- In blockchain, we have multiple blocks together and they are connected using Hash values.
- Every block has 1 or many transactions and each txn have their own hash ID, that then means that a block can have numerous hash values for each txn
- To get the one hash value of one block, we use the Merkle tree formulae.




•For those 10 transactions, they have 10 hash . So to get 1 hash, you will find 1 common hash between two hash i.e. h1, h2 =h12, h3,h4 = h34
•Once that step is done, get one common from the two i.e. h12,h34 = h1234
•Continue with the sequence until you end up with one hash.
