Euro
The euro (sign: €; code: EUR) is the official currency of 19 of 27 member states of the European Union, as well as some of the territories of the EU. This group of states is known as the eurozone or euro area. It is the second largest and second most traded currency in the foreign exchange market after the United States dollar . The euro is subdivided into 100 cents. The currency is also officially used by the institutions of the European Union and its territories, four other European countries, as well as unilaterally by two others, and is consequently used daily by some 343 million Europeans (As of 2018). Outside Europe, a number of overseas territories of EU members also use the euro as their currency. Additionally, 240 million people worldwide (As of 2018) use currencies pegged to the euro. The euro is the second largest reserve currency as well as the second most traded currency in the world after the United States dollar. (As of August 2018), with more than €1.2 trillion in circulation, the euro has one of the highest combined values of banknotes and coins in circulation in the world, having surpassed the U.S. dollar.[note 14] The name euro was officially adopted on 16 December 1995 in Madrid. The euro was introduced to world financial markets as an accounting currency on 1 January 1999, replacing the former European Currency Unit (ECU) at a ratio of 1:1 (US$1.1743). Physical euro coins and banknotes entered into circulation on 1 January 2002, making it the day-to-day operating currency of its original members, and by May 2002 it had completely replaced the former currencies. While the euro dropped subsequently to US$0.83 within two years (26 October 2000), it has traded above the U.S. dollar since the end of 2002, peaking at US$1.60 on 18 July 2008. In late 2009, the euro became immersed in the European sovereign-debt crisis, which led to the creation of the European Financial Stability Facility as well as other reforms aimed at stabilising and strengthing the currency.

Productivity Improving Technologies
The productivity improving technologies are the technological innovations that have historically increased productivity. Productivity is often measured as the ratio of (aggregate) output to (aggregate) input in the production of goods and services. Productivity is increased by lowering the amount of labor, capital, energy or materials that go into producing any given amount of economic goods and services. Increases in productivity are largely responsible for the increase in per capita living standards.

Agorism is a libertarian social philosophy that advocates creating a society in which all relations between people are voluntary exchanges by means of counter-economics, thus engaging with aspects of peaceful revolution. It was first proposed by libertarian philosopher Samuel Edward Konkin III at two conferences, CounterCon I in October 1974 and CounterCon II in May 1975, both conferences organized by J. Neil Schulman.

Let's Encrypt
Let's Encrypt is a certificate authority that provides X.509 certificates for Transport Layer Security (TLS) encryption at no charge. The certificate is valid for 90 days, during which renewal can take place at anytime. The offer is accompanied by an automated process designed to overcome manual creation, validation, signing, installation, and renewal of certificates for secure websites. It launched on April 12, 2016. The project claims to make encrypted connections to World Wide Web servers ubiquitous. By eliminating payment, web server configuration, validation email management and certificate renewal tasks, it is meant to significantly lower the complexity of setting up and maintaining TLS encryption. On a Linux web server, execution of only two commands is sufficient to set up HTTPS encryption and acquire and install certificates. To that end, a software package was included into the official Debian and Ubuntu software repositories. Current initiatives of major browser developers such as Mozilla and Google to deprecate unencrypted HTTP are counting on the availability of Let's Encrypt. The project is acknowledged to have the potential to accomplish encrypted connections as the default case for the entire web. Only domain-validated certificates are being issued, since they can be fully automated. Organization Validation and Extended Validation Certificates are not available. By being as transparent as possible, they hope to both protect their own trustworthiness and guard against attacks and manipulation attempts. For that purpose they regularly publish transparency reports, publicly log all ACME transactions (e.g. by using Certificate Transparency), and use open standards and free software as much as possible. Support of ACME v2 and wildcard certificates was added in March 2018.
