![]() This will use sha256 algorithm to calculate the hash of the block using all the parameters and current time. hashBlock():This will take hash of previous block, merkel root & Nonce as parameters.This transaction will be added into the array 'newTransaction'. It will create a new structure called 'newTransactions' which will have seller, buyer, and property Id. createNewTrans(): This will take property Id, seller Id & buyer Id as parameters.getLastBlock(): This will return the last block in the array "chain".createNewBlock(): It will have parameters of nonce, hash of previous block and hash of current block.It will create a new block with all its data and add it to the array "chain".Blockchain(): This function initializes an empty array called chain which will contain all the blocks in sequential order.It will also initialize an empty array called newTransaction which will contain all the transactions in chronological order.It will create the genesis block.Fraud can be easily eliminated.Īn easy to deploy technology to eliminate friction in day to day regular problems, helping make transactions secure and trustworthy.
