Polkadot

Polkadot is a heterogeneous multi‑chain technology.

Polkadot is a protocol that allows independent blockchains to exchange information. Polkadot is an inter-chain blockchain protocol which unlike internet messaging protocols (e.g. TCP/IP) also enforces the order and the validitiy of the messages between the chains. This interoperability also allows the additional benefit of scalability by creating a general environment for multiple state machines.
