Pmail (PML)

“The first message the Internet sent was ‘L' and ‘O'. At 10:30 pm, Oct. 29, 1969,

Kleinrock, in Los Angeles, A message was sent to Bill Duval at Stanford University. This

was a five-letter word: Login. After entering “Lo", the system broke down. The instrument

showed that the transmission system collapsed. Therefore communication was forced

to stop. The world's first communication test through the Internet only transmitted two

letters, which were “Lo", marking the creation of the rudiment of the Internet based on

information transmission.”

I. Vision

The transmission of a string of words opened the door to the Internet, thus beginning

the booming development of the Internet. In the Crypto World, we also hope to take

information transmission as a starting point and promote a leapfrog development of

applications in the blockchain ecosystem. Therefore, we established a decentralized

version of NFT mail application called "Pmail."

Based on features of Web3.0 and Dfinity (Internet computer) technology, with mail

application as the entrance, Pmail lowers the threshold for users and developers to

participate in the Crypto World by enabling smooth transmission of information between

traditional mail and blockchain mail, users hereby can use blockchain as if they use the

Internet. We hope that Pmail serves as a basic portal to the blockchain world and a

gateway to the real world in the future.

II. Product overview

To solve problems of interaction, communication and information sharing between

on-chain and off-chain users, we developed a distributed application called

Pmail.

Pmail is the first mail application based on Web3.0 and Dfinity technology that

integrates NFT and distributed storage functions, and is dedicated to building

a bridge between the traditional world and the parallel world. Compared with

traditional mail, Pmail gives rights of control back to users. Users can manage

and access data with their private keys, and can also determine the future trend

of the product through community Governance. Pmail is committed to providing

users with a permanent service without a centralized server, and meanwhile

ensuringe the ownership and privacy of data.

Pmail is the foundation of communication, information sharing and collaboration

of on-chain and off-chain users in the future. Specifically, it will serveas the basic communication and cooperation tool of the blockchain world, and the

gateway for information exchange between the blockchain world and the real world. As

an information interaction gateway in the new era, it will help users connect the whole

blockchain world and the real world, and help users, developers, institutions and assets

to build reliable interactive connection and build an information storage space that will

never be lost in the blockchain world. In this way, we believe that it can better serve the

blockchain world and the real world, and enables everyone an access to an equal access

to different worlds

2.1 Basic realization

2.1.1 On-chain mail address

Pmail provides unique on-chain mail addresses, through which mails and assets are

received and sent.

2.1.2 On-chain mail distributed storage

Through distributed storage technology and authorized encryption technology, Pmail

ensures the security of mails and information stored in cloud.

2.1.3 On-chain and off-chain Interaction

Pmail links the information exchange between the blockchain world and the real world,

and realizes rapid information exchange between on-chain and off-chain users.

2.1.4 On-chain authorization

Through on-chain authorization, users can carry out security authentication, mail

encryption, asset swap, real-world encrypted information exchange and ownership

confirmation.

2.1 Basic realization

2.2 Underlying architecture

The current stage of Pmail is based on the underlying architecture of Dfinity, using

blockchain authentication mechanism, distributed data storage and other technologies to

provide mail services. The main feature of Pmail is linking the blockchain world and the

real world, More real world users can interact with their counterparts in the blockchain

world easily. Both sides can enjoy blockchain functions in an easier way. We hope that

Pmail becomes a basic portal to the blockchain world and an underlying gateway to the

real world in the future.

2.3 Standard protocol

At present, the most widely used email system adopts MIME standard protocol to deal

with multi-type emails. Mails are mature enough to address information transmission,

and various types of data can be included in an independent email, files, Pictures, audio,

video,scripts, and chart and etc could be included.

However, with the development of the era of Web3.0, traditional emails did not catch up

with the upgrading of the blockchain. Hence, Pmail has done a lot of research to solve

this problem, hoping to bridge the Web3.0 era and traditional Internet in a new way so as

to help more traditional Internet users to access blockchain with lower barrier of entry.

Pmail is improved on the basis of SMTP protocol, and a new application is added on the

basis of MIME type Standard to combine the blockchain and e-mail. A complete block

chain data structure is defined on the basis of RFC8555 protocol to solve the above

issues. Pmail is submitting the standard and solution to the IANA and the U.S. Patent

Office for a new U.S. technology patent.

2.4 Basic function

2.4.1 Unique identity

Unique identity is Pmail's basic authentication feature. The identity information is updated

according to the information authorized by users. Users can create their own unique

mail name to communicate and interact with other users. Privacy will be ensured, and the

spam will be filtered.

2.4.2 Mail function

It provides basic functions as traditional mail such as receiving and sending mails,

sending attachments, sending assets, etc. Users can send such information as assets

(Token and NFT) through alias mode or blockchain ID mode.

In addition to the sending and receiving between on-chain mails, Pmail can also transmit

information and assets between traditional mails and blockchain mails, which is our

original product feature.

2.4.3 Asset function

The Pmail mail can define any mail of a user as an asset, and can also store users'

encrypted assets and NFT assets. With this feature, users can manage their assets,

including storage and transmission

2.4.4 NFT mail

Pmail was the first project to create NFT mails. In Pmail, we expanded form of NFT.

Each mail address is an NFT. As such, mail is not only a communication tool, but also an

invaluable asset. User's mail account can be traded anytime as an NFT asset, and those

mail addresses with special meanings may be worth more in the market.
