Polkadot is a blockchain platform that isn't like most blockchain platforms. It's designed to support a wide range of use cases, from financial transactions to distributed applications and even private data storage. It allows users to create their own blockchains, which can be customized in a variety of ways.

Polkadot

Cardano is a blockchain platform that, in some ways, aims to improve on the design of the original blockchain. Cardano is an open source project that features a smart contract system as well as a new proof-of-stake algorithm. What makes Cardano unique from other blockchain platforms is their philosophy of engineering decisions toward a "philosophy of simplicity". The goal of this philosophy is to eventually reduce the total number of ways to interact with the chain to three: (1) stake, (2) spend and (3) vote.
