Reputation tokens based on user activities in virtual worlds

One or more non-transitory computer-readable media storing instructions that, when executed, cause:

• receiving, by one or more computing devices and from a user associated with a user device, a first request to access a virtual world;
• executing, by the one or more computing devices, with one or more blockchain networks, and based on the first request, a blockchain transaction indicating granted access to the virtual world, wherein the blockchain transaction comprises a first timestamp indicating when the user has started interactions with the virtual world;
• determining, based on a second blockchain transaction, a second timestamp indicating when the user ceased accessing the virtual world;
• and
• based on data, from the one or more blockchain networks, indicating that the user has violated, after the first timestamp and before the second timestamp, a predetermined rule from one or more rulebooks associated with prohibited activities in the virtual world:
• executing a fourth blockchain transaction to reduce a quantity of reputation tokens by a penalty value;
• and
• denying a second request from the user to access the virtual world, wherein the data was generated based on processing, using a machine learning model, text provided by the user when participating in the virtual world.

A computing device comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the computing device to:
• receive, from a user associated with a user device, a first request to access a virtual world;
• execute, with one or more blockchain networks and based on the first request, a blockchain transaction indicating granted access to the virtual world, wherein the blockchain transaction comprises a first timestamp indicating when the user has started interactions with the virtual world;
• determine, based on a second blockchain transaction, a second timestamp indicating when the user ceased accessing the virtual world;
• and
• based on data, from the one or more blockchain networks, indicating that the user has violated, after the first timestamp and before the second timestamp, a predetermined rule from one or more rulebooks associated with prohibited activities in the virtual world:
