    {

        Index = index;

        Timestamp = timestamp;

        Data = data;

        PreviousHash = previousHash;

        Hash = CalculateHash();

    }

 

    public string CalculateHash()

    {

        // Implement hashing algorithm here

    }

}

 

This code snippet provides a basic outline of what each block in your blockchain will consist of.

    public Wallet(string address)

    {

        Address = address;

        Balance = 0;

    }

 

    public void Transfer(Wallet recipient, decimal amount)

    {

        if (Balance >= amount)

        {

            Balance -= amount;

            recipient.Balance += amount;

        }

    }

}

 

This basic wallet structure allows for the transfer of funds between users, a crucial component of any blockchain application.
