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.
bitcoin strategy Users have used various types of hardware over time to mine blocks. Hardware specifications and performance statistics are detailed on the Mining Hardware Comparison page.bitcoin автомат bitcoin алгоритм bitcoin регистрации hashrate ethereum bitcoin 999 Central banks create more and more money which causes savings to be perpetually devalued. The entire incentive structure of money is manipulated, including the integrity of the scorecard that tracks who has created and consumed what value. Value created today is ensured to purchase less in the future as central banks allocate more units of the currency arbitrarily. Money is intended to store value, not lose value and with monetary economics engineered by central banks, everyone is unwittingly forced into the position of taking risk as a means to replace savings as it is debased. The unending devaluation of monetary savings forces unwanted and unwarranted risk taking on to those that make up the economy. Rather than simply benefiting from risks already taken, everyone is forced to take incremental risk.сеть bitcoin bitcoin анонимность ethereum block pokerstars bitcoin programming bitcoin ethereum 1070 отзыв bitcoin keys bitcoin bitcoin tor rotator bitcoin exchanges bitcoin

Bitcoin is 'not actually usable' for retail transactions because of high costs and the inability to process chargebacks, according to Nicholas Weaver, a researcher quoted by Bloomberg. High price volatility and transaction fees make paying for small retail purchases with bitcoin impractical, according to economist Kim Grauer. However, bitcoin continues to be used for large-item purchases on sites such as Overstock.com, and for cross-border payments to freelancers and other vendors.store bitcoin bitcoin торрент

The hash function makes it impossible to predict what the output will be. So, miners guess the mystery number and apply the hash function to the combination of that guessed number and the data in the block. The resulting hash starts with a certain number of zeroes. There’s no way of knowing which number will work, because two consecutive integers will give wildly varying results. What’s more, there may be several nonces that produce the desired result, or there may be none. In that case, the miners keep trying but with a different block configuration.ico ethereum арестован bitcoin mine ethereum бумажник bitcoin cryptocurrency bitcoin loan invest bitcoin

If you use Bitcoin, every transaction is documented in the blockchain and the trail of transactions can be followed. With the introduction of a concept called ring-signatures, the CryptoNight algorithm was able to cut through that trail.bitcoin wm Verifies the validity of each transaction request (i.e. no one is trying to transfer ether out of an account they haven’t produced a signature for, the request is not malformed, etc.), and then executes the code of the request, altering the state of their local copy of the EVM. The miner awards the transaction fee for each such transaction request to their own account.lootool bitcoin

bitcoin сеть проект bitcoin bitcoin pizza monero cryptonote Mining is the process of creating a block of transactions to be added to the Ethereum blockchain. Miners essentially process pending transactions and are awarded block rewards in the form of Ether, the Ethereum network's native currency, for each block generated. Generating a block requires intensive computational work (or hashing power) due to the difficulty set by the Ethereum network protocol. This difficulty level is proportional to the total amount of computational power (also known as the total hashrate of the network) being used to mine Ethereum and serves as a way to secure the network from attacks as well as tuning the speed at which blocks (and block rewards) are generated. This system of using hashing power generated by costly computer hardware is known as Proof of Work (PoW).bitcoin moneybox bistler bitcoin bitcoin wordpress ферма bitcoin bitcoin xyz bitcoin banks ethereum plasma monero hardware основатель bitcoin 3 bitcoin bitcoin site monero spelunker

She may instead transfer this value by first entrusting her currency to a bank who promises to store and protect Alice's currency notes. The bank gives Alice a written promise (called a 'bank statement') that entitles her to withdraw the same number of currency bills that she deposited. Since the money is still Alice's, she is entitled to do with it whatever she pleases, and the bank (like most banks), for a small fee, will do Alice the service of passing on the currency bills to Bob on her behalf. This is done by Alice's bank by giving the dollar bills to Bob's bank and informing them that the money is for Bob, who will then see the amount the next time he checks his balance or receives his bank statement.bitcoin flip bitcoin info bitcoin lion
