We are excited to announce the results of the Imaguru Blockchain Hackathon which ended the weekend of October 5-7, 2018 at Imaguru Startup Hub in Madrid. With the photos and videos we hope you will have an idea of the environment throughout the event and with the links to GitHUB, we want to show the progress we all made together.

The main objectives of the hackathon were to form teams and then offer them help from our experts. The main objectives were:

  • Formalize an idea and create a work plan for the next 48 hours.
  • Make enough progress to present a demo and prototype.
  • Have the idea of how it can be continued with further development in projects after the hackathon.

To do this all in a single weekend, we invited the best mentors from both technology and business. In the case of the blockchain hackathon, there were 5 Imaguru senior level blockchain developers.

The developers offered help to all teams with their prototypes in blockchain (code, smart contracts, project architecture, etc.) and every day they offered technological consultations. In addition, they organized a smart development master class for all participants, taking as an example the smart contract of one of the teams.

As business mentors we had 9 specialists from blockchain, business development and startups from different Spanish companies. They listened to each team during mentoring sessions, gave advice, asked questions and evaluated progress. They then worked with each team in a free format.

The mentors who worked all weekend to make our event possible are:

  • Tania Marinich, Founder of Imaguru
  • Borja Gonzalez del Regueral, Vice Dean at IE School of Human Sciences and Technology
  • Enrique Sánchez Sumozas, Entrepreneur and Innovation Business Development at Digital Emerging Technologies, Minsait
  • Pablo Romero Alfonso, Client Solutions Strategy at BBVA
  • Gustavo Segovia, Senior Partner at Innovation Lead Blockchain Open Lab
  • Cristian Garcia Fernandez, Blockchain and Innovation Specialist at Nakima
  • Ferran Prat Tiò, Blockchain Specialist, Strategy and Development at Nakima
  • Salvador Casquero Algarra, Co-Founder of 2gether.global, the first collaborative bank
  • Adrián Bernabéu Escudero, Co-Founder of Cryptoinvest

Here you can see the interview we did for them.

And now we will share the projects of each of our teams.

Hunted Objective
A website that validates employees’ skills with the help of blockchain (using Truffle framework). The team made a «pivot» during the hackathon. They came up with the idea of developing the application to validate university degrees with smart contracts but after the mentoring session they changed their minds to find the best way to build and monetize it.

The operation consists of three stages. First the user (the employee) enters their data into the system, then the companies validates each skill of this employee and in the end that information is shared with the company that needs it.

Team Members: Boris Villazón, Daniel García, Alberto Santiago, Tomás Castaño and Miguel Castanedo.

An application in blockchain so that all those who travel by bike can know if different places, shopping centers, restaurants and etc. are bike-friendly. The idea is to connect the community of cyclists with the community of shops that can offer safe places to leave a bike as well as offer discounts and promotions for cyclists.

Each user has access to the map of Madrid with all the places where you can leave your bike. At the same time, the application is like a network for cyclists because users can leave references and evaluate sites through the social network at Blockchain Golos.io.

Team Members: David Saiz Camarero, Patricia Polo Alejos, Elisa Martinez Orbea together with Fiodar Morau and Aliaksei Ashukha, Imaguru developers.

An application for walking dogs based on the blockchain platform with social interaction. The app creates a reliable and validated network to connect people who have to walk dogs with people who can offer such services. The user uploads his ride request in the app and then receives confirmation from another user who can offer the ride at the agreed time.

With the help of smart contracts users can create on demand time tokens to create a contract for the necessary time (half an hour, an hour, etc). The tokens are used for the validation of the ride and rewards. The app allows you to create dog profiles and evaluate them.

The Finalist Teams

(Second Prize, 1 ETH)
A blockchain solution for the electricity market. Using a decentralized solution, communities can create their own energy markets, reducing their costs and minimizing their dependency on the electricity system market. The application connects generators with consumers, determining the best combination of transactions from the point of view of their technical and economic viability. This combination of transactions is validated by the participants in this community market with blockchain.

Team Members: Pablo Jimenez, Andrés Badia, Mercedes Jul, Santiago Peñate, Pablo Gonzalez and Nuño Valencia.

(Second Prize, 1 ETH)
A blockchain application for exchanging airline miles and airline tickets. It is a market place that connects sellers with buyers and, with smart contract, validates transactions between them. The user can offer his ticket with the price in Ethereums and another user who has miles can buy it. The platform guarantees security, gives independence from airlines, travel agencies, etc. and gives the possibility to save on tickets.

Team Members: Adalberto Abade, Emilio Plá Escudero, Luis Campoy Sánchez, David Calap Bayarri and Emilio José Ocampos Alvarez.

DOP Dapp
(the winner, 3 ETH)
Formed by Alejandro Saiz Otero and Carlos Marchena who developed the decentralized application for food products.

It is a smart supply chain built with Hyperledger Fabric that serves to track the origin and all the way of each ingredient of a food product. The application is developed with Hyperledger Fabric, which consists of a semi-private network with different access levels for different roles. In this way you can add users with different levels of privileges: for example, the customer who buys the product in the store can only see the path of the product, the worker can also change the status of the product within the network and the admin can create the different user levels and see all the information within the network. With the help of QR codes, we can see when the product was produced and all the way to the store.

One of the ideas of how to make the traceability was to create a cookie in a 3D printer, print the last 4 digits of the hash with a laser and put them inside the product.

We are very happy with the work done and hope that all the teams will continue to develop their ideas (at least, that’s what they told us after the hackathon!).

We, Imaguru Startup HUB, are also moving forward with blockchain hackathons, courses and meetups to expand the technology community and create more projects. Next time when you come to our space, be careful because there may be unicorns inside!
