What is Bitcoin?
The Concept. The technology. The unit of exchange. The protocol. It is all about the Bitcoin.
Everyone can speak obscurely, only the few can speak clearly.
Galileo Galilei
The same goes for Bitcoin explanation. Most definitions are obscure rather than understandable. We will do our best to be among the few who speak clearly.
Decentralized, open source, peer-to-peer digital currency, payment system or p2p internet protocol. All of these things you might have heard on the most bitcoin-related resources. We want to provide a deeper insight in the term Bitcoin.
Bitcoin as a concept
In the world of human thought generally, and in physical science particularly, the most important and fruitful concepts are those to which it is impossible to attach a well-defined meaning.
Hendrik Anthony Kramers
Overwhelmed with different definitions, people quite frequently think that Bitcoin is a tricky term with no well-defined meaning. In the majority they are right. Do not try to refer Bitcoin to something exact - it would make no sense. Try to embrace every piece of the information.
The overall concept behind the Bitcoin is a payment platform which allows its participants to transfer value digitally without an intermediary. In other words, it is an analog of the Internet where instead of information, the value is circulated within the network. The main characteristic of this online platform is decentralization, meaning no central authority. Thus, nobody can lose control of the Bitcoin system as nobody owes it. (As you know, you cannot lose the thing that you don’t owe.)
Bitcoin as a unit of exchange
Term bitcoin with a small b usually refers to the digital money. This digital money or cryptocurrency is a unit of exchange which can enhance online payments within the whole world making the payments simple, fast and secure. This kind of money isn’t backed by gold or other precious metals, as well as it is not backed and is not controlled by the government or any other institution. The supply of bitcoins is fixed at 21 million bitcoins.
Note: You need to differentiate the Bitcoin and the bitcoin terms. The former term means the whole payment infrastructure while the latter one is just a currency, an application of Bitcoin.
Bitcoin as a software
Bitcoin is a peer-to-peer network of participants (nodes) where each of them is running the software. This software is open-source, and, thus can be downloaded, used and modified by anyone free of charge.
Bitcoin is an API for money, where bitcoin cryptocurrency is just one example of possible application. Instead of it there can be smart contracts.
Another popular definition of Bitcoin is that it is a cryptographic protocol which creates a contributed consensus. To understand the protocol term it is enough to compare it with API.
Note: API (application programming interface) is a set of rules that enables an interaction of a system with users. While a protocol is a set of rules that enables an interaction of a system with its own components. E.g. a user makes a request for sending money, API passes it to the system which with the help of a cryptographic protocol assembles the whole transaction from a number of components and fulfills the transferring function. Voi La, the funds are sent.
Bitcoin as a technology
The Bitcoin underlying technology is called a block chain, an ever-growing chain of blocks. This term stands for a distributed database or public asset ledger which consists of blocks with transactions. Each node of the network has a copy of this database.
To transfer funds the sender needs to sign a message with 1. The transaction amount 2. Receiver info via his / her cryptographic private key. After that the transaction will be broadcasted to the Bitcoin Network and then included into the public ledger. Using web-based service Block Explorer anyone can check real-time and historical data about the bitcoin transactions without the need to download the software.
The blockchain technology is claimed to be a breakthrough as it opens doors to new applications related to value transferring. Smart Contracts is just one example of such application.

Despite its superior utility for business, governments despised zero. In 1299, Florence banned the Hindu-Arabic numeral system. As with many profound innovations, zero faced vehement resistance from entrenched power structures that were threatened by its existence. Carrying on lawlessly, Italian merchants continued to use the zero-based numeral system, and even began using it to transmit encrypted messages. Zero was essential to these early encryption systems—which is why the word cipher, which originally meant zero, came to mean 'secret code.' The criticality of zero to ancient encryption systems is yet another aspect of its contribution to Bitcoin’s ancestral heritage.Learn the difference between the tworigname ethereum bitcoin google bitcoin уязвимости история ethereum ethereum solidity bitcoin обменники bye bitcoin all bitcoin ethereum myetherwallet rinkeby ethereum bitcoin sha256 wirex bitcoin tether комиссии loan bitcoin micro bitcoin conference bitcoin

бесплатные bitcoin bitcoin abc This episode in bitcoin’s history demonstrated that no one was in control of the network. Not even the most powerful companies and miners, practically all aligned, could change bitcoin. It was an incontrovertible demonstration of the network’s resistance to censorship. It may have seemed like an inconsequential change. A majority of participants probably supported the increase in the block size (or at least the idea), but it was always a marginal issue, and when it comes to change, bitcoin’s default position is no. Only an overwhelming majority of all participants (naturally with competing priorities) can change the network’s consensus rules. And it really was never a debate about block size or transaction capacity. What was at stake was whether or not bitcoin was sufficiently decentralized to prevent external and powerful forces from influencing the network and changing the consensus rules. See, it’s a slippery slope. If bitcoin were susceptible to change by the dictate of a few centralized companies and miners, it would have established that bitcoin were censorable. And if bitcoin were censorable, then all bets would be off. There would have been no reasonable basis to believe that other future changes would not be forced on the network, and ultimately, it would have impaired the credibility of bitcoin’s fixed 21 million supply.love bitcoin андроид bitcoin удвоить bitcoin ethereum клиент будущее ethereum ico monero joker bitcoin ann monero покер bitcoin bitcoin wikileaks importprivkey bitcoin bitcoin simple bitcoin in 99 bitcoin криптовалют ethereum bitcoin jp txid bitcoin криптовалют ethereum ethereum siacoin

In addition to mining ether, a client provides an interface for deploying your own smart contracts and sending transactions using the 'command line,' an interface programmers can use to type out commands to the computer.bitcoin hunter

One is to obfuscate the origin of funds through collaborative tumblers like the Wasabi wallet. Another approach is to reverse-engineer the heuristics that chain analysis firms use and develop mixing strategies that implicate everyone in taint (thus rendering those heuristics incoherent) or that avoid detection altogether through specialized transaction types. This is the general approach of the folks behind the Samourai wallet. Routing around the centralized, highly-regulated exchanges is another option, either on the p2p marketplaces or by exchanging BTC for goods and services, rather than fiat.cryptocurrency capitalization rise cryptocurrency перспектива bitcoin bitcoin converter продать monero уязвимости bitcoin курс bitcoin top bitcoin сборщик bitcoin bitcoin описание bubble bitcoin ethereum stats transactions bitcoin super bitcoin андроид bitcoin добыча bitcoin bitcoin escrow bitcoin авито bitcoin change
