Introducing World Computer Hacker League: Four-Month Global Competition to Build Next-Gen Apps

Developers worldwide will embark on an unparalleled journey with direct mentorship from blockchain pioneers, global community support, and pathways to funding.

Following announcements made at the World Computer Summit 2025, the DFINITY Foundation, the main contributor to the research and development of the Internet Computer, and the ICP HUBS Network – the global community driving the Internet Computer adoption – are launching the World Computer Hacker League 2025 (WCHL25): a four-month global hackathon challenging developers to build production-ready applications on the Internet Computer technology.

The competition, running July through October with registrations now open, is primed to offer an unparalleled experience for builders by granting access to all valuable resources and incentives necessary to accelerate their journey. 

Participants will receive weekly mentorship and feedback from technical experts and experienced builders, ensuring continuous growth and guidance throughout the hackathon. Comprehensive technical support is available through workshops, office hours, and in-depth explorations of the ICP tech stack. Developers also benefit from the exposure to a well established global network of stakeholders, alongside opportunities to pitch their projects to leading Web3 venture capitalists and angel investors.

Unlike traditional hackathons, WCHL provides four months for teams to focus, develop, test, and deploy fully functional applications on the Internet Computer blockchain. The extended timeline enables developers to create more genuine products rather than proof-of-concepts, addressing the industry’s well known challenge of translating hackathon projects into sustainable ventures.

“WCHL gives developers what they’ve been asking for: real time to focus and build, real support from experts, and real pathways to growth,” said Emilio Canessa, Director of Global Adoption at DFINITY Foundation. “We’re not just running a hackathon, we’re creating the environment developers need to succeed. Most importantly, we want this event to be an unforgettable experience for tens of thousands of builders around the World.”

In addition to a globally open track, the hackathon leverages a consolidated audience of developers from the ICP HUBS Network – which spans across  North America, South America, Europe, Africa, and Asia and revolves around four stages.

Participants will be challenged to build fully functional applications that run on the Internet Computer blockchain and will go through 4 rounds of selections. The Qualification Round, where teams submit their ideas and qualify to participate; the National Round, where 30% of the teams will be selected; the Regional Round, which brings together top teams on a Continental level; and the Global Grand Finale, where the best projects will compete for top prizes and honors on a global stage.

A panel of judges including prominent members of the ICP ecosystem and industry experts will be evaluating projects based on technical execution, user experience, and real-world applicability.

Registration opens today at DoraHacks. Join now, and become a pioneer in shaping the future of the internet.

About the Internet Computer

The Internet Computer (ICP) represents a fully decentralized web3 cloud platform, enabling developers to deploy code directly onto the blockchain without relying on servers or centralized infrastructure. This fast, cost-efficient, and highly scalable protocol redefines the operational paradigm of a decentralized web3 platform. ICP offers the same functionalities as centralized clouds but with economically efficient computation, heightened security, and rapid processing speeds intrinsic to decentralized technology.For more information, please visit: Internet Computer website | wchl25
