Traditionally, a hackathon is intensive, software-driven, and requires prototyping and presentations to try to solve both known and unknown problems. TechCrunch’s Hackathon will bring all that and more, starting with diversity. The blockchain-focused hackathon, with blockchain’s versatile applications and penetration into a seemingly endless number of industries, will bring people with different knowledge base and backgrounds, from game developers to supply chain software developers, from medical software developers to voting application developers.

This year, the Hong Kong Hackathon will precede the main TechCrunch 2018 Shenzhen Hackathon.

Each team has 24 hours to design and develop a proof of concept, and judging and awards come from the most innovative companies in the world.

The Hong Kong Hackathon is comprised of two challenges by our partners Wanxiang Blockchain Labs and QIQ.

The Challenges

Task 1: How to design a blockchain-based decentralized identity system for financial services? by Wanxiang Blockchain Labs

Identity systems, like usernames and user data, are a key element of most commercial services. Examples of identity systems include social media accounts, credit scoring accounts, public services accounts, and digital wallet accounts. Currently, almost all online identity systems are managed by centralized parties. Your accounts and data are controlled by third parties and stored on their servers. The disadvantage of this approach is its lack of protection to users on the unauthorized use of their data, its lack of data portability for users to transfer data to other platforms, and its susceptibility to malicious hacking. Your task will be to create decentralized identity systems that improve user experience in financial services.
