Abstract
Keyword: Blockchain, Big data, Decentralized
Today, we are living our digital lives creating massive amount of data fromeverything we do. Big data is the new oil, yet the ones who contribute the most of it
are unaware of that treasure. Most service providers collect users’ data with nointention to disclose the reason and the intrinsic economic value, meanwhile, users
trade their data unconsciously in exchange for a free app or service.
What if users could control their data and be rewarded accurately for the value itcreates?
The solution is a decentralized, transparent data exchange economy, based onblockchain technology.
We will now introduce Measurable Data Token (MDT), a crypto token for adecentralized data exchange ecosystem. MDT connects data providers, users, anddata buyers, and denominates the data’s value when exchanged. MDT enables amore efficient, transparent and honest market for data trading.
The first component of this ecosystem is MailTime Email Messenger , a messenger
solution based on the email protocol. MailTime Email Messenger connects users
with a smooth communication experience. It will be the first service to adopt the MDT
ecosystem and utilize it as a payment system to reward all parties involved.
Our vision is a Decentralized Data Value Exchange Economy for everyone in thedigital world.

It’s no longer a secret that technology companies are collecting and mining user
data. Users download an app which seems to be a free, but unknowingly they
compromise their data as a trade-off. It’s an unspoken rule in the industry that,“Every company is a data company”. Companies strive to mine more data fromservices and users to profit from the inherent value of information.
Some of them try to hide this intention by posting ambiguous Terms of Services on
their websites that most users will give up reading. Even more egregiously, some
services that generate revenue from users’ data aren’t even offered for free.
2.1 An Inefficient Market
Services and products store and collect user data for different reasons. The main
purposes for collecting user data include: Advertising, Product Enhancement, andBusiness Insights.
Take Google as an example. When you first sign up for a Google account, Google
attempts to collect your name, email address, password, date of birth, gender,
telephone and address (Google Privacy 2017). These information help Google know
more about their users, thus enabling the company to push more relevant content oradvertising to users. When you use a Google account, it collects the emails you send
and receive from Gmail, the contacts and calendar events you add, the photos andvideos you upload, the Docs, Sheets, and Slides you author, all in pursuit ofenhancing the product experience and generating profits. As a huge entity with awide variety of services, Google does not typically share its information to a third
party simply to marginally increase profits, since users’ data for its own sake is very
helpful for the company.
Location based service Foursquare is another example of tech companies collecting
data. They store and analyze users’ data for Business Insights. Since the mainfeature of this service is to allow users to share their location as a social media post,
Foursquare frequently stores user's’ location data. In early 2016, the company
released an in-house big data product called Foursquare Location Intelligence on thebasis of all the user location data they have collected. Soon thereafter, they released
a report predicting that, according to the data they have, sales of the famous
American food chain Chipotle (a publicly-listed company) would drop 30% in Q1.
Even though Foursquare collects location data which seems to be quite personal, it’s
not actually Personally Identifiable Information (PII). They know fewer users stepped
into a restaurant one month compared to the previous month, but they do not knowthe identity of those people, because this information is irrelevant in a big data
product. Although it’s inevitable that companies will eventually mine sensitive datafor profits, the current reality is that most tech companies and products do not tradeusers’ PII data.
While internet users knowingly allow their data to be collected, they are typicallyunaware of the uses for that data, which leads to insecurity and suspicion. Thissuspicion about the services they use online has led some to block Cookies tracking
and ads online to protect themselves.
From 2015 to 2016, the number of users using ad-blockers on either desktop or
mobile surged to a new high (PageFair 2017 Adblocking Report). Even prestigious
companies like Google are facing concerns about exploiting user data. In June 2017,
Google decided to discontinue the practice of scanning users’ emails for advertising
purposes.
Is anonymous data collecting really detrimental to users? If the market is one-sided
and users’ data is unfairly exploited by data collectors, then the answer is decidedly“Yes”. When users can participate in the process and receive incentives for sharing
their data, then the process becomes fairer and even beneficial for users.

