Teave: Cardano
Cardano on detsentraliseeritud platvorm, mis lubab keeruka programmeeritava väärtuse ülekandeid turvaliselt ja mastaapsemalt. Ada on krüptoraha, mis on Cardano platvormi sisse ehitatud ja toimib platvormisisese väärtusühikuna. Daedalus on krüptovaluuta rahakott, kus saab ada-t hoiustada.
Cardano platvormi on loonud plokiahela arendusfirma Input Output Hong Kong ja seda juhib Charles Hoskinson, kes on BitSharesi ja Etherumi kaasasutaja. Cardano tuli välja 29. septembril 2017.
Ada krüptomündid on kaevandatavad ja kõik tehingud tehakse Ouroborose proof-of-stake'i algoritmi põhjal. Sellise protokolli puhul genereeritakse uusi münte ja kinnitatakse tehinguid kasutajate poolt, kes omavad ada münti. Sellist kasutajat nimetatakse slot leader'ks. Slot leader'i valimine on iga kord nagu loterii – igaüks võib võita, kes omab ada münti. Tänu sellele tehnoloogiale säästetakse palju energiat sellega, et ei pea kulutama nii palju arvutusvõimsust komplekssete matemaatiliste probleemide lahendamisele. WikipediaTeave: USA dollar
The United States dollar is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color.
The U.S. dollar was originally defined under a bimetallic standard of 371.25 grains fine silver or, from 1834, 23.22 grains fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, its equivalence to gold was revised to $35 per troy ounce. In 1971 all links to gold were repealed. The U.S. dollar became an important international reserve currency after the First World War, and displaced the pound sterling as the world's primary reserve currency by the Bretton Woods Agreement towards the end of the Second World War. The dollar is the most widely used currency in international transactions, and a free-floating currency. Wikipedia
