A Scalable Blockchain Platform
summary
Polkadot presents a meta-protocol that scales by running custom blockchains (parachains) attached to a central relay chain that supplies shared security and native message passing; bridges connect out to other chains like Ethereum. Builders use Substrate to compose runtimes in Rust, compile them to WASM, and push live runtime upgrades through on‑chain governance. Nominated proof‑of‑stake lets voting weight trade off tokens for lockup time. Kusama serves as a value‑bearing experimental network for rapid iteration while Polkadot targets stability.
