General Purpose vs App Specific Systems

on YouTube ↗18m

" summary

Argues that neither pure general-purpose chains nor fully bespoke app chains win universally and that domain-specific chains hit the middle ground by reusing EVM tooling while allowing VM and block-parameter tweaks; shows tooling like custom L2 rollups (OP Stack examples, Cairo/Noir, Miden) and a minimal rollup SDK that builds app L2s; surfaces trade-offs—sequencer fees >$10M as a revenue driver, decentralization and silo risks, high infra cost—and frames a decision via three decision questions: tech limits, resource cost, value capture.
