Story about bitcoin, What is Blockchain?
The blockchain is a chain of blocks where each of that block contains information of significant worth with no focal supervision. It is crypto secure and changeless. A blockchain utilizes two imperative information structures: Pointers and Linked Lists.
So, what are Pointers in blockchain technology?
Pointers are factors in programming which stores the address of another variable. Typically ordinary factors in any programming lenguage stores information.
Eg. int a = 10, implies that there is a variable “a” which stores whole number value. For this situation, it is putting away a whole number esteem which is 10. This is a typical variable.
Pointers, be that as it may, rather than putting away values will store locations of different factors. Which is the reason they are called pointers, since they are truly pointing towards the area of different factors.
A connected rundown is a standout amongst the most imperative things in information structures.
It is an arrangement of hinders, each containing information which is connected to the following piece with a pointer. The pointer variable, for this situation, contains the address of the following node in it and thus the association is made. The last node, as should be obvious, has an invalid pointer which implies that the pointer has no value.
One imperative thing to note here, the pointer inside each square contains the address of the following block. That is the way the pointing is accomplished. Presently you may approach what does that mean for the main block in the rundown? Where does the pointer of the primary block remain?
The principal square is known as the genesis block and its pointer lies out in the framework itself.
