ELEMENTS OF BLOCKCHAIN SYSTEM AND PRINCIPLES

The blockchain systems consist of four main elements are [5]:

• Mass: Represents a chain building unit, a set of processes or tasks to do or to perform within the series, is an example of blocks transferring funds, recording data, or monitoring a case, and usually absorbing.
• Information: It is the sub-process that takes place within a single block.
• Margin: Is the DNA characteristic of the mass chain, sometimes symbolized by a digital signature. It is a code that is produced through an algorithm with a block program called a Margin mechanism.
• Fingerprint Time: It is the time when any operation was performed within the series.

The blockchain system operates according to three basic principles [5]:

1. The First Principle: Open Log: All infonnation within the Block- chain is available to all individuals within the chain, are each other’s property but retain the inability to know their true identity. This is because the series allows individuals to use nicknames other than their real names.

2. The Second Principle: Distributed Data-based: This principle aims to eliminate the idea of centralization. There is no single destination; server, or device controlling the cluster chain; anyone in the world can download, view, and salve the series. This principle is one of the safety elements of a chain.
3. The Third Principle: Mining: Mining means the use of computer energies to find the right margin characteristic of this work imtil it is successful; millions of prospectors around the world perform a series of complex calculations across their devices to obtain the correct margin that links this transaction to the previous transaction within the chain, this is the main function of the mining process it is to ensure that the new transaction took the same period of time as the previous transactions within the chain to ensure that no manipulation or fraud, once the correct margin is obtained the transaction is completed and allowed to enter the chain and is joined to other processes within the block formed at the end of the blockchain.
