The DAO (organization)
The DAO, whose logo featured a capital letter Đ, was a digital decentralized autonomous organization and a form of investor-directed venture capital fund. After launching in April 2016 via a token sale, it became one of the largest crowdfunding campaigns in history. The DAO had an objective to provide a new decentralized business model for organizing both commercial and non-profit enterprises. It was instantiated on the Ethereum blockchain and had no conventional management structure or board of directors. The code of the DAO is open-source. In June 2016, users exploited a vulnerability in The DAO code to enable them to siphon off one-third of The DAO's funds to a subsidiary account. The Ethereum community controversially decided to hard-fork the Ethereum blockchain to restore approximately all funds to the original contract. This split the Ethereum blockchain into two branches, each with its own cryptocurrency, where the original unforked blockchain continued as Ethe ...

Ethereum
Ethereum is a decentralized, open-source blockchain with smart contract functionality. Ether ( Abbreviation: ETH; sign: Ξ) is the native cryptocurrency of the platform. Among cryptocurrencies, ether is second only to bitcoin in market capitalization. Ethereum was conceived in 2013 by programmer Vitalik Buterin. Additional founders of Ethereum included Gavin Wood, Charles Hoskinson, Anthony Di Iorio and Joseph Lubin. In 2014, development work began and was crowdfunded, and the network went live on 30 July 2015. Ethereum allows anyone to deploy permanent and immutable decentralized applications onto it, with which users can interact. Decentralized finance (DeFi) applications provide a broad array of financial services without the need for typical financial intermediaries like brokerages, exchanges, or banks, such as allowing cryptocurrency users to borrow against their holdings or lend them out for interest. Ethereum also allows users to create and exchange NFTs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Open Source Software
Open-source software (OSS) is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2008 report by the Standish Group stated that adoption of open-source software models has resulted in savings of about $60 billion per year for consumers. Open source code can be used for studying and allows capable end users to adapt software to their personal needs in a similar way user scripts ...

Kraken (company)
Kraken is a United States–based cryptocurrency exchange and bank, founded in 2011. It was one of the first bitcoin exchanges to be listed on Bloomberg Terminal and is reportedly valued at $10.8 billion USD, as of mid-summer 2022. As of 2020, Kraken had US$1.1 billion in revenue. History Kraken was co-founded in 2011 by Jesse Powell, an alumnus of California State University, Sacramento with Thanh Luu. Powell was a consultant for Mt. Gox in resolving a security issue, and began working on Kraken as a replacement anticipating its death; Gox would indeed collapse in 2014, failing security audits. In September 2013, Kraken was launched, offering Bitcoin, Litecoin, and euro trades initially before going on to add additional currencies and margin trading. A few months earlier, Kraken had joined other US Bitcoin players to form the "Committee for the Establishment of the Digital Asset Transfer Authority" as the self-regulatory group of the industry. In March 2014, Kraken received ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Listing (finance)
In corporate finance, a listing refers to the company's shares being on the list (or board) of stock that are officially traded on a stock exchange. Some stock exchanges allow shares of a foreign company to be listed and may allow dual listing, subject to conditions. Normally the issuing company is the one that applies for a listing but in some countries an exchange can list a company, for instance because its stock is already being traded via informal channels. Stocks whose market value and/or turnover fall below critical levels may be delisted by the exchange. Delisting often arises from a merger or takeover, or the company going private. Requirements Each stock exchange has its own listing requirements or rules. Initial listing requirements usually include supplying a history of a few years of financial statements (not required for "alternative" markets targeting young firms); a sufficient size of the amount being placed among the general public (the free float), both i ...

Ethereum Classic
Ethereum Classic is an open source, blockchain-based distributed computing platform featuring smart contract (scripting) functionality. It supports a modified version of Nakamoto consensus via transaction-based state transitions executed on a public Ethereum Virtual Machine (EVM). Ethereum Classic maintains the original, unaltered history of the Ethereum network. The Ethereum project's mainnet initially released via Frontier on 30 July 2015. However, due to a hack of a third-party project, the Ethereum Foundation created a new version of the Ethereum mainnet on 20 July 2016 with an ''irregular state change'' implemented that erased The DAO theft from the Ethereum blockchain history. The Ethereum Foundation endorsed the new, altered version of the Ethereum blockchain; Ethereum (code: ETH). The older, unaltered version of Ethereum was renamed and continued on as Ethereum Classic (code: ETC). Ethereum Classic's native Ether token is a cryptocurrency traded on digital currency ex ...

Fork (blockchain)
In blockchain, a fork is defined variously as: * "what happens when a blockchain diverges into two potential paths forward" * "a change in protocol", or * a situation that "occurs when two or more blocks have the same block height" Forks are related to the fact that different parties need to use common rules to maintain the history of the blockchain. When parties are not in agreement, alternative chains may emerge. While most forks are short-lived some are permanent. Short-lived forks are due to the difficulty of reaching fast consensus in a distributed system. Whereas permanent forks (in the sense of protocol changes) have been used to add new features to a blockchain, they can also be used to reverse the effects of hacking such as the case with Ethereum and Ethereum Classic, or avert catastrophic bugs on a blockchain as was the case with the bitcoin fork on 6 August 2010. Blockchain forks have been widely discussed in the context of the bitcoin scalability problem. Types ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exploit (computer Security)
An exploit (from the English verb ''to exploit'', meaning "to use something to one’s own advantage") is a piece of software, a chunk of data, or a sequence of commands that takes advantage of a bug or vulnerability to cause unintended or unanticipated behavior to occur on computer software, hardware, or something electronic (usually computerized). Such behavior frequently includes things like gaining control of a computer system, allowing privilege escalation, or a denial-of-service (DoS or related DDoS) attack. In lay terms, some exploit is akin to a 'hack'. Classification There are several methods of classifying exploits. The most common is by how the exploit communicates to the vulnerable software. A ''remote exploit'' works over a network and exploits the security vulnerability without any prior access to the vulnerable system. A ''local exploit'' requires prior access to the vulnerable system and usually increases the privileges of the person running the exploit past t ...
