Why do CED choose to build this solution on the Blockchain platform?

• Today, some big fashion brands like Nike have started using Blockchain to authenticate the authenticity of their products, helping to prevent counterfeits and protect consumer rights. Or in the food industry, companies like Walmart are applying Blockchain to track the origin of food, from farm to table, ensuring food safety and hygiene.
• CED, following the Kambria DAOs model, develops Applications on the Blockchain platform with the goal of building a community-owned technology model. In which the community is empowered to make decisions based on the advantages of Blockchain such as trust, transparency, and automation. On the other hand, the application of Blockchain in intellectual property management will allow open-source solutions to be commercialized by their communities.
• Developing on Blockchain also helps the community participating in the solution (Guides and Explorers) to operate and interact with each other from anywhere in the world more easily.

How long does a Session last?

• The standard duration of a Session varies from 20/30/40/50 minutes.
• To ensure the quality of Session content, CED specifies:
  • Guide must attend at least 80% of the standard Session duration. If the Session lasts less than required standard duration, CED will ask the Explorer to confirm that the Session has been completed.
  • On the other hand, if Guides or Explorers are late by more than 30% of the Session duration, or are absent for over 30% of the Session, CED will automatically terminate the Session to avoid disrupting the user experience.
• Guides and Explorers can extend the Session beyond the standard duration if both parties agree.
  • For example, if the conversation is engaging and enjoyable, and both Guides and Explorers wish to continue, they can propose and agree to extend the Session. However, if one party cannot adjust their schedule or does not wish to extend, they can decline.
  • The extension time cannot exceed 60 minutes beyond the registered Session time (e.g., if the Session is registered from 3:15 PM to 4:00 PM, the Session will automatically end at 5:00 PM if extended).

What kinds of topics can I explore?

CED is a community-driven learning platform where people exchange skills, knowledge, and experience through live one-on-one sessions. CED supports a broad range of learning and knowledge-sharing areas, including:

1. Personal Development
2. Educational & Academic Support
3. Business & Professional Connections
4. Creative Collaboration
5. Social & Cultural Exchange
6. Social Impact & Volunteering
7. Technology & Digital Literacy
8. Hobbies, Crafts & Culinary Arts
9. Mind Sports, Strategy & Cognitive Development
10. Psychology, Mental Health & Spirituality

These categories are intended to help members explore possible areas of knowledge exchange, but CED is not limited to these topics. Guides and Explorers are welcome to create, offer, or explore Subjects beyond these areas based on their knowledge, interests, experience, and learning needs. As the CED community grows, new Subjects and Session topics can continue to emerge based on what members want to learn and share.

→ Visit Subject List – Suggested Topics and Examples page for further details.

Is CED suitable for professional advice?

CED is designed for exchanging knowledge, skills, and lived experience. It is not a substitute for professional medical, psychological, legal, financial, or other regulated professional services.

Guides share their own knowledge and experience—they do not diagnose, prescribe, or provide licensed professional advice through CED.

Can the Guide and Explorer swap roles? 

• Yes - Guide and Explorer can absolutely swap roles.
• CED platform is designed as a two-way system, where any user can be a Service Provider (Guide) in one session and a Service User (Explorer) in another session.
• Every user must have at least one active role, but can turn the other on or off as needed. And Users cannot disable both roles at the same time.
• This is a core feature of CED - fluid capacity exchange - everyone has something to learn and something to share.

Do I need to pay to join?

No. Joining CED and creating your account are free.

To participate in Sessions as an Explorer, you will normally need a CED subscription, which gives you access to a set number of sessions according to your subscription plan.

As part of the current onboarding opportunity, up to 50 newly registered participants who complete the CED Registration Form may receive gift codes for two free trial Sessions per month. Gift codes are subject to availability.

Submitting the CED Registration Form does not automatically guarantee gift codes. Availability will be confirmed by the CED Team.

How do Guides earn compensation?

