Cryptographically transmitting and storing identity tokens and/or activity data among spatially distributed computing devices

A computing device comprising:

• a processor;
• and
• memory storing computer-executable instructions that, when executed by the processor, cause the computing device to:
• receive first identity data associated with a user;
• generate, based on the first identity data associated with the user, a first identity token for the user;
• transmit, to a plurality of other computing devices, the first identity token for the user;
• determine a number of computing devices, of the plurality of other computing devices, that verified the first identity token;
• based on a determination that the number of computing devices is above a threshold number of computing devices, store the first identity token for the user in an identity chain, wherein the first identity token for the user indicates a prior identity token stored in the identity chain;
• receive a request to perform an activity;
• in response to the receiving the request to perform the activity, request second identity data associated with the user;
• receive the second identity data associated with the user;
• generate, based on the second identity data associated with the user, a second identity token for the user;
• based on a comparison of the second identity token to the first identity token, authenticate the user and generate an activity token for the activity;
• and
• store the activity token for the activity in an activity chain, wherein the activity token indicates a prior activity token stored in an activity chain.

A non-transitory computer readable medium storing instructions that, when executed by a computing device, cause the computing device to:

• receive first identity data associated with a user;
• generate, based on the first identity data associated with the user, a first identity token for the user;
• transmit, to a plurality of other computing devices, the first identity token for the user;
• determine a number of computing devices, of the plurality of other computing devices, that verified the first identity token,
• based on a determination that the number of computing devices is above a threshold number of computing devices, store the first identity token for the user in an identity chain, wherein the first identity token for the user indicates a prior identity token stored in the identity chain;
• receive a request to perform an activity;
• in response to the receiving the request to perform the activity, request second identity data associated with the user;
• receive the second identity data associated with the user;
• generate, based on the second identity data associated with the user, a second identity token for the user;
• based on a comparison of the second identity token to the first identity token, authenticate the user and generate an activity token for the activity;
• and
• store the activity token for the activity in an activity chain, wherein the activity token indicates a prior activity token stored in an activity chain.
