Solidity (programming Language)
Solidity is an object-oriented programming language for implementing smart contracts on various blockchain platforms, most notably, Ethereum. It was developed by Christian Reitwiessner, Alex Beregszaszi, and several former Ethereum core contributors. Programs in Solidity run on Ethereum Virtual Machine. History Solidity was proposed in August 2014 by Gavin Wood; the language was later developed by the Ethereum project's Solidity team, led by Christian Reitwiessner. Solidity is the primary language on Ethereum as well as on other private blockchains, such as the enterprise-oriented Hyperledger Fabric blockchain. SWIFT deployed a proof of concept using Solidity running on Hyperledger Fabric. Description Solidity is a statically typed programming language designed for developing smart contracts that run on the Ethereum Virtual Machine (EVM). Solidity uses ECMAScript-like syntax which makes it familiar for existing web developers; however unlike ECMAScript it has static typi ...

Object-oriented Programming
Object-oriented programming (OOP) is a programming paradigm based on the concept of " objects", which can contain data and code. The data is in the form of fields (often known as attributes or ''properties''), and the code is in the form of procedures (often known as '' methods''). A common feature of objects is that procedures (or methods) are attached to them and can access and modify the object's data fields. In this brand of OOP, there is usually a special name such as or used to refer to the current object. In OOP, computer programs are designed by making them out of objects that interact with one another. OOP languages are diverse, but the most popular ones are class-based, meaning that objects are instances of classes, which also determine their types. Many of the most widely used programming languages (such as C++, Java, Python, etc.) are multi-paradigm and they support object-oriented programming to a greater or lesser degree, typically in combination with ...

C3 Linearization
"In object-oriented systems with multiple inheritance, some mechanism must be used for resolving conflicts when inheriting different definitions of the same property from multiple superclasses." C3 superclass linearization is an algorithm used primarily to obtain the order in which methods should be inherited in the presence of multiple inheritance. In other words, the ''output'' of C3 superclass linearization is a deterministic Method Resolution Order (MRO). C3 superclass linearization is called C3 because it "is consistent with three properties": * a consistent extended precedence graph, * preservation of local precedence order, and * fitting a monotonicity criterion. It was first published at the 1996 OOPSLA conference, in a paper entitled "A Monotonic Superclass Linearization for Dylan". It was adapted to the Open Dylan implementation in January 2012 following an enhancement proposal. It has been chosen as the default algorithm for method resolution in Python 2.3 ( ...

Hashgraph
Hashgraph is a distributed ledger technology that has been described as an alternative to blockchains. The hashgraph technology is currently patented, is used by the public ledger Hedera, and there is a grant to implement the patent as a result of the Apache 2.0's Grant of Patent License (provision #3) so long as the implementation conforms to the terms of the Apache license. The native cryptocurrency of the Hedera Hashgraph system is HBAR. Unlike blockchains, hashgraphs do not bundle data into blocks or use miners to validate transactions. Instead, hashgraphs use a "gossip about gossip" protocol where the individual nodes on the network "gossip" about transactions to create directed acyclic graphs that time-sequence transactions. Each "gossip" message contains one or more transactions plus a timestamp, a digital signature, and cryptographic hashes of two earlier events. This makes Hashgraph form an asynchronous Byzantine Fault-Tolerant (aBFT) consensus algorithm. Hashgraph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Bitcoin
Bitcoin ( abbreviation: BTC; sign: ₿) is a decentralized digital currency that can be transferred on the peer-to-peer bitcoin network. Bitcoin transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. The cryptocurrency was invented in 2008 by an unknown person or group of people using the name Satoshi Nakamoto. The currency began use in 2009, when its implementation was released as open-source software. The word "''bitcoin''" was defined in a white paper published on October 31, 2008. It is a compound of the words ''bit'' and ''coin''. The legality of bitcoin varies by region. Nine countries have fully banned bitcoin use, while a further fifteen have implicitly banned it. A few governments have used bitcoin in some capacity. El Salvador has adopted Bitcoin as legal tender, although use by merchants remains low. Ukraine has accepted cryptocurrency donations to fund the resistance to the 2022 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Counterparty (technology)
Counterparty is a peer-to-peer financial platform and distributed, open source Internet protocol built on top of the Bitcoin blockchain and network. It was one of the most well-known "Bitcoin 2.0" (later known as non-fungible token) platforms in 2014, along with Mastercoin, Ethereum, Colored Coins, Ripple and BitShares. It is a "metacoin"-type protocol. It provides such features as tradable user-created currencies, additional financial instruments and a decentralized asset exchange. Over time it has developed a strong user-base, mostly due to the protocol hosting the non-fungible token collections Spells Of Genesis (2015) and Rare Pepe (2016). History In November of 2014, Counterparty added support for the Ethereum Virtual Machine (EVM) to the Counterparty protocol and allowing all Ethereum decentralized applications to be run on the Bitcoin blockchain within the Counterparty protocol. In 2014, Counterparty was part of a plan by Overstock.com to issue and trade legal secu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binance Smart Chain
Binance is a cryptocurrency exchange which is the largest exchange in the world in terms of daily trading volume of cryptocurrencies. It was founded in 2017 and is registered in the Cayman Islands. Binance was founded by Changpeng Zhao, a developer who had previously created high frequency trading software. Binance was initially based in China, but later moved its headquarters out of China shortly before the Chinese government imposed regulations on cryptocurrency trading.

Avalanche (blockchain Platform)
Avalanche is a decentralized, open-source proof of stake blockchain with smart contract functionality. AVAX is the native cryptocurrency of the platform. History Avalanche began as a protocol for solving for consensus in a network of unreliable machines, where failures may be crash-fault or Byzantine. The protocol's fundamentals were first shared on the InterPlanetary File System (IPFS) in May 2018 by a pseudonymous group of enthusiasts going by the name "Team Rocket". Avalanche was later developed by researchers from Cornell University led by Emin Gün Sirer and doctoral students Maofan "Ted" Yin and Kevin Sekniqi. Following the research stage, a startup technology company was founded to develop a blockchain network that would meet finance industry requirements. In March, 2020, the AVA codebase (Developer Accelerator Program or AVA DAP) for the Avalanche consensus protocol was released as open-source and became available to the public. In September, 2020, the company also i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Medium (website)
Medium is an American online publishing platform developed by Evan Williams and launched in August 2012. It is owned by A Medium Corporation. The platform is an example of social journalism, having a hybrid collection of amateur and professional people and publications, or exclusive blogs or publishers on Medium, and is regularly regarded as a blog host. Williams, previously co-founder of Blogger and Twitter, initially developed Medium as a means to publish writings and documents longer than Twitter's 140-character (now 280-character) maximum. In March 2021, Medium announced a change in its publishing strategy and business model. The change is to its mix of paid journalists working on its own publications – this will be proportionally reduced – versus its support of independent writers, which will increase. History 2012 (launched) - 2016 Evan Williams, Twitter co-founder and former CEO, created Medium to encourage users to create posts longer than the then 140-character ...
