Present-day blockchain architectures suffer from several problems, including poor extensibility and scalability. This may stem from tying two parts of the consensus architecture, namely canonicality and validity, too closely together. The Polkadot architecture, which is a heterogeneous multi-chain, provides better extensibility and scalability by setting canonicality and validity apart. Compartmentalizing canonicality and validity and keeping overall functionality to a minimum of security and transport introduces practical core extensibility in situ. Scalability is addressed through a divide-and-conquer approach to canonicality and validity, scaling out of its bonded core through the incentivization of untrusted public nodes. The heterogeneity of this architecture enables many highly divergent types of consensus systems interoperating in a trustless, fully decentralized “federation,” allowing open and closed networks to have trust-free access to each other. This architecture is compatible with pre-existing networks, including Ethereum, and a useful component in a practical system for global-commerce scalability and privacy.
