  • Jana Vembunarayanan Lin Yang Stones Used As Money in the Yap Island
    Money Jana Vembunarayanan Lin Yang Stones used as money in the Yap Island Rai stones were used as money in Yap island, today a part of the Federated States of Micronesia. The typical Rai stone is carved out of crystalline limestone, and shaped like a disk with a hole in the center. Some of the stones weighed four metric tons, the weight of a typical elephant. Limestones are not native to Yap Island. They had to quarry and canoe from the neighboring island of Palau or Guam, requiring hundreds of people to transport them. These rocks are placed in a prominent location on the Yap island for everyone to see. The owner of the stone could use it as a payment method without moving the stone. All they had to do was to announce to all townsfolk that the stone’s ownership had now moved to the recipient. The very high cost of procuring Rai stones made it a sound form of money. That soundness changed in 1871 when an Irish-American captain by the name of David O’Keefe was shipwrecked on the shores of Yap island and revived by the locals. O’Keefe immediately saw a profit opportunity by selling coconuts found on Yap island to producers of coconut oil. He couldn’t entice the locals to work for him as they were content with their lives. O’Keefe wouldn’t take no for an answer. He sailed to Hong Kong, procured a large boat and explosives. Using modern tools, O’Keefe was able to easily procure huge quantities of Rai stones into Yap island.

  • Cryptocurrency: a Primer for Policy-Makers
    August 2019 Cryptocurrency: A Primer for Policy-Makers Zack Gold and Megan McBride Approved for public release. Unlimited distribution. CRM-2019-U-020185-Final Abstract This primer is an effort to address a gap in knowledge about cryptocurrencies and the cryptocurrency ecosystem among the policymaking community and advance the understanding of cryptocurrencies and consideration of their national security implications. Cryptocurrencies are strictly digital currencies, are typically overseen by a decentralized peer-to-peer community, and are secured through cryptography. We use clear, non-technical language to describe complex concepts and demystify overly technical terms in order to explain the technical and economic aspects of cryptocurrency, why they are used, and the benefits and drawbacks to cryptocurrencies compared to conventional currencies—like the US dollar. We conclude by considering some cryptocurrency-related issues of which greater exploration would benefit US national security. This document contains the best opinion of CNA at the time of issue. It does not necessarily represent the opinion of the sponsor or client. Distribution Approved for public release. Unlimited distribution.

Copyright © 2019 CNA. All rights reserved Executive Summary In 2017, the value of one Bitcoin skyrocketed to more than $20,000. Media coverage increased, and even people who did not join the investment frenzy became aware of so-called “cryptocurrencies.” Despite this familiarity, few actually understand cryptocurrencies and the implications they may have on US interests, from global finance to national security to good governance.

From Rai stones in Palau, to knives in China, to jewelry in Egypt and all the way to our current fiat sys- 3300 tem, money has been the agreed upon way to store value to exchange for goods and services later. The currency/commodity’s worth stems from the value society places Years on the medium. As history has progressed, various commodities such as gold and Since 1984 silver, have been perceived as currencies, for people to have an alternative to system- atic currency. Regardless of country specific success or detriment, people perceive gold as being a tradeable asset (a currency) for goods or services, thus giving it value.

    Rapporto Zotero zotero://report/library/collections/GXG5S9NZ/items?sort=title&direct... A Hypergraph-Based Blockchain Model and Application in Internet of Things- Enabled Smart Homes Tipo Articolo di periodico specializzato Autore Chao Qu Autore Ming Tao Autore Ruifen Yuan Volume 18 Numero di fascicolo 9 Titolo della pubblicazione Sensors (Basel, Switzerland) ISSN 1424-8220 Data 2018 DOI 10.3390/s18092784 Catalogo della biblioteca unito-tutto.com Abstract With the fast development and expansion of the Internet of Things (IoT), billions of smart devices are being continuously connected, and smart homes, as a typical IoT application, are providing people with various convenient applications, but face security and privacy issues. The idea of Blockchain (BC) theory has brought about a potential solution to the IoT security problem. The emergence of blockchain technology has brought about a change of decentralized management, providing an effective solution for the protection of network security and privacy. On the other hand, the smart devices in IoT are always lightweight and have less energy and memory. This makes the application of blockchain difficult. Against this background, this paper proposes a blockchain model based on hypergraphs. The aims of this model are to reduce the storage consumption and to solve the additional security issues. In the model, we use the hyperedge as the organization of storage nodes and convert the entire networked data storage into part network storage. We discuss the design of the model and security strategy in detail, introducing some use cases in a smart home network and evaluating the storage performance of the model through simulation experiments and an evaluation of the network.
