荷兰中考现比特币计算题,挖矿从学生抓起?

近日,有关比特币的数学计算题出现在荷兰中考试卷中,试卷上有5道题的题干与比特币有关。据估计,今年大约有20万名荷兰学生参加了这场考试。

根据在美国社交新闻论坛Reddit上流传的试卷,以下大致翻译:

比特币是一种只存在于网络中的数字货币,它诞生于2009年1月1日。比特币是支付方式之一,可以在网上商店和其他在线商家那里购买商品或服务。比特币和一般的货币不一样,它不是由央行发行。所有现存的比特币都是通过电脑算力解决特定的数学问题而产生。它的工作原理如下:每个人都可以在他或她的计算机上通过运行特定软件来参与特定数学问题的计算。计算完成后,电脑主人将收到25枚(新挖掘出的)比特币作为奖励。因为在2014年,每10分钟就有一个数学问题被算出,所以每10分钟就会产生25枚新的比特币。截止到1月1日,世界上大约有1220万枚比特币。

根据上文,请回答以下问题:

1、根据上文,哪一年挖掘出的比特币数量将超过1800万枚?

2、从哪一年开始,计算所获得的奖励将不到一枚比特币?

除此之外,还根据解决上述问题的公式列出了加法计算题。(最终能够被挖掘出来的比特币总数量不会超过2100万枚)

随着荷兰的公共机构对加密货币的认可度越来越高,加密货币也出现在学生们的试卷中。

今年3月份,在一起民事案件中阿姆斯特丹法院裁定,比特币具备财产属性,并得出结论:比特币代表一种价值,是可以转让的。

Mathematics questions pertaining to bitcoin have been included in recent high school matriculation examinations in the Netherlands. Approximately 200,000 Dutch students are estimated to have taken the OVW exam, a mandatory test for students seeking tertiary education in the Netherlands, which included five bitcoin-themed questions.

Dutch High School Examinations Feature Bitcoin-Themed Maths Questions

According to a rough translation of the examination paper circulating on Reddit, students were given the following question introduction:

“Bitcoin is a digital currency that only exists online. It has existed since January 1st, 2009, and can be used as payment method in webstores and for other online services. Bitcoin is not, like standard money, made by a central bank. Instead, all bitcoin that exist are created by having computers participate in solving specific mathematical problems. This works as follows: everyone can run special software on his or her computer that participates in solving such a mathematical problem. The owner of the computer that solves the problem receives 25 (newly created) bitcoin as a reward. Because it was the case that in 2014 such a problem is solved every 10 minutes, 25 new bitcoins were created every 10 minutes. On January 1st, there were (approximately) 12.2 million bitcoin.”

Following from the preceding introduction, students were asked to solve five different mathematical problems. The questions asked that students “calculate in what year the amount of bitcoin exceeded 18 million,” “calculate from which year on the reward will be less than one bitcoin,” “determine the maximal amount of bitcoin that can be in circulation,” in addition to posing addition problems based on the formula used to employed to solve the aforementioned questions.

Netherlands Warming to Cryptocurrency

The test has been offered to students following increasing recognition of cryptocurrency on the part of Holland’s institutions.

During March, the Court of Amsterdam determined that bitcoin possesses “properties of wealth” whilst adjudicating a civil rights case between an individual seeking repayment from an unfulfilled contract pertaining to bitcoin mining. The court concluded that “bitcoin represents a value and is transferable” and “thus shows characteristics of a property right. A claim for payment in Bitcoin is, therefore, to be regarded as a claim that qualifies for verification.”

Earlier this month, the ambassador of the Dutch Blockchain Coalition, Rob van Gijzel, presented a national blockchain research agenda, which had been commissioned by the Dutch Ministry of Economic Affairs and Climate Policy. The ministry had created a designated committee, TopTeam ICT, tasked with analyzing the potential legal, economic, and ethical implications of distributed ledger technology in the Netherlands.
