| Hackathons inject the excitement of fierce competition and strategic decision-making into the often monotonous practice of writing code. With limited resources, technical support, and time, teams of entrepreneurs and coders attempt to develop and implement working programs to solve real problems. For this reason, hackathons are regarded by tech enthusiasts and developers as hotbeds for creative problem-solving. Without the influence of commercial interests, teams form their own perspectives and engage in collaborative development in response to a series of prompts. Held on July 19 and 20, the hackathon jointly organized by Elastos and DoraHacks successfully concluded. Throughout the hackathon, eight teams worked with six prompts for 36 hours. Below are the six prompts delivered by Elastos at the Hackathon: - Use the Elastos ETH Sidechain to run contracts
- Use ELA DID for user identity
- Use the ELA DID Chain to authorize data
- Use the ELA token to make payments
- Use Elastos Carrier to conduct communication
- Use ELA DID to authenticate and issue documents on behalf of users
After 36 hours of deliberation, all competing teams submitted excellent final projects. In the end, the Star Team was chosen as the winner. Below are the 8 teams that used the Elastos platform to develop their projects and the summary each project's goal. Star Team As marathon runners, we have witnessed the rapid growth of this sport in the past decade. Unfortunately, race tickets have become increasingly scarce. We believe the lack of fairness in ticket sales, the rising cost of qualification systems, and the difficulty of transferring tickets have made it difficult for organizers and sports enthusiasts to purchase and exchange tickets at fair prices. At this hackathon, we hope to solve this problem and create a level playing field with 36 consecutive hours of our top-notch efforts. Please visit our booth and check our work.

The multi-sig wallet is a decentralized tool that enables multiple individuals to manage a basket of digital assets together. We also plan to lock the assets with on-chain smart contracts and manage the contracts by sharing the password hash. In addition, we will introduce a gamification mechanism with two distinct roles - initiator and participant - to prevent malicious behavior during the asset lock-in process.

Currently, the plugin supports management and transfer features for the ELA token and Ethereum Sidechain tokens.

Elephant Wallet facilitates token payment and token transfer functions. The wallet also provides a development interface for integrating Mini Programs. As Elastos Browser will be released soon in Q3, 2019, Dapps are urgently needed to enrich the broader Elastos ecosystem. We plan to establish a credible and decentralized platform for guessing games by helping players to create smart contracts on Elastos sidechains.

The signed data will be saved on the Elastos DID Sidechain so that the data collected by the sensor becomes trusted data of the Internet of Things. This collector can be applied to cold chain logistics monitoring, decentralized weather forecasting, and other data platforms.

Our platform operates under three basic premises: - User resumes are stored in the decentralized blockchain maintained by the community, rather than on the centralized server. Thus, resume data has two characteristics: it is owned by individuals and is tamper-proof.
- On the basis that the data is tamper-proof, the project introduces a specific verification mechanism to determine the authenticity of the resumes.
- Third-party entities gain access to verified resume data after completing token payment.
Our goal is to advance our platform to a stage where it serves as a superior, decentralized alternative to Linkedin. - Using blockchain technology, our service ensures the data privacy and enables users to own their resume data.
- Our service establishes a mutual verification mechanism for resume data which requires consensus for the authentication of each resume.
- Our service encourages regular users, headhunters, and companies to construct a blockchain that includes the digital assets for the global talent pool.

Therefore, the applications do not have to rely on a central system to allocate and store all driving information. In this way, it can reduce the huge server operating costs from the central organization; Networked driverless cars can use IOT equipment to collect data and save it on the chain, which ensure real-time security of the vehicle by using the smart contracts on the side chains.

It is a fair competition game with realistic visual effects. A user is motivated to increase his/her strength because it corresponds with significant financial returns.
