Bitcoin Buried In Newport Landfill
In 2013, Welsh computer engineer James Howells mistakenly disposed of a laptop hard drive containing the private key for 8,000 Bitcoin in the Docksway landfill in Newport, Wales. Howells subsequently assembled a team of specialists and secured funding to excavate the site, but Newport City Council refused permission, citing the cost and environmental impact of the search. If the coins are discovered, Howells proposes distributing 30% of the proceedings among the council and the population of Newport. the missing Bitcoin was worth (). In December 2024, Howells sued the council for £495 million, with the council contesting that the device is now its property. The attempted recovery of the missing Bitcoin has been likened to a digital treasure hunt. Howells and his team are confident that retrieval of the data remains possible, while the council continues to profess its scepticism. Following a hearing, the High Court dismissed Howells' claim in January 2025, ruling that it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Distributed Ledger
A distributed ledger (also called a shared ledger or distributed ledger technology or DLT) is a system whereby replicated, shared, and synchronized digital data is geographically spread (distributed) across many sites, countries, or institutions. Its fundamental rationale is Argumentum ad populum whereby its veracity relies on a popular or majority of nodes to force the system to agree. In contrast to a centralized database, a distributed ledger does not require a central administrator, and consequently does not have a Single point of failure, single (central) point-of-failure. In general, a distributed ledger requires a peer-to-peer, peer-to-peer (P2P) computer network and Consensus (computer science), consensus algorithms so that the ledger is reliably replicated across distributed computer nodes (servers, clients, etc.). The most common form of distributed ledger technology is the blockchain (commonly associated with the bitcoin cryptocurrency), which can either be on a public or ...

Kilobytes
The kilobyte is a multiple of the unit byte for digital information. The International System of Units (SI) defines the prefix '' kilo'' as a multiplication factor of 1000 (103); therefore, one kilobyte is 1000 bytes.International Standard IEC 80000-13 Quantities and Units – Part 13: Information science and technology, International Electrotechnical Commission (2008). The internationally recommended unit symbol for the kilobyte is kB. In some areas of information technology, particularly in reference to random-access memory capacity, ''kilobyte'' instead often refers to 1024 (210) bytes. This arises from the prevalence of sizes that are powers of two in modern digital memory architectures, coupled with the coincidence that 210 differs from 103 by less than 2.5%. The kibibyte is defined as 1024 bytes, avoiding the ambiguity issues of the ''kilobyte''.International Standard IEC 80000-13 Quantities and Units – Part 13: Information science and technology, Internatio ...

Dell XPS
XPS ("Extreme Performance System") is a line of consumer-oriented laptop and desktop computers manufactured by Dell since 1993. History In the early 1990s, Dell primarily targeted its products at businesses rather than consumers. In early 1993, Dell executives met to address how to pursue the emerging consumer market in the US (led by Gateway Inc., Gateway 2000, later known as Gateway), and decided to launch a new product line to compete with Gateway. At that time, Dell's annual revenue was less than $500 million, and founder Michael Dell was still directly involved in key decisions. Vernon Weiss, the product manager, led the project and managed product marketing, while Brian Zucker oversaw architecture and engineering. In September 1993, the first two products in the XPS line were announced, initially as part of the Dell Dimension series. The first generation XPS systems were available in both desktop and tower configurations. The earliest known XPS PC, the Dell Dimension XP ...

Bitcoin Mining
The bitcoin protocol is the set of rules that govern the functioning of bitcoin. Its key components and principles are: a peer-to-peer decentralized network with no central oversight; the blockchain technology, a public ledger that records all bitcoin transactions; mining and proof of work, the process to create new bitcoins and verify transactions; and cryptographic security. Users broadcast cryptographically signed messages to the network using bitcoin cryptocurrency wallet software. These messages are proposed transactions, changes to be made in the ledger. Each node has a copy of the ledger's entire transaction history. If a transaction violates the rules of the bitcoin protocol, it is ignored, as transactions only occur when the entire network reaches a consensus that they should take place. This "full network consensus" is achieved when each node on the network verifies the results of a proof-of-work operation called ''mining''. Mining packages groups of transactions i ...

