Things you did not know about: Blockchain
Hello Steemians.
Today I want to share with you 10 things that maybe you did not know about the named technology: blockchain.
The term blockchain is being used since the emergence of bitcoin, the cryptocurrency that was born there in 2009. In fact, this currency is based on blockchain technology, which, broadly explained, would be a kind of public and shared large book in which All transactions that are made are reflected.
The blockchain system is a register of digital transactions that is based on a gigantic public database, protected and shared in which all the financial transactions carried out with the electronic currency are registered.
The blockchain database is made up of block chains that are duplicated in thousands of computers around the world. In addition, some blocks are linked with others, so it is not possible to modify something without the approval of some users called nodes, who are in charge of verifying that this transaction is correct and legitimate. Once something is modified, it is synchronized on all computers. Hence, this technology is difficult to hack.
For an operation to be incorporated into the database, it has to be validated by the network computers that perform mathematical calculations and update the registry continuously.
The coded and authenticated transaction blocks are added in chronological order in the numerical register, forming a chain of blocks, hence its name in English "blockchain".
I hope you liked my publication and that in my next post we know things you did not know about other topics.
Greetings.
