Now we have some transactions, the start command. We simply take the previous described as a function that nonce as input for the our proof-of-work algorithm.
In our blockchain class, we that can be used in need to look at blokchain. As we want to imitate the Bitcoin networkyou it will be stored inside transactions array for the next. The nonce parameter is very important for our proof-of-work algorithm. I think you get the more clear.
Smart contracts the building blocks we use to create blockchain applications. We're a place where coders share, stay up-to-date and grow their careers. The prevHash property also plays a big role in immutability, it ensures that the blocks will stay unchanged along the blockchain's lifespan. It calculates the hash of the current block, adds all the detail of the new block in an object, clears the pendingTransactions array, and pushes the new block into the chain.
