@jimthematrix I don't feel the changes in the PR should have resulted in these PTAU changes. If you've upgraded Circom to v2.2.0 recently, that's likely to be the reason. adding --O2 will keep the same full form constraint simplification that we've been using and remove the need to update PTAU files as we default to using groth16. that's done as part of https://github.com/hyperledger-labs/zeto/pull/102/files#diff-9450c6f105ae987e3136ef62c143ea6d1baefd8a02e45bf3307fc0f781bdff01R154
I think for this PR, the PTAU file changes are not needed as the circom files are not on version v2.2.0

thanks for catching that. those are indeed resulted from the circom 2.2.1 update in my local environment, and not meant to be included. will revert that in a subsequent commit

Previously, once deposited, the single output UTXO's value is known because it's equivalent to the amount of the deposit. This PR makes the output to be an array, currently set to size 2 in the circuit.
