That’s a wrap! Thank you to everyone who joined us in Heraklion, Crete. Here’s how it went.
After the events in Antalya, Chain4Travel teamed up with Avra Tours and Cyberlogic for another Web3 hackathon, this time in the heart of Heraklion. In a relaxed setting of Greek hospitality and sea views, three teams of developers and travel experts built three working prototypes in just two days. Camino committed to supporting the teams beyond the hackathon and to feeding some of their ideas into the development of its own platform.
The prize: $CAM & honor.
Event-based travel at the push of a button. Travelers sign up for event categories; destination management companies worldwide feed the events into a decentralized database, and travelers automatically get matching hotels and offers near the venue. The app used Camino Network’s blockchain entirely through Camino Messenger, without touching the blockchain directly.
Smarter micropayments for travel bookings: a digital escrow that settles exactly what happens to payouts and commissions when a supplier or an intermediary cancels, avoiding the chain reactions of manual processes when several suppliers share one booking. The working demo ran on the Camino blockchain: travelers book with a digital wallet and receive an NFT as booking confirmation.
Faster refunds for airlines: one shared channel between travel distribution and suppliers, where smart contracts keep a single, verifiable record of every refund claim and its status. This prevents duplicate claims, allows payouts in digital currencies and could bring in digital identities and legal intermediaries to identify travelers.

sponsored by Universal Small bookings involve many hands: tour operators, local agencies, transfer and activity providers all keep their own copy of the booking, and splitting a small payment between them often ends in disputes and manual reconciliation. The challenge was to build a smart contract on Camino Network that shares each payment between all parties automatically and transparently.

Camino Messenger lets travel businesses talk to each other and trade directly, and this challenge asked teams to build something new on top of it.

“This hackathon shows once again how practical solutions that decisively advance the digitalization of the travel industry can emerge in a very short time. The ideas and implementations from Greece have enormous potential to make existing processes simpler, more secure and more sustainable, and we look forward to developing some of these approaches further together with our partners.”
