     end up with pre root (the root of tree before proofs are generated), post root, start index and
     identity commitments (with their proofs). All of those get sent to a [prover](#semaphore-mtb) for proof generation.
     The identities transaction is then mined, with aforementioned fields and pending identities are sent to task to be mined on-chain.
     3. Mining:  The transaction ID from processing task gets mined and Sequencer database gets updated accordingly.
     Now with blockchain and database being in sync, the mined tree gets updated as well.

     indeed in the tree. The inclusion proof is then returned to the API caller.
 3. `/deleteIdentity` - Takes an identity commitment hash, ensures that it exists and hasn't been deleted yet. This identity is then scheduled for deletion.
 4. `/recoverIdentity` - Takes two identity commitment hashes. The first must exist and will be scheduled for deletion and the other will be inserted as a replacement after the first identity has been deleted and a set amount of time (depends on configuration parameters) has passed.
