A multi-version database includes user-defined blockchain containers, where each of the user-defined blockchain containers is configured based on a type of data to be stored in a corresponding user-defined blockchain container. Each of the user-defined blockchain containers includes a set of one or more fields defined by a user. A command to write data to the multi-version database is received, where the command includes an identification of a first blockchain container of the user-defined blockchain containers, an identification of at least one of the set of one or more fields of the first blockchain container, and a value to write for at least one field of the set of one or more fields. A record is generated for the first blockchain container, the record including the value to write for the at least one field. A current state of the first blockchain container is then updated to include the record.
