  • We are using the OOP method because blockchain programming uses the same pattern.
  • You can see blockchain as a document that holds the details of transactions made by a group of people where everyone has a copy.

The pendingTransactions array will hold all transactions that have not been added to a block. To calculate the hash, we need to add a number known as a nonce to the string being hashed. The nonce usually starts from zero and is incremented every time the hash is generated until a hash beginning with three zeros is found. Blockchains do not use just any hash generated because of security reasons. It specifies what the first few characters must look like for the hash to be accepted.
