Unstoppable Domains
Unstoppable Domains is a private technology company based in San Francisco, California. Founded in 2018 by Matthew Gould, the company registers both traditional DNS domain names, and domains with endings like '.crypto', '.bitcoin' or '.wallet' that are built on blockchain networks. These blockchain domains can be used to receive cryptocurrency, access decentralized websites, and manage digital identities. Overview Unstoppable Domains manages domain names minted as non-fungible tokens (NFTs). These domains, often referred to as blockchain-based or NFT domains, function similarly to traditional web addresses, but are stored on public blockchains rather than managed by centralized authorities. Unlike traditional web domains, NFT domains incur a one-time purchase fee, with no annual renewal cost. They thus allow users to own their domain names outright. Unstoppable's NFT domains can be used to simplify crypto wallet addresses, host decentralized websites and to authenticate log- ...

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 ...

Bitcoin
Bitcoin (abbreviation: BTC; Currency symbol, sign: ₿) is the first Decentralized application, decentralized cryptocurrency. Based on a free-market ideology, bitcoin was invented in 2008 when an unknown entity published a white paper under the pseudonym of Satoshi Nakamoto. Use of bitcoin as a currency began in 2009, with the release of its open-source software, open-source implementation. In 2021, Bitcoin in El Salvador, El Salvador adopted it as legal tender. It is mostly seen as an investment and has been described by some scholars as an economic bubble. As bitcoin is pseudonymous, Cryptocurrency and crime, its use by criminals has attracted the attention of regulators, leading to Legality of cryptocurrency by country or territory, its ban by several countries . Bitcoin works through the collaboration of computers, each of which acts as a Node (networking), node in the peer-to-peer bitcoin network. Each node maintains an independent copy of a public distributed ledger of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

InterPlanetary File System
The InterPlanetary File System (IPFS) is a protocol, hypermedia and file sharing peer-to-peer network for sharing data using a distributed hash table to store provider information. By using content addressing, IPFS uniquely identifies each file in a global namespace that connects IPFS hosts, creating a distributed system of file storage and sharing. IPFS allows users to host and receive content in a manner similar to BitTorrent. As opposed to a centrally located server, IPFS is built around a decentralized system of user-operators who hold a portion of the overall data. Any user in the network can serve a file by its content address, and other peers in the network can find and request that content from any node who has it using a distributed hash table (DHT). In contrast to traditional location-based protocols like HTTP and HTTPS, IPFS uses content-based addressing to provide a decentralized alternative for distributing the World Wide Web.

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] |
