Can each Bitcoin and Satoshi be uniquely identified?


Each user of bitcoin need have at least one address to receive coins. I just created an address 18TGt8oGgLzkCpjxMbiRfvbDo9NqGisopp, which due to the properties of how it is generated, is presumed to be unique.

If someone sends me any bitcoin they will be taking a coin from an existing balance on THEIR account (another bitcoin address) which will need to be signed using their private key. Once the transaction has been broadcast to the network, it will eventually make it into a block which will allow you to then spend it by signing it over to someone else.

While balances are generally expressed to users in whole bitcoin units, or sub units such as bitmil, transactions are expressed in satoshis. For example, if you were to give me a 1 bitcoin tip for this awesome answer :P the transaction would be of 100000000 to 18TGt8oGgLzkCpjxMbiRfvbDo9NqGisopp.

What is Bitcoin?

Bitcoin is a consensus network that enables a new payment system and a completely digital money. It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. From a user perspective, Bitcoin is pretty much like cash for the Internet. Bitcoin can also be seen as the most prominent triple entry bookkeeping system in existence.

Bitcoin is the first implementation of a concept called "cryptocurrency", which was first described in 1998 by Wei Dai on the cypherpunks mailing list, suggesting the idea of a new form of money that uses cryptography to control its creation and transactions, rather than a central authority. The first Bitcoin specification and proof of concept was published in 2009 in a cryptography mailing list by Satoshi Nakamoto. Satoshi left the project in late 2010...

A bit of history - The Bitcoin was invented by a man (or a group) using the pseudonym of Satoshi Nakamoto and having stayed anonymous. Satoshi Nakamoto launched the first version of Bitcoin in 2008 and gradually let out to other developers contributing to the project Gavin Andresen and others. No one has had any contact with Satoshi Nakamoto since mid-2010.

Prerequisites for understanding - The Bitcoin protocol is mainly based on technologies available and used before his appearance including:

Asymmetric Cryptography: a very popular cryptographic technology that allows notably to identify the author of a message: Each user has a public key and a private key. He uses his private key (known only to him) to encrypt a message that can be decrypted using his public key so he can be identified as the author of the message.

Cryptographic Hash: Function that creates a short fingerprint of a message or file, unique and non-reversible. Bitcoin mining consists in...

What is 'Bitcoin'

Bitcoin is a digital currency created in 2009. It follows the ideas set out in a white paper by the mysterious Satoshi Nakamoto, whose true identity has yet to be verified. Bitcoin offers the promise of lower transaction fees than traditional online payment mechanisms and is operated by a decentralized authority, unlike government-issued currencies. Today's market cap for all bitcoin (abbreviated BTC or, less frequently, XBT) in circulation exceeds $7 billion.

There are no physical bitcoins, only balances kept on a public ledger in the cloud, that – along with all Bitcoin transactions – is verified by a massive amount of computing power. Bitcoins are not issued or backed by any banks or governments, nor are individual bitcoins valuable as a commodity. Despite its not being legal tender, Bitcoin charts high on popularity, and has triggered the launch of other virtual currencies collectively referred to as Altcoins.

Members of the Bitcoin community remain sceptical about Craig Wright's claim to be the mysterious creator of the digital currency.

At the Consensus 2016 conference in New York, attendees told the BBC they wanted to see more proof before they would be ready to believe the claims.

Mr Wright spoke to the BBC claiming he created the crypto-currency.

Gavin Andresen, chief scientist at the Bitcoin Foundation, has confirmed the claim.

Noisy method

Mr Andresen said he travelled to London to meet Mr Wright who showed him proof that he and Satoshi Nakamoto - the pseudonym adopted by Bitcoin's creator - were one and the same.

"He signed in my presence using the private key from block one, the very first mined Bitcoin block, on a computer that I am convinced had not been tampered with," he said.

Each key is a unique digital code that is linked to specific bitcoins.

But even he added: "It is impossible to prove something like that...

In the hours after Newsweek claimed to have discovered the identity of the mystery-shrouded creator of the bitcoin cryptocurrency — pointing fingers at a 64-year-old retired engineer named Dorian Satoshi Nakamoto — a gaggle of reporters showed up on the man’s lawn in Southern California. And when he hopped into a blue Toyota Prius with one reporter, the rest of them piled into their own cars and chased him through the streets of downtown Los Angeles, desperate to get the story behind the myth of bitcoin’s founding father.

But those at the heart of the bitcoin community responded quite differently. The lead developer of the software that drives the bitcoin system was angry that Newsweek had gone after this man and his family, publishing his license plate number and a photograph of his house, and many others agreed. Even before the Associated Press reported that Dorian Nakamoto had denied any involvement with the digital currency, the bitcoin faithful were sure that Newsweek...

For months now, August 1st has loomed large in the Bitcoin world. It’s like a crypto version of Y2K: Will Bitcoin fork? If so, into how many chains? Which chain(s) will survive? Will Bitcoin itself survive the potential chaos and confusion?

When the Segwit2x agreement locked in recently, many fears were relieved and observers felt that the crisis was over…or at least delayed. However, one of the potential forks—Bitcoin Cash—has announced that, regardless of Segwit2x being locked in, it will fork nonetheless on August 1st.

