We should release a tag as we do for halo2_proofs. Otherways this might be hard to track in the future.

Just thinking out loud to @CPerezz. Wondering what interface can we add to keccak config to simplify this gate.

I thought the same! ahhahah
That's why I wanted to meet with you. Since we can do a proxy-table to simplify the API (at a cost obviously). And I thought that once the state_tag stuff is handled (I'm working on it), We should meet with @miha-stopar and @ed255 to see what are they expecting exactly as API.

Implement the Tx Circuit as specified in https://github.com/appliedzkp/zkevm-specs/blob/master/specs/transactions-proof.md#circuit-behaviour-shortcut-1 This implementation uses ~205 columns and ~170k rows per transaction. New dependencies to the zkevm-circuits subcrate: - `halo2wrong` subcrates. This is where the ECDSA verification chip is implemented. This dependency uses `halo2` and this means that we'll require the version of `halo2` used in `halo2wrong` and `zkevm-circuits` to match. - `group`: Required for field and curve traits - `libsecp256k1`: Requiered to perform the ECDSA public key recovery with access to the public key coordinates. - `rlp`: Required to calculate the RLP of the transaction to get the transaction hash (to sign) - `num-bigint`: Used to hold an integer bigger than the field, to latter apply mod Fq (this is required for the message hash in the ECDSA signature operation) - `subtle`: Used to map `CtOption` to `Result`

k=19, which use a lot of memory even using the MockProver. Rust tests run in parallel by default, which may make the tests run out of memory when the tx_circuit tests are run concurrently with other tests. For this reason I've split the tests into "light" (which are all the test declared previously), and "heavy" which are marked with ignore and start with "serial_" and are run in a different step in serial both in the github actions and Makefile.Notes on current implementation:
