PUFFER JUST PROPOSED A VERTICALLY INTEGRATED STACK TO FIX ETHEREUM ROLLUP FRAGMENTATION. The team is pitching a unified architecture that keeps all layers aligned with L1 - treating them as one integrated system, not separate products. The Puffer Stack has three layers: Trust Layer: pufETH, Puffer Institutional, validators, and restaking form the economic security base. Sequencing Layer: Based sequencing + puffer_preconf preconfirmation service + TEE-based proving deliver fast, accountable transaction ordering. Execution Layer: The Puffer Unifi stack provides dedicated execution environments for apps while remaining Ethereum-aligned. The problem they're solving: Rollup fragmentation around liquidity, composability, sequencing, and user experience. By integrating these layers, Puffer argues they can ease the friction that's been holding back the Ethereum ecosystem. What's next: Detailed specs, test deployments, and app integrations that show how restaking, preconfirmation, and execution work together in practice. ethereum:native ethereum:0x4d1c297d39c5c1277964d0e3f8aa901493664530 ethereum:0x5a98fcbea516cf06857215779fd812ca3bef1b32 ethereum:0xec53bf9167f50cdeb3ae105f56099aaab9061f83
