How does Bitcoin work?
Transactions, Blocks, Mining, and the Block Chain The bitcoin system, unlike the payment systems of the traditional banking system, is based on decentralized trust. Instead of trusting a central authority, in bitcoin, trust is gets as an emergent property of the interactions of different participants in the system bitcoin In this chapter, we will examine bitcoin from a high level with the tracking of just one transaction through the bitcoin system and we will see how it becomes "trusted" and accepted by the distributed consensus mechanism of bitcoin and is finally saved in the blockchain, the accounting book of all transactions.

Each example is based on a transaction made in the bitcoin network, simulating the interactions between users (Joe, Alice, Bob) sending funds from one portfolio to another. Following a transaction through of the bitcoin network and the chain of blocks, we will use a website block chain explorer to see each step. A block chain explorer is a web application that operates as a bitcoin search engine, which allows you to search for addresses, transactions and blocks and see the relationships and flows between them

First, you have to know that it is a currency, like the euro, which is used to exchange goods and services, until everything you can expect from a currency, but the big difference is that it is an electronic division It stands out for its efficiency, security and ease of exchange, but it is not tangible, it is virtual.

This digital currency is created based on the blockchain, that is, a sequence of codes whose conversion into a chain of blocks, which consists of a cryptographic variant of computer programs that makes it very safe and reliable.

Its biggest differentiating feature is that it has these qualities in which it is decentralized, so no one controls it, without having a central issuer like the dollars, in this way the cryptocurrency can be produced by people and companies around the world, dedicating great amount of resources to the mining of this through their computers.

Currently, it is the most used digital currency in the world and offers great reasons for positioning in this leadership and becoming increasingly popular. Both private users and sellers and business owners have known that it is important and have decided to use this monetary system.

Of course, this is a simple and clear process, at present, it is the sending of money to any part of the world, but this is a large number of intermediaries that this process involves, such as: commissions by bank transfer, commissions by accept or show credit or debit cards ...

With the system implemented by Bitcoin there are no intermediaries and the money is transferred directly from person to person, from buyer to seller or between individuals. This reduces the price of sending money and allows you to sell products or services at a more competitive price.

Another aspect to highlight of this electronic currency is that being a decentralized system, it is impossible for any other person or entity that does not have your credentials to reach your money. That translates into a few words that your bitcoins are yours and can not be frozen or hijacked. Probably, for many people this quality is the most remarkable in this economically unstable world: to really feel the owners of their capital.

It is a currency that lives between constant ups and downs of value, but that in its trajectory premiums the increase in value, which is why it has become a safe haven for all types of investors.

To invest in this currency we must know what we have to abide by, so we should be well informed of everything that favors or harms its value and for that it is best to go to specialized magazines.
