Bitcoin Scalability Problem
The Bitcoin scalability problem refers to the limited capability of the Bitcoin network to handle large amounts of transaction data on its platform in a short span of time. It is related to the fact that records (known as ''blocks'') in the Bitcoin blockchain are limited in size and frequency. Bitcoin's blocks contain the transactions on the bitcoin network. The on-chain transaction processing capacity of the bitcoin network is limited by the average block creation time of 10 minutes and the original block size limit of 1 megabyte. These jointly constrain the network's throughput. The transaction processing capacity maximum estimated using an average or median transaction size is between 3.3 and 7 transactions per second. There are various proposed and activated solutions to address this issue. Background The block size limit, in concert with the proof-of-work difficulty adjustment settings of bitcoin's consensus protocol, constitutes a bottleneck in bitcoin's transaction proce ...

List Of Bitcoin Forks
Bitcoin forks are defined variantly as changes in the protocol of the bitcoin network or as the situations that occur "when two or more blocks have the same block height". A fork influences the validity of the rules. Forks are typically conducted in order to add new features to a blockchain, to reverse the effects of hacking or catastrophic bugs. Forks require consensus to be resolved or else a permanent split emerges. Forks of the client software The following are forks of the software client for the bitcoin network: ; Bitcoin XT: A fork initiated by Mike Hearn. The current reference implementation for bitcoin contains a computational bottleneck. The actual fork was preceded by Mike Hearn publishing a ''Bitcoin Improvement Proposal'' (BIP 64) on June 10, 2014, calling for the addition of "a small P2P protocol extension that performs UTXO lookups given a set of outpoints." On December 27, 2014 Hearn released version 0.10 of the forked client XT, with the BIP 64 changes. It ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Development
Software development is the process of conceiving, specifying, designing, programming, documenting, testing, and bug fixing involved in creating and maintaining applications, frameworks, or other software components. Software development involves writing and maintaining the source code, but in a broader sense, it includes all processes from the conception of the desired software through to the final manifestation of the software, typically in a planned and structured process. Software development also includes research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products. Methodologies One system development methodology is not necessarily suitable for use by all projects. Each of the available methodologies are best suited to specific kinds of projects, based on various technical, organizational, project, and team considerations. Software development activities Identification of need The sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roger Ver
Roger Keith Ver (born 27 January 1979) is an early investor in Bitcoin, Bitcoin-related startups and an early promoter of Bitcoin. Ver has sometimes been referred to as "Bitcoin Jesus". He now primarily promotes Bitcoin Cash as Ver sees it as fulfilling the intended and original purpose of the "Bitcoin White Paper", first published in 2009 by Satoshi Nakamoto, in which Nakamoto referred to Bitcoin as a peer-to-peer electronic cash system. Born and raised in Silicon Valley, he sold fireworks on eBay and later pleaded guilty to a related felony charge. He served 10 months in prison then moved to Japan in 2005. He renounced his United States citizenship in 2014 after obtaining a Saint Kitts and Nevis passport. He went on to serve as CEO of Bitcoin.com. Personal life Ver was born in San Jose, California. He attended Valley Christian High School. He then attended De Anza College for a year, dropping out to pursue his business interests. He identifies as a libertarian, anarcho-capit ...

