It's already working, but not ready. On join.skyroad.me, you can test the parkour game that is based on HiveCraft. It loads worlds from the blockchain and stores speedrun times back to the blockchain.

To get there, you need Vanilla Minecraft 1.13.2 - 1.16.1 and join the server, there, type in /jnr. At this place, players can sync up their Hive Wallet using /hiveconnect hiveusername, once done, they can publish their own times, maps and also get rewarded for it. 👍

It's just not stable yet and there are missing some features.
