Blockchain and bitcoin – why are they together?
Everything is very simple here: the blockchain technology and bitcoin were invented by the same person Satoshi Nakamoto. Well, okay, man – it’s loudly said. After all, the fact of the existence of such a character on planet Earth has not been proven.
It is generally accepted that it was Satoshi Nakamoto who came up with the bitcoin code and then implemented the database security technology. But here’s what this person’s real name is and what he looks like, no one knows for sure.
We have already written in more detail about bitcoin and what it is in one of the previous articles. The very concept of blockchain was introduced in 2009.
Blockchain for bitcoin looks like a common ledger of all data transactions. This gave bitcoin the opportunity to become the world’s first cryptocurrency.
Blockchain and bitcoin
What does the term “cryptocurrency” mean? This is nothing but the impossibility of double use of money. Unlike paper banknotes, electronic money can be used multiple times.
Why is this happening? A simple example. If you send a file from your computer to another user, then not the file itself is sent, but a copy of it. And it turns out that the same document is present on two devices at once. It is the same with electronic bank accounts.
If the blockchain is used in email technologies, then the transfer of documents and files will go without copying them, but with a direct transfer. That is, such a file will be automatically deleted on the sender’s computer.
