Blockchain is an emerging technology that is increasingly incorporated into enterprises due to its immutable, reliable and decentralised nature. Through the National Blockchain Challenge 2019, we are looking for blockchain enthusiasts who want to design the future of work with us. 

The future of work is defined by two elements. Firstly, there is increasing globalization resulting in the gig-economy, which may result in many freelancers not being paid in an accountable, inclusive and trusted manner. Secondly, automation will inevitably result in the indiscriminate wiping out of many professions, and many workers will be displaced. Against this backdrop, how can we use blockchain technology to design a better future of work?

The National Blockchain Challenge 2019 connects institutional, academic, developer and student communities. We encourage teams to build blockchain applications that can result in fairer, more equitable, empowered and prosperous work of the future.

Besides the hackathon, we have prepared a list of master classes, check out the complete list at our website.

This event is supported by Lifelong Learning Institute and our SG Fund. 

Hackathon kickoff will be at 10am, 14 June. Registration will start at 9am, outside LLI Event Hall 1.  

Code freeze will be at 10am, 16 June. You will have 48 hours to work on your project.

Our problem statements 

Kleros - The blockchain dispute resolution layer 

Problem statement brief: We now live in a fast-paced economy whereby globalisation has created transactions and work without boundaries. A freelancer in Singapore can be employed directly by an American or European company. Globalisation and technology have created a more just and level playing field in which the player has the same opportunities. However, this can be a double-edged sword. Freelancers might not be paid in an accountable, inclusive and trusted manner. Blockchain can be used for dispute resolution that is fast, inexpensive and renders the judgment of the enforceability of a smart contract. Kleros is a decision protocol for a multipurpose court system design to solve disputes. 

Objectives to achieve: How could we as users view the interactions, settlement and activities on the blockchain? Develop a dapp to visualize Kleros smart contract activities.

IOST - An ultra-fast, decentralised blockchain network based on the next-generation consensus algorithm “Proof of Believability” (PoB)

 Problem statement brief: IOST see games as the breakthrough point for blockchain applications to drive its early stage adoption. However, current DApp games are facing several problems, including well-designed token economy models, quality of the game, revenue generation etc. The blockchain market needs more high-quality gaming DApps that could continually gain new users and generate profit. 

Objectives to achieve: 
- Design and develop a gaming DApp based on IOST;
- Design a good token economy model or a business model which can help this DApp generate sustainable revenue;

How will a good DApp look like:
- There are no restrictions on categories of the gaming DApps, any kind is welcomed!
- The DApps should be developed with good UI and UX.
- The DApps should have smart contracts deployed on IOST mainnet.
- The DApps are easy to use with clear and fair rules.
- PR and marketing plans should be made along with DApp development, if your DApps are good, IOST can definitely help your teams on all of these!

Progressing beyond the hackathon 
- Once the DApp is selected to be officially released on IOST mainnet, the DApp will be promoted in blockchain communities worldwide and IOST users will experience the DApps.
- The DApps will be listed on tier1 DApp platforms (DAppRadar, DAppReview etc) to get full global exposure.
- IOST will help the DApps on marketing, PR etc to help them continually gaining new users.
- Get sponsored by IOST on further DApp development.

Cybersecurity + General 

Blockchain as a decentralised public ledger may prevent fraudulent activities and detect data tempering. We have seen data leakage, from social media to hospital, identity leakage. Blockchain in itself, being decentralised, prevent a single point of vulnerability, enhancing the security of the data.

Which sector could benefit from the enhanced cybersecurity from blockchain? Create a Dapp on any network of choice that could benefit more and is more effective when using a decentralised solution. Or work on any cool ideas that you have in hand to show us what you got.
