Koimitsu is an on-chain Koi fish collection game that combines concepts from CryptoKitties and Axie Infinity, but achieves a fundamental difference through Zama's fully homomorphic encryption(FHE) technology:

The core innovation lies in — attributes and data are completely hidden at the time of minting and are gradually revealed throughout the lifecycle. From egg(Egg) hatching to fry(Fry), juvenile(Juvenile), and adult(Adult), each stage progressively discloses your Koi's true attributes.

This mechanism changes the gameplay logic of traditional NFT games. It is no longer just about minting to see, but filled with discovery and anticipation. The combination of privacy protection and gaming experience is very clever — utilizing FHE technology to process data on-chain, ensuring transparency while preserving surprises.

Wow, this setting is amazing. The attribute hidden until later stages? Really brings the feeling of opening blind boxes onto the blockchain. Wait, can FHE encryption really guarantee that data won't be cracked in advance... or is this just hype? It's a pretty interesting gameplay innovation. Compared to those projects where everything is fully transparent after minting, this is definitely more fun. Another project using FHE as a selling point. This time, it's not just about privacy concepts anymore. Koi fish... the theme choice is a bit odd, but I like it. NFT games with a sense of discovery are generally lacking, and I think this idea works.

Wow, this hidden attribute setting is pretty interesting. Finally, a game has thought of using privacy technology to create suspense. Gradual attribute unlocking? It feels a bit like opening a blind box. This approach is definitely more fun than just looking at the data directly. But can FHE run on-chain? Will the gas fees be completely drained? This is the kind of NFT game it should be—much better than those boring transparent projects. Finally, someone has combined privacy and gaming. In the past, these encryption technologies were just wasted.

Wow, now that's what I call innovation. I'm tired of those things that can be seen through with just one minting. This step-by-step attribute unlocking design is so exciting.

actually... fhe being applied to nft metadata reveal mechanics is kinda interesting but let me be real, most people won't even understand what's actually happening under the hood here. they'll just see "ooh hidden attributes" and treat it like a loot box simulator. the computational overhead alone should worry anyone paying gas fees tbh
