1. 1Scaling Solutions: Layer 2s, Bridges, and Modular ArchitectureHow Ethereum scales without sacrificing decentralization. Rollups, the Dencun upgrade, the major L2 ecosystem, and the modular blockchain stack.6 min
2. 2Modular Blockchain StackA close look at the modular blockchain thesis. Celestia, EigenDA, Avail, restaking economics, rollup-as-a-service, the modular vs monolithic debate, and the rise of app-chains exemplified by dYdX's migration to Cosmos.15 min
3. 3ZK-Proof Primer for UsersA user-facing primer on zero-knowledge proofs: what they actually are, the three properties, the SNARK vs STARK distinction, the ZK-EVM Type 1-4 framework, and where you will encounter ZK in everyday crypto use.20 min