SegWit
Segregated Witness, or SegWit, is the name used for an implemented soft fork change in the transaction format of Bitcoin. The formal title "Segregated Witness (Consensus layer)" had Bitcoin Improvement Proposal number BIP141. The declared purpose was to prevent nonintentional bitcoin transaction malleability, allow optional data transmission, and to bypass certain protocol restrictions (such as the block size limit) with a soft fork. It was also intended to mitigate a blockchain size limitation problem that reduces bitcoin transaction speed. It does this by splitting the transaction into two segments, removing the unlocking signature ("witness" data) from the original portion and appending it as a separate structure at the end. The original section would continue to hold the sender and receiver data, and the new "witness" structure would contain scripts and signatures. The original data segment would be counted normally, but the "witness" segment would, in effect, be counted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bitcoin SV
Bitcoin Cash is a cryptocurrency that is a fork of Bitcoin. Bitcoin Cash is a spin-off or altcoin that was created in 2017. In November 2018, Bitcoin Cash split further into two cryptocurrencies: Bitcoin Cash and Bitcoin SV. History Since its inception, Bitcoin users had maintained a common set of rules for the cryptocurrency. On 21 July 2017, bitcoin miners locked-in a software upgrade referred to as Bitcoin Improvement Proposal (BIP) 91, which meant that the Segregated Witness upgrade would activate at block 477,120. Segwit controversially would enable second layer solutions on bitcoin such as the Lightning Network. A key difference of opinion between Bitcoin users was over the running of nodes. Bitcoin supporters wanted to keep blocks small so that nodes could be operated with less resources, while some large block supporters find it acceptable that (due to large block sizes), nodes might only be run by universities, private companies and nonprofits.

Dogecoin
Dogecoin ( or , Abbreviation: DOGE; sign: Ð) is a cryptocurrency created by software engineers Billy Markus and Jackson Palmer, who decided to create a payment system as a "joke", making fun of the wild speculation in cryptocurrencies at the time. It is considered both the first "meme coin", and, more specifically, the first "dog coin". Despite its satirical nature, some consider it a legitimate investment prospect. Dogecoin features the face of the Shiba Inu dog from the "doge" meme as its logo and namesake.''A History of Dogecoin'' . Dogecoin Analysis Report. Social Science Research Network (SSRN). Accessed December 28, 2017. It was introduced on December 6, 2013, and quickly developed its own |
Litecoin
Litecoin (Abbreviation: LTC; sign: Ł) is a decentralized peer-to-peer cryptocurrency and open-source software project released under the MIT/X11 license. Inspired by Bitcoin, Litecoin was among the earliest altcoins, starting in October 2011. In technical details, the Litecoin main chain shares a slightly modified Bitcoin codebase. The practical effects of those codebase differences are lower transaction fees, faster transaction confirmations, and faster mining difficulty retargeting. Due to its underlying similarities to Bitcoin, Litecoin has historically been referred to as the "silver to Bitcoin's gold."Ismail, Ashiana. "Permissioned blockchains for real world applications." PhD diss., 2020. In 2022, Litecoin added optional privacy features via soft fork through the MWEB ( MimbleWimble extension block) upgrade.

El Salvador
El Salvador (; , meaning " The Saviour"), officially the Republic of El Salvador ( es, República de El Salvador), is a country in Central America. It is bordered on the northeast by Honduras, on the northwest by Guatemala, and on the south by the Pacific Ocean. El Salvador's capital and largest city is San Salvador. The country's population in 2022 is estimated to be 6.5 million. Among the Mesoamerican nations that historically controlled the region are the Lenca (after 600 AD), the Mayans, and then the Cuzcatlecs. Archaeological monuments also suggest an early Olmec presence around the first millennium BC. In the beginning of the 16th century, the Spanish Empire conquered the Central American territory, incorporating it into the Viceroyalty of New Spain ruled from Mexico City. However the Viceroyalty of Mexico had little to no influence in the daily affairs of the isthmus, which was colonized in 1524. In 1609, the area was declared the Captaincy General of Guatemala by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Legal Tender
Legal tender is a form of money that courts of law are required to recognize as satisfactory payment for any monetary debt. Each jurisdiction determines what is legal tender, but essentially it is anything which when offered ("tendered") in payment of a debt extinguishes the debt. There is no obligation on the creditor to accept the tendered payment, but the act of tendering the payment in legal tender discharges the debt. Some jurisdictions allow contract law to overrule the status of legal tender, allowing (for example) merchants to specify that they will not accept cash payments. Coins and banknotes are usually defined as legal tender in many countries, but personal cheques, credit cards, and similar non-cash methods of payment are usually not. Some jurisdictions may include a specific foreign currency as legal tender, at times as its exclusive legal tender or concurrently with its domestic currency. Some jurisdictions may forbid or restrict payment made by other than legal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
