Blockchain

Blockchain technology is used to store and send information about transactions concluded on the internet. These transactions are arranged in consecutive blocks of data. Each block contains information about a specific number of transactions.

After filling it with transaction information, another data block is created, followed by the next and next block. This creates a kind of chain (hence the name: blockchain is a block chain). A new block appears on average every 10 minutes. It may contain information about various transactions, e.g. commercial transactions, ownership status, shares, shares, electricity generation and the purchase or sale of currencies, including cryptocurrencies – electronic currencies.

The essence of blockchain is to maintain a joint and collective transaction accounting book, in digital form, scattered throughout the network, in the same copies. This book is a collection of all transactions carried out at the moment in blockchain. This technology is based on peer-to-peer networks without central computers, transaction management and verification systems. Any computer on the network can participate in transaction transmission and authentication. In the case of blockchain, these will be blocks within the transaction book. The book is open to everyone, but fully secured by complicated cryptographic tools against unauthorized access.

Thanks to this entry, transactions are public, available to everyone, but visible only under the user’s access rights. Their entire history, from the beginning of blockchain existence to today, can be reviewed and verified.

Currently, blockchain can be used to handle various transactions, but work is underway to use the block chain as an accounting book in banking, a document authentication system, a digital signature in state administration and a notary record. All these transactions can take place outside the system that has been functioning for centuries – without the participation of public trust institutions, directly between the parties to the transaction. You can store any type of transaction in blockchain data blocks. One of the applications is the cryptocurrencies mentioned for example Bitcoin.

Main relevant issues related to the Bitcoin cryptocurrency.

Bitcoin is a form of digital currency, created and stored electronically. Established in 2009, by its creator Mr. Satoshi Nakamoto. It was the first virtual payment method of this type in the world. Thanks to several important features, it is one of the largest financial innovations of recent years.

At the moment, due to the lack of bank intermediation in funds transfer, bitcoin is considered by many investors as a cheaper alternative, especially for larger amounts.

Two other important features of cryptocurrencies payment system are definetely security and anonymity. Information on transactions carried out using bitcoin is encrypted using a technology called “blockchain”. At the moment, its mode of operation and continuous verification seems to be virtually unbreakable. Creating an account in this cryptocurrency has no formal conditions and the accounts are anonymous. The only thing the user receives to the invoice is a 54-character login and password.

A huge advantages of this payment method are also the speed and ease in making the transfers online. In the process of transferring funds, the distance to the place where we send the money does not matter and the transaction is carried out without intermediaries. Bitcoin transfers have no restrictions in the form of weekdays or holidays, we can send funds 24 hours a day, 7 days a week. Transactions are approved almost every 10 minutes.

In comparison to traditional banks that have a centralized database system, information about the status of bitcoin accounts is simultaneously found in many places on earth in the same form. That makes it definetely more secure.

These factors as much as the fact that according to the assumptions, a limited amount of 21,000,000 bitcoins will be created by 2140 have largely influenced the popularity of bitcoin, which is reflected in its market value. At present, approximately 16,500,000 bitcoins have already been circulated, and the pace at which others will hit the market will slow down.

What is Bitcoin cryptocurrency and BTC exchange?

Bitcoin is a form of digital currency, created and stored electronically. Established in 2009, by its creator Mr. Satoshi Nakamoto. It was the first virtual payment method of this type in the world. Unlike traditional, physical currencies like euros or dollars, Bitcoin is not printed – it has no physical form. Instead, bitcoin is created by computer scientists around the world, using programs that solve mathematical problems.

Bitcoin becomes very popular exchange medium that we can pay for more and more products and services. Day by day we can hear that more institutions, stores and other companies are starting to accept bitcoin. It is also a currency that has no physical form and can be sent immediately to anywhere on earth. This has a lot of advantages compared to e.g. international bank transfers, where money has to go through several banks along the way, and thus be saved on several subsequent virtual account books.  

Banks are another significant difference between cryptocurrencies and physical cash. The central bank’s mission is to stabilize its own currency. It can increase the money supply, which we call ‘reprinting’ to cover government debts, thereby devaluing the currency. However, in the case of digital currency, there is no such thing as Bitcoin Bank that would also be its regulator. This is due to the fact that Bitcoin is a bank in its own right. The independent accounting book contains information about the ownership status of all users and the history of transactions between them. To open an account with cryptocurrency, just download the special application and generate a login and password. Each user’s account is completely anonymous and has no formal requirements.

Here the meaning of the term “crypto” is revealed to us, because the above-mentioned information is just encrypted inside bitcoin. The way encryption is done is a revolution in the field of information technology – it is called “Blockchain”.
