A Hackathon to shape Web3 innovation
CryptoXR, for its third edition, promises to be an unmissable event with more than 3,000 visitors, +70 speakers and an exhibition space of 6,000 m². Focused on the federation and democratization of Web3 technologies, the event brings together pioneers of the crypto industry, local players and the general public to celebrate innovation, inclusiveness and decentralization.
Alephium, thanks to its Proof-of-Less-Work technology and its stateful UTXO model, embodies a high-performance, secure and sustainable blockchain. This hackathon therefore offers developers a unique opportunity to create innovative solutions on a decentralized infrastructure capable of managing more than 10,000 transactions per second while respecting ambitious environmental objectives. As a result, the most functional, impactful and innovative projects will be rewarded in ALPH with attractive prices:
- 1st place: €3,000
- 2nd place: €2,000
- 3rd place: €1,000
Special prizes of €500 will reward creativity, user experience, code quality and security-enhancing projects. Additionally, solo developers will also have the opportunity to shine with a total prize pool of €3,000, including challenges such as porting Solidity contracts, solving puzzles, and creating tools for Alephium developers.
A rich and inspiring program
The hackathon will start on Friday January 31 with an onboarding session and shared resources to support participants. The competition will be in full swing on Saturday February 1, with an awards ceremony on the main stage at 8 p.m.
