The curious case of the missing Mt. Gox bitcoin fortune
We investigate how distributed denial-of-service DDoS attacks and other disruptions affect the Bitcoin ecosystem. In particular, we investigate the impact of shocks on trading activity at the leading Mt. Gox exchange between April and November We find that following DDoS attacks on Mt. Gox, the number of large trades on the exchange fell sharply. In particular, the distribution of the daily trading volume becomes less skewed fewer big trades and had smaller kurtosis on days following DDoS attacks.
The results are robust to alternative specifications, as well as to restricting the data to activity prior to March , i. The recent rise in digital currencies, led by the introduction of Bitcoin in [ 1 ], creates an opportunity to measure information security risk in a way that has often not been possible in other contexts.
They have been designed with transparency in mind, which creates an opportunity to quantify risks better. In this article, we investigate how one such risk, distributed denial-of-service DDoS attack, affects the Bitcoin ecosystem. While denial-of-service attacks have been launched on a wide range of Bitcoin services, from gambling sites to mining pools [ 2 , 3 ], we focus our investigation on how DDoS attacks affected the Mt.
Gox exchange. We do so for several reasons. First, prior research has established that Mt. Gox has been targeted by DDoS attacks far more than any other Bitcoin service [ 2 ]. Second, DDoS attacks on currency exchanges have the potential to be financially lucrative to its proponents as well as extremely disruptive: preventing others from buying or selling creates an unfair financial advantage for the perpetrator at the expense of ordinary participants.
Third, following Mt. Finally, as Fig. Gox was by far the leading Bitcoin exchange during most of the 2. Distribution of market share among Bitcoin currency exchanges by reported trade volume, April to November Source : bitcoincharts.
While we cannot know for certain what has motivated the spate of DDoS attacks on Bitcoin currency exchanges, there are several plausible explanations for why someone might do so. First, there is considerable competition among currency exchanges, along with high turnover in terms of which platforms dominate.
Figure 1 shows evidence of this: while Mt. Gox was the dominant exchange in , a series of four new entrants emerged in and to overtake Mt. While one cannot conclude that the 34 reported DDoS attacks on Mt. Gox caused it to shed market share to new entrants, it remains a distinct possibility since frequent service interruptions might drive wary customers to alternative platforms.
While there is no evidence that the new entrants were behind the DDoS attacks on Mt. Gox, they certainly would have stood to gain from doing so. The lawless nature of Bitcoin during this period, combined with scores of new exchanges fighting for market share, might have led one or more of the smaller exchanges to target their biggest rival. Second, profit-motivated traders might also launch DDoS attacks to create favorable trading conditions.
This could happen both when prices rise and fall. As prices rise, DDoS attacks could slow that rise by preventing traders who want to buy from being able to do so. For instance, a trader who is trying to buy bitcoin on its way up might put in a large order at a smaller exchange while blocking access to the larger Mt.
His lower bid might be accepted by sellers who temporarily cannot sell on the larger platform. Alternatively, if the attacker holds bitcoin, he might be able to ask for a higher price on a smaller exchange when buyers are blocked from participating on Mt. As prices fall, DDoS attacks might slow a decrease by limiting the completion of sell orders that drive the price downwards. An attacker who holds bitcoin but is concerned that its value may fall could be tempted to launch a DDoS attack.
It is worth noting that even if these attacks do not have the intended effect of artificially raising or lowering prices as the perpetrators intend, they still could be launched in expectation that they could work.
The low cost of launching DDoS attacks combined with a very low likelihood of being caught could drive miscreants to experiment with strategies regardless of whether or not they actually succeed in making money.
Using an event study design, we find that following DDoS attacks on Mt. Gox, there was a significant reduction in the number of large trades on the exchange. In particular, the distribution of the daily trading volume becomes less skewed fewer big trades on days following DDoS attacks. The results are robust to alternative specifications and to restricting the data to the period March , i. The question is important because exchanges are critical institutions in the Bitcoin ecosystem.
