How it fits together

Isometric diagram: Ethereum validator set at the base, Puffer preconf coverage layer above it, four connected rollups on top.

Staking makes a validator set
ETH staked with Puffer runs validators on Ethereum, earning PoS yield and building the validator set everything else rests on.
More validators, higher preconf coverage
The more validators in the set, the more of Ethereum's blockspace Puffer Preconf can commit to ahead of time.
Puffer UniFi uses preconf for synchronous composability
Puffer UniFi builds on that coverage so chains can act on each other's transactions within the same slot, settling on Ethereum.
