About
About the challenge
HACKSPHERE 2026 is the flagship international hackathon of Computer Science Atmosphere (COMPSPHERE), organized by the Student Executive Board (BEM) of the Faculty of Computer Science at President University.
This year, we invite visionary minds to explore our grand theme: "Web3 Innovation". The challenge is to move beyond conventional centralized applications by integrating core Web3 elements (such as decentralized authentication, advanced cryptography, immutable databases, or smart contracts) to solve rigorously validated real-world problems. (Note: Creating crypto tokens or DeFi instruments is NOT required). Teams are highly encouraged to build Hybrid Tech Stacks by blending Web2 architecture with Web3 elements and Artificial Intelligence (AI).
This is a Two-Phase Hybrid competition:
-
Phase 1 (Online Preliminaries - The Filtering): A 100% conceptual round focusing on research sharpness and technical strategy. No programming code is required yet. Teams must submit a comprehensive, data-driven Idea Proposal (PDF) via Devpost.
-
Phase 2 (Offline Execution - The 24-Hour Final): Only the Top 30 teams will advance to a grueling 24-hour coding marathon and Live Pitching session. Teams must build a fully functional Minimum Viable Product (MVP) based strictly on their Phase 1 proposal. This phase is held physically at President University in Cikarang, Indonesia, with virtual/hybrid teleconference options provided specifically for Full International and International Mix Teams.
Get started
-
Step 1: Read the Rules & Download Templates: Download and thoroughly read the Official Hacksphere 2026 Guidebook to understand the complete rules, prohibitions, and judging criteria. You must also download the Proposal Template (.docx) from the "To-dos" section to draft your submission.
-
Step 2: Register & Build Your Team: Create a Devpost account and enroll. You must form a team consisting of exactly 3 members. (Solo registrants must find teammates via our Discord server before submission). Participants must be active High School/Vocational students or University Undergraduates between the ages of 15-25.
-
Step 3: Select Your Category: Ensure your team aligns with one of our three official categories: National Team, Full International Team, or International Mix Team.
-
Step 4: Join the Compsphere Discord Hub & Post Twibbon: Every member must join the official COMPSPHERE Discord server and rename their profile to [TEAM NAME] - [PARTICIPANT NAME]. Additionally, all members must upload the official Twibbon to Instagram (the link to this post must be submitted with your proposal).
-
Step 5: Submit Your Proposal (Phase 1): Upload your finalized Idea Proposal (PDF format, max 10 MB) to the "Additional Info" section on Devpost before the strict deadline on September 18, 2026, at 23:59 WIB (GMT+7). Remember to strictly follow the file naming convention (e.g., [TEAM NAME]-[PROJECT NAME]-NATIONAL.pdf).
Requirements
What to Build
-
Web3 Infrastructure Solutions: Your project must align with the "Web3 Innovation" theme by integrating core Web3 elements (e.g., decentralized authentication, advanced cryptography, immutable databases, or smart contracts) to solve rigorously validated real-world problems. Creating crypto tokens or DeFi instruments is NOT required.
-
Industry Sectors & Real-World Use Cases: You have absolute freedom to choose your industry sector, such as Healthcare, Education, Agriculture, Green Energy, or Smart City infrastructure. You can utilize blockchain architecture to solve practical issues like healthcare records, supply chain logistics, public services, tamper-proof voting systems, decentralized digital identity, or intellectual property tracking. You must back your problem statement with real data, statistics, and actual field facts rather than mere assumptions.
-
Platform Flexibility: You have complete freedom to determine your product's delivery platform, including Web-based applications, Mobile apps (iOS/Android), or Internet of Things (IoT) hardware ecosystems.
-
Hybrid Tech Stack Integration: We highly encourage blending traditional Web2 architecture with Web3 elements, as well as integrating Artificial Intelligence (AI) for features like data analysis, prediction, or automation.
-
The Strict "Functional MVP" Rule: You must build an original, fully functional MVP strictly during the 24-hour Phase 2 coding marathon. Presenting a prototype that relies on hardcoded data, pure UI mockups without a genuinely running backend, or using pre-existing projects created before the hackathon is strictly prohibited and considered a severe violation of technical integrity.
What to Submit
- Phase 1 (Online Preliminaries - Required for All):
-
Idea Proposal (PDF): You must submit a 100% conceptual Idea Proposal in PDF format (maximum size 10 MB) to the "Additional info" section on Devpost.
-
Mandatory Template: You MUST download and use the official Proposal Template (.docx) from the "To-dos" section. Your PDF must strictly follow this anatomy: Executive Summary, Data-Driven Problem Statement, Proposed Solution & Value Proposition, MVP & Key Features, Target Market & Impact Viability, and Tech Stack & System Architecture.
-
Strict File Naming Convention: You must name your file based on your team category: [TEAM NAME]-[PROJECT NAME]-NATIONAL.pdf, [TEAM NAME]-[PROJECT NAME]-INTL.pdf, or [TEAM NAME]-[PROJECT NAME]-MIX.pdf.
-
Twibbon Requirement: The link to your uploaded Instagram Twibbon post must be submitted alongside your Phase 1 Devpost idea proposal.
-
- Phase 2 (Offline Execution - Required for Top 30 Finalists):
-
Public Repository Link (GitHub/GitLab): A link to your public code repository must be submitted as evidence of your hacking commit history strictly over the 24-hour period.
-
Presentation Slide Deck: A presentation deck in PDF or PPT format (maximum file size 10 MB) to be used during your 10-minute Live Pitching session.
-
Live Deployment URL (Optional but Recommended): A link to a deployed, hosted version of your MVP (Cloud, Testnet, Web3 Public network). Deploying to a public network yields major consideration points over demonstrating purely via Localhost.
