In fact, Bitcoin, invented by Satoshi Nakamoto a pseudonym , is both a virtual currency but convertible into dollars, euros and a secure exchange protocol like BitTorrent, which allows peer-to-peer file exchange. На самом деле, Bitcoin, изобретенный Сатоши Накамото псевдоним , сразу является виртуальной валютой но конвертируемой в баксы, евро Сатоши Накамото псевдоним , сразу является виртуальной валютой но конвертируемой в баксы, евро Well, in , the financial industry crashed and, perhaps propitiously, an anonymous person or persons named Satoshi Nakamoto created a paper where he developed a protocol for a digital cash that used an underlying cryptocurrency called Bitcoin.

В году во время краха денежной промышленности - и, может быть, чрезвычайно кстати - никому не узнаваемый Сатоши Накамото сделал документ - протокол для цифровой валюты с внедрением базисной криптовалюты, названной Биткойн. Эта криптовалюта дозволила обеспечить надёжность и оперировать без посредников. Сатоши Накамото сделал документ - протокол для цифровой валюты с внедрением базисной криптовалюты, названной Биткойн. In , a mysterious figure who wrote under the name Satoshi Nakamoto released a proposal for bitcoin.

В году некто узнаваемый под именованием Сатоси Накамото англ. Satoshi Nakamoto опубликовал описание системы Биткойн. Сатоси Накамото англ. It was founded in by this anonymous programmer using a pseudonym Satoshi Nakamoto. Онa была сотворена в году анонимным программистoм под псевдонимoм Сатоси Накамото. Никто не знает, кто он таковой. Проведенный доктором текстологический анализ показал, что больше всего на Накамото похож Кинг.

Она нашла несколько человек - к примеру, дизайнера мужской одежды из Нью-Йорка. За две недельки до встречи Гудман переписывалась с Накамото по электронной почте - выяснилось, что тот с юношества интересуется моделями поездов, движением которых можно управлять с компа. Накамото брал детали поездов в Стране восходящего солнца и Англии. Управление просит математических возможностей, которыми владеет Накамото и вся его семья: три его старшие брата работают инженерами, а сам Накамото окончил Политехнический институт Калифорнии как физик.

Правда, в отличие от братьев, Накамото так и не сумел сделать карьеру. Журналистка Newsweek попробовала обсудить по почте Bitcoin, но Накамото не стал отвечать. А когда она приехала к нему домой, он поначалу вызвал полицию. Позже произнес ей, что Bitcoin был передан «другим людям» и что он сам больше к этому дела не имеет. А брат Сатоши Артур охарактеризовал Накамото как блестящего математика, физика, инженера. Также Артур Накамото поведал, что его брат работал над скрытыми вещами и что он никода не признается в том, что имеет отношение к Bitcoin.

Bitcoin - на сто процентов виртуальная криптовалюта, не имеющая одного валютного центра. Накамото в г.

Mining in Bitcoin is really the commitment of a certain amount of computing resources to the sole purpose of solving computationally hard problems and validating new blocks. PoW enables Bitcoin to be both fully decentralized and fully secure. Anyone can participate in the mining process, without needing to own a certain number of bitcoin beforehand in order to do so.

In fact, it is completely unknown who the winner of the next mining reward will be at any given point in time, with additional computing power only serving to increase the probability that an individual node will be successful. Furthermore, the mining process also incentivizes nodes to act honestly because of the rewards associated with broadcasting the correct block.

Nakamoto Consensus places a large emphasis on the longest chain, arguing that the longest chain that is also valid according to timestamps none of the blocks are invalid due to double-spent transactions, for example is the most legitimate, as it had the largest amount of computational resources dedicated to it. This introduces trust in an otherwise trustless system, thus allowing the Bitcoin network to function without a centralized authority. For example, if a participant has been inactive, or has newly joined, they can simply accept the current longest chain as proof of what happened previously within the network.

They do not need to rely on a third party or some sort of establishment; rather, they simply start to build upon the longest valid chain, thus gaining the ability to receive rewards by proposing a computationally valid block. It allowed participants to have confidence in the network, and also set a standard through which miners could begin to join and leave at will without having to defer to an authority.

The longest chain rule has been adopted by numerous digital asset systems and blockchains that came after Bitcoin. Nakamoto Consensus ultimately revolutionized both digital currency and modern cryptography by introducing a BFT solution that was scalable, thus allowing Bitcoin to succeed as a trustless peer-to-peer transaction system.

While the Nakamoto Consensus model has seen its fair share of criticism, largely due to its tendency to allow the chain to fork, it remains one of the most efficient and successful consensus mechanisms among decentralized networks. By attaching a scarce resource computing power to the blockchain, Nakamoto Consensus gives Bitcoin implicit value, security, and trust over other currency systems. This is a guest post by Archie Chaudhury.

