圣路易斯联邦储备银行发布了一份研究论文，证实BTC/" target="_blank"">比特币作为一种货币的合法性，即使用作促进私人交易的工具。

该报告由经济学家查尔斯·卡恩（Charles Kahn）撰写，上个月由圣路易斯联邦储备银行出版，研究了私人支付在货币体系中的作用。

比特币是合法的隐私工具

卡恩认为，除了对非法交易的吸引力之外，私人支付在任何货币体系中都具有重要的合法功能，即“防止交易对手或支付系统提供商本身的渎职或疏忽”。

传统上，这种支付利基是用现金填补的，但现金很快被数字支付所取代。卡恩解释说，这并不意味着对私人交易的需求将会消失;相反，他说“用央行电子货币取代现金可能刺激对替代支付方式的需求，以解决特定的隐私问题。”

其中一种替代支付系统是比特币：

“因此，有一个合法的交易隐私市场。比特币就在这个市场上。储值卡的提供者在这个市场中。在某种程度上，PayPal就在这个市场中，信用卡公司也有这样的互联网交易标记化程序。政府提供的货币也在这个市场中。“

但是，虽然PayPal和信用卡处理器等第三方支付提供商可能会向用户提供其交易对手的隐私，但他们会将个人信息暴露给系统本身。然而，比特币没有。

卡恩写道：“比特币的一个很酷的功能是它允许在互联网上进行交易，同时保持比特币系统的隐私。”

公众不会相信政府发布的“数字现金”

圣路易斯联邦储备银行对比特币在美国支付市场获得立足点的态度令人惊讶。

值得注意的是，该报还进一步指出，中央银行不应该试图创建匿名数字现金，因为公众不太可能相信政府会愿意创建一个没有后门的数字货币。

“相信美国中央情报局已经通过一项技术印刷纸币，使其能够报告手拉手交易是偏执狂。相信间谍机构有共同计算机程序的后门是上周的新闻，“卡恩写道。“对公共支付机构的新电子货币的隐私承诺产生信任将是一项非常艰巨的任务。”

虽然几家美联储分支机构对加密货币采取公开敌对立场，但本文标志着圣路易斯联邦储备银行提出的一系列声明中的最新消息，即该银行对比特币作为金融工具的增长持开放态度。

例如，今年早些时候，圣路易斯联邦储备银行发表了一份赞扬匿名加密货币的报告，这是中央银行采取的一个非凡的立场。

此前，该银行发布了一篇博客文章，展示了比特币如何成为“常规货币”，甚至在其经济研究数据库中添加了加密货币价格跟踪器。

Bitcoin is Cool: St. Louis Federal Reserve

The Federal Reserve Bank of St. Louis has published another research paper validating bitcoin’s legitimacy as a currency, even when used as a tool to facilitate private transactions.

Thereport, which was written by economist Charles Kahn and published by the St. Louis Fed last month, examines the role of private payments in monetary systems.

Bitcoin a Legitimate Privacy Tool

Kahn argues that, beyond their attractiveness for illegal transactions, private payments serve important, legitimate functions in any monetary system, namely, “protection from malfeasance or negligence by counterparties or by the payments system provider itself.”

Traditionally, this payments niche was filled by cash, but cash is quickly being replaced by digital payments This, Kahn explains, does not mean that demand for private transactions will disappear; rather, he says that “the replacement of cash by central bank electronic money is likely to spur demand for alternative means of payments to solve specific privacy problems.”

One of those alternative payment systems is bitcoin:

“Thus there is a legitimate market for privacy of transactions. Bitcoin is in this market. The providers of stored value cards are in this market. To a certain extent, PayPal is in this market, as are the credit card companies with their tokenization programs for internet transactions. And government-provided currency is also in this market.”

But while third-party payment providers such as PayPal and credit card processors may provide users with privacy from their counterparties, they expose personal information to the system itself. Bitcoin, however, does not.

Kahn writes:

“One of the cool features of Bitcoin is its ability to permit transactions across the internet while maintaining privacy from the Bitcoin system.”

Public Won’t Trust ‘Digital Cash’ Issued by Govt.

The St. Louis Fed has been surprisingly open to bitcoin gaining a foothold in the U.S. payments market.

Notably, the paper further argues that central banks should not attempt to create anonymous digital cash, as it is unlikely that the public will ever believe that the government would willingly create a digital currency that did not have backdoors.

“To believe that the CIA has imprinted paper currency with a technology enabling it to report hand-to-hand transactions is paranoia. To believe that spy agencies have backdoors to common computer programs is last week’s news,” Kahn wrote. “Generating trust in the privacy promises of a public payments authority’s new electronic money will be an extremely tall order.”

While several Federal Reserve branches have taken openly-hostile stances on cryptocurrency, this paper marks the latest in a series of statements that the St. Louis Fed has made suggesting that the bank is open to bitcoin’s growth as a financial instrument.

Earlier this year, for instance, the St. Louis Fed published a reportpraising anonymous cryptocurrencies, a remarkable stance for a central bank to take.

Previously, the bank published ablog postdemonstrating the ways in which bitcoin is like “regular currency” and even addedcryptocurrency price trackersto its economic research database.
