This is the structure of block in chain.
To create Hash we use cryptography.
It has data, hash and previous hash.
These are multiple block forming a chain
Here the previous hash of the block is equal to the hash of the previous block.
The hash is made from the data in the block by using the cryptography.
Data tampering Prevention
Data tampering Prevention
Because of the chained network of the computers, if any tampering occurs then the address or hash of the block created by the data changes and the whole chain gets distorted so the data tampering can be prevented.
