坡县首个比特币交易官司开打-有人关注么?

Quoine being sued over trade proceeds worth $5.1mSingapore’s first legal dispute involving the cryptocurrency bitcoin has erupted over trade proceeds worth around US$3.78 million (S$5.1 million).

An electronic market maker is suing Quoine, one of the world’s major bitcoin exchange operators, over trades that were allegedly wrongfully reversed, which resulted in proceeds being deducted.

The market maker, B2C2, said it placed orders on Quoine’s platform to sell ethereum – another cryptocurrency – for bitcoin at the price of 10 bitcoins for one ethereum.
The orders were filled in a series of trades on April 19, resulting in B2C2 paying 309.2518 ethereum for 3092.517116 bitcoin. The bitcoin was credited into B2C2’s account that day.

But the next day, the trades were reversed by Quoine, which is incorporated here, and the proceeds allegedly “misappropriated” from the account without authorisation.

Quoine told B2C2 that it was entitled to do so because the trades were “mostly trades with huge mark-up over fair global market price”, the suit said
B2C2 claims Quoine had “acted fraudulently” because the agreement stated that an order, once filled, is “irreversible”. It is seeking to recover 3084.78582325 bitcoin from Quoine in the High Court.
Quoine, a fintech firm that also offers other cryptocurrency-related services, was co-founded by Mr Mike Kayamori, who has held senior roles at Mitsubishi Corp and Softbank Group.

No dollar value for that amount of bitcoin was provided in the lawsuit but according to cryptocurrency exchange CoinDesk, that amount translates to US$3.78 million based on an exchange rate of US$1,226.94 for a bitcoin on April 19.

Quoine in turn claims that B2C2 is “being opportunistic and seeking to profit from a technical glitch”

It said the trades were “inadvertently” executed at the “abnormal rate of... 10 bitcoins for one ethereum, which was approximately 125 times higher than the actual market price of ethereum on April 19” because of a technical glitch.

It said the average market price that day was only about 0.03929075 bitcoin for one ethereum
The glitch severely disrupted Quoine’s ability to retrieve actual market prices for bitcoin and ethereum. It said the glitch arose because it was reconfiguring passwords for its critical systems to fend off persistent attempts by hackers to break into its systems.

Given the “stark difference between the abnormal rate and the actual market prices of bitcoin and ethereum on April 19”, B2C2, which Quoine called a “sophisticated” investor with experience trading virtual currencies, should have suspected the “abnormal rate” was a mistake. It also noted B2C2 had done other bitcoin and ethereum-related trades on Quoine at prevailing market rates between April 15 and 18.

Public resources such as CoinDesk and WorldCoinIndex would have shown that the abnormal rate could not be an accurate reflection of the market prices of these two virtual currencies on April 19, Quoine said.

既然区块链可以去中心,这种事怎么可能发生?所以,我只转不读,呵呵

这个只是个平常的错盘交易纠纷跟可靠性什么的有毛关系？

去中心的区块链交易怎么会产生错盘?是疑问所在.
区块链界的说法是, 错了就不会有交易, 交易了就不该错

价钱是人放的啊你卖西瓜放错了价钱不能赖西瓜。西瓜也不知道自己值多少钱啊。

放错了价钱，通过区块链认证是有效交易啊，难道区块链允许事后修改？除非是在做一个新的交易

这事明显是Quoine耍赖啊B2C2手上有ETH要卖，明码标价童嫂无期的说价格是1个ETH值10个BTC，B2C2放了order在quoine的交易平台上，真有人来买，B2C2卖出去了309个ETH，得到了3090个BTC。

结果第二天，QUOINE，取消了上面的交易。理由是：B2C2卖ETH的价格明显高于市场价，是当天市场价格的125倍。

这简直就是胡扯。有人卖，有人买，明码标价，取消这个交易不对啊。

谁对谁错,不知道,法官定区块链交易,怎么可以取消?强制原价买回?

业内人士说下这个交易成功后的取消是怎么回事，怎么操作的吧？

法律不健全而且不同国家法律不同，因此买家卖家如果所在地区不同打起官司很戏剧的。

比如以中国的法律，假如一个商家在网上卖3000的手机，结果少打了个0，然后买家发现了下单去买，即使交易成功卖家拒绝发货并请中间平台取消交易，基本上都会取消的。买家即使不干，基本上起诉了也是很难赢官司的。

在法律层面上不是这样的错盘事件时有发生。犯错的一方通常有颇大的损失，但也不是说错了活该。一般交易所都有规则在发生了错盘的时候有什么流程。这个bitcoin的交易所应该不是受监管的。官司结果怎样很难说。

我的关注点是技术上这个取消怎么完成的？区块链上怎么记录？如果可以完成，怎么叫去中心？怎么保证记录可靠？
