This is the 3rd episode in our “Fixing Fragmentation” series. In today’s episode, we’re joined by technical co-host and Ethereum researcher, Justin Drake and Polygon co-founder and AggLayer creator, Brendan Farmer. 

Brendan developed a compelling design to increase the safety and efficiency of cross-L2 composability—more robustness and lower gas costs. Polygon has fully embraced Brendan's design and is developing AggLayer to pursue, what it calls, “the aggregated thesis,” a powerful synthesis of the modular and monolithic theses. AggLayer perfectly complements shared sequencing and is a significant step towards the "United of Chains of Ethereum" vision.
