Analogy

A sovereign rollup is like an independent nation that rents secure archive space from a larger country. While the sovereign nation publishes its official records in the larger country's archive for safekeeping and (data availability), it maintains its own government, laws, and enforcement (execution and ). The larger country merely ensures the records remain accessible without having any say in how the sovereign nation governs itself or validates its own activities.

Definition

A scaling solution that uses another solely for data availability while maintaining complete autonomy over its , , and governance. Sovereign publish data to a layer but independently determine validity and without relying on the layer's security mechanisms.

Key Points Intro

Sovereign represent a new paradigm in scaling that maximizes autonomy while leveraging external data availability.

Key Points

Maintains complete control over execution, consensus rules, and governance.

Uses an external chain solely for secure data publication, not for settlement or validation.

Can implement any consensus mechanism, virtual machine, or economic model.

Achieves security through its own validator set rather than inheriting it from the base layer.

Example

-based sovereign like Eclipse deploy their own custom environments and rules, while using purely for data availability. If the rollup community decides to change rules or parameters, they can do so independently without requiring approval from governance, maintaining full sovereignty over their chain's operation.

Technical Deep Dive

Sovereign represent an architectural evolution from previous rollup models, distinguished by their separation of concerns: (1) They use the layer exclusively for data availability, publishing batches without relying on its or settlement capabilities; (2) They implement their own mechanism, typically some form of Proof of or variant; (3) They maintain a separate that determines validity and according to the rollup's own rules; and (4) They verify data availability on the layer, typically through techniques, but perform all internally. This architecture differs fundamentally from optimistic or ZK , which inherit security and settlement guarantees from their parent chain. Implementation approaches include using specialized data availability layers like or Avail, posting data to existing blockchains like in a "serverless" fashion, or implementing hybrid designs that publish critical data while maintaining private . The validation model typically involves a separate proof of system with its own economics, conditions, and selection mechanism. Cross-rollup interoperability typically requires custom bridge implementations rather than inheriting standard interfaces from the layer.

Security Warning

Sovereign rely entirely on their own for security, unlike traditional that inherit security from a battle-tested parent chain. When interacting with sovereign , carefully assess their distribution, , and mechanism, particularly for newer deployments with limited diversity.

Caveat

While sovereign offer maximum flexibility and independence, they face unique challenges in bootstrapping security and establishing trust. Without inheriting security guarantees from a parent chain, their security depends entirely on their own economics, potentially creating challenges for newer with limited economic value securing their . Additionally, interoperability with other blockchains typically requires custom bridge implementations rather than leveraging existing standards.
