This is what Playground . dot was made for.

Andrey Dodonov (14 years as a developer, PBA Campus 2025) was stuck in a 4-hour delay with a major German bank. So he built something.

A Proof of Delay app on testnet. Verify your delay on-chain. Generate a certificate. Stack your minutes in a game. An authentic, untamperable dashboard of delays that actually happened.

The next generation of apps comes from human experiences.

"You put people together, things will happen". This is one of the greatest mottos of late 2000s, the golden era of the collaborative internet. With the remix culture at its peak, everything looked bright and right.

Snowden papers came some years laters, bringing a huge and depressive dark cloud to the net.

Playground . dot at @Web3summit reclaims the same spirit but with renovated energy to fight what internet has become today. The Information Highway utopia, became a toll system to be paid with your attention, your rights and your money.

There is something at the end of the tunnel and it is not a train coming in the other direction.

Enter Playground . dot

A temporary, event-only demonet environment is being fired up for pure, unadulterated experimentation. It's a 2-day open workshop where you can explore a sandbox environment to create, modify, and share without the usual pains of dealing with decentralized infrastructure.

What you, your team, or your festival partners choose to spin up, modify, and remix inside this sandbox environment is 100% up to you.

Take an existing project, modify it, share it, and see what happens. It’s the raw energy of a hackathon inside a web3 culture festival.

DevCult will be on the ground to support builders - like you - digging into the demo apps. There’s no competition here; it is just a celebration of open culture, learning by doing, and a 4,750€ reward pool for builder teams pushing the tech to its limits.

🎖️Leaderboard winners - 1750 € pool between 1st, 2nd and 3rd

💕 Builder favourite app - 1000 €

👩‍💻 Crowd favourite app - 1000 €

💥 Wildcards for innovation and interesting use cases - 500 € wildcards x2
