New post ✍️ ✍️ : How shared settlement + coordinated sequencing unlocks synchronous composability for appchains

https://paragraph.xyz/@spire/l3-based-stack

Spire is building the Based Stack. spire.dev

Spire introduces (1) Shared Settlement + (2) Coordinated Sequencing — a new execution model that enables synchronous composability across rollups.

Instead of isolated appchains, Spire enables L3s to execute in a single sequencer batch.

The problem: rollup fragmentation creates liquidity islands.

Each appchain operates with its own sequencer and settlement layer, leading to:

🚧  Capital inefficiency
⏳  Delayed execution
🔄  Fragmented price discovery
❌  Cross-domain execution risk

Spire is building the Based Stack to help apps launch their own based rollup L2. As ecosystems evolve, a new frontier is emerging - based L3s. 

This post explores how Spire’s approach can enable rollups to sync execution beyond L2s. 🧵
