Dev Release 88

Hello BlockDAG Community,

As we wrap up another productive week, we want to share a quick recap of our progress and key updates.
Weekly Recap
Application Testing and Production Release
We started our week with comprehensive testing of the BlockDAG X1 application to ensure the latest updates are stable and ready for production. This rigorous testing was crucial to maintaining the quality and reliability of our application.
Addressing User Queries on Phone Number Bans
Several users raised concerns about their phone numbers being banned. Upon investigation, we identified issues with our phone number validation service. We revised our validation logic to allow additional categories of phone numbers, resolving this issue for affected users.
Successful Build Delivery
By mid-week, we successfully delivered the latest build to production. Internal and external stakeholders thoroughly tested this build, and upon receiving their approval, we uploaded it to the Apple, Huawei, and Amazon stores. The latest APK of the application is also available for our users.
Blockchain Explorer Phase 2
For the blockchain explorer, we completed and tested Phase 1, sharing it with stakeholders. We have now embarked on Phase 2, which will include support for UTXO transactions and smart contracts.
 

Let's jump to the latest update for today:
Enhancing User Authentication
We have received numerous complaints about OTP (One-Time Password) delivery issues. To prioritize user experience, we are implementing additional authentication methods, specifically email verification. Our team has been working diligently on this today, integrating SMTP (Simple Mail Transfer Protocol) into our Golang codebase and creating email templates for this purpose.
Pseudo Code for Email Verification Implementation
Here's an outline of the algorithm we are using to implement email verification with accompanying pseudo code (Note: that this is just an example implementation and does not reflect the same method names):
 

1. User Request: User initiates the registration process or requests email verification.
   function handleUserRequest(user): 
   verificationLink = generateVerificationLink(user)
    sendVerificationEmail(user.email, verificationLink)
    
2. Generate Verification Link: The system generates a unique verification link containing a token.
   function generateVerificationLink(user):
      otp  = generateUniqueOTP()
      storeOtpInDatabase(user.id, otp)
      return "https://blockdag-x1.com/verify?otp=" + otp
    
3. Create Email Template: An email template is created, including the verification link and relevant instructions.
   function createEmailTemplate(verificationLink):
      return "Hello,\n\nPlease verify your email by clicking the following link:\n" + verificationLink + “\n\nThank you,\nBlockDAG X1 Team”
    
4. SMTP Setup: Configure the SMTP server with the necessary credentials and settings.
   function setupSMTP():
      smtpServer = "smtp.example.com"
      port = ***
      username = "[email protected]"
      password = "your-email-password"
      return smtpServer, port, username, password
    
5. Send Email: The system sends the verification email to the user’s email address.
   function sendVerificationEmail(to, verificationLink):
      smtpServer, port, username, password = setupSMTP()
      emailBody = createEmailTemplate(verificationLink)
      smtpSend(to, "BlockDAG X1 Email Verification", emailBody, smtpServer, port, username,                                password)
    
6. User Clicks Verification Link: The user receives the email and clicks on the verification link
7. Verify Token: The system verifies the token from the link against the token stored in the 
8. Update User Status: Upon successful verification, the user’s status is updated in the system to 
9. Confirmation Notification: A confirmation message is sent to the user, indicating successful email verification.

function sendConfirmationEmail(userId):
   user = getUserById(userId)
   emailBody = "Hello,\n\nYour email has been successfully verified.\n\nThank you,\nBlockDAG X1                             Team"
   smtpSend(user.email, "BlockDAG X1 Email Verification Successful", emailBody, smtpServer, port,                                           username, password)
 

We are committed to continuously improving our user experience and are excited to roll out these enhancements. Stay tuned for more updates!
Thank you for your continued support!
