Puffer Finance has launched a Rollup solution based on Puffer, named Puffer UniFi. The simplified version of the white paper is now online. UniFi uses L1 sorting and integrates pre-confirmation from re-staked validators from Puffer. This allows UniFi to expand from centralized sorters to decentralized networks while maintaining fast, cheap, and reliable transactions.
It solves Ethereum's liquidity fragmentation problem by achieving synchronous composability. Transactions on UniFi can interact directly with other rollup-based protocols without needing cross-chain operations, thereby creating unified liquidity and application layers.