Opinions expressed are entirely their own and do not necessarily reflect those of BTC Inc. Press Releases. In this paper, we propose a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions.

The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes. We define an electronic coin as a chain of digital signatures. Each owner transfers the coin to the next by digitally signing a hash of the previous transaction and the public key of the next owner and adding these to the end of the coin. A payee can verify the signatures to verify the chain of ownership. A common solution is to introduce a trusted central authority, or mint, that checks every transaction for double spending.

After each transaction, the coin must be returned to the mint to issue a new coin, and only coins issued directly from the mint are trusted not to be double-spent. The problem with this solution is that the fate of the entire money system depends on the company running the mint, with every transaction having to go through them, just like a bank. We need a way for the payee to know that the previous owners did not sign any earlier transactions.

The only way to confirm the absence of a transaction is to be aware of all transactions. In the mint based model, the mint was aware of all transactions and decided which arrived first. To accomplish this without a trusted party, transactions must be publicly announced [1] , and we need a system for participants to agree on a single history of the order in which they were received. The payee needs proof that at the time of each transaction, the majority of nodes agreed it was the first received.

The solution we propose begins with a timestamp server. A timestamp server works by taking a hash of a block of items to be timestamped and widely publishing the hash, such as in a newspaper or Usenet post []. The timestamp proves that the data must have existed at the time, obviously, in order to get into the hash. Each timestamp includes the previous timestamp in its hash, forming a chain, with each additional timestamp reinforcing the ones before it.

The proof-of-work involves scanning for a value that when hashed, such as with SHA, the hash begins with a number of zero bits. The average work required is exponential in the number of zero bits required and can be verified by executing a single hash. Once the CPU effort has been expended to make it satisfy the proof-of-work, the block cannot be changed without redoing the work. As later blocks are chained after it, the work to change the block would include redoing all the blocks after it.

The proof-of-work also solves the problem of determining representation in majority decision making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote.

The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. If a majority of CPU power is controlled by honest nodes, the honest chain will grow the fastest and outpace any competing chains. To modify a past block, an attacker would have to redo the proof-of-work of the block and all blocks after it and then catch up with and surpass the work of the honest nodes.

We will show later that the probability of a slower attacker catching up diminishes exponentially as subsequent blocks are added. To compensate for increasing hardware speed and varying interest in running nodes over time, the proof-of-work difficulty is determined by a moving average targeting an average number of blocks per hour. Nodes always consider the longest chain to be the correct one and will keep working on extending it. If two nodes broadcast different versions of the next block simultaneously, some nodes may receive one or the other first.

In that case, they work on the first one they received, but save the other branch in case it becomes longer. The tie will be broken when the next proof-of-work is found and one branch becomes longer; the nodes that were working on the other branch will then switch to the longer one. New transaction broadcasts do not necessarily need to reach all nodes.

As long as they reach many nodes, they will get into a block before long. Block broadcasts are also tolerant of dropped messages. If a node does not receive a block, it will request it when it receives the next block and realizes it missed one. By convention, the first transaction in a block is a special transaction that starts a new coin owned by the creator of the block.

This adds an incentive for nodes to support the network, and provides a way to initially distribute coins into circulation, since there is no central authority to issue them. The steady addition of a constant of amount of new coins is analogous to gold miners expending resources to add gold to circulation. In our case, it is CPU time and electricity that is expended.

The incentive can also be funded with transaction fees. If the output value of a transaction is less than its input value, the difference is a transaction fee that is added to the incentive value of the block containing the transaction.

Once a predetermined number of coins have entered circulation, the incentive can transition entirely to transaction fees and be completely inflation free. The incentive may help encourage nodes to stay honest. If a greedy attacker is able to assemble more CPU power than all the honest nodes, he would have to choose between using it to defraud people by stealing back his payments, or using it to generate new coins. He ought to find it more profitable to play by the rules, such rules that favour him with more new coins than everyone else combined, than to undermine the system and the validity of his own wealth.

Once the latest transaction in a coin is buried under enough blocks, the spent transactions before it can be discarded to save disk space. Old blocks can then be compacted by stubbing off branches of the tree. The interior hashes do not need to be stored. A block header with no transactions would be about 80 bytes. It is possible to verify payments without running a full network node.

As such, the verification is reliable as long as honest nodes control the network, but is more vulnerable if the network is overpowered by an attacker. Businesses that receive frequent payments will probably still want to run their own nodes for more independent security and quicker verification.

Although it would be possible to handle coins individually, it would be unwieldy to make a separate transaction for every cent in a transfer. To allow value to be split and combined, transactions contain multiple inputs and outputs.
