A computer apparatus, such as a validator node, for validating incident-related data records in a distributed electronic ledger is configured to receive a request from an agent to add a proposed incident-related data record associated with an incident to the distributed electronic ledger. In response to the proposed incident-related data record, the computer apparatus determines, from the distributed electronic ledger, one or more attributes of the agent or incident. The computer apparatus determines whether the proposed incident-related data record satisfies validation criteria based at least partially on the one or more attributes of the agent or incident. Once validated, the computer apparatus may then append the proposed incident-related data record to the distributed electronic ledger. Alternatively, the proposed incident-related data record may be appended regardless of validity, but an indication of validity may be appended if the proposed incident-related data record is validated.
