An Algorithm that Prevents SPAM Attacks using Blockchain

Abstract: There are many systems and methods for prevent-ing spam attacks. However, at present there is no specific tried-and-true method for preventing such attacks. In this paper, we propose an algorithm, “SAGA BC” to prevent spam attacks using a blockchain technique and demonstrate its effectiveness by a simulation experiment. A person who sends an email using the “SAGA BC” must pay the processing cost with cryptocurrency. If an e-mail sent using this algorithm is received normally at a destination e-mail account, this fee is refunded. However, a lot of spam e-mails are not received normally, because addresses of the spam e-mails are indiscriminate. If a spammer sends spam using the “SAGA BC ,” he/she will lose the cryptocurrency fee for each such message. Thus, if using the “SAGA BC” to send e-mail becomes a standard practice for the general public, receiving e-mail servers and/or mailers will be able to easily judge incom-ing messages without using the “SAGA BC,” because spammers cannot use the “SAGA BC” without losing their cryptocurrency.
