Blockchain technology provides a solution to protect your email security

The global COVID-19 pandemic has undoubtedly clearly defined remote work: the company’s reliability lies in its email service provider’s ability to communicate in various forms.

Let’s start with the source of the email. E-mail has existed for more than 50 years, and it is the official communication channel of the world. It has more than 3 billion users and is the most widely used and instant form of communication.

The first example of email can be found on a computer at MIT, the program is called “MAILBOX”. appointment It dates back to the 1960s.However, it was not until 1971 that Ray Tomlinson invented and developed e-mail. As we know today, it was created by create ARPANET’s network email system.

Email as a communication channel is not really secure

it is estimated People all over the world send about 320 billion emails every day. As early as 2019, enterprise cloud-native security company Avanan Reveal In its “Global Phishing Report”, one out of every 99 emails is a phishing attack, which means that about 300 million phishing attacks are attempted every day in 2019.

As early as 2016, IT security company Hold Security estimated More than 272 million email records and email account passwords were quoted on Darknet.Buzzing example Beginning this year, the well-known journalist Nidhi Razdan filed a cybercrime team complaint with the Delhi police in India in January. She previously said that she had been a victim of a phishing scam that had defrauded the position of an associate professor at Harvard University.Another recently example Attackers use four dangerous vulnerabilities in Microsoft Exchange to gain a foothold in the corporate network.

In addition to security issues, distractions such as email service providers occur every day, such as email service providers reading, processing advertisements, and targeting advertisements to their users. Have you noticed the irony? The moment you create a new email address with Gmail, even before you receive your first email, you are already waiting for a harmful advertisement in your mailbox.

In fact, until 2017, Google used Its technical function can scan all e-mails sent to or from Gmail users to help build the detailed profile of its users so that it can target them through highly personalized advertisements.

Even if we put all security and phishing issues aside for now, it is hard to imagine the idea of ​​an inbox without clutter, spam and ads. Keeping in mind the centrality of e-mail and the various problems that follow, the e-mail service built on the blockchain platform provides a solution for any or all of the shortcomings of the current centralized e-mail service.

What should be the focus of decentralized email?

For email, security is paramount. The decentralized nature of blockchain technology will provide the highest level of security in email. Peer-to-peer networks are not only almost impossible to invade, but they also provide the highest level of protection when it comes to data, personal information, and passwords.

Next comes 100% privacy, which again can be achieved by implementing encryption algorithms, asymmetric key systems and hash functions. In order to achieve perfection here, one must ensure that the best combination is considered and achieved.

You can easily handle the influx of spam emails at all times of the day, and you can use smart contracts to provide a “clutter-free inbox.” When these possibilities can also be integrated with smart contracts, the inbox experience will improve by several levels.

It is possible to create a one-time email address, share it with strangers, and then delete it completely. You can also choose to create a fixed-time email address with a period ranging from one day to several months. This powerful feature makes it easier to choose a reliable provider without the need to have an almost permanent digital footprint with an email address.

If you do not receive any work email alerts from 9 am to 5 pm, then the balance between work and life has actually become a reality. However, in several industries (including cryptocurrency), this is not possible, so the duration can be further customized and personalized according to business needs.

Automatically determine the priority of emails and the ability to delete unread emails. Through smart contracts, emails built on the blockchain network can be provided only to the person in charge, thereby easily controlling access to any employee’s email. Moreover, the inbox will be protected from unnecessary advertising, data mining, monitoring, tracking or analysis.

How should a blockchain solution make the solution successful?

In order to make the above functions a reality in a decentralized system, the blockchain should be:

• Scalability: Today’s blockchain is not scalable. On the Ethereum blockchain, only 15 transactions can be verified per second. This means that it must not process millions of emails every day. Therefore, the blockchain should essentially have the ability to process millions of transactions with almost instant verification every day.

• Sustainable: Blockchain consumes more energy than any existing system.For example, the Ethereum blockchain Consume 1.02 kWh per transaction. This means that if 1 billion emails are exchanged a day, the Ethereum blockchain will consume 1.02 MWh.The energy consumption of blockchain should be light enough to compete with or comparable to centralized systems

• safe Have absolute right to privacy. Even if blockchains are secure, they are vulnerable to 51% attacks, with malicious nodes occupying 51% or more of the network. Cryptographic algorithms, asymmetric key mechanisms and hash functions provide the highest level of encryption. Security is built internally in the privacy mechanism.

That being said, not all blockchains are capable or configured to provide email services. Scalability, sustainability, and security should be carefully considered when choosing a blockchain protocol. Most (if not all) blockchains meet one or two of the three main requirements, with a few exceptions.

When email is used on top of the blockchain, all these problems will disappear, but remember that only when the three criteria of security, scalability, and sustainability are met at the same time, the grass can truly become green.
