Robert A. Küfner
Robert A. Küfner (15 May 1988) is a German entrepreneur, author and investor. He is mentioned as a pioneer in the field of Bitcoin and blockchain technology. Early life Küfner was born in Wuppertal and raised in Remscheid. He studied Business Administration in Cologne for three terms. Career In 2010, Küfner read an article in '' ''Vice'''' about Bitcoin and saw the potential of the new technology. Fascinated by the possibilities of the blockchain he started mining. He installed a power line in his basement, bought high-performance servers and offered computing power for the mining process, earning many Bitcoins. In 2014, he invested in the Ethereum cryptocurrency. Küfner changed his focus to the technology behind Bitcoin, Distributed Ledger Technology. He met Till Wendler and Florian Reike at a gathering of Bitcoin enthusiasts in Berlin and together they founded nakamo.to in 2017, company for researching and developing DLT. The company was named after Satoshi Nakamoto, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wuppertal
Wuppertal (; "'' Wupper Dale''") is, with a population of approximately 355,000, the seventh-largest city in North Rhine-Westphalia as well as the 17th-largest city of Germany. It was founded in 1929 by the merger of the cities and towns of Elberfeld, Barmen, Ronsdorf, Cronenberg and Vohwinkel, and was initially "Barmen-Elberfeld" before adopting its present name in 1930. It is regarded as the capital and largest city of the Bergisches Land (historically this was Düsseldorf). The city straddles the densely populated banks of the River Wupper, a tributary of the Rhine called ''Wipper'' in its upper course. Wuppertal is located between the Ruhr (Essen) to the north, Düsseldorf to the west, and Cologne to the southwest, and over time has grown together with Solingen, Remscheid and Hagen. The stretching of the city in a long band along the narrow Wupper Valley leads to a spatial impression of Wuppertal being larger than it actually is. The city is known for its s ...

Directed Acyclic Graph
In mathematics, particularly graph theory, and computer science, a directed acyclic graph (DAG) is a directed graph with no directed cycles. That is, it consists of vertices and edges (also called ''arcs''), with each edge directed from one vertex to another, such that following those directions will never form a closed loop. A directed graph is a DAG if and only if it can be topologically ordered, by arranging the vertices as a linear ordering that is consistent with all edge directions. DAGs have numerous scientific and computational applications, ranging from biology (evolution, family trees, epidemiology) to information science (citation networks) to computation (scheduling). Directed acyclic graphs are sometimes instead called acyclic directed graphs or acyclic digraphs. Definitions A graph is formed by vertices and by edges connecting pairs of vertices, where the vertices can be any kind of object that is connected in pairs by edges. In the case of a directed graph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
