The ETH Dublin 2025 Hackathon has emerged as a landmark event in the blockchain innovation calendar, bringing together developers, visionaries, and industry leaders to explore the transformative potential of decentralized technologies. With 84 developers participating and 31 projects successfully accepted, the hackathon showcased the power of collaboration, technical excellence, and real-world problem solving through blockchain.
Organized by ETH Ireland, the event was more than just a coding competition—it was a catalyst for building scalable, impactful solutions that align with modern regulatory standards and societal needs. Backed by key technology sponsors such as Chainlink for data verification, Ledger for security, and Filecoin for decentralized storage, participants were equipped with cutting-edge tools to push the boundaries of what’s possible on Ethereum.
Driving Innovation Through Collaboration
At the heart of ETH Dublin 2025 was a clear mission: to foster innovation that matters. Participants formed balanced teams with diverse skill sets—spanning smart contract development, UX design, cybersecurity, and regulatory compliance—to build projects that go beyond technical novelty and deliver tangible value.
The hackathon emphasized real-world applicability, encouraging solutions that address pressing issues in privacy, public safety, housing, immigration, and education. This focus on social impact distinguished ETH Dublin from typical tech-centric events, positioning blockchain not just as a financial tool but as a force for inclusive progress.

Core Technologies Powering the Projects
Developers leveraged a robust ecosystem of blockchain infrastructure:
- Chainlink: Enabled secure and verifiable off-chain data integration.
- Ledger: Provided hardware-level wallet security for asset protection.
- Filecoin: Offered decentralized data storage solutions for transparent record-keeping.
- Ethereum: Served as the foundational layer for smart contracts and dApp deployment.
These tools allowed teams to build secure, scalable, and interoperable applications—proving once again that Ethereum remains a leading platform for next-generation decentralized applications (dApps).
Projects That Make a Difference
Many of the submitted projects demonstrated how blockchain can solve everyday challenges while adhering to legal frameworks like GDPR. Here are some standout examples:
ÉireEncrypt – Privacy-Preserving Blockchain Tools
ÉireEncrypt focuses on developing GDPR-compliant tools that protect user privacy without sacrificing transparency. By leveraging zero-knowledge proofs and encrypted data layers, the project ensures personal information remains private while still enabling auditability and trustless verification.
This kind of innovation is critical in sectors like healthcare, finance, and identity management, where data protection regulations are strict but digital transformation is essential.
SafeRoads Ireland – Promoting Safer Driving with Smart Contracts
SafeRoads Ireland introduces a decentralized system that uses smart contracts to incentivize safe driving behavior. Drivers earn reputation tokens based on verified driving records, which can be used for insurance discounts or access to premium mobility services.
By integrating real-time data feeds via oracles and linking them to automated reward mechanisms, SafeRoads shows how blockchain can improve public safety through behavioral economics.
RentRegulate & Decentralized Housing Markets
Several projects explored blockchain applications in rental regulation and property markets. These platforms aim to eliminate fraud, reduce bureaucracy, and increase transparency in tenant-landlord relationships by recording leases, payments, and maintenance logs on-chain.
Such systems could revolutionize urban housing management—especially in high-demand areas like Dublin—by ensuring fair access and reducing disputes.
Digital Solutions for Immigration & Community Integration
Another powerful theme was using blockchain to support immigrants and marginalized communities. Projects included digital identity systems that allow newcomers to securely store credentials and prove residency or employment history without relying on centralized databases.
These tools promote inclusion, reduce administrative delays, and empower individuals with control over their personal data—hallmarks of a truly decentralized society.
Hackathon Winners: Pioneers of Practical Blockchain Use
The judging panel recognized three outstanding projects that combined technical sophistication with real-world utility.
🥇 1st Place: RecEth
RecEth won top honors for enhancing user trust in cryptocurrency transactions. The platform introduces email-based confirmations and clear digital receipts—mirroring the transparency users expect from traditional payment systems like PayPal or bank transfers.
By bridging the gap between legacy finance UX and blockchain backend operations, RecEth makes crypto transactions more accessible to non-technical users. This kind of user-centric design is crucial for mass adoption.
🥈 2nd Place: Latinum
Latinum simplifies commercialization for Minecraft Pocket Edition (MCP) server builders. It enables creators to monetize their servers through agent-triggered events and compatible wallets—opening new revenue streams in the gaming metaverse.
With the rise of play-to-earn models and virtual economies, Latinum demonstrates how blockchain can empower digital entrepreneurs in niche ecosystems.
🥉 3rd Place: FundRaisely
FundRaisely leverages blockchain to help charities raise funds legally and transparently. Every donation is recorded immutably, allowing for clear audits and accountability—key factors in restoring public trust in nonprofit organizations.
The platform supports compliance with anti-money laundering (AML) regulations and provides donors with real-time tracking of how their contributions are used.
