Bitcoin What is it? And is he really so anonymous?

Bitcoin
Today we’ll talk about the most popular currency of our days, Bitcoin, where it came from, how it works, why it is the top payment method used on the black market.

We also touch on the topic - why Bitcoin is not as anonymous as is commonly believed, and was never created for this.

I will not cover all aspects of his work and describe in detail its mechanism, because this requires more than one article, and many, in principle, do not really need to know this. So I will cover all the basic principles briefly.

Bitcoin? Who invented this game? I heard for him only spaysuha nariki and buy



In the first idea, Bitcoin was uploaded to the network by Satoshi Nakamoto in 2008. The purpose of creating Bitcoin was to solve the problem with the fact that all purchases on the Internet are somehow controlled by banks that charge a commission, while we must trust them, and if we add to this the issue of security of our funds ...

In general, Satoshi solved all these shortcomings and introduced a new digital currency, Bitcoin, which is decentralized, allows you to make payments quickly, is safe, can be used in any country, the account cannot be frozen and there are no regulations or restrictions on use, and the payment commission is negligible and moreover - You yourself can decide what commission you pay, or you can do without it at all.

I still do not understand anything. I translate with kiwi without commission.

Bitcoins are digital money that can be sent over the Internet; they do not have a physical medium like rubles or dollars.

But we all know that our usual currency requires the presence of gold, and hence its extraction. Bitcoin works according to a similar scheme, only mining of bitcoins, or in another way - mining, is due to computing resources. The process itself is difficult to explain in a nutshell, but if on the fingers - solving problems and performing computational processes, the miner receives bitcoins in exchange.



That is, you can become a billionaire simply by turning on the program on your computer?

No wonder I gave an example with gold. After all, gold is not infinite and the more we mine it, the more difficult it is to find. Bitcoin is exactly the same story. If earlier this process was simple, now it is more and more difficult to get it every day. Now, to get the normal number of bitcoins, you need investments in more than one million.

Bitcoin reserves are also limited by the creator of 21 million bitcoins. To date, more than 16 million have been mined.

But you can buy bitcoins. The price of bitcoin is always floating, but its growth cannot be denied.

2011 - $ 30
2016 - at the beginning of the year 400 dollars
2017 - in April, the cost is $ 1,190
2018 - in January - $ 14,576

History knows many cases when the price of bitcoins rose sharply and for which a year ago you could buy a croissant, now it was a fortune.

For example, many people know about the case when a guy bought pizza in 2010 for 10,000 bitcoins. Then it was 50 dollars. Now it's 140 million dollars.

Another “ingenious” character accidentally threw out a hard drive with wallet data in the amount of 7,500 bitcoins and tried to find it in a garbage dump the size of a football field.

So how is the money transfer system itself arranged?

All transfers are stored in one “account book”, but each of the users of the Bitcoin network has its own copy. That is, everyone knows about all transactions, this data is open. It seems that this already does not speak in favor of security, but not so simple.

For example, Fedya decided to list Vasya 1 bitcoin. For the transfer to come to Vasya, the data from the transaction must go through a certain number of nodes (other users) who update their “book” and transfer to another node.

To transfer funds, a digital signature is required, which is different for each transaction. The signature works on the basis of two keys - private and public. A signature creates a private key, and with the help of a public one, other people can verify the signature. To make it easier, the private key is the password, and the signature is the intermediary. A signature certifies the transaction and confirms that you know the private key.

The public key serves as the address to receive, that is, Fedya sending Vasya 1 bitcoin sends them to the public key.

This is only a micron fraction of the bitcoin system. But as promised - we are considering the base.

But what about anonymity?

To register in Bitcoin, you do not need to specify any personal data. You specify the master password for accessing the wallet, as well as a secret phrase by which you can access from new devices.

There are three main ways to reveal the identity of Bitcoin users.

1. First of all, although transactions are randomly transmitted through a P2P network, this system is not completely leakproof. If an attacker, for example, has the ability to connect several nodes to the Bitcoin network, the information gathered by them may be enough to determine the source of a particular transaction.

2. A Bitcoin address can be associated with specific people if their personal information was in any way connected with such a Bitcoin address. This includes addresses used to deposit or withdraw money from a regulated exchange or wallet, publicly available addresses for donations, or simply addresses used to send bitcoins using personal information (for example, payment in an online store).

3. All transactions in the Bitcoin network are completely transparent to anyone interested. This allows you to associate several bitcoin addresses and assign them to a specific user. Thus, if only one of these linked addresses is tied to a specific person in one of the above ways, all addresses will be deanonymized.

How can anonymity be maintained?

1. Create a new address for each new transaction
2. When using Bitcoin, connect through a bunch of vpn-tor-vpn
3. Use of mixers. Bitcoin mixer, accepts bitcoins to input addresses and sends back different bitcoins from input addresses. There are many types of mixers, but they are all similar in one: all users using the mixer get each other's bitcoins. A well-implemented “mixing” of bitcoins greatly complicates the analysis of transactional networks, as well as “distribution analysis”. To consolidate success, “mixing” can be done several times in a row.

But you should not be paranoid if you just make ordinary purchases. Moreover, you can use simply exchangers for withdrawal to regular currency and drive them into your new wallet.

Well, the answer to the question of why this is the top payment method on the black market, I think you already understand. This is security, the speed of translation without control, and if used correctly, it gives anonymity.

This is a small fraction of what can be said about this system. But the fact that she is brilliant is impossible to deny.

I like the ruble more, I think he will show himself

I agree!
