Modular Structure of Blockchains
summary
Argues that blockchain is just a database and breaks it into three concrete functions: data availability execution consensus. Claims reuse of a heavy consensus layer lets many Layer 2s scale by posting data to L1; rollups are the current production solution, with at least five mainnets supporting rollups. Gives tools and specifics: EVM (Solidity/Vyper), Ethereum has nine precompiles, validiums/volitions for off‑chain data. Reports costs: consensus needs staking or electricity (tens–hundreds of thousands staked), L2 txs fall from ~$5–$10 to ~$0.10–$1, with security traded off for throughput.
