can create fraudulent transactions for as long as an attacker can overpower the network. November 2008 ein Whitepaper mit dem schlichten Titel "Bitcoin: A Peer-to-Peer Electronic Cash System" veröffentlicht. The verification is reliable as long as honest nodes control the network. An attacker would have to expend a ton of resources to threaten the system, and getting rewarded by coins and transaction fees serve as a deterrent to such fraud. Thus the term blockchain. The possibility of a transactions reversal hangs over everyone. Otherwise an attacker may allocate several IPs in an attempt to hack the network.
Nodes express their acceptance of the block by working on creating the next block in the chain, using the hash of the accepted block as the previous hash. Think of disputes that routinely take place between merchants, consumers and other parties, such as payment processors, PayPal or tax authorities. This makes it difficult for an attacker to execute a fraudulent transaction through a parallel chain. As time progresses, the blockchains record grows and provides assurance to the entire network of its validity. In extrem verdichteter und abstrakter Form beschreibt der Gründer von Bitcoin, wie die Miner mittels des Proof of Work eine praktisch unveränderbare Historie von Transaktionen bilden. Rather, Nakamotos concept of an electronic coin is a chronological series of verified digital signatures. The timestamps are key to preventing double-spending and fraud. Inklusive Grafiken und Quellenangaben. Einfach ist Satoshi Nakamotos Sprache dabei nicht immer.
