Systems, methods, and software described herein provide enhancements for managing data storage in a satellite platform. In one implementation, a satellite platform includes a plurality of satellites, wherein a first satellite of the platform is configured to identify a request for a ledger entry for a blockchain maintained by the satellite platform and, in response to the request, distribute the ledger entry to one or more other satellites of the satellite platform, wherein the one or more other satellites comprise full nodes for the blockchain. Once distributed, the one or more other satellites each determine whether the ledger entry is verified and, when the ledger entry is verified, enters the ledger entry in a ledger for the satellite.