Bitcoin Difficulty
Bitcoin (abbreviation: BTC; sign: ₿) is the first decentralized cryptocurrency. Based on a free-market ideology, bitcoin was invented in 2008 when an unknown entity published a white paper under the pseudonym of Satoshi Nakamoto. Use of bitcoin as a currency began in 2009, with the release of its open-source implementation. In 2021, El Salvador adopted it as legal tender. It is mostly seen as an investment and has been described by some scholars as an economic bubble. As bitcoin is pseudonymous, its use by criminals has attracted the attention of regulators, leading to its ban by several countries . Bitcoin works through the collaboration of computers, each of which acts as a node in the peer-to-peer bitcoin network. Each node maintains an independent copy of a public distributed ledger of transactions, called a blockchain, without central oversight. Transactions are validated through the use of cryptography, preventing one person from spending another person's bitcoin, ...

Emergency Response System
An emergency is an urgent, unexpected, and usually dangerous situation that poses an immediate risk to health, life, property, or environment and requires immediate action. Most emergencies require urgent intervention to prevent a worsening of the situation, although in some situations, mitigation may not be possible and agencies may only be able to offer palliative care for the aftermath. While some emergencies are self-evident (such as a natural disaster that threatens many lives), many smaller incidents require that an observer (or affected party) decide whether it qualifies as an emergency. The precise definition of an emergency, the agencies involved and the procedures used, vary by jurisdiction, and this is usually set by the government, whose agencies (emergency services) are responsible for emergency planning and management. Defining an emergency An incident, to be an emergency, conforms to one or more of the following, if it: * Poses an immediate threat to life, he ...

Fiat Money
Fiat money is a type of government-issued currency that is not backed by a precious metal, such as gold or silver, nor by any other tangible asset or commodity. Fiat currency is typically designated by the issuing government to be legal tender, and is authorized by government regulation. Since the end of the Bretton Woods system in 1976 by the Jamaica Accords, the major currencies in the world are fiat money. Fiat money generally does not have intrinsic value and does not have use value. It has value only because the individuals who use it as a unit of account or, in the case of currency, a medium of exchange agree on its value. They trust that it will be accepted by merchants and other people as a means of payment for liabilities. Fiat money is an alternative to commodity money, which is a currency that has intrinsic value because it contains, for example, a precious metal such as gold or silver which is embedded in the coin. Fiat also differs from representative mone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2008 Financial Crisis
The 2008 financial crisis, also known as the global financial crisis (GFC), was a major worldwide financial crisis centered in the United States. The causes of the 2008 crisis included excessive speculation on housing values by both homeowners and financial institutions that led to the 2000s United States housing bubble, exacerbated by predatory lending for subprime mortgages and deficiencies in regulation. Cash out refinancings had fueled an increase in consumption that could no longer be sustained when home prices declined. The first phase of the crisis was the subprime mortgage crisis, which began in early 2007, as mortgage-backed securities (MBS) tied to U.S. real estate, and a vast web of Derivative (finance), derivatives linked to those MBS, collapsed in value. A liquidity crisis spread to global institutions by mid-2007 and climaxed with the bankruptcy of Lehman Brothers in September 2008, which triggered a stock market crash and bank runs in several countries. The crisis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bowman (communications System)
Bowman is the name of the tactical communications system used by the British Armed Forces. The Bowman C4I system consists of a range of HF radio, VHF radio and UHF radio sets designed to provide secure integrated voice, data services to dismounted soldiers, individual vehicles and command HQs up to Division level. Bowman has a number of specific applications installed on the base radio infrastructure known as BISAs. Bowman has been released incrementally as a number of phased capability releases, known as BCIP releases, with BCIP 5.5 being released in the field in 2013. Bowman replaced the Clansman series of radios. As of 2016, the MoD publicised plans to replace Bowman with a system named Morpheus. Procurement history The concept of Bowman dates from a 1989 UK MoD General Staff Requirement (GSR) for a system to replace the ageing Clansman radio system. The GSR was subsequently modified to accommodate post Cold War scenarios. The procurement had a long and chequered hist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Bitcoin
Bitcoin is a cryptocurrency, a digital asset that uses cryptography to control its creation and management rather than relying on central authorities. Originally designed as a medium of exchange, Bitcoin is now primarily regarded as a store of value. The history of bitcoin started with its invention and implementation by Satoshi Nakamoto, who integrated many existing ideas from the cryptography community. Over the course of bitcoin's history, it has undergone rapid growth to become a significant store of value both on- and offline. From the mid-2010s, some businesses began accepting bitcoin in addition to traditional currencies. Background Prior to the release of bitcoin, there were a number of digital cash technologies, starting with the issuer-based ecash protocols of David Chaum and Stefan Brands. The idea that solutions to computational puzzles could have some value was first proposed by cryptographers Cynthia Dwork and Moni Naor in 1992. 31 October 1996 NSA paper 12 years ...
