1. An access-control system, comprising:
one or more processors; and
one or more non-transitory machine-readable storage media containing instructions that, when executed on the one or more processors, cause the one or more processors to perform operations including:
associating a first key share with first data, wherein the first data is stored by a first computing device;
associating a second key share with second data, wherein the second data is a copy of the first data and is stored by a second computing device;
computing a hash chain for the first data using at least the second data;
determining versioning information corresponding with the first data, the versioning information including at least the hash chain for the first data and a location of the first data;
recording the versioning information corresponding with the first data on a distributed ledger accessible by the first computing device and the second computing device for verifying one or more copies of the first data; and
managing access to at least one of the first data or the second data using the first key share and the second key share.