In the exchanges, sellers benefit from a larger number of buyers, and buyers benefit from a larger number of sellers so-called positive cross-side network effects. An exchange is an example of a platform; in order for an exchange to succeed, it must build up trust among its users, since a loss of confidence in an exchange can quickly lead to a downwards spiral in which buyers and sellers quickly cease trading on the platform.
The market for cryptocurrency exchanges is very vibrant. The exchanges considered to be the major players changed significantly over time. New ones appeared, and existing ones were pushed out of the market. The Mt. Gox failure in February showed that even a large exchange may suddenly exit the market. The popularity of Bitcoin, especially when compared to prior cryptocurrencies, has spawned a huge amount of research activity.
Bonneau et al. Taken together, these articles offer a baseline understanding of key issues facing cryptocurrencies identified by scholars. Some have mined the blockchain, the public ledger of completed transactions. Meiklejohn et al. Ron and Shamir constructed a graph of Bitcoin transactions from the blockchain to identify suspicious transaction chains [ 7 ]. Currency exchanges have been recognized to play a central role in the Bitcoin ecosystem. Vasek et al.
People could deliberately introduce shocks to Bitcoin exchanges to profit financially e. A denial-of-service attack might introduce enough instability for a malevolent actor to exploit.
We hope to explore this issue in future work. In this article, we conduct the first econometric study of the impact of denial-of-service attacks on trading activity at Bitcoin exchanges.
We first describe the data sources used, then explain how the regression model is designed. We collected two principal types of data: on exchange activity and shock events. Shortly after filing for bankruptcy in early , a trade history of Mt. Gox transactions was publicly leaked. These data offer much finer granularity than is typically available, since most buy and sell transactions are recorded only by the exchange and never appear on the blockchain.
The data can be leveraged to monitor changes in user participation as well as overall transaction volume at times surrounding shocks. In total, nearly 18 million matching buy and sell transactions are reported between April and November We supplemented these data with daily transaction volumes reported by the bitcoincharts. Because some entries obtained from bitcoincharts. While it is impossible to directly ascertain the validity of the Mt. Gox transaction data, we did conduct a few sanity checks to ensure that the data are consistent.
As a first check, we verified that the total buy transactions are matched in number and aggregate value for the sell transactions. Upon delving deeper into the Mt. Gox leaked data, we identified that there are many duplicate entries in the dump file. We have found that the Mt. We considered two forms of de-duplication. The more conservative approach is to treat each user ID, timestamp, transaction type, amount in BTC, amount in Japanese Yen tuple as unique de-duplication strategy 1.
Note that each completed transaction has both a buy and sell record, which means that the total number of unique completed transactions is 7 million. Using this strategy, transactions that are reported at the same time but at different exchange rates are treated as duplicates.
As a further sanity check, we compared the de-duplicated data with other data reported by others. To that end, we compared the Mt. Gox transaction volumes to the daily totals reported on bitcoincharts.
Both de-duplicated datasets are more consistent with the daily totals found on bitcoincharts. Figure 2 plots the daily differences in transaction between leaked dataset and totals reported by bitcoincharts. Differences are normalized as a fraction of the leaked daily volume. Positive numbers indicate that the leaked data reported higher volume.
Note that some difference is expected, particularly if the time zones used in the leaked data and on bitcoincharts. Also, note that there were a few gaps in when data were reported by bitcoincharts. These gaps only affect the comparisons between datasets, not the subsequent analysis. Daily differences in transaction volume between leaked dataset and totals reported by bitcoincharts. Overlaid on the graph is a red dotted line on days where DDoS attacks are reported at Mt.
Gox, and a blue dashed line for other shocks. From this we can see that data are available during the shocks, and there does not appear to be any increase in the disparity between sources on days where shocks occurred. The top graph reports on de-duplication strategy 1. We can see that the transaction volume is always the same or higher in the leaked data. The difference, while volatile, increases somewhat as time passes.
