Thousands of apps.
Thousands of appchains.
In harmony. Conducted by Ethereum.

Spire Labs is announcing our Litepaper for the Based Stack - the next generation rollup framework for building based appchains - and coming out of stealth.

Problem Statement
- Ethereum (liquidity, users, mindshare) is fragmented
- developers don't have a good option to deploy apps

Spire's Based Stack is (yet another😅) deployment option for apps that allows app developers to spin up a custom appchain with based features.

When choosing where to deploy, many apps see the benefits of app-specific chains (appchains) but choose other options because of the flaws with existing appchain infrastructure:

Fragmentation and isolation increase the user acquisition cost for apps on their own appchain.

All of today's deployment options make tradeoffs between scalability, composability, and easy development.

The noisy neighbor problem can be solved by moving to an appchain - but neighbors are great for bootstrapping.

The Based Stack
We believe the tradeoffs and pain points introduced above can be remedied with a small collection of research breakthroughs that, when combined in a highly configurable rollup framework, are extremely powerful.

The next generation of applications is based.

The Based Stack is a rollup framework (analogous to the OP Stack, Polygon CDK, and zkSync’s ZK Chains) that includes native support for based sequencing and other features. The Based Stack is specially designed to support “based appchains” - app-specifc rollups on Ethereum.

The primary research breakthrough that enables composability with the liquidity, users, and protocols of Ethereum is based rollups (or more generally - based sequencing).

Based sequencing is a subset of shared sequencing that includes the Ethereum L1 itself.

For the best of both worlds, the Based Stack also supports traditional shared sequencers such as NodeKit, Espresso, Radius, and Rome.

This is enabled through a new sequencing design called Forward Based Sequencing, designed by Spire Labs.

Based appchains using the Based Stack can also capture the sequencer revenue (MEV) that their applications generate. This can grow an application's revenue by millions of dollars instantly.

The Based Stack also supports based preconfirmations through Preconf RPC and technical partnerships/integrations with multiple leading preconfirmation protocols (to be announced!) to enable subsecond confirmation times for end users of based appchains.

One feature of the Based Stack enabled by based sequencing is Customizable Composability, a practical developer tool to achieve constant realtime read access to Ethereum's state. This feature can be used to access oracles on L1 to save costs dramatically for apps.

And the best part? 
Spire Labs will completely open source the Based Stack with a permissive license, as we continue to develop it. The team is dedicated to building a credibly neutral tool - we don't charge sequencing fees (or any fees for that matter).

Spire’s Based Stack is a tool for creating new appchains as Ethereum L2s that are not (by default) associated with any single “rollup cluster” or “economic zone.” Spire appchains are a part of the economic zone of Ethereum itself.

Blockspace is not homogenous. The Based Stack is highly configurable and allows application developers to customize their deployment environment along a spectrum of tradeoff spaces.

Lastly, we plan to grow our engineering team to build the next generation of Rollups. If you’re interested in building it together, Please contact us through DMs or email hello@spire.dev.
