The Challenge

How to make potential donors willing to donate even though the infectious patients stay anonymous?

1.png

The Solution

To combat the challenge, we present Trackcoin, an app using Federated Blockchain Technology to raise donors' sense of trust and establish an emotional connection with donors, so they would be willing to donate even though the patients stay anonymous.

Build trust through blockchain technology

Leverage blockchain technology to make sure the process is open and provide detailed record, so the potential donors would believe in the platform.

Establish emotional connection between donors and patients

Provide emotional feedback to let donors feel that their benevolence really makes a difference.

User Research

First Round of user research —— Interview

To understand the problem from the users' perspective, we interviewed 11 potential donors using the online crowdfunding platforms which specialize in collecting money for patients who can not afford their treatment cost. 9 of them used to donate in these platforms, and the other 2 have browsed these platforms.

Freelancers

Participants 

Age: 30—35

White Collar

College students

Have browsed but not donated 

Age: 20—25

Used to donate in online platform 

We asked them several open-ended question in order to gain more insights.

Before: Decision making

• What factors would make you intend to donate?

• What factors would make you do not want to donate?

• What factors would make you want to donate more?

In progress: Donating

• What factors would let you give up donating?

• What factors would make you feel good?

• What factors would make you feel bad?

After: Receive feedback

• What factors would make you donate again?

• What factors would make you feel good?

• What factors would make you feel bad?

Based on their answers, we conducted Affinity mapping.

Interview Insights

1. Credibility is the most important factor before donating.

The biggest pain point in donating platform is that sometimes the donors do not know whether the platform is trustworthy, it is a determinant factor of whether they would donate or not.

Platforms' Reputation

Transparent spending record

Verification 

2. Proper feedbacks after donating would encourage more contributions

All the interviewees mentioned that they want to receive proper feedback after donating: Has the situation of patients improved? Can I received some extra reward like privilege in certain areas or certificates? Would the patients give me a thank-you note?

Treatment progress

Emotional communication

Extra rewards 

3.Disclosure of patients' information would influence the intention of donating.

More than five interviewees say disclosing of patients' information would  increase the authenticity and also raise their sympathy, thus they prefer to donate to the patients who provide comprehensive personal information.

Financial situation

Identity information

Personal story 

Whether they are acquaintances

4. The design of interfaces would affect donors' user experience and even affect their decision.

No Ads 

Looks Formal

Second Round of User Research —— Questionnaire

Final Synthesis

According to the user research, we reached the conclusion that there are 6 most important factors that would affect people's intention of donating. From the perspective of psychological states of the donors, the 6 factors can be classified into 3 categories: credibility of the platform, emotional connection between donors and patients, and achievability by extra rewards.

Utmost Concerns

Concerns

Obtain extra rewards

Concerns

Verify patient's information

Check expense reports

Know patient's situations

Communicate with  healed patients

Know patient's information

Trust

Emotional connection

Achievability

Competitive Analysis

We assessed six existing donation platforms on the six most concerned divisions of donors.

Average

18.png

Donors could leave messages to encourage the patients. 

Patients could seldom be reached person to person. Although some of them express gratitude in the update message, it hardly makes donors feel that emotional bonds are established.

The official agency, usually asking people to donate to a general fund, even would not notify the donors what projects their donation supports for.

The commercial online donation platforms provide some virtual rewards, like the "love medal", which are useless to donors.

Detailed condition updates are provided in nearly all the projects targeting individual patients.

The condition updates of the projects targeting vulnerable groups are less detailed.

The online donation platforms provide very detailed patients' information to earn petential dornors' trust and arouse their sympathy.

The official agencies provide less but basic infromation of patients.
 

Official donation agencies could provide donors the opportunity of tax reductions. 

Projects sponsored by charitable organizations seldom update expenditure reports of personal programs. 

Charitable organizations would verify their projects offline. 

Platforms require patients to submit evidentiary materials.  Then the verified information would be posted online.  

Ideation

Problem Statement

In order to define the problems, we created two personas and drew their user journey according to the average level of the six existing donating platforms.

