    Ich kapiere nicht, warum ZBs solche Technik nicht autark einsetzen können. Kommt das noch? Zumindest zwischen BRD und DDR gab es einen Swap, also eine direkte Verbuchung.
    Weils billiger, schneller und sicherer ist.

    Bitcoin (BTC) hashrate reaches 6-month high

    An increasing hashrate suggests that miners are adding more mining hardware and using more power to mine in order to gain more block rewards (rewards miners gain for finding a block) in bitcoin (BTC). Today, bitcoin mining is a capital intensive venture with high electricity costs. It is also assumed that miners participate in bitcoin mining for profits.

    It is important to note that the reward for finding a block is fixed (currently 12.5 BTC). Since the block rewards received by miners are in BTC, mining will be profitable if the value of the block rewards (bitcoin) is higher than the costs of mining.

    Consequently, the addition of mining power on the Bitcoin network can be interpreted as miner’s confidence in the likelihood of a bitcoin price increase.

    Die Technik könnten ZBs doch adaptieren. Blockchain fällt unter keine Geheimnisse. Wenn Institutionen unter sich Infrastruktur dritter nutzten, werde ich misstrauisch.

    Und wie stellst Du Dir das vor? Wenn sich die Deutsche Bank ihre eigene "Blockchain" in den Keller stellt nennt sich das Datenbank. Ich nehme mal an genau so machen die das ja seit Jahrzehnten.

    Sicher in der einfachsten Version, doch Blockchain erlaubt mehr: Datenbank und Datenaustausch samt Dokumentation. Eine Datenbank dürfte jede Bank wie ihren Augapfel hüten, jede Buchung intern doppelt absichern, was bei Blockchain dialogisch geschieht, als fälschungssicher gepriesen wird, dem wohl keine Bank bisher so recht traut. Da schicken alle lieber die Kryptos vor, die zeigen sollen, wie sie sich hacken und plündern lassen. Sobald das geklärt und abgesichert ist, sind die Kryptos weg.

    Majority of bitcoin trading is a hoax, new study finds

    Ninety-five percent of spot bitcoin trading volume is faked by unregulated exchanges, according to a study from Bitwise this week.
    The firm analyzed the top 81 crypto exchanges by volume on industry site CoinMarketCap.com. They report an aggregated $6 billion in average daily bitcoin volume. The study finds that only $273 million of that is legitimate.
    “People looked at cryptocurrency and said this market is a mess; that’s because they were looking at data that was manipulated,” says Matthew Hougan, global head of research at Bitwise.

    ...

    The analysis showed that “substantially all of the volume” reported on 71 out of the 81 exchanges was wash trading, a term that describes a person simultaneously selling and buying the same stock, or bitcoin in this case, to create the appearance of activity in the market. In other words, it’s not real.

    Bitcoin Whale Moves $230 Million for Only 57¢, Actually Overpaid

    Thanks to the transparent and public ledger used by the Bitcoin network, the mysterious and quiet Bitcoin whale thought by some to be the user “Loaded” on the bitcointalk.org forum has been sighted once more moving large sums of Bitcoin worth some USD 230 million for an incredibly small transaction fee of 57 cents… and he actually still overpaid.

    Specifically, BTC 40,000 was transferred, with the transaction containing a miner’s fee of only BTC 0.0001 (10,000 satoshi). With the transaction and address using the “Segregated Witness” protocol, space for data is used more efficiently, resulting in a leaner size of transaction, and therefore, lower fees.

    What is fascinating is that the 57 cent fee was allegedly more than what would have been enough. Bitcoin consultancy Bit Consultants has suggested most Bitcoin users are overpaying for their transaction fees. Its data shows that most transactions pay over three times what is the recommended “fastest and cheapest” fee.

    Bitcoin fees are typically based on how much they are per byte of data, the higher the satoshi per byte, the more likely it is for miners to pick the transaction up to be included in the next block. This is how Bitcoin transactions are confirmed.

    This mega transaction is the latest public advertisement for how cheap it can be to send large amounts of funds over the Bitcoin network. In comparison, a bank or remittance service could charge at least 0.1% but as high as 1%.

    The hackers used a “variety of techniques” including phishing and viruses to obtain a large amount of user data
    Wie schon einmal erwaehnt: wenn man zu dumm ist und dateien oeffnet, die aus irgendwelchen quellen stammen - und sich damit einen virus einfaengt - und noch dazu keine 2FA nutzt, hat man sichs redlich verdient beklaut zu werden.

    The company will use its Secure Asset Fund for Users, an emergency insurance fund, to cover the incident in full and no user funds will be affected, it said.
    Die Excange steht dafuer gerade, zahlt diese Bitcoin zurueck. Allerdings verteuert dies wiederum den handel, da der insurance fund von den usern finanziert werden muss.

    Bei deribit.com ist das uebrigens das gleiche - die haben ebensalls einen insurance fund.
