On March 1st and 2nd, 2025, 01node and Buidly, in partnership with Comets of Web3, hosted the Build on Sui: Technical Workshop in Bucharest, Romania. The event, supported by the Sui Foundation, brought together over 150 blockchain builders for an in-depth exploration of the Sui Network, Move programming language, and Web3 innovations.
March 1st: The Builders Event
📍 Time: 6:30 PM
📍 Location: Bucharest
The Builders Event served as a networking hub for Romanian blockchain developers, featuring 01node, CryptoExpoEu, Sui Foundation, and Buidly. The event provided Web3 builders, developers, and founders an opportunity to connect, collaborate, and explore new ventures in the Sui ecosystem and beyond.
March 2nd: Sui at Crypto Expo Europe
📍 Time: 12:30 PM
📍 Location: CryptoExpoEu
During CryptoExpoEu 2025, Sui Foundation took the stage for a 20-minute spotlight session, showcasing the Sui Network’s speed, scalability, and security features. The session also introduced the SuiOverflow 2025 Hackathon, offering developers a chance to compete and innovate within the Sui ecosystem.
March 2nd: Sui Technical Workshop
📍 Time: 4:00 PM
The Sui Technical Workshop was a deep dive into smart contract development using Move on Sui. Led by Alex Tsiliris from Sui Foundation, the workshop covered:
✅ Sui’s unique object-based architecture and how it differs from traditional blockchains.
✅ Move programming fundamentals, including ownership models, transaction efficiency, and gas fee optimizations.
✅ Building scalable and secure smart contracts on Sui.
✅ Best practices for developers ahead of the SuiOverflow 2025 Hackathon.
Key Takeaways from the Sui Technical Workshop
- Sui’s architecture optimizes transaction execution by distinguishing between owned objects (fast transactions) and shared objects (consensus-required transactions).
- Gas fee optimizations allow developers to reclaim storage costs when objects are deleted.
- Move’s security model eliminates vulnerabilities common in Solidity-based smart contracts.
- Dynamic fields in Move enable scalable object structures, ensuring better long-term contract flexibility.
- SuiOverflow 2025 Hackathon was introduced as a major opportunity for developers to build and showcase their projects.
Event Impact and Community Growth
This event marked a significant milestone for Romania’s Web3 community, with key contributions from Sui Foundation, CryptoExpoEu, Buidly, 01node, and CometsOfWeb3.
- Daiana Marculescu introduced the Comets Experts Program, a new initiative connecting builders with Web3 projects.
- The event strengthened Romania’s blockchain ecosystem, providing networking and collaboration opportunities for developers, investors, and entrepreneurs.
- The workshops and discussions set the stage for new projects and potential collaborations in the Sui ecosystem.
Final Thoughts
The Build on Sui: Technical Workshop and CryptoExpoEu 2025 successfully brought together blockchain builders, investors, and industry experts to explore the future of Web3. With a growing developer community, an expanding ecosystem, and upcoming hackathons, Sui continues to establish itself as a key player in the blockchain space.
We loved the event—and we hope you did too! 🚀
