After the Based Stack launches and is ready for production use, the Spire Labs team will continue improving the rollup framework.

Some specific things we are thinking about:

* ZK Proof Aggregation / Shared Deposits: Enabling cheaper bridging between participating appchains. We are interested in collaborating with other teams on this.

* [Blob Aggregation](/education-hub/blob-aggregation): Building tools to enable efficient sharing of blob space on Ethereum to minimize DA costs for lightweight applications.

  * [A design to optimize blob space for appchains/rollups 🧵 ↗](https://x.com/Spire_Labs/status/1871421121264034289)

* Diverse Execution Environment / VM Support: Integrating and developing important features to support alternative VMs and next-gen execution environments natively.

* Realtime Proving: Enabling synchronous composability with Ethereum. We are looking into many designs related to this, including fast ZK proving and also TEE proving.
