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 ...

Non-fungible Token
A non-fungible token (NFT) is a unique digital identifier that is recorded on a blockchain and is used to certify ownership and authenticity. It cannot be copied, substituted, or subdivided. The ownership of an NFT is recorded in the blockchain and can be transferred by the owner, allowing NFTs to be sold and traded. Initially pitched as a new class of investment asset, by September 2023, one report claimed that over 95% of NFT collections had zero monetary value. NFTs can be created by anybody and require little or no coding skill to create. NFTs typically contain references to digital files such as artworks, photos, videos, and audio. Because NFTs are uniquely identifiable, they differ from cryptocurrencies, which are fungible (hence the name non-fungible token). Proponents claim that NFTs provide a public certificate of authenticity or proof of ownership, but the legal rights conveyed by an NFT can be uncertain. The ownership of an NFT as defined by the blockchain has no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cryptocurrency
A cryptocurrency (colloquially crypto) is a digital currency designed to work through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it. Individual coin ownership records are stored in a digital ledger or blockchain, which is a computerized database that uses a consensus mechanism to secure transaction records, control the creation of additional coins, and verify the transfer of coin ownership. The two most common consensus mechanisms are proof of work and proof of stake. Despite the name, which has come to describe many of the fungible blockchain tokens that have been created, cryptocurrencies are not considered to be currencies in the traditional sense, and varying legal treatments have been applied to them in various jurisdictions, including classification as commodities, securities, and currencies. Cryptocurrencies are generally viewed as a distinct asset class in practice. The first cryptocu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Most Expensive Non-fungible Tokens
This is a list of the highest known prices possibly paid for non-fungible tokens (NFTs) representing digital assets. Background Monetization of digital assets as NFTs became possible with the release of Etheria, on the Ethereum blockchain, in 2015. From late 2017, the NFT market grew quickly. In the first three months of 2021, NFTs worth US$200 million were traded. One of the earliest NFT projects, CryptoPunks, has provided several of the most expensive NFTs. There were some NFT-like projects or "proto NFTs" that pre-date CryptoPunks; Rare Pepes, for example, was released on Counterparty in 2014. List of highest prices paid This list is ordered by consumer price index inflation-adjusted value (in bold) in millions of United States dollars in .The Wikipedia template uses a yearly average inflation. Using monthly averages gives slightly different numbers, most significantly for paintings sold early or late in a year with significant inflation. Where necessary, the price is first ...

CryptoPunks
''CryptoPunks'' is a non-fungible token (NFT) collection on the Ethereum blockchain. The project was launched in June 2017 by the Larva Labs studio, a two-person team consisting of Canadian software developers Matt Hall and John Watkinson. The experimental project was inspired by the London punk scenes, the cyberpunk movement, and electronic music artists Daft Punk. The crypto art blockchain project was an inspiration for the ERC-721 standard for NFTs and the modern crypto art movement, which has since become a part of the cryptocurrency and decentralized finance ecosystems on multiple blockchains. CryptoPunks are commonly credited with starting the NFT craze of 2021, along with other early projects including CryptoKitties, Bored Ape Yacht Club, and the sale of Beeple's ''Everydays: The First 5000 Days''. There are 10,000 CryptoPunk tokens total. On March 2, 2022, an anonymous user donated CryptoPunk #5364 to Ukraine's government Ethereum wallet public address to help fund t ...

Non-fungible Tokens
In economics and law, fungibility is the property of something whose individual units are considered fundamentally interchangeable with each other. For example, the fungibility of money means that a $100 bill (note) is considered entirely equivalent to another $100 bill, or to twenty $5 bills and so on, and therefore a person who borrows $100 in the form of a $100 bill can repay the money with another $100 bill, with twenty $5 bills and so on. Non-fungible items are not considered substitutable in the same manner, even if essentially identical. Fungibility is an important concept in finance and commerce, where financial securities, currencies and physical commodities such as gold and oil are normally considered fungible. Fungibility affects how legal rights, such as the ownership of assets in custody and the right to receive goods under a contract, apply in certain circumstances, and it thereby simplifies trading and custody. Fungibility refers only to the equivalence and in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
