# Taxonomy

## Standard rollups

Standard rollups (on Ethereum) are validated and settled through smart contracts.

## Sovereign rollups

Sovereign rollups (on Celestia) leverage the base layer protocol for consensus and data availability.

## Enshrined rollups

Enshrined rollups ([domains](https://academy.autonomys.xyz/autonomys-network/decoupled-execution/domains) on Autonomys) are directly integrated into the core consensus protocol of the underlying blockchain, ensuring the rollup's features and functionality are maintained and enforced by the network's consensus rules. This built-in support enhances the rollup's security, interoperability and adoption, while providing the benefits of a typical rollup, such as increased throughput and reduced transaction fees.

Domains extend Celestia's sovereign rollup model to include shared settlement by default by allowing operators to re-stake (as proposed by Free2Shard and implemented by EigenLayer on Ethereum). Autonomys enshrines the re-staking model within the semantics of the core protocol (unlike EigenLayer, which is implemented through smart contracts).

Although similar to Polkadot parachains, domains support a modular validation framework and permissionless deployment, unlike parachains' monolithic validation model and permissioned deployment. Domains also have shared security and trust-minimized interoperability as they are validated and settled on the consensus chain (unlike Cosmos zones and Avalanche subnets).
