Polkadot is an upcoming multi-chain framework platform, similar to Cosmos, designed to facilitate interoperability and scalability of blockchains that can plug into its ‘Relay Chain.’ Polkadot is an ambitious project that leverages a form of proof-of-stake (PoS) consensus for the broader ecosystem of blockchains that are connected to it and is scheduled for official launch in 2020.
Importantly, Polkadot allows data structures outside of solely blockchains to connect to the network as ‘parachains.’ Originally conceived by Gavin Wood creator of the Solidity programming language, Polkadot is a heterogeneous multi-chain framework where parachains operate through a trust-minimized federation structure.
The scalability problems of blockchain networks are well documented, and platforms like Polkadot are striving to become the next generation of networks that foster enhanced scalability and interoperability through expanding the design concepts of public blockchains and standardizing the transfer of data.