2.2 Traditional Data Trading
A traditional data trading model mostly consists of three parties: Data Provider, Data
Buyer, and Users. In the current model, only the economic incentives of Providers

and Buyers are aligned, but in the new model we propose, incentives of all three willbe aligned.

Data Provider
Data provider is the medium where data is generated. It can be an app, a website, or
any service that acquires and retains users. Use cases for the collected data include:-

Tracking users behaviour for product enhancement
Precise advertising where revenue is shared with advertisers
Selling anonymous user data to third party buyers

Data Buyer
The buying entity can be a merchant, advertiser, investor, big data institute, or othercompany that requires the data to predict trends or make decisions. As an example,
a consulting company without direct access to first-hand user data could purchasedata from a third party provider. Since it is difficult to verify the actual source of thedata, mostly buyers do not have guarantees from any party that the data they got isreal, clean or even legal.
User
End users who willingly or unwillingly share their data with all other parties. In thecurrent model, their data sharing activities have no economic gain.

3 A Decentralized Data Exchange Economy
3.1 A new ecosystem for data exchange
The era of trading data without user consent is over. The new ecosystem isdecentralized, impartial, and mutually beneficial. To change this unfair and inefficient
trading model, we need a new platform and unit of data exchange.
The first step towards fulfilling this vision is to introduce Measurable Data Token(MDT), a new token for data exchange.
Measurable Data Token (MDT) connects users, data providers, and data buyers anddenominates the value of data. It compensates users for sharing anonymous data
points while providing data buyers and providers with a more efficient trading model.
The MDT is a blockchain-based distributed computing platform with smart contracts
securely stored in the Ethereum blockchain. It denominates the value of data in thisnew economy.

In this new ecosystem, sharing one’s data is no longer a superfluous behavior; users
are incentivized with MDT for the actual data points exchanged. By offering moretransparent knowledge of each data exchange for all parties, users will also be more
motivated to join this initiative.
On the other hand, buyers are also provided with a more efficient exchange model
where all transactions are strictly enforced with cryptographically secure smart
contracts. In traditional closed data exchanges, buyers used to be at risk of buying
invalid or fake data without any ways to verify. In this new open model, buyers alsoparticipate in the validation process of each transaction which ensures they will
receive a more trustworthy and risk-free deal.
3.2 Token Technology
Measurable Data Token (MDT) is a token based on Ethereum, and is the mostimportant element in this new data exchange ecosystem. Smart contracts, which areapplications stored in the Ethereum blockchain, are constructed by data providers,data buyers and the MDT platform. Using cryptographically secure token contracts
helps enforce performance of the contracts. To precisely elaborate the technology of
the MDT ecosystem, the definitions for all the entities are listed below:
Measurable Data SDK
An open-source and free SDK(Software Development Kit): offered by MDT ecosystem forany data providers or developers to use. The SDK includes a wallet address of which users
can take advantage to manage their reward income from the MDT ecosystem.

Data Provider​:The entity that is capable of collecting user data, and utilizing the MDT ecosystem toperform data exchange and user rewarding.
User​:
End users who opt into MDT ecosystem and share their anonymous unidentifiabledata will receive reward income from the MDT ecosystem .
Data Buyer​:
The entity that purchases the right of use of the data points during the exchange. It
could mean accessing a database, or purchasing a big data report offered by a data
provider. Buying data in the MDT ecosystem currently does not entail purchasingdata ownership.
Measurable Data Point​:
Each data point invoked in the transaction, with verified economic value in the MDT
ecosystem.
Measurable Platform​:
A decentralized data exchange platform where all transactions are based on smart
contract technology. Initially the Measurable Platform will be administered by the
MDT foundation and will charge calculation fees from each transaction, however,
over time, it will be purely based on the smart contract technology.

