Cardano is a public blockchain platform. It is open-source and decentralized, with consensus achieved using proof of stake.
It can facilitate peer-to-peer transactions with its internal cryptocurrency, ADA.

Cardano was founded in 2015 by Ethereum co-founder Charles Hoskinson.
The development of the project is overseen and supervised by the Cardano Foundation based in Zug, Switzerland.
It is the largest cryptocurrency to use a proof-of-stake blockchain,
which is seen as a greener alternative to proof-of-work protocols.

Cloud mining is the process of cryptocurrency mining utilizing a remote datacenter with shared processing power.
This type of cloud mining enables users to mine bitcoins or alternative cryptocurrencies without managing the hardware.
The mining rigs are housed and maintained in a facility owned by mining company and the customer simply needs to register and purchase mining contracts or shares.
Since cloud mining is provided as a service, there is generally some cost and this can result in lower returns for the miner.
