Base’s Flashblocks, Politicizing Crypto, and L1 Revenue Streams | Roundup

In this week's roundup, the crew discusses Base’s Flashbocks, and the pushback they received regarding centralization concerns. They also dive into their concerns with the rapid politicization of crypto. Finally, they cover the economic models of blockchains, particularly general-purpose L1s versus L2s. Enjoy! – L2s and L3s are history. Supra Containers give you dedicated, customizable AppSpace on Supra’s Layer-1 to rescue you from the costs, complexities, and fragmentation of L2s and L3s.  Containers help you build with better customization and control than appchains at a fraction of the cost. Use your own token as the gas token, create local fee markets with custom gas amounts or just go gasless, and scale on demand whenever you need to. Supra Containers are secured by Supra’s L1 nodes and get access to Supra’s 500k TPS throughput, sub-second consensus latency, and all their built-in services like oracle price feeds and onchain randomness without any overhead. Supra is also MultiVM compatible so you can easily deploy your EVM, Move, and SVM smart contracts here. Get all the freedom, control, and tools you need to build super dApps and bring the world onchain.
