Show HN: Craft.cash – Minecraft on Bitcoin

This encodes voxel data in a binary format using OP_RETURN outputs of bitcoin transactions. With this design we can then look back into time to construct a world up until any Bitcoin block, effectively creating an immutable decentralized voxel world. Using BitDB and BitSocket as a "backend" to query for transactions we can keep our map updated with any changes, making it semi-real-time as well.

I'd love to hear any feedback. This project was very fun to develop and is completely open source if you want to take a peek at how it is implemented.

It's things like this that clearly demonstrate the power of a blockchain. It should also serve as a reminder that if you allow your blockchain to scale, smart people will make it useful, thus giving it value.

As much as I love good old BTC, the entire ecosystem seems to have gone stagnant the past few years. Meanwhile, I can't even keep up with all the new stuff being built on Bitcoin Cash.

Apparently BCH now supports tokens too. I just hope the devs don't lose focus and will continue building "peer to peer digital cash" as described in the Bitcoin whitepaper.
