" summary

Polkadot presents a WebAssembly-based meta-protocol under a mutating relay-layer that runs opinionated parachains and pay-as-you-go parathreads; lease slots win via retroactive “candle auctions.” Crowd loans lock DOTs on-chain (not transferred) for parachain leases. Governance votes auto-enact protocol changes to avoid hard forks. Security relies on extensive external audits, multi-implementation clients and a 1,000-validator push. Cross-chain bridges and asynchronous message passing target scalability and eventual cross-chain composability, with Kusama used as the real-value testbed.