New Guides begin by completing two volunteer Sessions. After these are successfully completed and your Guide account becomes a Service Partner, you'll be eligible to receive US$6 for each completed Session during the pilot.

Payments are made monthly in cryptocurrency through the Kambria ecosystem.

Who determines the Guides’ expertise level?

• Primary flow: The Guide self-declares their expertise by uploading certificates and selecting a proposed level.
• Final decision: CED Admin will review the uploaded certificates and assign/approve the Guide’s official level based on CED’s publicly published framework.
• • Level 1: Short-term certificate
  • Level 2: Bachelor-level
  • Level 3: Master-level
  • Level 4: Doctorate-level.
• The admin’s approval is required to finalize the level.

Why this approach? 

The CED team believes that it balances transparency (public framework + guide-provided evidence) with quality control (admin review) to reduce misclassification, and enhance the user experience while exchanging knowledge and capabilities. 

What happens if the Guides’ certificates expire or is invalid?

• If a certificate is no longer valid, CED will downgrade or lock the Guide’s higher-level permissions, but the Guide’s profile and data remain.
• The Guide will receive a clear notification explaining the reason for the downgrade (e.g., certificate expired, found invalid).
  • For expired certificate: CED will handle via review (the team does not auto-revoke purely on expiry unless there’s a rule to do so); the system relies on reports and admin review for enforcement.
  • For fraud / invalid certificates, CED will treat them as critical. The team will lock high-level permissions immediately and follow escalation procedures (further investigation, possible sanctions).

Are experience-based experts recognized even without official degrees? 

• Yes, but with caveats.
• CED’s level assignment is primarily certificate-based at launch to ensure transparency and consistency.
• Any Guide is encouraged to add detailed profile fields (About / Experience / Activity) and collect community ratings and reviews; these elements will be visible to Explorers and used for reputation.
• Planned improvement (hybrid approach)
  • The model recommends evolving to a hybrid scoring system that combines:
    • Formal certificates (credibility)
    • Profile experience & portfolio (practical expertise)
    • Community ratings and reviews (social proof)
  • This hybrid model is intended to fairly recognize high-skill practitioners who lack formal academic degrees.
• Current operational implication 
  • Experienced-based experts without degrees can still:
    • Host sessions (at levels admin allows),
    • Build strong profiles and portfolios, 
    • Earn high ratings that surface them to users, while admin may assign a level conservatively in the short term.

Can a Guide offer multiple session durations (e.g., 40 minutes for basic and 50 minutes for advanced), or is each Guide restricted to only one standard duration?

• Yes, a Guide can offer multiple session durations, as long as those durations correspond to expertise levels that are equal to or below their assigned level.
• For example, a Level 3 Guide may create sessions with durations for Level 1, Level 2, and Level 3 (20/30/40/50 minutes depending on the mapping). However, they cannot create a session with the duration assigned to Level 4, since that exceeds their verified expertise level.
• This allows Guides to offer both basic and advanced sessions within the scope of their qualifications.

Do I need to understand blockchain or cryptocurrency?

No. You do not need prior knowledge of blockchain technology or cryptocurrency to participate in CED.

If you join as an Explorer, your experience is similar to using other online learning platforms. When you are ready to purchase a CED subscription, the CED Team will provide guidance on setting up a cryptocurrency wallet and completing the subscription payment process.

If you become a paid CED Service Partner, the CED Team will also provide guidance on setting up a cryptocurrency wallet to receive your Session payments.

Is CED safe?

Creating a trusted learning environment is one of CED's priorities.

To help protect community members:

• Users complete identity verification during onboarding.
• Guides undergo expertise verification before hosting Sessions.
• AI-assisted moderation helps identify inappropriate behavior.
• Sessions may be securely recorded for a limited period to support quality assurance and dispute resolution, in accordance with CED policies.
• Users can report inappropriate behavior directly through the platform.
• The CED Team can provide support when users encounter technical or participation issues.
