Februar 2015.*\n+\n+> Zitat von: **iamback** am 16. Februar 2015 um 09:28:38 morgens\n+\n+> Ein nicht PoW-basierter Konsens ist DOA, denn es ist nicht genügend Zeit übrig um die Probleme zu beseitigen, bevor die globale Wirtschaft in 2016 zusammenbrechen wird. Zum Beispiel wurden die eigennützigen Miningattacken jahrelang nicht erkannt (oder sagen wir mal, weitgehend geprüft und anerkannt), nachdem Satoshi PoW vorgestellt hat. Deshalb wird der ernsthafte Markt keinem neurartigen nicht-PoW-Konsens vertrauen. Stattdessen habe ich ein PoW-System kreiert, dass viele der Probleme, die Bitcoin plagen, beseitigt, eingeschlossen der ASICS-Ökonomie. Einige Hinweise sind in meinem obigen verlinkten Post.\n+\n+> Ich habe zudem die mathematische Intuition, dass das Vermeiden der 51%-Attacke immer ein Handel mit der Sicherheit sein wird.\n+\n+In Skycoin spielt die 51%-Attacke keine Rolle. Das Netzwerk könnte 20-mal pro Tag von ihr betroffen sein und es würde sich fast niemand dafür interessieren.\n+\n+Skycoin hat andere mathematische Eigenschaften als Bitcoin und ist unnachsichtiger. Wenn jemand Coins zwischen fünf Leuten hin und her handelt, beeinflusst die 51%-Attacke sie nicht. Man benötigt einen privaten Schlüssel oder jemand in der Transkationskette um Schaden mit einer 51%-Attacke verursachen zu können. Es gibt keine Transaktionsgestaltbarkeit in Skycoin. Fast jeder wird exakt dieselben Ausgaben, Bilanzen und Transaktionschroniken auf der originalen, als auch auf der abgezweigten Chain haben, bis auf den Angreifen und einige Leute, die mit ihm Coins gehandelt haben. Wenn es einen Abzweig (fork) der Chain gibt, kopiert dieser nur die Transaktionen der anderen Chains herüber.\n+\n+Die 51%-Attacke wird nur Leute beeinflussen, die mit zwielichtigen Gestalten und Wettseiten Tageshandel betreiben. Es wird die kommerziellen Transaktionen nicht sonderlich beeinflussen. Wenn ein Exchange anständige Sicherheitsvorkehrungen hat und die Wallets der User abgetrennt aufgewahrt, hat die schlimmste Attacke sehr milde Auswirkungen.\n+\n+Bitcoin hat 100 Millionen Dollar Transaktionsvolumen pro Tag. Absolutes Transaktionsvolumen in Bitcoin ist in etwa 200,000 Bitcoins. Bitcoin hat Transaktionsgestaltbarkeit, was bedeutet, dass wenn jemand eine 51%-Attacke ausführt und die Transaktionen der letzten Stunde zurückdreht, etwa 4 Millionen Dollar und 10,000 Bitcoin in Transaktionensbilanzen verbockt werden. Eine Rücklauf-Attacke, die 24 Stunden zurück geht, könnte 100 Millionen und 200,000 Bitcoins an Schaden verursachen. Ein Angreifer könnte jedwede Transaktion in Bitcoin zurückdrehen.","path":"content/statement/Can Skycoin Be 51 Attacked.de.md","position":29,"original_position":29,"commit_id":"bbc56d248923205a75ddeae268d81c2be118fad9","original_commit_id":"bbc56d248923205a75ddeae268d81c2be118fad9","user":{"login":"AndersNiggelson","id":33003577,"avatar_url":"https://avatars1.githubusercontent.com/u/33003577?v=4","gravatar_id":"","url":"https://api.github.com/users/AndersNiggelson","html_url":"https://github.com/AndersNiggelson","followers_url":"https://api.github.com/users/AndersNiggelson/followers","following_url":"https://api.github.com/users/AndersNiggelson/following{/other_user}","gists_url":"https://api.github.com/users/AndersNiggelson/gists{/gist_id}","starred_url":"https://api.github.com/users/AndersNiggelson/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/AndersNiggelson/subscriptions","organizations_url":"https://api.github.com/users/AndersNiggelson/orgs","repos_url":"https://api.github.com/users/AndersNiggelson/repos","events_url":"https://api.github.com/users/AndersNiggelson/events{/privacy}","received_events_url":"https://api.github.com/users/AndersNiggelson/received_events","type":"User","site_admin":false},"body":"Maybe better: \"Bitcoin verfügt über ein Transaktionsvolumen von 100 Millionen Dollar pro Tag.