Persona

Lizhi Wang

• 28 years old
• Financial practitioner
• ¥1,000,000/year
• Shanghai

WANG is very astute and rational.  He pays great attention to charity projects for patients because of the memory of his mother, who died of MDR-TB when he was a child always softens his heart. 

Goals of contributing:
-Help tuberculosis patients in financial
-Research the business models of charitable organizations

Frustrations:
-Desire to help patients suffered from infectious diseases but there are limited resources and approaches

-Always worry that his money would be diverted by the platforms 

Frustrations:
-There are little feedbacks on treatment or the condition of patients.

- Can not make sure all her money has been received by the patient and be properly used in treatments.

- Feels upset because there are no thanks

Shanliang Liu

Goals of contributing:
- Gain happiness from helping people out of suffering.
- Feel the personal value

Current User Journey

Ideation: Apply Federated Blockchain technology

Considering the most desirable features, several fundamental needs should be met: encrypted personal information, crowd supervision, and expenditure records’ track. We naturally come up with the idea to apply Blockchain. And we prefer the Federated out of 4 different types.

Smart Contract triggers the execution of contract terms to clients.

Smart Contract 

Info of the requested operation is hashed and packed in a block by the node.

Application layer

When the first block of a blockchain is created, it is marked with a hash function, as the second block is created and added to the chain, it is also marked with a hash function, which includes the part of the first block's hash function.

Data Process

A person starts an operation request to a node that the node should be a hospital or a disease control center. 

The block broadcasts on a P2P network consisting of all member nodes.

Decentralized Network

Consensus
Algorithms

All member nodes verify the block through consensus algorithms (ex. PBPT).

Smart contract is given code in the database, which is trackable and irreversible.  We can use smart contract to distribute money automatically.

Database

Once a block is verified, a new block would add to the database, one after the other, in a way that resembles a chain, hence the name blockchain.

Service Flow

Service Flow of Potential Donors

• Want to donate
  - Have had an infectious disease 
  - Family or friends die of  infectious disease
  - Read news/Ads

• Sign in and select a fund pool 
  - Select by Province and Disease
  - Select the shortest fund pool

• Donate money to the pool
    - Pay through the third party 

 

• Bound to a patient and receive jurisdiction to track the details
   - Including expenditure records and treatment records

 

• Receive thank-you note from the patient and reply
   - Get a sense of achievement and want  to donate more

Service Flow of Infectious Patients

• Import the profile and  create an account
   - Profiles should be imported through hospitals

• Receive donation in the account   

• Pay treatment expense through exclusive QR code
   - Expense would be updated automatically
     - The QR code can not be used in other ways except curing infectious

• Update treatment progress to keep the account available
    - The count would be locked once stop updating for more than 15 days

• Write thanks note to donors
    - Donors' last name would be attached to the card automatically

Usability Testing 1

We invited eight potential users to do user test.

Feedback

“There is too much miscellaneous information on the Home Page which made me very confused. I don't really expect to view news on a crowdfunding platform.”

Six out of eight users think they don't want to read news on Home Page.

"The information on the track page is too crowded."

Five of eight users indicated that there are too much various kinds of information huddling into the track page.

“It is unnecessary that you add a game in the app, it is not bad to create some incentives, but a game is too much.”

Six out of eight users do not think it is necessary to involve a game setting, collecting thank-you note could bring enough incentives.

First Round Iteration 

Add Donation updates

Turn cases into urgent projects

Turn news into thank-you note updates

Turn cases into urgent projects

Hospital Laboratory Sheet

Eliminate access to check the detailed info of the hospital. 

Dispart the information on the initial "track page" into three pages

Eliminate the game page and add more info on the donation feedback

Donate one more time

Timeline

Add a "detail" button

Thank-you notes collection

Item List

Usability Testing 2

We invited 4 people to conduct the second round of usability testing.

Feedback:

Help Button:
"Maybe the location of the help button could be changed, also the name "help" is weird and quite misleading."
Payment:
"Payment methods and amount input can be combined in one page. If I have to operate twice to finish payment, I would go kind of impatient. "
Pool Information:
"When I click to check specific pool information, besides donation proportion, I also expect to know more details, such as the hospitals relate to the fund pool."
