Abstract
Aspects of the disclosure relate to a system and method for cryptographically transmitting and storing identity tokens and/or activity data among spatially distributed computing devices. The system may comprise a plurality of chains, such as an identity chain and an activity chain. In some aspects, identity data associated with a user may be used to generate an identity token for the user. The identity token may be transmitted to a plurality of computing devices for verification. Based on a verification of the identity token, the identity token may be stored in the identity chain. A request to perform an activity may also be received, and identity data associated with the user may be received in order to authenticate the user. The computing device may generate, based on the received identity data, an identity token for the user. The identity token may be compared to the identity token stored in the identity chain, and the user may be authenticated based on the comparison. An activity token for the activity may be generated, and the activity token may be stored in the activity chain.
