CeLatam's Participation in the Web3 Hackathon Colombia: Fostering Innovation

The recent Web3 Hackathon Colombia, held on December 2nd and 3rd at Jorge Tadeo Lozano University, stood as a pivotal arena for the convergence of technology and innovation in Latin America. CeLatam’s representation in this event not only underscored the commitment and talent of the participants but also the organization’s mission to drive technological solutions that generate a positive impact in the region, encouraging reflection, creation, and sharing of experiences within the web3 ecosystem in Latin America.

The first day commenced with a warm welcome to the participants, providing them with the Hackathon Swag, inclusive of CeLatam’s contributions as the Main Sponsor. Keynote speeches by experts such as Cristóbal Pereira from CeLatam, Thiago Monteiro from Metapool, Juan David Reyes, Angela Ocando, Esteban Villegas, and David Carvajal provided a comprehensive view from the judges’ and sponsors’ perspectives, offering valuable advice and insights for project development in a Hackathon. Each of these speakers contributed a unique and enriching perspective, spanning from strategic visions to practical tips, significantly enhancing the event and providing participants with a solid foundation for their projects.

Following a revitalizing lunch, the Hacking hours began, a period where mentors and hackers actively engaged in project conception and creation. This was a pivotal moment, witnessing how initial ideas were shaped and refined with constant mentor feedback, enabling projects to solidify with greater focus and purpose. During the night, some participants opted to rest, while others remained active working on their projects. This variation in time management strategies reflected the commitment and determination of the teams.

The second day was crucial for CeLatam’s participation. With reduced development time, many teams focused on the Celo platform, deploying solutions from financial inclusion to environmental sustainability. It’s worth noting that out of the total 13 projects presented, an impressive 77%, namely 10 projects, were successfully deployed on the Celo Blockchain. This focused approach resulted in a positive and enthusiastic response from the community, demonstrating the versatility and potential that the Celo platform offers for diverse applications.

The event’s climax arrived with the award ceremony, bringing together participants, mentors, and judges in a vibrant atmosphere while announcing and celebrating the winning teams of the Hackathon’s main prize. Each team had the opportunity to present its project, highlighting the effort and dedication invested during the event. Hours after the official closure of the ceremony, sponsors conducted a rigorous selection process to recognize projects that best utilized their products, thus announcing the winners of each of their awards in the following days. CeLatam’s bounty winners were DAgro, GreenGate, and Kiwi, who stood out for their innovative solutions and received a prize of 333 cUSD each, totaling 1k cUSD distributed.

GreenGate :seedling:

The GreenGate project arose from a profound understanding of current environmental challenges and a passion for ecological preservation. By merging Blockchain technology and NFTs, it aimed to provide access to natural parks while contributing to their conservation.

Technological Exploration:
During the development of GreenGate, in-depth research was conducted on the ERC721a standard to generate NFTs as access passes to natural parks. A comprehensive analysis of fund management was carried out, and mechanisms were implemented to ensure transparency in financial transactions.

Creation Process:
The created DApp allows users to acquire NFTs as entries to natural parks through a smart contract. Ensuring that a portion of each sale is allocated to conservation projects and community development.

Overcome Challenges:
The project faced challenges such as ensuring transparency in fund flow. An infrastructure was implemented that records each transaction on the Celo Blockchain, allowing real-time audits. Furthermore, a sustainable economic model was designed to support environmental projects and the operation of natural parks.

Impact and Future:
GreenGate represents a commitment to sustainability and innovation. It is a bridge between technology and the environment, with the potential to create lasting and positive change on the planet.
