ADVANCED
Build on Polkadot's multi-chain ecosystem — master the relay chain/parachain architecture, shared security, Substrate runtime development with FRAME pallets, XCM cross-chain messaging, ink! smart contracts, and OpenGov.
The relay chain, parachain model, shared security, and how Polkadot differs from other multi-chain ecosystems.
Build custom blockchains with Substrate's FRAME framework — pallets, storage, dispatchable calls, events, and runtime upgrades.
Cross-Consensus Messaging — XCM's virtual machine model, XCMP transport layer, reserve-backed transfers, and building XCM programs.
Write, test, and deploy Substrate-native smart contracts with ink! — Rust-based, Wasm-compiled, with full access to the contract pallet.
Coretime markets, crowdloans, the Polkadot Treasury, and OpenGov's multi-track referendum system.
Design a complete Substrate-based parachain for a real-world use case.
