That is, it informs the amount of digital coins transferred, who made the transaction, the destination account, when it was carried out and even the location of the blockchain in which the operation is registered.
In blockchain, all information is stored in blocks. Each of them has a summary of the data, called a hash.
In this way, a block is formed by the information contained in it, its hash and the hash of the previous block. You hash must be compatible to form the chain, therefore, they are dependent on each other.
Those responsible for verifying all transactions and recording them on the blockchain are called miners.
All information must be considered legitimate before being entered into the system by miners, by consensus of the simple majority of the network.

Blockchain technology is highly secure. This happens because the network only exists in the cloud, that is, over the Internet, without being centralized in one location or device.
In addition, the system has several layers of security, leaving it protected from intrusions or any type of attack. If there is any attempt, the blockchain automatically locks, preventing data breach.
