Applications build with Ethereum do not cover all use cases of course, but have specific properties that make them unique: 1  Ethereum applications always execute the code they say they will - there is no 'security through obscurity'. I don't need to 'trust' anything or anyone, because I can check the app code myself. Ethereum applications are always available, and are guaranteed to be available in the future. There is no downtime.
A transatlantic telegraph cable is an undersea cable running under the Atlantic Ocean used for telegraph communications. The first was laid across the floor of the Atlantic from Telegraph Field, Foilhommerum Bay, Valentia Island in western Ireland to Heart's Content in eastern Newfoundland.efore the first transatlantic cable, communications between Europe and the Americas took place only by ship. Sometimes, however, severe winter storms delayed ships for weeks. The transatlantic cable reduced communication time considerably, allowing a message and a response in the same day.
The Transatlantic Cable Until the first transatlantic cable was laid, the fastest communication between Europe and North America took at least a week.he first major undersea link, connecting England to France, was not completed until 1851 after several failed attempts. The idea of a transatlantic cable was first proposed in 1845, only a year after the first practical demonstration, but the far greater distances and greater depths presented formidable problems.
