Q:

what should be expected if i tamper the h2 database in corda?

what happen if i tamper the data in h2 database
I have  tampered with some hex strings but corda continued to work without any problem. i don't understand, how is that possible?
thanks in advance

A:

It really depends on what is being tampered with.
If you tamper with the ID of an input state, for example, then other nodes should reject transactions involving that state.
However, if you modify the hash of an attachment stored locally, you will only be affecting yourself (and any other nodes you share the attachment with). The issues could not become evident for some time.
