DApp
A decentralised application (DApp, dApp, Dapp, or dapp) is an application that can operate autonomously, typically through the use of smart contracts, that run on a decentralized computing, blockchain or other distributed ledger system. Like traditional applications, DApps provide some function or utility to its users. However, unlike traditional applications, DApps operate without human intervention and are not owned by any one entity, rather DApps distribute tokens that represent ownership. These tokens are distributed according to a programmed algorithm to the users of the system, diluting ownership and control of the DApp. Without any one entity controlling the system, the application is therefore decentralised. Decentralised applications have been popularised by distributed ledger technologies (DLT), such as the Ethereum or Cardano blockchain, on which DApps are built, amongst other public blockchains. In social media the largest decentralized platform is Bluesky. DApps ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptocurrency Wallet
A cryptocurrency wallet is a device, physical medium, program or an online service which stores the Public-key cryptography, public and/or private keys for cryptocurrency transactions. In addition to this basic function of storing the keys, a cryptocurrency wallet more often offers the functionality of encrypting and/or Digital signature, signing information. Signing can for example result in executing a smart contract, a cryptocurrency transaction (see "bitcoin transaction" image), Digital signature#Authentication, identification, or Electronic signature, legally signing a 'document' (see "application form" image). History In 2008 bitcoin was introduced as the first cryptocurrency following the principle outlined by Satoshi Nakamoto in the paper “Bitcoin: A Peer-to-Peer Electronic Cash System.” The project was described as an electronic payment system using cryptographic proof instead of trust. It also mentioned using cryptographic proof to verify and record transactions o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decentralized Finance
Decentralized finance (often stylized as DeFi) provides financial instruments and services through smart contracts on a programmable, permissionless blockchain. This approach reduces the need for intermediaries such as brokerages, exchanges, or banks. DeFi platforms enable users to lend or borrow funds, speculate on asset price movements using derivatives, trade cryptocurrencies, insure against risks, and earn interest in savings-like accounts. The DeFi ecosystem is built on a layered architecture and highly composable building blocks. While some applications offer high interest rates, they carry high risks. Coding errors and hacks are a common challenge in DeFi. DeFi protocols exhibit varying degrees of decentralization, with truly decentralized protocols potentially acting as neutral infrastructure, while false decentralization leaves protocols open to manipulation and fraud or to being regulated as financial intermediaries.

Cardano (blockchain Platform)
Cardano is a public decentralized blockchain platform which uses the cryptocurrency, ADA, to facilitate transactions. Cardano's development began in 2015. When launched in 2017, it was the largest cryptocurrency to use a proof of stake blockchain. A number of independent entities collaborate on the project, including the Cardano Foundation based in Zug, Switzerland and led by its chief executive officer Frederik Gregaard. History After leaving Ethereum in 2014, Charles Hoskinson and Jeremy Wood set out their plans for establishing 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. Wood and Hoskinson co-founded the business IOHK to develop blockchains for use by corporations, governments, and education institutions. Cardano was initially released to the public in 2017. That year, IOHK partnered with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethereum
Ethereum is a decentralized blockchain with smart contract functionality. Ether (abbreviation: ETH) is the native cryptocurrency of the platform. Among cryptocurrencies, ether is second only to bitcoin in market capitalization. It is open-source software. Ethereum was conceived in 2013 by programmer Vitalik Buterin. Other founders include 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 decentralized applications onto it, with which users can interact. Decentralized finance (DeFi) applications provide financial instruments that do not directly rely on financial intermediaries like brokerages, exchanges, or banks. This facilitates borrowing against cryptocurrency holdings or lending them out for interest. Ethereum also allows users to create and exchange non-fungible tokens (NFTs), which are tokens that can be tied to un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blockchain
The blockchain is a distributed ledger with growing lists of Record (computer science), records (''blocks'') that are securely linked together via Cryptographic hash function, cryptographic hashes. Each block contains a cryptographic hash of the previous block, a Trusted timestamping, timestamp, and transaction data (generally represented as a Merkle tree, where Node (computer science), data nodes are represented by leaves). Since each block contains information about the previous block, they effectively form a ''chain'' (compare linked list data structure), with each additional block linking to the ones before it. Consequently, blockchain transactions are resistant to alteration because, once recorded, the data in any given block cannot be changed retroactively without altering all subsequent blocks and obtaining network consensus to accept these changes. Blockchains are typically managed by a peer-to-peer, peer-to-peer (P2P) computer network for use as a public distributed led ...

White Paper
A white paper is a report or guide that informs readers concisely about a complex issue and presents the issuing body's philosophy on the matter. It is meant to help readers understand an issue, solve a problem, or make a decision. Since the 1990s, this type of document has proliferated in business. Today, a business-to-business (B2B) white paper falls under grey literature, more akin to a marketing presentation meant to persuade customers and partners, and promote a certain product or viewpoint. The term originated in the 1920s to mean a type of position paper or industry report published by a department of the UK government. Corporate and academic The most prolific publishers of white papers are corporate and academic organizations. In larger organizations, internal technical writers produce these documents based on the outlines and data an internal industry or academic expert develops and provides. White papers often follow strict industry styles and formats with a centr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peer-to-peer Network

The components of a distribu ... architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the network, forming a peer-to-peer network of Node (networking), nodes. In addition, a personal area network (PAN) is also in nature a type of Decentralized computing, decentralized peer-to-peer network typically between two devices. Peers make a portion of their resources, such as processing power, disk storage, or network bandwidth, directly available to other network participants, without the need for central coordination by servers or stable hosts.

Application Software
Application software is any computer program that is intended for end-user use not operating, administering or programming the computer. An application (app, application program, software application) is any program that can be categorized as application software. Common types of applications include word processor, media player and accounting software. The term ''application software'' refers to all applications collectively and can be used to differentiate from system and utility software. Applications may be bundled with the computer and its system software or published separately. Applications may be proprietary or open-source. The short term ''app'' (coined in 1981 or earlier) became popular with the 2008 introduction of the iOS App Store, to refer to applications for mobile devices such as smartphones and tablets. Later, with introduction of the Mac App Store (in 2010) and Windows Store (in 2011), the term was extended in popular use to include desktop a ...

Icarus Bitcoin Mining Rig
In Greek mythology, Icarus (; , ) was the son of the master craftsman Daedalus, the architect of the labyrinth of Crete. After Theseus, king of Athens and enemy of King Minos, escaped from the labyrinth, Minos suspected that Icarus and Daedalus had revealed the labyrinth's secrets and imprisoned them—either in a large tower overlooking the ocean or in the labyrinth itself, depending upon the account. Icarus and Daedalus escaped using wings Daedalus constructed from birds’ molted feathers, threads from blankets, the leather straps from their sandals, and beeswax. Before escaping, Daedalus warned Icarus not to fly too low or the water would soak the feathers and not to fly too close to the sun or the heat would melt the wax. Icarus ignored Daedalus's instructions to not to fly too close to the sun, causing the beeswax in his wings to melt. Icarus fell from the sky, plunged into the sea, and drowned. The myth gave rise to the idiom, " fly too close to the sun." In some version ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solana (blockchain Platform)
Solana is a blockchain platform which uses a proof-of-stake mechanism to provide smart contract functionality. Its native cryptocurrency is SOL. Solana was launched in 2020 by Solana Labs, which was founded by Anatoly Yakovenko and Raj Gokal in 2018.
