Cardano (patter Pennant)
PENNANT — A Pennant is a Flag with converging, rather than parallel,
boundary lines.
Cardano (ticker symbol, ADA) is a decentralized proof of stake (PoS) blockchain designed to be a more efficient alternative to proof of work (PoW) networks.
Cardano's cryptocurrency is named Ada after Augusta Ada King, Countess of Lovelace (1815-1852), who is commonly regarded as the first computer programmer. Ada is used in the blockchain's PoS consensus mechanism. It is given as a reward for work done for the blockchain by users participating in a stake pool.
