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] |
Cryptocurrency Exchange
A cryptocurrency exchange, or a digital currency exchange (DCE), is a business that allows customers to trade cryptocurrencies or digital currencies for other assets, such as conventional fiat money or other digital currencies. Exchanges may accept credit card payments, wire transfers or other forms of payment in exchange for digital currencies or cryptocurrencies. A cryptocurrency exchange can be a market maker that typically takes the bid–ask spreads as a transaction commission for its service or, as a matching platform, simply charges fees. Some brokerages which also focus on other assets such as stocks, let users purchase but not withdraw cryptocurrencies to cryptocurrency wallets while dedicated cryptocurrency exchanges do allow cryptocurrency withdrawals. Operation A cryptocurrency exchange can typically send cryptocurrency to a user's personal cryptocurrency wallet. Some can convert digital currency balances into anonymous prepaid cards which can be used to withdraw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adam Draper
Adam is the name given in Genesis 1–5 to the first human. Adam is the first human-being aware of God, and features as such in various belief systems (including Judaism, Christianity, Gnosticism and Islam). According to Christianity, Adam sinned in the Garden of Eden by eating from the tree of the knowledge of good and evil. This action introduced death and sin into the world. This sinful nature infected all his descendants, and led humanity to be expelled from the Garden. Only through the crucifixion of Jesus, humanity can be redeemed. In Islam, Adam is considered ''Khalifa'' (خليفة) (successor) on earth. This is understood to mean either that he is God's deputy, the initiation of a new cycle of sentient life on earth, or both. Similar to the Biblical account, the Quran has Adam placed in a garden where he sins by taking from the Tree of life (Quran), Tree of Immortality, so loses his abode in the garden. When Adam repents from his sin, he is forgiven by God. This is see ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bitwise
In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits. It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor. Most bitwise operations are presented as two-operand instructions where the result replaces one of the input operands. On simple low-cost processors, typically, bitwise operations are substantially faster than division, several times faster than multiplication, and sometimes significantly faster than addition. While modern processors usually perform addition and multiplication just as fast as bitwise operations due to their longer instruction pipelines and other architectural design choices, bitwise operations do commonly use less power because of the reduced use of resources. Bitwise operators In the explanations below, any indication of a bit's position is counted from the right (least sig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zcash
Zcash is a privacy-focused cryptocurrency based on Bitcoin's codebase. It shares many similarities, such as a fixed total supply of 21 million units. Transactions can be transparent, similar to bitcoin transactions, or they can be shielded transactions which use a type of zero-knowledge proof to provide anonymity in transactions. Zcash coins are either in a transparent pool or a shielded pool. Zcash offers private transactors the option of "selective disclosure," allowing users to prove payment for auditing purposes. One such reason is to make it easier for private transactors to comply with anti-money laundering laws and tax regulations. Use Zcash transactions can be transparent, similar to bitcoin transactions, in which case they are controlled by a "t-addr" or shielded and controlled by a "z-addr." A shielded transaction uses a type of zero-knowledge proof, specifically a non-interactive zero-knowledge proof, called "zk-SNARK," which provides anonymity to the coin hold ...

Bitcoin Cash
Bitcoin Cash (also referred to as Bcash) is a cryptocurrency that is a fork of bitcoin. Launched in 2017, Bitcoin Cash is considered an altcoin or spin-off of bitcoin. In November 2018, Bitcoin Cash further split into two separate cryptocurrencies: Bitcoin Cash (BCH) and Bitcoin Satoshi Vision (BSV). History Since its inception, bitcoin users maintained a common set of rules for the cryptocurrency. On 21 July 2017, bitcoin miners implemented a software upgrade known as Bitcoin Improvement Proposal (BIP) 91, which activated the Segregated Witness (SegWit) upgrade at block 477,120. SegWit was a contentious update as it enabled second-layer solutions on bitcoin, such as the Lightning Network. A group of bitcoin activists, developers, and China-based miners opposed the proposed SegWit upgrades designed to increase bitcoin's capacity; these stakeholders pushed forward alternative plans which would increase the block size limit to eight megabytes through a hard fork.
