🚀🌐 New Ethereum proposal challenges centralized block builders with decentralized BFT & randomization: - Ends block-level MEV by randomizing transaction selection - Shifts power from 2 dominant entities to all clients - Faster blocks (6-8s) but trades some rollup efficiency ⚖️ Three key takeaways: ✓ 80% of blocks now controlled by two entities under PBS ✓ All clients propose blocks via shared randomness + BFT consensus ✓ Trade-offs: Trustlessness > optimization, mempool sync risks