What is Bitcoin Cash? How does it differ from Bitcoin? And, more importantly for Dash users, how does Bitcoin Cash compare to Dash?

(Note: for this article, the new fork will be referred to as “Bitcoin Cash” and the existing chain will be referred to as “Bitcoin.” This is for the sake of ease of reading, and does not imply greater support for one or the other chain, nor does it exclude the possibility that the chain now known as “Bitcoin Cash”...

A cryptocurrency called bitcoin increasingly becomes a hot topic of conversation around the globe, on television or the Internet, and yet the very essence of this phenomenon is still far from being accepted common knowledge. So what actually is bitcoin, and what makes it a point of keen interest of several countries?

Bitcoin: An Introduction

To get a grasp of what bitcoin is all about let’s get a handle of its basics first – what is, exactly, this thing called cryptocurrency? To put it simply, what we call cryptocurrency is electronic payment means which do not involve neither physical objects of recognized monetary value nor virtual equivalents of the money gathered on accounts of actual banks. It is virtual money you can not touch or see that is distributed and operated on virtually, through the Internet.

Сharacteristics of Cryptocurrency

Cryptocurrency is decentralized; there is no single center to collect or process data on its operations,...

All withdrawal requests are processed and paid directly to your bitcoin wallet within 24 hours. Bitcoin is a payment system introduced as open-source software in 2009 by developer Satoshi Nakamoto. The payments in the system are recorded in a public ledger using its own unit of account, which is also called bitcoin. Payments work peer-to-peer without a central repository or single administrator, which has led the US Treasury to call bitcoin a decentralized virtual currency. Although its status as a currency is disputed, media reports often refer to bitcoin as a cryptocurrency...

As stated in our guide "What is Blockchain Technology?", there are three principal technologies that combine to create a blockchain. None of them are new. Rather, it is their orchestration and application that is new.

These technologies are: 1) private key cryptography, 2) a distributed network with a shared ledger and 3) an incentive to service the network’s transactions, record-keeping and security.

The following is an explanation of how these technologies work together to secure digital relationships.

Cryptographic keys

Two people wish to transact over the internet.

Each of them holds a private key and a public key.

The main purpose of this component of blockchain technology is to create a secure digital identity reference. Identity is based on possession of a combination of private and public cryptographic keys.

The combination of these keys can be seen as a dexterous form of consent, creating an extremely useful...

What is Bitcoin?

Bitcoin is a Cryptocurrency that was released back in 2009 by pseudonymous developer Satoshi Nakamoto. Bitcoin uses peer-to-peer technology to operate with no central authority or banks, managing transactions and the issuing of bitcoins is carried out collectively by the network. The network is maintained by the miners that in return get rewarded with the currency. Bitcoin is open-source and its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any of the older previous payment system like cash, cheque or credit cards.

What is Money and Why Does it Exist?

Money exists to facilitate trade. Through the centuries trade has become incredibly complex everyone trades with everyone worldwide. Trade is recorded in bookkeeping, this information is often...

It’s currently been almost 4 months since we launched our first Bitcoin Faucet. The first thing we did was download the Faucet Script (Faucet in a Box) from FaucetBox and installing it in our web servers. We chose THC Servers as our hosting provider since it had a rather good client services an the pricing was ok, but what made us finally choose them was that they accepted BTC for payments. Also, choosing a cool, unique and attractive domain was something we considered very important to position each Bitcoin Faucet with it’s own identity and brand.

The first thing we started working was with the design and template the site had, something very important since it would be what our users would mainly experience (besides taking some satoshi’s on the way out).

As you can see, throughout time our design for Fullbitcoins has changed considerably in very short time, and not only that but every week we have made minor changes throughout AB...

What is Bitcoin?

Bitcoin is a cryptocurrency and a payment system invented by an unidentified programmer, or group of programmers, under the name of Satoshi Nakamoto.

Bitcoin was introduced on 31 October 2008 to a cryptography mailing list, and released as open-source software in 2009. There have been various claims and speculation concerning the identity of Nakamoto, none of which are confirmed. The system is peer-to-peer and transactions take place between users directly, without an intermediary. These transactions are verified by network nodes and recorded in a public distributed ledger called the blockchain, which uses bitcoin as its unit of account. Since the system works without a central repository or single administrator, the U.S. Treasury categorizes bitcoin as a decentralized virtual currency. Bitcoin is often called the first cryptocurrency, although prior systems existed and it is more correctly described as the first decentralized digital currency....

Is Craig Wright really Satoshi Nakamoto, the anonymous creator of bitcoin? And if he is, what happens now that we know his identity?

Those were two of the biggest questions floating around this week at Coindesk’s Consensus, an annual gathering of some of the biggest names in digital currency. The three day conference kicked off in New York just as news reports circulated that Wright, an Australian computer scientist and business owner, had revealed himself as the creator of bitcoin. Though Wright had been suspected to be Nakamoto for some time, many observers doubted the claim, saying Wright has alternative motives for stepping forward. For his part, Wright says he’s in the process of providing “extraordinary proof” that he is bitcoin’s creator. (Update: Wright said today he won’t provide any further proof, saying he doesn’t “have the courage” to do so.)

The mystery of Satoshi Nakamoto has created an additional layer of intrigue around bitcoin, and publications...
