open market for real-estate crowdsourcing

[synctext]

Market platforms such as AirBnB, eBay, Uber, and Blandlord.com bring supply and demand together.

Based on our ongoing "blockchain-regulated markets" we now explore usage in various domains. This issue addresses an open market for crowdsourcing in real-estate.

Outcome of initial brainstorm sketches:

Sprints:

• Week 1-2: Write-up of context and understanding of problem, understand related initiatives. Describe at least 10 initiatives. Learn Python.
• Week 3-4: Apply Python. Visualize the concept using PyQT designer with 4 operational screens. Feedback round from bank.
• Week 5-6:
• Week 7-8:

Roadmap:

• Feb/Jan: we have 3 components ready in draft: operational market + GUI implemented in QT + business case
• till April: define API between market and business logic, create business logic core, integrate the market, business logic, and GUI.
• April: present MvP results

Various markets for real-estate already exist, such as:

Plus an operational crowdsourcing market, running locally which TUDelft indirectly has access to:

Big promises website, big amounts, high return, risky:

ToDo for next week:

• Each picture of assignment with piece of text
• identified missing screens
• pretty digital pictures of each screenshot
• reading of real-estate stuff
• understanding disruption of crowdsourcing
• problem description first draft

Is it somehow Tribler-related?

[synctext]

@vi not a core Tribler feature indeed, we're making Tribler broader and business friendly with this.
These 4 full-time working students will finish this work end of Jan.
