What Is Lovelace?

0.000001 ADA = Lovelace

ADA has six decimal places and its smallest unit (0.000001 ADA) is called Lovelace.

The name Lovelace is a homage to Ada Lovelace who was a gifted mathematician – also considered to be the first computer programmer. Ada Lovelace was born on December 10, 1815, in London, England. Lovelace met Charles Babbage in 1833. Babbage invented the Difference Engine and the Analytical Engine, two of the first classes of engines. 

In 1843, Babbage asked Lovelace to translate an article about his invention, written by Italian mathematician Luigi Menabrea. Lovelace added extensive notes to her translation, which described how codes could be created for the machine to handle letters and symbols along with numbers. Her notes also included an algorithm for calculating Bernoulli numbers with the machine.

The Cardano coin, ADA, is also named after Ada Lovelace. 

Charles Hoskinson (one of the co-founders of IOHK) chose to name the token ADA in tribute to Ada Lovelace because he believes that she was the first person to recognize that computers weren’t just about calculating but were also capable of efficient functioning, something we now refer to as algorithms.
