6.4.14 Polkadot

Polkadot is a next-generation blockchain protocol that unites an entire network of purpose-built blockchains, allowing them to operate seamlessly together at scale. Because Polkadot allows any type of data to be sent between any type of blockchain, it unlocks a wide range of real-world use cases. By bringing together the best features from multiple specialized blockchains, Polkadot paves the way for new decentralized marketplaces to emerge, offering fairer ways to access services through a variety of apps and providers. Polkadot’s design offers several distinct advantages over existing and legacy networks, including heterogeneous sharding, scalability, upgradeability, transparent governance and cross-chain composability.
