Cardano (blockchain Platform)
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. Cardano's development began in 2015, led by Ethereum co-founder Charles Hoskinson. The project is overseen and supervised by the Cardano Foundation based in Zug, Switzerland. When launched in 2017, it was the largest cryptocurrency to use a proof-of-stake blockchain, which is seen as a greener alternative to proof-of-work protocols. History After leaving Ethereum in 2014 Charles Hoskinson and Jeremy Wood set out their plans for Cardano in 2015. Hoskinson had left Ethereum after a dispute with another co-founder, Vitalik Buterin. Hoskinson wanted to accept venture capital and create a company, while Buterin wanted to keep it as a nonprofit organization. Woods and Hoskinson co-founded the business IOHK to develop blockchains for use use by corporations, governments, and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cryptocurrency
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. Individual coin ownership records are stored in a digital ledger, which is a computerized database using strong cryptography to secure transaction records, control the creation of additional coins, and verify the transfer of coin ownership. Despite their name, cryptocurrencies are not considered to be currencies in the traditional sense, and while varying treatments have been applied to them, including classification as commodities, securities, and currencies, cryptocurrencies are generally viewed as a distinc ...

Ouroboros (protocol)
Ouroboros is a family of proof-of-stake consensus protocols used in the Cardano and Polkadot blockchains. It can run both permissionless and permissioned blockchains. Ouroboros was published as "the first provable secure PoS consensus protocol". It was postulated by an academic team led by Aggelos Kiayias at the Annual International Cryptology Conference in 2017. Later that year, Ouroboros (Classic) was implemented by IOHK as the basis of the Cardano blockchain platform and various upgrades. Ouroboros versions include: * Ouroboros BFT was an interim version used in 2020 to enable the switch between the Classic and Praos versions of Cardano using a hard fork combinator that preserved the blockchain history; * Ouroboros Praos (2017) provided security against fully-adaptive corruption in the semi-synchronous model. In 2020, this version was used to introduce decentralized block production on Cardano by stake pools; * Ouroboros Genesis (2018) provides security with a dynamic p ...

Granted a royal charter by King James VI in 1582 and officially opened in 1583, it is one of Scotland's four ancient universities and the sixth-oldest university in continuous operation in the English-speaking world. The university played an important role in Edinburgh becoming a chief intellectual centre during the Scottish Enlightenment and contributed to the city being nicknamed the " Athens of the North." Edinburgh is ranked among the top universities in the United Kingdom and the world. Edinburgh is a member of several associations of research-intensive universities, including the Coimbra Group, League of European Research Universities, Russell Group, Una Europa, and Universitas 21. In the fiscal year ending 31 July 2021, it had a total income of £1.176 billion, of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Parliament
The European Parliament (EP) is one of the legislative bodies of the European Union and one of its seven institutions. Together with the Council of the European Union (known as the Council and informally as the Council of Ministers), it adopts European legislation, following a proposal by the European Commission. The Parliament is composed of 705 members (MEPs). It represents the second-largest democratic electorate in the world (after the Parliament of India), with an electorate of 375 million eligible voters in 2009. Since 1979, the Parliament has been directly elected every five years by the citizens of the European Union through universal suffrage. Voter turnout in parliamentary elections decreased each time after 1979 until 2019, when voter turnout increased by eight percentage points, and rose above 50% for the first time since 1994. The voting age is 18 in all EU member states except for Malta and Austria, where it is 16, and Greece, where it is 17. Although the E ...

Nonprofit Organization
A nonprofit organization (NPO) or non-profit organisation, also known as a non-business entity, not-for-profit organization, or nonprofit institution, is a legal entity organized and operated for a collective, public or social benefit, in contrast with an entity that operates as a business aiming to generate a Profit (accounting), profit for its owners. A nonprofit is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties. An array of organizations are nonprofit, including some political organizations, schools, business associations, churches, social clubs, and consumer cooperatives. Nonprofit entities may seek approval from governments to be Tax exemption, tax-exempt, and some may also qualify to receive tax-deductible contributions, but an entity may incorporate as a nonprofit entity without securing tax-exempt status. Key aspects of nonprofits are accountability, trustworth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venture Capital
Venture capital (often abbreviated as VC) is a form of private equity financing that is provided by venture capital firms or funds to startups, early-stage, and emerging companies that have been deemed to have high growth potential or which have demonstrated high growth (in terms of number of employees, annual revenue, scale of operations, etc). Venture capital firms or funds invest in these early-stage companies in exchange for equity, or an ownership stake. Venture capitalists take on the risk of financing risky start-ups in the hopes that some of the firms they support will become successful. Because startups face high uncertainty, VC investments have high rates of failure. The start-ups are usually based on an innovative technology or business model and they are usually from high technology industries, such as information technology (IT), clean technology or biotechnology. The typical venture capital investment occurs after an initial "seed funding" round. The first ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitalik Buterin
Vitaly "Vitalik" Buterin (born 1994) is a Russian-Canadian computer programmer and founder of Ethereum. Buterin became involved with cryptocurrency early in its inception, co-founding ''Bitcoin Magazine'' in 2011. In 2014, Buterin deployed Ethereum on blockchain with Dimitry Buterin, Gavin Wood, Charles Hoskinson, Anthony Di Iorio and Joseph Lubin (entrepreneur), Joseph Lubin. Early life and education Buterin was born in Kolomna, Russia, in 1994. His father was a computer scientist. He lived in the area until the age of six when his parents Immigration to Canada, emigrated to Canada in search of better employment opportunities. While in grade three of elementary school in Canada, Buterin was placed into a class for gifted children and was drawn to mathematics, programming, and economics. Buterin then attended The Abelard School, a private high school in Toronto. Buterin learned about Bitcoin, from his father, Dimitry Buterin at the age of 17. After high school, Buterin attend ...

Proof-of-work
Proof of work (PoW) is a form of cryptographic proof in which one party (the ''prover'') proves to others (the ''verifiers'') 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. Proof of work was later popularized by Bitcoin as a foundation for consensus in a permissionless decentralized network, in which miners compete to append blocks and mint new currency, each miner experiencing a success probability proportional to the computational effort expended. PoW and PoS (proof of stake) remain the two best known S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Computing
Green computing, green IT, or ICT sustainability, is the study and practice of environmentally sustainable computing or IT. The goals of green computing are similar to green chemistry: reduce the use of hazardous materials, maximize energy efficiency during the product's lifetime, the recyclability or biodegradability of defunct products and factory waste. Green computing is important for all classes of systems, ranging from handheld systems to large-scale data centers. Many corporate IT departments have green computing initiatives to reduce the environmental effect of their IT operations. Yet it is also clear that the environmental footprint of the sector is significant, estimated at 5-9% of the world's total electricity use and more than 2% of all emissions. Data centres and telecommunications will need to become more energy efficient, reuse waste energy, and use more renewable energy sources. They can and should become climate neutral by 2030. Origins In 1992, the U.S. Enviro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