MailTime Email Messenger is an email messenger app that helps users manage
their email as simply as messaging on mobile. As a data provider, it collects andanalyzes users’ anonymous email receipt data, and transforms it into valuablebusiness insights, which updates daily right after the purchases happen.
Gaming company J is a data buyer, who constantly look for competitors’ sales trends
for decision making. They discover that MailTime Email Messenger has published a
new data dashboard product called “Sales Trends for Game P and Game C in 2016”that they are interested in purchasing.
After Company J clicks the Purchase button on MailTime Email Messenger ’s
website, this request notifies both the MailTime Email Messenger and the
Measurable Platform.
Thereafter, Measurable Platform constructs a Smart Contract which includes:-

Public User Key, which means all the invoked data points and the respective
public user key
User reward percentage: ​u %Data Dimensions: iTunes email receipts, quantity...
Transaction Price：​Va​ MDT
Transaction Condition: Accepts deal within ​y ​hours

Data Buyer sends ​Va​MDT to the contract address and then gets the preview accessto the product requested. According to the conditions in the smart contract,
Company J needs to decide if they accept the deal within ​y​hours. Within ​y​hours, J
believes that the data is valid and the deal is accepted. After the acceptance, theSmart Contract executes, and simultaneously J gets the full access to the product.
-

Measurable Platform gets calculation fee: ​Vm = Va * x%User reward total is ​Vu = (Va-Vm) * u%, ​each user’s reward varies dependingon their contributing points amount
MailTime Email Messenger as a Data Provider gets the remainder ​Vo = Va Vm - Vu

If J does not accept the deal in this case, and believes that the data is invalid or
problematic, the transaction will automatically go through arbitration on the
Measurable Platform. If the arbitration result is deal accepted, the Smart Contractexecutes. If the result is deal failed, Company J still needs to pay ​x% ​calculation fee
to the Measurable Platform, and the balance returns to the J Company.
It is very likely that for any early adopter, the number of data points being invoked is
not large enough to get considerable rewards.For some users, it may take longer
time to reach the amount other users only take several days to achieve. After all, thedata points every user creates are different.
To solve the potential issue of micropayment and delay in transaction confirmation
times (for example, when the rewarded MDT is too small that it fails to cover the costof Ethereum transaction), MDT will first introduces a reward deposit pool where it
stores users’ micro-rewards until the quantity reaches an appropriate threshold to besent to the user.
Users will be notified in their wallet about the number of contributed data points andthe amount of reward earned. Only once the rewarded MDT reaches a validated
amount will the wallet be activated to use. Users can transparently check reward
income and data points in real time to monitor their status in the MDT ecosystem.
For example, User F downloads the MailTime Email Messenger app and opts in tojoin the MDT data exchange ecosystem. In the first week, his email receipt data is
invoked so his wallet displays the current rewarded MDT amount and the data points
he has shared so far. The number is below the threshold to activate his wallet, butthree months later, the number reaches the verified amount and User F is able towithdraw, make purchases, and transfer his MDT.
We have witnessed many progress in the areas of efficient payments, scalability andmore improvements from projects like the Casper Research, the Raiden Network,
Tendermint / Cosmos , Graphene, and Decentralized cloud computing Dfinity(Ethereum Blog 2017). To enable a more scalable, cost effective system, MDT looks
forward to working with the blockchain community on testing and improving these
new technologies in production.

4.1 MDT Integration in MailTime Email Messenger
Messenger apps have become the preferred means for communicating for simplicity,
but the market is fragmented. All the messengers, such as WhatsApp, Facebook
Messenger, Skype have proprietary, closed platforms. To use them, you have to beon the same platforms as all of your friends.
According to the latest report from Tencent Penguin Intelligence, Wechat now has
889m active users as of 2016. The number of daily active users who spend over 4
hours per day has doubled since last year. In April 2016, Facebook Messenger also
boasted 120m monthly active users.
On these huge platforms, users manage their social lives, bank accounts,transportation, entertainment and many other services. To make their users stay andinvest more time and money, platforms like Wechat and Facebook spare no efforts
to develop as many features as they can. Meanwhile, these huge platforms areclosed networks where users can only interact and communicate with others in the
network, and use services and features exclusively on the same platforms. Users are
increasingly living their digital lives in different closed bubbles controlled by different
giant tech companies.
Email is one open and universally used communication protocol. MailTime Email
Messenger is a messenger app built on top of the open protocol of email, whichmakes it a natural fit for adopting a decentralized solution.
Being an open communication platform is not enough, in the future, MailTime Email
Messenger is going to be a blockchain-based, open messaging platform to support
the new currency MDT, and help establish the new MDT economy.
As the second important element of the MDT ecosystem, MailTime Email Messenger
is launching soon on the iOS and Android app markets first.
The MailTime Email Messenger team are veterans of messaging apps. They havesuccessfully developed two popular messenger apps, MailTime and Talkbox Voice
Messenger app.
MailTime is built on top of an open protocol to enable it to become as pervasive as
email or text messaging, with maximum market potential. Debuted at the
TechCrunch startup battlefield SF, backed by Zhen Fund, Gary Rieschel (Qiming,
Softbank), Crystal Stream (VP of Engineering of Baidu), Y Combinator, Mark Pincus

