A cypherpunk is any individual advocating widespread use of strong cryptography and privacy-enhancing technologies as a route to social and political change. Originally communicating through the Cypherpunks electronic mailing list, informal groups aimed to achieve privacy and security through proactive use of cryptography. Cypherpunks have been engaged in an active movement since at least the late 1980s.
Crypto-anarchism or cyberanarchism is a political ideology focusing on protection of privacy, political freedom, and economic freedom, the adherents of which use cryptographic software for confidentiality and security while sending and receiving information over computer networks. In his 1988 "Crypto Anarchist Manifesto", Timothy C. May introduced the basic principles of crypto-anarchism, encrypted exchanges ensuring total anonymity, total freedom of speech, and total freedom to trade. In 1992, he read the text at the founding meeting of the cypherpunk movement.
Financial services are economic services provided by the finance industry, which together encompass a broad range of service sector firms that provide financial management, including credit unions, banks, credit-card companies, insurance companies, accountancy companies, consumer-finance companies, stock brokerages, investment funds, individual asset managers, and some government-sponsored enterprises.
Underwriting (UW) services are provided by some large financial institutions, such as banks, insurance companies and investment houses, whereby they guarantee payment in case of damage or financial loss and accept the financial risk for liability arising from such guarantee. An underwriting arrangement may be created in a number of situations including insurance, issues of security in a public offering, and bank lending, among others. The person or institution that agrees to sell a minimum number of securities of the company for commission is called the underwriter.
Proof of work (PoW) is a form of cryptographic proof in which one party proves to others that a certain amount of a specific computational effort has been expended. Verifiers can subsequently confirm this expenditure with minimal effort on their part. The concept was invented by Moni Naor and Cynthia Dwork in 1993 as a way to deter denial-of-service attacks and other service abuses such as spam on a network by requiring some work from a service requester, usually meaning processing time by a computer. The term "proof of work" was first coined and formalized in a 1999 paper by Markus Jakobsson and Ari Juels.
A financial crisis is any of a broad variety of situations in which some financial assets suddenly lose a large part of their nominal value. In the 19th and early 20th centuries, many financial crises were associated with banking panics, and many recessions coincided with these panics. Other situations that are often called financial crises include stock market crashes and the bursting of other financial bubbles, currency crises, and sovereign defaults. Financial crises directly result in a loss of paper wealth but do not necessarily result in significant changes in the real economy.
Cryptography is the practice and study of encrypting information, or in other words, securing information from unauthorized access. There are many different cryptography laws in different nations. Some countries prohibit export of cryptography software and/or encryption algorithms or cryptoanalysis methods. Some countries require decryption keys to be recoverable in case of a police investigation.
Virtual currency, or virtual money, is a digital currency that is largely unregulated, issued and usually controlled by its developers, and used and accepted electronically among the members of a specific virtual community. In 2014, the European Banking Authority defined virtual currency as "a digital representation of value that is neither issued by a central bank or a public authority, nor necessarily attached to a fiat currency but is accepted by natural or legal persons as a means of payment and can be transferred, stored or traded electronically." A digital currency issued by a central bank is referred to as a central bank digital currency.
Cryptography, or cryptology, is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications.
The mortgage industry of the United States is a major financial sector. The federal government created several programs, or government sponsored entities, to foster mortgage lending, construction and encourage home ownership. These programs include the Government National Mortgage Association, the Federal National Mortgage Association and the Federal Home Loan Mortgage Corporation.
The 2007–2008 financial crisis, or Global Financial Crisis (GFC), was a severe worldwide economic crisis that occurred in the early 21st century. It was the most serious financial crisis since the Great Depression (1929). Predatory lending targeting low-income homebuyers, excessive risk-taking by global financial institutions, and the bursting of the United States housing bubble culminated in a "perfect storm".
A cryptocurrency, crypto-currency, or crypto is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it. It is a decentralized system for verifying that the parties to a transaction have the money they claim to have, eliminating the need for traditional intermediaries, such as banks, when funds are being transferred between two entities.
Vincent Moscaritolo is a retired American computer security expert known for his work in encryption applications for mobile devices. After decades in the computer industry, he now volunteers as a search and rescue professional for his local sheriff's department. Vinnie has also been prolifically writing on Substack about topics such as automotive hacking, software-defined radio, Raspberry Pi, and Search and Rescue.
Vincent Aron Cate is a cryptography software developer based in Anguilla. He graduated from the University of California, Berkeley and ran an Atari hardware business in the 1980s before beginning a Ph.D. programme at Carnegie Mellon University, but dropped out and moved to Anguilla to pursue business opportunities there. In his new home, he would go on to establish an internet service provider, a computer club for young students, and an annual cryptography conference. A former U.S. citizen, he gave up his U.S. citizenship in 1998 in protest of U.S. laws on the export of cryptography.
A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Since each block contains information about the previous block, they effectively form a chain, with each additional block linking to the ones before it. Consequently, blockchain transactions are irreversible in that, once they are recorded, the data in any given block cannot be altered retroactively without altering all subsequent blocks.
A smart bond is a specific type of an automated bond contract that uses the capabilities of blockchain databases that can operate as cryptographically-secure yet open and transparent general ledgers. This is sometimes referred to as Distributed Ledger Technology (DLT). It is one of a class of financial instruments known as a smart contract, "a computerized transaction protocol that executes the terms of a contract."
Cardano is a public blockchain platform. It is open-source and decentralized, with consensus achieved using proof of stake. It can facilitate peer-to-peer transactions with its internal cryptocurrency, ADA.
The 1994 bond market crisis, or Great Bond Massacre, was a sudden drop in bond market prices across the developed world. It began in Japan and the United States (US), and spread through the rest of the world. After the recession of the early 1990s, historically low interest rates in many industrialized nations preceded an unexpectedly volatile year for bond investors, including those that held on to mortgage debts. Over 1994, a rise in rates, along with the relatively quick spread of bond market volatility across international borders, resulted in a mass sell-off of bonds and debt funds as yields rose beyond expectations. This was especially the case for instruments with comparatively longer maturities attached. Some financial observers argued that the plummet in bond prices was triggered by the Federal Reserve's decision to raise rates by 25 basis points in February, in a move to counter inflation. At about $1.5 trillion in lost market value across the globe, the crash has been described as the worst financial event for bond investors since 1927.
