Data quality and integrity are core needs but also resilience to failures and manipulations. The core idea of this paper is to use dis-tributed ledger technology to allow for a secure information exchange between Command and Control Information Systems of different NATO nations and non-NATO stakeholders such as non-NATO nations or mission observers. Moreover, the distributed ledger supports available NATO standards and formats for da-ta exchange and storage.enfalseBlockchainCoalition OperationsDistributed LedgerInformation ExchangeTactical Levelconference paper
