- A type of rollup that does not use a settlement layer to determine its canonical chain and validity rules. Instead, the canonical chain of the rollup is determined by the nodes in the rollup's peer-to-peer network. This means that settlement occurs on the rollup, rather than a separate settlement layer.
- More freedom over the execution environment
- No sharing of computation resources
- Ability to hard fork if something goes wrong
- A rollup chain is sovereign if it does not enshrine a settlement layer to determine the canonical chain and the transaction validity rules of the rollup. Rather, the canonical chain of the rollup is determined by the nodes in the rollup's peer-to-peer network (provided that the blocks are available on the data availability layer). This means that the settlement layer cannot force inclusion of transactions into the rollup.
Sovereign rollups have three key benefits:
