Abstract: A blockchain insurance verification system obtains information for one or more policies and/or updates to such policies related to one or more insureds and stores such information in one or more blockchains. The information may detail the risk that is covered, the limits of the coverage, conditions of the coverage, endorsements and/or exclusions to the coverage, and so on. The information may also include an indication of an authentication strength level, which may correspond to the entity who provided the information and/or verified the accuracy of the information. The system may be usable to store such information in an unalterable but updatable way, provide such information, connect one or more parties looking to provide and/or obtain such information, verify such information, determine an authentication strength level of such information, determine one or more sets of requirements, compare such information to one or more sets of requirements, provide notifications, and so on.
