The concepts of fork consistency and fetch-modify consistency are pivotal in understanding the security guarantees provided by storage systems, particularly those involving untrusted storage servers. Both concepts address the challenges of ensuring data integrity and consistency in an environment where the storage server cannot be fully trusted. However, they do so in fundamentally different ways,
