Crypto

Overview

Crypto assets are digital database systems based on cryptography and blockchain technology. In most cases, crypto assets are used as payment tokens in the financial context and thus represent digital money issued by unregulated private parties. Today, the most relevant crypto assets are Bitcoin and Ether. In contrast to bank transfers, transactions of crypto assets do not require intermediaries such as banks.

Ethereum Whitepaper

Whitepaper

This introductory paper was originally published in 2013 by Vitalik Buterin, the founder of Ethereum, before the project's launch in 2015. It's worth noting that Ethereum, like many community-driven, open-source software projects, has evolved since its initial inception.

While several years old, we maintain this paper because it continues to serve as a useful reference and an accurate representation of Ethereum and its vision.

Bitcoin: A Peer-to-Peer Electronic Cash System

Whitepaper

A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures  provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work. The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power. As long as a majority of CPU power is controlled by nodes that are not cooperating to attack the network, they'll generate the longest chain and outpace attackers. The network itself requires minimal structure. Messages are broadcast on a best effort basis, and nodes can leave and rejoin the network at will, accepting the longest proof-of-work chain as proof of what happened while they were gone.

Überblick

Kryptowerte bezeichnen auf Kryptographie und der Blockchain-Technologie basierte digitale Systeme. Zumeist werden Kryptowerte im Finanz-Kontext als Zahlungsmittel (Payment Token) eingesetzt und stehen folglich für ein vom Privatsektor emittiertes digitales Geld. Die derzeit bekanntesten Kryptowerte sind Bitcoin und Ether. Im Gegensatz zu Transaktionen per Banküberweisung wird bei Transaktionen mit Kryptowerten kein Intermediär, wie bspw. eine Bank, benötigt.

Wie funktioniert Bitcoin?

Medium

Satoshi Nakamoto setzte 2008 mit der Einführung von Bitcoin eine Revolution in Gange. Bitcoin stellte das erste auf einer Distributed-Ledger-Technologie (DLT) basierte digitale Geld dar. Im Gegensatz zum klassischen Finanzsystem sind für Bitcoin-Transaktionen keine Intermediäre, wie Banken oder Zentralbanken, notwendig, die eine Transaktion bestätigen müssen. Bitcoin ist als Vorreiter für zahlreiche DLT-Initiativen zu sehen, sodass aktuell mehr als 5.000 DLT-basierte Kryptowerte existieren. Ein Grund, weshalb Bitcoin noch nicht weiter verbreitet ist, liegt häufig auch am unzureichenden technologischen Verständnis der fairerweise nicht ganz einfach zu verstehenden DLT. Dieser Beitrag zielt darauf ab, das Bitcoin-System und die dahintersteckende DLT zu erläutern und somit Bitcoin auch dem Leser ohne technologisches Hintergrundwissen näher zu bringen.
