The concepts and technologies disclosed herein are directed to providing a split ledger for securing extended reality (“XR”) environments. According to one aspect, an XR server computer can create an XR environment. The XR server computer can cause a passed ledger to be populated with an environment ID associated with the XR environment. The XR server computer can cause a hash ledger to be populated with a first hash of the environment ID. The XR server computer can register a user for participating in the XR environment and can cause the passed ledger to be populated with a user-created block associated with the user. The XR server computer can cause the hash ledger to be further populated with a second hash of the user-created block. The XR server computer can allow a user avatar associated with the user to join the XR environment.
