Building Upgrade Bounty

This example project is currently deprecated while we update it for MUD v2.0.1. Much of the code will remain the same, but some breaking changes in the latest version require our attention.

Source code for the following example is available here (opens in a new tab).

Building Upgrade Bounty

building-upgrade-bounty is a world extension that enables the deployer to issue a private bounty for an outside party to upgrade the deployer's building on their behalf, in exchange for a reward.

Building upgrades cost resources, and it takes time to accumulate the necessary resources. There are some advantages of accelerating resource accumulation when you upgrade a building as soon as possible.

Let's look at two players, Alice and Bob. If Alice is going to be AFK and doesn't want to manage running a bot, she can create a building upgrade bounty and delegate the upgrade to another player, Bob, in exchange for a small reward.

• Alice deploys and registers namespace and private systems for extending game logic
• Alice delegates UpgradeBuildingSystem control to the private system
• Alice registers namespace access to Bob, Charlie, etc. to enable their participation in the bounty
• Alice deposits escrow (ETH) for the bounty in the private system
• Bob calls the private system to upgrade Alice's building
• Bob receives the bounty reward from the private system

Diagrams

For the above example, the delegation flow begins with Alice delegating the UpgradeBuildingSystem control to the private system and then registering namespace access to Bob.

Then, Bob calls the private system to upgrade Alice's building through the external system in the external namespace.
