent, rollups become silos.
→ Cross-rollup composability dies.
→ Devs are forced to build for one chain only.

3/
Espresso’s answer?
A Shared Sequencer Network.

This means multiple rollups can share a global ordering system — one that’s fair, auction-based, and permissionless.

4/
🎯 The benefit?
If two rollups share Espresso as their sequencer, a contract call on Rollup A can influence Rollup B in the same block.

That’s instant composability.

5/
They back this with HotShot: a BFT-based consensus protocol that finalizes blocks in seconds and secures the sequencer from malicious behavior.

So even if one sequencer fails — the system doesn’t.

6/
Their DA stack, Tiramisu, is layered for flexibility:

🥇 Cocoa: fast, trusted
🥈 Mascarpone: mix of trust/minimal fraud
🥉 Savoiardi: full-on validity + decentralization

Each layer fits a different rollup’s needs.

7/
It’s not just theory:

Rari Chain is already using Espresso

Cartesi and LogX are integrated

Ecosystem is growing before token even launches

8/
This is how you build lasting infra:
✅ Dev-first
✅ Scalable
✅ No hype-farming
✅ Backed by serious capital

Stay early.
Stay caffeinated. ☕
