Considering the modern internet’s many vulnerabilities, it’s safe to say that traditional email systems don’t score highly on security. Traditional email is fast becoming obsolete, with its authentication carried out via username and password only, while the information itself is stored in plain text on the server. Nevertheless, email remains one of the most widely-used communication platforms. In 2018 alone, the number of global email users amounted to 3.8 billion — a figure set to grow to 4.4 billion in 2023, further highlighting the need for an improved system.
In a traditional email system, the transfer of messages from sender to recipient passes through multiple computers between the two points. In addition to the user, many other parties, including mailbox holders, email service providers, and even the network provider may have access to the mail. They could, in theory, modify the content of emails without notifying the user.
In the current email transmission process, the content data is encapsulated in clear text and exposed to universal ports, leaving the data open to easy interception. Network monitoring equipment or software could seize email data information.
In addition to issues around access security, email systems’ data is stored centrally, so vulnerabilities in a storage service may compromise private content. Failure of email services, either through software or hardware failures, may also lead to loss of meaningful communication. After accessing the computer through these vulnerabilities, an intruder can readily obtain the email address and corresponding username, password, and email content. If there is an email address book, the contact information of those users is also exposed.
Creating a secure email system requires more than just data encryption. Such a system would encompass security between the sender and receiver, and the encryption of data between email servers. It would also contain mechanisms to prevent email domain spoofing, verify that messages have been sent from valid domains, and encrypt transactions between email servers that forward email for delivery.
The solution to reducing and removing these vulnerabilities lies in the combination of blockchain technology and email technology so that the blockchain authenticates both the sender and the recipient of the blockchain email.
ZeU Crypto Networks has launched MulaMail, a fully protected, end-to-end encrypted email and messaging system built on blockchain technology.
Benefits of MulaMail
· Built on blockchain: Mula provides privacy and security.
· Reclaimed privacy: Messages remain fully private and cannot be scanned or read by anyone one than the user, not even the company, big tech or government organisations.
· End-to-end encryption: MulaMail is encrypted, so users control their encryption keys, making data secure both for user and recipient.
· Immutable: Mula is blockchain-based, it records emails forever so they can never be lost.
· Spam-free: Mula uses a whitelisting approach whereby the sender needs permission to communicate with the user, so users never receive any unwanted emails.
· Rewards: Mula will offer exclusive rewards for early adopters and influencers.
Advantages of blockchain-built email
These systems offer unparalleled levels of security while ensuring that your messages will never be lost, deleted or altered. Because the blockchain email system’s database cannot be corrupted, there would be no loss of information or messages. Messages sent and received via blockchain-built systems cannot be modified.
Furthermore, there is no central email server, which means increased security and less vulnerability to hacking and theft. The blockchain network is verified and authenticated by each member, which means that malicious actors would not be able to impersonate other users. It would be more difficult to send spam messages since these messages would need to be verified.
The need for privacy
Users’ internet records are retained, which means users are under constant surveillance. The internet service provider companies, telecom operators, and communication service providers may store your data for an extended period of time and make it accessible to authorities. Any internet activity connected with a specific IP address leaves an electronic footprint that everybody, from the ISP to Google, can use to monitor a user. Most online services keep records of your details under the guise of improving user experience, which, in effect, puts users under surveillance. The promise of blockchain-based email is unprecedented privacy.
Challenges of blockchain-built email
Some limitations still need to be overcome for blockchain-built email to become widely adopted. One of the main challenges is the compatibility between blockchain and standard email systems. To ensure a message and its content does not leave the blockchain and is therefore kept safe and private, blockchain email services have to develop unique solutions.
Furthermore, blockchains are generally not built to transfer or store large attachments, a feature that could limit the use potential of blockchain email systems. Bitcoin, for example, uses a blockchain that was 210GB as of April 2019. While that may seem like a large database, it cannot accommodate typical mailbox sizes. The average email is 75KB and considering there are 102.6 trillion emails sent every year, it means that a blockchain email platform with even a small number of users would quickly run into storage problems.
Overall, successful blockchain email systems will require more than just technical accomplishment. They will need to prove that they are more practical than traditional email and social media, meaning that they must provide high user-value to get traction in the market.
