摘要： A method for maintaining a log of events in a shared computing environment is provided. One example of the disclosed method includes receiving one or more data streams from the shared computing environment that include transactions conducted in the shared computing environment by a first entity and a second entity that is different from the first entity. The method further includes creating a first blockchain entry for a first transaction conducted in the shared computing environment for the first entity, creating a second blockchain entry for a second transaction conducted in the shared computing environment for the second entity, where the second blockchain entry includes a signature that points to the first blockchain entry, and then causing the first and second blockchain entries to be written to a common blockchain data structure in a database that is made accessible to both the first entity and the second entity.
