What is Bitcoin?
Bitcoin is money no one can take without your permission. It cannot be inflated away or confiscated, because no one person, company, or government controls it.
Bitcoin is digital money governed by computer code running on thousands of computers across the world. This computer code is separately run by many thousands of disparate individuals and organizations. This distributed base of code and people is ultimately what gives bitcoin its strong assurances against seizure and inflation.
Bitcoin is the first money system ever created that has a monetary policy anyone can understand and rely on, because no individual or organization has the ability to change it. When Bitcoin was launched in 2009, its monetary policy was defined in its initial codebase as a fixed-supply of 21,000,000 bitcoins. Copies of this code are now running all over the world, working together to process bitcoin transactions every second of every day. Unlike every other digital money system, there is no central point of control that make changes to the money supply.
This distributed nature and fixed supply give bitcoin properties similar to gold, but in electronic, digital form. That makes it fit for the modern economy, and allows for other capabilities that are not possible with physical assets. One way to conceptualize bitcoin is as "digital gold", but there are many ways to think about bitcoin.
How Bitcoin is Different
Until Bitcoin, all electronic money and digital transactions had to be managed by some authority, be it a bank, company, or government. Someone always had to sit in the middle of your transaction, with the ability to approve or deny it, and the currency used always had to be controlled by a central issuer that fully controlled monetary policy (ie, usually a government currency like USD or EUR).
This is not the case with bitcoin. When you want to use it, you can connect your wallet software to the internet and let it talk to the bitcoin network as a whole. You do not need to "login" to any service or have someone else issue transactions on your behalf. Combined with bitcoin's algorithmic monetary policy, this means you fully control your bitcoin, and no one can interfere with your ability to use it, or inflate the value away through monetary policy.
Why Bitcoin Matters
A few of the implications of bitcoin's unique properties include:
Bitcoin is the first scarce digital asset. Until bitcoin, anything digital could be easily copied. Satoshi Nakamoto's solution to this "double spending problem" and related issues around distributing the initial money supply fairly, was a breakthrough in computer science.
Scarcity is a key property of money. Until bitcoin, money native to the internet was not possible. With digital scarcity, native digital money can exist. It's been said that "if the internet were a country, bitcoin would be its currency".
Bitcoin is an open protocol, like other foundations of the internet such as t*****/ip (internet data packets) and smtp (email). Open protocols often dominate indefinately once they achieve an initial critical mass, due to the network effects that build-up on top of them. Bitcoin as a protocol for digital money and store of value is likely no different.
A store of value that's purely digital has many advantages over physical counterparts. Bitcoin can be moved with ease across the world, verified as authentic immediately, and even encrypted and "backed-up" in a "brain wallet" (memorized key).
As scarce digital value with no middleman, bitcoin represents perhaps the only asset that can be completely owned, controlled, and transported without reliance on any 3rd party.
The combination of bitcoin's properties as "digital gold", its censorship resistance, and flexibility due to its digital nature make it a powerful tool for people to take direct control over their financial lives, and/or take refuge from inflationary central bank monetary policies. This is why some describe bitcoin as "a peaceful revolution".
Bitcoin (pre)History
With the rise of PCs and public-key cryptography in the late 1970s, people began to realize that a fully electronic currency, not controlled by any single entity, might be possible. For 30 years, various cryptographers and entrepreneurs launched attempts at such a currency, but never solved key engineering and incentives trade-offs necessary to make it work well.
This changed in late 2008 when Satoshi Nakamoto published the bitcoin whitepaper to a cryptography mailing list, and subsquently published the bitcoin code and launched the bitcoin network in early 2009. Satoshi's achievement was three decades in the making, melding ideas from many other digital currency attempts into one elegant system. For decades many suspected that if a natively-digital money system without central control could be made to work, it would grow and thrive; Bitcoin is proving that true.

инвестирование bitcoin tokens ethereum bitcoin транзакция Although it is possible to handle bitcoins individually, it would be unwieldy to require a separate transaction for every bitcoin in a transaction. Transactions are therefore allowed to contain multiple inputs and outputs, allowing bitcoins to be split and combined. Common transactions will have either a single input from a larger previous transaction or multiple inputs combining smaller amounts, and one or two outputs: one for the payment, and one returning the change, if any, to the sender. Any difference between the total input and output amounts of a transaction goes to miners as a transaction fee.bitcoin avto bitcoin anonymous equihash bitcoin прогноз ethereum qr bitcoin bitcoin trade бизнес bitcoin bitcoin wmx bitcoin робот

ethereum developer ethereum контракт fake bitcoin bitcoin основы ethereum twitter bitcoin спекуляция 4pda tether The main purpose of the blockchain is to allow fast, secure and transparent peer-to-peer transactions. It is a trusted, decentralized network that allows for the transfer of digital values such as currency and data.Bitcoin is an adaptive and evolving system; it is not static. No one controls the network and there are no leaders capable of forcing changes onto the network. It is decentralized at every layer, and as a result, it has shown to be immune to any type of attack. However, it is not just immune to attack or errors, bitcoin actually becomes stronger as: i) external forces attempt to influence or coopt the network; ii) as individuals within the network make errors; and, iii) as a very function of its volatility, which is often perceived to be a limiting, if not critical, flaw. As bitcoin survives shocks and as individuals learn from errors and adapt to its volatility, bitcoin becomes tangibly more reliable; its demonstration of resilience and immunity causes trust to be reinforced in the network, which increases adoption and makes bitcoin more resistant to future attack or individual errors. It is a positive, self-reinforcing feedback loop. With every failed attempt to coopt or coerce the network, the bitcoin protocol hardens and confidence increases. Every time bitcoin doesn’t die, that very event propels bitcoin forward, and in a fundamentally stronger state than previously existed.A Core Blockchain Developer designs the security and the architecture of the proposed Blockchain system. In essence, the Core Blockchain Developer creates the foundation upon which others will then build upon.переводчик bitcoin

The first miner to generate a hash that is smaller than a target set by the network 'finds' the new block, receives the block reward – currently 25 litecoin – and any transaction fees present in the block. Since there is no way to know what nonce will generate a below-target hash, miners' results are subject to two factors: luck, which is outside of their control; and computing power, which can be bought (or stolen).bitcoin hd arbitrage cryptocurrency фермы bitcoin ethereum пул bitcoin биткоин пополнить bitcoin bitcoin технология payza bitcoin ethereum news is bitcoin pplns monero bitcoin мастернода cryptocurrency wikipedia mini bitcoin bitcoin 99 github ethereum портал bitcoin wei ethereum bitcoin китай bitcoin монета обсуждение bitcoin ethereum хардфорк

bitcoin ann If we had access to a trustworthy centralized service, this system would be trivial to implement; it could simply be coded exactly as described, using a centralized server's hard drive to keep track of the state. However, with Bitcoin we are trying to build a decentralized currency system, so we will need to combine the state transition system with a consensus system in order to ensure that everyone agrees on the order of transactions. Bitcoin's decentralized consensus process requires nodes in the network to continuously attempt to produce packages of transactions called 'blocks'. The network is intended to produce roughly one block every ten minutes, with each block containing a timestamp, a nonce, a reference to (ie. hash of) the previous block and a list of all of the transactions that have taken place since the previous block. Over time, this creates a persistent, ever-growing, 'blockchain' that constantly updates to represent the latest state of the Bitcoin ledger.
