## Description

This is a project demo as part of the MUD Day CLS: autonomous worlds, onchain games, and non-financial applications.

Biomes is growing the virtual world with the largest GDP. As a fully onchain 3D voxel world, every single action in Biomes -- mining, building, crafting, even moving -- is a transaction on the Redstone L2.

## Transcript

[Music] okay it's working so yeah hey everyone I'm davani from biomes and I'll start again so we believe a crazy new asset class enabled by digital matter and smart items will unlock autonomous worlds so if you haven't heard about biomes biomes feels and looks just like Minecraft with everything on chain for the first time ever so not just assets but items players physics all the actions even movement is fully on chain and this is not on a test net it is live on vetone the L2 ethereum main net you can try it today so if I just you know I can move around in the world um I can WD around I can mine I can build I can craft like all the things you'd expect from Minecraft um we have working and it feels just like Minecraft we almost par ux okay so then what's different so the main thing that's different inside of the world is smart items smart items are basically items that have regular functionality in the game like a chest where you can store items take stuff out but you can augment them with a smart contract and now that item will behave based on the smart contract so as a concrete example we have a Unis swap like chest which is basically a chest um with a the Unis swop smart contract which which makes it so you can only take stuff take items in and out if you transfer tokens and now you have basically like a third party shop that behaves based on this smart contract and the design space for these smart contracts is kind of w because it's a regular smart contract that any player can write so already since like ala release a couple weeks ago we've seen a couple of smart items being created inside of the world so I'll just go around the world and show you a couple so the first one I mentioned was that Unis swap like smart uh smart item and so this is one of the main bazaars in a game where people are buying and selling items and as you can see like when I go up to a chest I can't just take the items out I sort of have to interact via this UI which lets me pick how many wood I want to buy which is the Sakura wood which is this new like uh rare wood that rare religion that's forming inside of the community um and you can see it's given me like the current Dynamic price for this wood so now I'm going to go into spectator mode so I can fly around and show you a couple of more interesting smart items so just beside this like main Bazaar one of the gaming guilds who's been playing actively has created their competitor Bazaar right beside us it's kind of like the shy swap of biomes they have their own pricing and fee mechanism but they're doing a similar thing of buying and selling items using a chest now you might ask well why can't I just mine this chest and take all the items um and that's because we have another smart items which is a force field Tower and when you have a force field Tower you can again use a Smart contract to control permission for who can build and mine inside of your area and as and the main thing to know is that compared to other um like decentralized like projects where they have land sales for nfts that control permissions um with biomes you can't control the land forever to control your land you have to use this in-game item which is the force field Tower and you have to charge it using batteries which is another in-game item and so all of these smart items function via batteries and as long as the batteries charge it will work but players can rebel by by damaging the battery and making the smart item no longer work so just two other cool very interesting smart items players have created um one of them is this Sakura holy tree so there's four kinds of wood in biomes but one of them them which is the Sakura wood has become kind of memed and everyone sort of rallying around it and so this player wants to build this like giant Monument of the biggest sakura tree but he needs a lot of Sakura logs and they're hard to get to take over a year to grow and so he created this chest where you donated a 100 like Sakura logs which will he which will he which he'll use to create this tree and in return He mins you this like nft and or we call them passes inside of biomes and this pass Gates access to his like um like to use all of the like go inside of his buildings other events he's going to run and so by donating your wood you sort of getting access to all of those things he's going to use in the future in a similar sense another user another gaming guild has created their own like hotel where they sort of have beds and rent out like for people to sleep inside and to access it to become a part of their Guild you have to get to their chest and you have to again transfer a couple of items to get their passed and once you have their pass pass you can now access all their things um the last thing I'll show is not a like a a p uh it is a pass but it's not about just transferring items but it's actually about parkour because now we have like real time movement you can actually um oh it's the chunk itself is not loading um but over here we have basically um a place where players can play parkour and you get to the top of the parkour you get to again mint a pass by interacting with the chest and only players who get to the top can interact with it because that's where the the uh the actual chest is and yeah so that's pretty much it we think smart items can birth an asset class enabled by and on the virtual world's physics um we have a talk later uh in the afternoon so come by to hear more about it thank you
