feat(avm): new public inputs witgen by IlyasRidhuan · Pull Request #10179 · AztecProtocol/aztec-packages

IlyasRidhuan · 2024-11-25T14:34:33Z

This PR does a few things

Disconnects the kernel trace constraints (but keeps the file for future reference when we re-constrain public inputs)
Replaces the old public inputs with the new ones from AvmCircuitPublicInputs, however unconstrained
All merkle checks are now performed in witgen

It's still a bit brittle and probably needs a refactor to clean it up but will suffice for now as we are getting all the pieces together

 namespace main(256);
+    //===== PUBLIC INPUT POLYNOMIALS ======================================


These are moved over to just keep the existing public inputs structure and is not representative of the final version

Were these copied from another PIL file? Should they be removed from their original file?

yeah - the old pil file (kernel.pil) is commented out - it will eventually be deleted entirely, but ive kept it because we will need to reference / copy stuff from it when we constrain the new inputs

    NONE = 0,
    BYTECODE_HASHING = 1,
    MERKLE_TREE = 2,
+    SILO = 3,


These will be used when we constrain silo-ing in the circuit

2^40 trees at this stage require bigger indices

Looks good! Handful of comments. I'd expect all the merkle checks in witgen to break for transactions that include side effects from private since (i think) you aren't inserting any of the stuff from private, so the start and end roots should be mismatched. How is this working?

-        return AvmExecutionTests::gen_trace(bytecode, calldata, public_inputs_vec, returndata, execution_hints);
+        auto p_i = public_inputs;
+        return AvmExecutionTests::gen_trace(bytecode, calldata, p_i, returndata, execution_hints);


nit: no need to rename to p_i here?

+    // These are the tracked roots for intermediate steps

We actually might need these in the future because we need to raise error flag if these surpass some limits.

some leftover formatting from master i think
