Blockchain: Pros and disadvantages compared to traditional services – Bits Media

Web3 solutions, As its popularity grows, Trying to replace many "traditional services", And blockchain technology is slow, But they penetrate the usual Internet correctly. A striking example of a trend is a blockchain mail.

IN 2022 year on the planet
Sent on average 333 billion emails daily. This high indicator confirms the already understandable importance of instant delivery of messages/files/documents in the modern world. Absolutely not surprising, that the enthusiasts thought about the integration of new technical solutions. Consider in more detail the phenomenon of blockchain-cards and the main offers of such services in the market.

Advantages of decentralized mail

At first glance, the blockchain is excellent for email tasks. Thanks to encryption mechanisms and the characteristics of decentralized storage of information, He provides The highest level of privacy and security of messages. Email on the blockchain is mail, which provides reliable encryption, Favorablely differing from old postal services, Since messages are stored in decentralized form, Where access is exclusively with the sender and recipient.

You can compare with competitive advantages of cryptocurrency Compared to traditional finances, caused by a feature of a decentralized and consistent registry, storing information. As in traditional finances, The usual mail is related to the services of an intermediary, providing the provision of the service and storing all the necessary information. The parties must trust this intermediary. There is no guarantee, that their messages will not be distorted as a result of departure or simply merged by attackers. In the case of traditional finances, a similar problem is solved with the emergence of historically the first cryptocurrency, where the blockchain technology was applied for the first time.

An important feature of messages in the blockchain mail is genuineity and immutability-it is impossible to change or remove them from the blockchain. It means, that the message is not subject to any manipulation of third parties and in theory can serve as reliable evidence, eg, In court.

In addition, Of course, Among the obvious advantages will be solving the problem with spam and the integration of the mail on the blockchain into other Web3 products in the environment of Defi, NFT and various multi -sized.

The disadvantages of decentralized mail

At the same time, in a closer approximation, It is worth noting: Mail on the blockchain has a number of serious problems or at least controversial features.

First of all, This is a scalability problem. Only a limited number of transactions in the blockchain can be approved(be valid) Within the framework of a certain period of time. It means, that the blockchain can simply not cope with the load. Considering, that hundreds of billions of messages are sent in the world daily, The risk of overloading the postal service on the blockchain looks real. Although in cryptocurrencies this problem is partially solved due to different solutions in search of a scale scalability, In particular, the choice of a consensus model, providing increased throughput (but often possessing a number of other controversial moments, For example, supporters of the POW solutions sometimes declare, that POS-Consessed does not have the same level of decentralization).

Secondly, there is a problem of compatibility of Web3 mails with messages, sent as part of the usual SMTP protocol today.

Thirdly, Cloval messaging exchange can hardly be free, Therefore, there is a great probability, that each letter will have to be accompanied by a commission for validation on the network. Consider a few examples.

Mailchain

Mailchain is an email service on the blockchain, which allows users of the network to exchange messages, containing investments, HTML and other elements of traditional e -mail. truth, The messages themselves are stored outside the blockchain (It is used to establish a communication channel), to limit the amount of data in a general and unchanged register. At the same time, developers certify, that their encryption measures are quite sufficient.

Service
offers some quota of free messages, After the exhaustion of which will have to pay the commission for each letter (The developers call an approximate amount in $0,005).

Dmail

Dmail is a Web3 infrastructure, offering a postal client with a certain level of protection. Of the obvious advantages, integration with gmail can be noted, Metamask and many other web3 solutions. At the same time from the documentation
the product is not entirely clear, whether the blockchain is used in the work of the mail customer itself, Or is it about that, that the product is simply compatible with projects, Blockchain using.

LedgerMail

LEDGERMAL - Postal
service, working on a hybrid blockchain platform of the XDC network, which uses the consensus mechanism XDPOS 2.0. The service uses asymmetric encryption to safely transmit messages.

EtherMail

Ethermail also
uses a blockchain protocol in the work of his postal client. This product has its own Native Utility Token EMC.

So is it worth it to start mail on the blockchain

Many crypto projects write about their intention to create mail customers or even blockchain messengers, however, already finished and launched solutions so far are very few. This may be due to the minuses of Web3, about which we wrote above. Is it worth using them? Your right to try. However, still other postal solutions, Not involving blockchain, However, offering the advanced level of through encryption (eg, Protonmail or Tutanota), in the eyes of the consumer look no less reliable, But more familiar.
