The Cardano project began in Tokyo, Japan, with help from a former member of the Ethereum development team.
Because of this, early on it was informally known as “the Japanese Ethereum” by many in the cryptocurrency ecosystem. This reference is no longer being actively used.
Cardano is not a token, it is an independent blockchain which does not rely on any previously existing technology.
It is being implemented from scratch in the Haskell and Rust programming languages.
ADA is the cryptocurrency symbol while Cardano is the name of the overall project.
Total supply of Cardano ADA at the time of this writing: 31.112.483.745 ADA
Maximum total supply: 45.000.000.000 ADA
Daedalus Wallet is the official Cardano full node wallet (which will allow staking once Shelley main net goes live).
Yoroi wallet is also a secure and very popular Cardano wallet that has been gaining more popularity in recent months.
Is Cardano mineable?
Yes, Cardano is “mineable”.
Staking tests began in late 2019. Staking on the mainnet is still not possible at the time of our last review of this text (early 2020).
Once fully decentralized (after the Shelley update), users will be able to stake their ADA coins and earn slot (“block”) rewards.
Staking pools will be made available from within Cardano’s official wallet user interface.
How is Cardano unique?
This is unique in the sense that all these features are built into Cardano since the early project stages, whereas in other cryptocurrencies the compliance and other features are added as plugins or layers built on top of the blockchain later on.
Cardano releases all features as part of a large software ecosystem that is being developed in phases according to a roadmap.
