What is Blockchain ?
Blockchain is a technology that transfers these Bitcoin digital codes.
Blockchain is similar to our mobile banking remittance form. The difference is that ordinary mobile money transfers can be controlled and accessed from banks' data centers as needed. This type of control technology is called a centralized chain.
This is called central control because it stores the data of users' amount figures on the original server.
Blockchain does not store data in a database on a central server, but distributes users' data wherever there is an Internet connection and no one can control it.
Only one user can manage and transfer their digital code as needed. It will be acceptable. Data transferred by a user appears as a list on the Internet. This list is called a ledger or block. This is called a blockchain.
These transferred statistics blocks are displayed on the blockchain website for public viewing. You can see when, when and how much was transferred.
Blockchain has two parts.
Block + chain (Block is a record, chain is connected) Transfers can be easily made on regular servers. In the case of Blockchain, the transaction information is separated into individual blocks and the communication between the blocks is marked with a hash.
This hash connects the front block to the back block. If you add new information between these blocks, the connection between those hashes will be broken and the blockchain will stop. Therefore, an existing transaction cannot be modified.
It is safe.
