Cryptocurrency Bitcoin story, blockchain explained

On the off chance that you are pondering what the “hash pointer” implies, it is a pointer which contains the hash of the previous block.

As you may have speculated at this point, this is the thing that the structure of the blockchain depends on. A  blockchain is essentially a linked list.

The blockchain is a linked list which contains information and a hash pointer which focuses to its past block, consequently making the chain. What is a hash pointer? A hash pointer is like a pointer, however rather than simply containing the address of the past block it additionally contains the hash of the information inside the past block.

This one little change, is the thing that makes blockchain so incredibly solid and trailblazing.

Envision this for a moment, a programmer hacks block 3 and tries to change the information. Due to the properties of hash works, a slight change in information will change the hash definitely. This implies any slight changes made in block 3, will change the hash which is put away in block 2, now that thus will change the information and the hash of block 2 which will bring about changes in block 1 and so on. This will totally change the chain, which is not possible. This is precisely how blockchain accomplish unchanging nature.
