一文报你知:以太币夯什么
和比特币哪里不同?
950点看 2017年6月23日
 

(北京23日讯)今年至今以太币价格大涨3000%,涨幅远胜比特币的180%,到底以太币在红什么?


以太币受瞩目,主要是背后的以太坊(Ethereum)技术潜力无穷,能创造出国际共享的“全球电脑”(world computer),有望打造出更好的网路世界。

Mic、Motherboard报道,比特币和以太币都是基于区块炼发展出来的虚拟货币。虚拟货币和区块炼是不同的东西,区块炼有如公开帐簿,让各地人们都能看到未经删节的交易纪录。

虚拟货币则是可编程的数位金钱,中本聪研发出比特币区块炼,方便全球民众无须透过第三方认证,就能相互传送比特币使用。比特币区块炼专为比特币服务,用途较窄。

许多人发现区块炼潜力不只如此,Vitalik Buterin 19岁时开发出以太坊(Ethereum)区块炼,可用于智慧合约(smart contract)。使用以太坊技术需要付费,以太币(ether)是用来付款的代币。也就是说,以太币是为了服务以太坊而存在,两者关系与比特币恰恰相反。

以太坊用途超越虚拟货币,是去中央化应用程式的平台,能执行智慧合约。智慧合约是种程式码,某种条件满足后,就会自动执行,比方说,过了某个日期之后,把部分应用程式利润转给投资人等。简单来说,以太坊有如全球共享的电脑,大家能交换讯息、数据、资讯,无须担心遭骇或操弄。如此一来,网路不再需要由上而下管理,转而进入去中央化的联网时代。

以太坊已有许多实际应用,联合国世界粮食计划署(World Food Program)利用以太坊技术,纪录协助一万名叙利亚难民。丰田汽车(Toyota)也用以太坊技术,搜集分享无人车资讯。由于以太坊用途广,各方看好,带动以太币价格暴冲。

CNBC和equities.com 2015年12月报道,区块炼被视为金融科技(FinTech)的颠覆性科技,区块炼能清楚纪录每一笔交易、不会遭骇,比特币只是这个技术的“暖场秀”而已。简单来说,区块炼是公开透明的交易纪录方式,没有中央管理系统,每个端点都可储存交易资料,结合各端点数据后,能创造出具有明确时间点的完整交易纪录,由于资料持续在数千个端点分享,能及早发现不完整的数据,避免写入。

这么做的好处是,要是有哪个端点的操作者想伪造资料,其他端点若不加以确认,就无法记入正式数据当中。传统的集中管理系统,不管有多严格的防护措施,都可能遭骇,区块炼等于让帐簿正本不复存在,骇客无处下手,他们可以改动一两处数据,但不可能变更所有端点的资料。从比特币历史看来,这个技术确实能够防骇。

高盛和巴克莱认为,此一技术可用于银行转帐交易、证券交易等。那斯达克证交所和高盛都打造了运用区块炼的交易平台。不仅如此,区块炼还能用于投票、汽车牌照登记、枪枝管制、贸易收支、纪录艺术品所有人等。

The price of ethereum crashed as low as 10 cents from around $319 in about a second on the GDAX cryptocurrency exchange on Wednesday, a move that is being blamed on a "multimillion dollar market sell" order.

Ethereum is an alternative digital currency to bitcoin and had been trading as high as $352 on Wednesday. It has since rebounded from its flash-crash lows to trade to about $325 on the GDAX exchange. According to industry and price tracking website Coinmarketcap, which takes into account the price on several exchanges, ethereum was trading around $338.

Adam White, the vice president of GDAX which is run by U.S. firm Coinbase, posted on the exchange's blog, outlining what took place at around 12:30 p.m. PT on Wednesday. According to White, the multimillion dollar market sell order resulted in a number of orders being filled from $317.81 to $224.48.

As the price continued to fall, another 800 stop loss orders and margin funding liquidations caused ethereum to trade as low as 10 cents.

A stop loss order is a trade that is executed automatically once a security — in this case ethereum — hits a particular price. Margin funding is essentially trading with borrowed funds. Liquidation is when these positions are closed automatically in order to prevent further losses. The knock-on selling effect caused the flash crash on GDAX.

The chart below is a screenshot of the GDAX price showing the high and low price.


GDAX
Many on social media criticized GDAX and alleged there was some sort of illegal activity taking place. GDAX denied this.

"Our initial investigations show no indication of wrongdoing or account takeovers. We understand this event can be frustrating for our customers. Our matching engine operated as intended throughout this event and trading with advanced features like margin always carries inherent risk," White said in a blog post.

"We are continuing to conduct a thorough investigation and will keep customers updated with any resulting actions."

White also noted that these trades are final and will not be reversed. The exchange temporarily halted trading of ethereum on Wednesday before restoring the system shortly after.

As well as the issues on GDAX, investor demand at the funding launch for an ethereum-based messaging app called Status clogged the ethereum network, an industry insider told CNBC.

Ethereum traders were outraged by the crash blaming GDAX for not having proper controls, and even accusing whoever put the sell order in of market manipulation.
