This involves funds so we have to consider the security of and let us protect our money as well through further reading on cryptocurrencies and blockchain. 

Overview on Blockchain 

This is in charge of securing digital records or electronic transactions stored in a shared database of a certain network so it means that this information is saved online. Here, data is collected in groups or blocks which are connected to another group with sets of data through cryptography, that’s why it is called a blockchain. For example, if a certain block of information is full, this will be closed and a new group will be opened but is chained to the previous one chronologically. 

It is usually used as a ledger for various transactions made in a digital format so, in cryptocurrency, it is decentralized which means that every user retains control. As for users, whatever information is saved cannot be modified so it’s irreversible. Once data was already entered, this will be saved and recorded permanently so that users can view transaction history. 

So the primary goal here which is to record and distribute information sent over the Internet without editing was reached. Again, once it was already saved in a ledger, you may not even delete or destroy the recorded transaction.  

Is it secured? 

I supposed this technology won’t last if we cannot trust its security and since it has always been reliable, it started involving cryptocurrency. Again, new blocks of data are chained at the end of the full block in a linear and chronological order only. This means that you cannot go back to the previous ones for modifications, though you can view these records at any time. 

This is possible because these blocks come with hash codes which are programs that convert digital information to characters – letters and numbers. After conversion, we cannot make modifications unless we get into the system and see what those characters are. But that’s not visible to us since what we can view is the actual information we saved. 


This is a form of digital currency –  see, that can be accessed through various platforms you may install on your smartphones or open in your browsers. The system applied is peer-to-peer which means that you are allowed to send and receive coins anywhere or anytime as long as you have funds in your wallet. By the way, all transactions made are encrypted for security purposes. 

The platforms use blockchains because your transactions are saved in a ledger whenever you transfer or receive funds. Every account holder will have a digital wallet so this is where cryptocurrency will come in or out. But before performing such transactions, you must first get the link or address of the specific wallet where your funds will go so without this, transfers won’t be successful.
