Crypto-assurance provides guarantees against mutations, truncation, and reordering. Although ESDB doesn't provide nativa mutation and reordering capability, data on disk can be tampered to change the content of events. ESDB supports truncation with no option to disable the feature, which can break auditability of the event log where it is required.
By implementing crypto-assured streams, ESDB could become an alternative to products like Amazon QLDB.