(Founder of Zynga) and Magic Stone, MailTime was awarded one of the App Store’s
Best of 2015 and has reached over 3 million downloads. MailTime app was also
awarded the Best Lifestyle app at the “Best Mobile App Awards 2016”, and thewinner of “4YFN” innovation award at the WMC 2017.
Another former project of the team, Talkbox, was the first voice messenger app, with
13 million users. This functionality of “Push a button to Talk” was eventually adopted
by major tech companies and is now a feature in most messaging services.
However, because Talkbox was a closed network, it ended up at war with otherclosed networks, fracturing the voice messenger world into several incompatible
ecosystems.
From Talkbox, MailTime to MailTime Email Messenger , the vision of building an
open platform for anyone to use has never changed. As the very first application to
integrate with the MDT currency, MailTime Email Messenger will sit at the center ofthis new digital economy, driving demand and fundamental value for the MDT
ecosystem.
The early version of MailTime Email Messenger supports following features:-Managing unlimited email accounts within one app
Email experience as easy as text-messaging
Earn MDT token from the data exchange economy
Earn and spend MDT from using the MailTime Email Messenger
Store and manage crypto-assets with the built in MDT wallet4.2 MDT User Growth Pool
To drive the MDT ecosystem growth, an MDT User Growth Pool is reserved to
reward early adopters and users with MDT.
In the early stage, users will also get rewards from being active on the platform. For
instance, a user being active for 30 consecutive days will be awarded with certain
amount of MDT.
The currency earned from this User Growth Pool can only be used within the MDT
ecosystem for value added services.
MailTime Email Messenger will keep developing crypto-currency related features toencourage users to join this new economy. As listed in Chapter 4.3 to 4.6, features
like enabling users to utilize their signature as an advertising banner are good ways
to earn MDT currency. Users can also send “VIP Mail” to spend their earned MDT.
More feature like these are in the pipeline, with the aim of engaging users in the new
ecosystem with the least expense. The goal is also to allow users to earn MDT
currency by providing value to the ecosystem and the community through dataexchange, commerce and service creation.

4.3 Advertising with Your Email Signature
Email signature represents a special piece of your online identity. It’s attached toevery email you send, which gets viewed every time someone opens your email.
MailTime Email Messenger allows users to utilize their signature as an advertising
placement.
Would you rather read an advertisement popping up from the website, or something
attached to your friend’s email signature? In most cases, your friend seems moretrustworthy than a strange website.
Users are allowed to decide whether they want to opt-in to the Signature AdvertisingCampaign or not. If they choose to opt-in, they need to select the specific categories
of ads that they are willing to include in their signatures. For instance, they canchoose to include only “fashion” related ads or exclude all “e-commerce” ads.
Advertisers will pay for per activation for all the participating users. MailTime Email
Messenger Platform will also charge a %fee to maintain this feature.
Users of MailTime Email Messenger , however, will not see the email signature since
MailTime Email Messenger hides the user's signature to make the communication
experience as easy as text-messaging. Only those who are not using the app will
see the ads.

Example use-cases:● User B is a freelance writer who needs to email different editors and clients ona daily basis. He joins the Signature Advertising Campaign and opts-in to the“Books” and “Movies” categories for advertisement. Soon under his personal
signature, each email he sends comes with an advertisement banner. Since
the category he selects is quite related to his expertise, the conversion rate of
his advertisement is quite high, thus earning B a considerable amount ofrevenue every month.

