Substrate: A Rustic Vision for Polkadot
summary
Claims a full blockchain can be coded and deployed in minutes, demonstrates a live coding demo that adds a WASM runtime module (a coin‑flip game), wires it into the runtime, and upgrades the chain on‑chain with a hot runtime upgrade (no hard fork). Shows SRML modules (balances, governance, assets), pluggable consensus, libp2p networking, JS UI and light clients, and explains Polkadot slot leases and parachain governance rather than just promising “examples” or high‑level concepts.
