What is Polkadot?
Polkadot is a blockchain protocol designed to support multiple chains within a single network. It aims to overcome a problem in the current blockchain landscape: hundreds of blockchains exist in isolation and have little ability to communicate.
People find value in DOT because it promises to provide significant interoperability between a number of blockchains, while also highlighting the benefits of sharding. Despite the Polkadot project being worked on for years, it was just launched and still has a long way to go to catch up with a number of cross-chain competitors.
What are the use cases of DOT?