4.4 MDT Wallet
For any cryptocurrency economy, a walletplays a crucial part. The MDT wallet will firstbe built in the MailTime Email Messenger
app. In the future, it will be an independent
open source project that can be used byother developers.

MDT is implemented on the Ethereum
blockchain as an ERC20 token, which is acommon standard for issuing digital assets.
MDT ecosystem is designed to benefit all
digital users who embrace an open,
decentralized and beneficial platform. To
reduce the barriers of cryptocurrency
technology for most consumers, MDT walletaims to keep it as simple as possible.
We are also open to a more user-friendly
onboarding tutorial for any crypto-currency
beginners. In the future, the MDT wallet will enable users to send, receive or transfer
payment without understanding the raw technology behind. (Cointelegraph 2017)
Example use-cases:● User C is not a user of MailTime Email Messenger , but he uses anotherService W which also adopts the MDT data exchange ecosystem. C getsrewards from the ecosystem and uses a MDT wallet to manage his MDT
reward income.

4.5 VIP Mail
The VIP mail is an innovative function ofOpen Massager that facilitates efficient
communication between mainstream
consumers and celebrities. It allows users
to connect with influential celebrities orprofessionals who were usually difficult toreach while protecting receivers fromspams by charging the sender.
Even though email is an open protocolthat connects anyone who has an email
address, users need to know the email
address first.
In the past few years, it has been noticed
that there is a growing need formainstream consumers to communicate
with celebrities or professionals directly
and personally. Several products hasdeveloped such features.
For example, Zaihang is a platform which enables celebrity users to post paid
content, for example, a “60-second record answering a specific question”.
(Fenda 2017)
Another SilToken Distribution Event n Valley based startup 21.co offers a service
where strangers can pay bitcoin to send emails to celebrities that are also using
21.co.
One obvious downside of those products is that the closed platform requires bothsides to be on the same platform. Though emailing is a perfect solution for this issue,
it has its own disadvantage since celebrities or professionals would be flooded byspams if they share their email address in public.
MailTime Email Messenger is introducing a new VIP mail service which is foranyone who does not want to disclose his or her own email address. Through the
MailTime Email Messenger platform, user gets a masked email address which is
directed to his or her own email address. Users can set a price for his VIP email
address, for example, “5 MDT”, and then edits his own VIP profile. The VIP user canbe a celebrity, a professional, or anyone who wants to keep his inbox fromspamming.

After creating this profile, users can share this masked email address publicly, on
their business card, personal website, or social network page as a contact email.
Every VIP profile is also searchable on the MailTime Email Messenger Platform,
where a VIP email bot will help introduce users to each other. For instance, if a user
is looking to speak with a professional lawyer, he can ask the bot forrecommendations, and the bot will reply with the best choices on the platform.
When a sender sends an email to a VIP email address, he will get an automatic reply
from the platform detailing how much it will cost to send this VIP email. After thepayment, this email will be sent and the sender will also be notified when it’s openedby the VIP.

Example use-cases：● Professor A does national lecture tours every year, and he always leaves his
VIP mail address at the end of the presentations for the audience to contact
him. He is very busy doing research and teaching so he wants to make surethat those who contact him are serious about their correspondence.
● B is planning on a divorce with her husband, and she finds a suitable attorney
through MailTime Email Messenger ’s chat bot. From the profile, she finds outthat Lawyer C is a famous divorce attorney in the city where she lives and his
response rate is as high as 85%. B sends the payment, successfully sends
her request to C and gets a quick response.

5 Updated Ecosystem Progress
Currently, as of March, 2020, the MDT ecosystem has launched two products:“Data Prodiver (launched in 2019)” - Measurable AI, a business-oriented data analysis
platform that turns anonymous data into sophisticated insights“MDT Wallet (launched in 2019)”- MyMDT Data Wallet Dapp, a user-oriented data wallet forindividual users to get rewards for sharing anonymous data.
Both applications have launched and need the MDT token to facilitate the data exchange inthe ecosystem.

