wikipedia: Remittance

Money sent home by migrants competes with international aid as some of the largest financial inflows to developing countries. In 2012, according to the World Bank Report, $401 billion went to developing countries (a new record) with overall global remittances at $514 billion.[1] The economic impact remains contested among researchers,[2][3] however, remittance transfers do draw people towards the financial services that are available to them. [citation needed] Significance[edit] Remittances are playing an increasingly large role in the economies of many countries, contributing to economic growth and to the livelihoods of less prosperous people (though generally not the poorest of the poor).

The World Bank and the Bank for International Settlements have developed international standards for remittance services.[6] AndrewHires : Andreas M. Antonopoulos giving... Cryptocurrency. A cryptocurrency is a medium of exchange designed around securely exchanging information which is a process made possible by certain principles of cryptography.


The first cryptocurrency to begin trading was Bitcoin in 2009. Since then, numerous cryptocurrencies have been created. Fundamentally, cryptocurrencies are specifications regarding the use of currency which seek to incorporate principles of cryptography to implement a distributed, decentralized and secure information economy. Overview[edit] When comparing cryptocurrencies to fiat money, the most notable difference is in how no group or individual may accelerate, stunt or in any other way significantly abuse the production of money.

Most cryptocurrencies are designed to gradually introduce new units of currency, placing an ultimate cap on the total amount of currency that will ever be in circulation. Bitcoin 2.0 Explained: Colored Coins Vs Mastercoin Vs Open Transactions Vs Protoshares. While the entire world is beginning to learn about the power of the Bitcoin payment network, the real innovation behind this protocol is happening behind the scenes.

Bitcoin 2.0 Explained: Colored Coins Vs Mastercoin Vs Open Transactions Vs Protoshares

There have been many different Bitcoin enthusiasts who have been talking about the holy grail of decentralized exchanges and using the Bitcoin protocol for more than just payments, and it seems that 2014 is going to be the year when we see these features finally get implemented into some real world applications. There are many different projects that are currently aiming to take Bitcoin to the next level, and it's likely that there won't be one clear winner when everything is said and done. Before we hop into the competition, let's take a closer look at exactly what these projects are trying to accomplish. Decentralizing the Internet. Bitcoin creator Satoshi Nakamoto revealed after years of mystery. [UPDATE 4:15pm CT: Reporters across Los Angeles have been hounding the man Newsweek identified as Dorian Satoshi Nakamoto.

He told reporters gathered at his front door that he is "not involved with Bitcoin. " Andrea Chang, a Los Angeles Times reporter, said on Twitter that this Nakamoto later also denied having had any involvement with Bitcoin. We have a new story on Nakamoto's latest statements.] Would JPM's Dimon ever accept bitcoin? Bitcoin for Undergrads, Wall Street’s Next Pump-and-Dump. The story was everywhere last week: MIT undergraduates will each receive $100 in Bitcoin when they arrive on campus next fall.

Bitcoin for Undergrads, Wall Street’s Next Pump-and-Dump

The gift comes thanks to an affluent donor and two precocious student entrepreneurs — one a sophomore computer science major, the other a first-year Sloan MBA student and president of the MIT Bitcoin Club. I exaggerate slightly when I say the story was everywhere. As far as I know, Foreign Affairs hasn’t yet picked it up. But the Boston Globe, Boston Magazine, USA Today, Time, Vice, The Wire, Slate, the Guardian, the Independent, the Telegraph, the Christian Science Monitor, the Jewish Daily Forward, RT, public radio’s Marketplace, Reuters, and Bloomberg all did run with it, along with basically every tech blog (and there are way too many tech blogs). The coverage was predictably gee-whiz.

Follow The Bitcoins: How We Got Busted Buying Drugs On Silk Road's Black Market. Wikipedia, Bitcoin. Bitcoins are created as a reward in a competition in which users offer their computing power to verify and record bitcoin transactions into the blockchain.

This activity is referred to as mining and successful miners are rewarded with transaction fees and newly created bitcoins.[14]:5–7 Besides being obtained by mining, bitcoins can be exchanged for other currencies,[21] products, and services.[22] When sending bitcoins, users can pay an optional transaction fee to the miners.[23] This may expedite the transaction being confirmed. According to a research produced by Cambridge University in 2017, there are between 2.9 million and 5.8 million unique users actively using a cryptocurrency wallet, most of them using bitcoin. The number of active users has grown significantly since 2013 (there were 0.3 to 1.3 million unique users at the time).[28] Etymology and orthography. Wikipedia, History of Bitcoin.

wikipedia, History of Bitcoin

Bitcoin is the first cryptocurrency, a form of money that uses cryptography to control its creation and management, rather than relying on central authorities.[1] However, not all of the technologies and concepts that make up Bitcoin are new; the presumed pseudonym Satoshi Nakamoto (the creator of Bitcoin, see below) integrated many existing ideas from the cypherpunk community when creating Bitcoin. Pre-history[edit] Independently and at around the same time Wei Dai proposed b-money [3] and Nick Szabo proposed bit-gold.[4] Subsequently Hal Finney implemented and deployed RPOW a reusable form of hashcash based on IBM secure TPM hardware and remote attestation (centralized but with no issuer inflation risk). Creation[edit] Wikipedia, Satoshi Nakamoto. Satoshi Nakamoto (中本 哲史[1], Nakamoto Satoshi?)

wikipedia, Satoshi Nakamoto

Is a person or group of persons who created the Bitcoin protocol and reference software, Bitcoin Core. In 2008, Nakamoto published a paper[2][3] on The Cryptography Mailing list at[4] describing the Bitcoin digital currency. In 2009, he released the first Bitcoin software that launched the network and the first units of the Bitcoin currency, called bitcoins.[5][6] Nakamoto is said to have continued to contribute to his Bitcoin software release with other developers until contact with his team and the community gradually began to fade in mid-2010.

Near this time, he handed over control of the source code repository and alert key functions of the software to Gavin Andresen.[7] Also around this same time, he handed over control of the domain and several other domains to various prominent members of the Bitcoin community. Nakamoto is believed to be in possession of roughly one million bitcoins. Satoshi Nakamoto, bitcoin: A Peer-to-Peer Electronic Cash System. Satoshi Nakamoto, Satoshi Nakamoto's, p2p foundation. Wikipedia, Bitcoin protocol. The Bitcoin network is a peer-to-peer payment network that operates on a cryptographic protocol.

wikipedia, Bitcoin protocol

Users send bitcoins, the unit of currency, by broadcasting digitally signed messages to the network using Bitcoin wallet software. Transactions are recorded into a distributed public database known as the block chain, with consensus achieved by a proof-of-work system called "mining". The block chain is distributed internationally using peer-to-peer filesharing technology similar to BitTorrent. The protocol was designed in 2008 and released in 2009 as open source software by "Satoshi Nakamoto", the pseudonym of the original developer or group of developers. The network timestamps transactions by including them in blocks that form an ongoing chain called the block chain. The network itself requires minimal structure to share transactions. Bitcoin Escrow. Bitcoin Escrow Protocol., Contracts. A distributed contract is a method of using Bitcoin to form agreements with people via the block chain.

Contracts don't make anything possible that was previously impossible, but rather, they allow you to solve common problems in a way that minimizes trust. Minimal trust often makes things more convenient by allowing human judgements to be taken out of the loop, thus allowing complete automation. By building low trust protocols that interact with Bitcoin, entirely new products can be created: Smart property is property that can be atomically traded and loaned via the block chain.

Transferable virtual property are digital items that can be traded but not duplicated. This page also lists some smaller examples.
