Bitcoin was introduced to the public on November 1st, 2008 with an email from Satoshi Nakamoto to the [email protected] mailing list:

I've been working on a new electronic cash system that's fully peer-to-peer, with no trusted third party.

The paper is available at:http://www.bitcoin.org/bitcoin.pdf

The main properties:
Double-spending is prevented with a peer-to-peer network.
No mint or other trusted parties.
Participants can be anonymous.
New coins are made from Hashcash style proof-of-work.
The proof-of-work for new coin generation also powers the network to prevent double-spending.

Bitcoin: un système de trésorerie électronique de pair à pair

Abstract. A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without the burdens of going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work. The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power. As long as honest nodes control the most CPU power on the network, they can generate the longest chain and outpace any attackers. The network itself requires minimal structure. Messages are broadcasted on a best effort basis, and nodes can leave and rejoin the network at will, accepting the longest proof-of-work chain as proof of what happened while they were gone.

Satoshi Nakamoto

The resulting thread saw some insightful analysis by Hal Finney, James A. Donald, and others on the email list. Satoshi also revealed something of 'his' motivations by saying that while Bitcoin wouldn't solve the world's political problems, "we can win a major battle in the arms race and gain a new territory of freedom for several years".

Prior to that first email, nothing is known of the genesis of the Bitcoin idea. Satoshi Nakamoto is a pseudonym, used by an individual or a group to protect their identity. The protocol has precedents in prior e-cash attempts, like Wei Dai's "B-money".

Two months later, the official Block 0 was mined, and Satoshi posted to the crypto list again to announce the open-source release of the first Bitcoin client.

Hal Finney decided it would be an excellent idea to get some retirement money after he’s unfrozen.

I mean, face it. You’re going to be iced soon, you can’t guarantee how the future is going to be like. Will there be banks? Will those white glove crooks keep your accounts while you’re “technically” dead? The first you don’t know, the second is a rotund no. They’re going to pillage you like any other “pensioner”.

The smartest thing you could do is to build some energetically inefficient payment network and deflationary speculative asset. Burning things won’t matter in the future1.

If you hype it enough and add some fallacies2, hardcore libertarians won’t be able to see through the cracks and will use it as flag in their eternal war against the state.

If you manage to get some early adopters in your bandwagon, there will be enough resistance to drop your coins in a hard fork.

What if someone finds out what you did? Easy, blame your neighbor!

Why would he care? Free food at parties, magazine covers, fame. And he can totally say he hasn’t got those coins!

Even if he takes the blame or not, there’s always going to be some crazy attention whore with issues™ around claiming to be you.

It don’t matter, he won’t be around when you’re unfreezed! Better hold on to that brain wallet! Hope vitrification does not ruin those pathways. Tattoos should hold too. You’ll be the richest mummy ever!

The concept of Bitcoin was invented by someone known as Satoshi Nakamoto. No one knows if this is his real name, whether its one person or a group, whether male or female. Whomsoever he might be, his concept was why do we have to involve a third party while carrying a financial transaction. Third party could be a bank, financial institution or a government. Satoshi wanted to have a financial system independent of these third parties. He developed this digital currency Bitcoinin 2008 and uploaded Bitcoin software in open source in 2009. Open source meant that Bitcoin is decentralised and there is no owner of this software. Refer link: Bitcoin - What is a Bitcoin | information about bitcoin .

Réponse d'origine: How was the first Bitcoin created?

Salut les gars,

The first miner of bitcoin was none other than Mr.Satoshi Nakamoto,

the master brain behind the concept bitcoin.

  • Of course, Bitcoins are assembled in blocks on the blockchain-automatic triple-entry ledger.
  • Bloc de la Genèse is termed as the very first block but it cannot be spent in any ways.
  • Satoshi mined & owns bitcoins from dozens of the first blocks in the blockchain.
  • This block contained only one single transaction, the ‘block reward’, assigning Bitcoins 50 to a newly created bitcoin address.

Best Wishes…..

Réponse d'origine: How was cryptocurrency (Bitcoin) created?

7 novembre 2008 (The Cryptography Mailing List): "Yes, [we will not find a solution to political problems in cryptography,] but we can win a major battle in the arms race and gain a new territory of freedom for several years. Governments are good at cutting off the heads of a centrally controlled network like Napster, but pure P2P networks like Gnutella and Tor seem to be holding their own."

Satoshi used Visual C++ (6.0) which he probably had installed in an offline computer that was not connected to the internet. He must have been doing programming experiments in C++ since the 90's. He mastered the STL and also had a good knowledge of Boost libraries which were fundamental and decisive for him to bring into fruition the data structures and algorithms he vaguely had in mind and that become to be more clear and real as he started to craft them.
The mastery of STL was very important for is initial coding. It was a fundamental part of the coding without which would make it much harder for him in terms of coding.
He then probably studied some p2p software like bittorrent. Probably one that was open source. He clearly had also an interest in GNU/Linux, and even the name 'bitcoin' suggests a connection on that territory.

I don't think he is a cryptographer with significant mathematical contribuitions. Meanwhile his mathematical intuition and outsider grasp into cryptography and its math is certainly above average.

Réponse d'origine: How was the first Bitcoin created?

Bitcoins are created in “blocks” on the blockchain, the massive, automatic triple-entry ledger that creates the security model of Bitcoin. The very first block is called the “genesis block” and was hand-coded by Satoshi, and is a required part of every version of the full client. The bitcoins in the genesis block cannot actually be spent, but Satoshi mined & owns bitcoins from dozens of the first blocks in the blockchain; and last I checked, he has never spent any of the coins connu to be his.