6 MDT Foundation
Measurable Data Token follows Litecoin and other established crypto currencies to
set up a non-profit organization (Public Company Limited by Guarantee) in
Singapore to issue, develop and promote MDT. MDT’s Singapore foundation isapproved and registered by Singapore Accounting and Corporate Regulatory
Authority (ACRA).

ENTITY: MEASURABLE FOUNDATION LTD.
TYPE: PUBLIC COMPANY LIMITED BY GUARANTEEUEN: 201728042H
ADDRESS: 22 NORTH CANAL ROAD #02-00 SINGAPORE 048834
REGISTRATION DATE: OCT 2, 2017
The MDT Foundation aims to be an independent, and democratic governance bodyfor an open and decentralized ecosystem. The principle function of the MDTFoundation is to support the ecosystem partners and provide the technology
necessary to ensure the platform develop sustainably. In order to fulfill the mission,
the foundation is responsible for:-

Overseeing and supporting the decisions related to the ecosystem partners
Supporting research on new ways to improve the technology and governancein the ecosystem
Funding and helping to develop more open source codebase for a sustainableecosystem

It is inevitable that the foundation will eventually be replaced by other moreadvanced and innovative governance methodology in the future. However, we mustfirst create a formal governance model.
The Measurable Foundation will dedicate its resources in Research, Development
and Governance. The funds raised will first be directed to support the developmentof tools that help the ecosystem to build, grow and create sustainable value.

7 Ethereum and MDT
Ethereum is an open-source, public, blockchain-based distributed computing
platform featuring smart contract functionality, which facilitates online contractual
agreements. It provides a decentralized Turing-complete virtual machine, thatenables end users to construct smart contracts for transactions. (Wikipedia 2017)
New York Times commented in 2016 that, “ The promise of such a system is that itallows the exchange of money and assets more quickly and more cheaply thanrelying on a long chain of middlemen.”
We believe that Ethereum is growing to be a ubiquitous technology that not only
serves the blockchain field, but also permeates all areas of life.
MDT will be implemented on the public Ethereum blockchain, an industry standard
for issuing digital assets and smart contracts .
Meanwhile, we are always ready for new technology to surface and will readily
consider any superior solutions.

8 Issuance and Allocation
To finance the MDT roadmap, we will conduct a token distribution that will offer forsale 500 million units out of 1 billion unit total supply of MDT.
---

Maximum financing ：84,000 ETH
Minimum financing：25,000 ETH
Exchange rate in Pre-sale: 1 ETH = 7,500 MDT, which is fixed during Pre-saleExchange rate for Early Bird: 1 ETH = 6,250 MDT, which is fixed during Early
Bird
Exchange rate in Token Distribution Event : 1 ETH = 5,000 MDT , which isfixed during Token Distribution Event
If the ETH/USD exchange rate fluctuates that the ETH price during Pre-sale isgreater than that during Token Distribution Event by ⅓, stakeholders from
Pre-sale will be compensated with the units to match the price difference.
If less than the targeted ETH are raised during Pre-sale, the remaining units
will be reserved for Token Distribution Event

9 Conclusion
MDT team’s vision since 2011 has been to build an open platform. Their first project,
Talkbox, is the first voice messenger app, with 13 million users. This functionality
was eventually adopted by major tech companies and is now a feature in mostmessaging services. However, because Talkbox was a closed network, it ended up
at war with other closed networks, fracturing the voice messenger world into several
incompatible ecosystems. In 2015, They built MailTime on top of an open protocol toenable it to become as pervasive as email or text messaging. MailTime debuted at
the TechCrunch Disrupt startup battlefield, and was awarded “Best of 2015” byApple’s App Store. The team was also invested by Y Combinator, Zhenfund, Mark
Pincus and many prestigious venture capital after its launch.
The journey of being an open platform continued when the vision of MDT surfaced.
As veterans of communication platforms, the MDT team had already identified anumber of established use cases within the new ecosystem and are confident about
its adoption and growth.
