Yep
2,973 projects submitted to Colosseum’s World’s Fair 🎡
A new record.
I put them all in one image.
Tomorrow’s unicorns are tiny squares today.
Bullish on builders. Bullish on Solana.

Thanks for the shoutout 🙌❤️
Feels good to finally get some recognition 🫶
The @colosseum Crypto World’s Fair hackathon received 2,973 project submissions! 🎡 Over the next few days, I will share a summary of each category. First up: DePIN.
Here is my selection of the most interesting projects you should keep an eye on: 👇🧵
@openroboto - robot training data with verifiable on-chain provenance and licensing
@uavdotfun - drone prototypes with a dApp that shares drone revenue with the community
@computecompany - verifiable AI chip where anyone can re-check every result, plus a market to rent it
Colpero from @luca_trevisani - one shared map for robots and drones, with camera-based position checks against GPS spoofing
@captur_go - Upwork for physical AI data collection
@sanfdn - live search API for AI agents, powered by a network of real browsers
@Evoracharge - GPU nanoclouds deployed at idle energy sources like biogas plants
Honourable mention:
@HaLoWaveNetwork
@DePin_Chest
@hydrx_protocol
Did I miss a project that deserves a spot? Drop it in the comments 👇
bringing urban water conservation on-chain with @MeteoraAG Dynamic Bonding Curve! 💧
Using Meteora DBC + DAMM v2, we enable automated price discovery & liquidity graduation for real-world water credits.

Every litre of physical water usage
Into verifiable data on @solana powered by @magicblock with 0$ tx fee .

HydrX Hardware Build :
The prototype stack:
→ ESP32 as the controller
→ YF-S201 to measure water flow
→ LCD for live readings
The goal: turn physical water conservation into verifiable on-chain data.

Water is wasted because nobody gets paid to save it. Hydrax fixes that. Real flow sensor → on-chain water credits.

Cape Town 2018.
Chennai 2019.
Bengaluru 2024.
Different cities, same hidden problem: families who save water get nothing for it.
No reward. No record. No proof.
we wrote about fixing this with HYDRX 👇

It's 2050. Tokenization won. Nobody calls it that anymore. They just call it "the receipt."
Here is one morning in INDIA , and one asset: Meera's water. 🧵
What changed wasn't the water. It was the proof.
When proof is free, saving becomes a job anyone can do. In 2050 nobody "invests in tokenization." They just get paid for being careful.
This isn't pure fiction. A first version exists today: HydrX, water-saving meters on Solana.
