[codygunton]

Exposes a function to verify ClientIVC proofs through the Bb binary

Lgtm

Why underscore? Underscore signifies unused variable elsewhere in codebase

[codygunton]

err, here I meant that the variable is 'hidden' / about to be replaces, not sure better notation for that.

[codygunton]

I would rather just use a filter but I'm trying to get this in

Benchmark results

Metrics with a significant change:

• avm_simulation_time_ms (Token:mint_public): 335 (+494%)
• avm_simulation_time_ms (Token:transfer_public): 30.3 (-48%)
• protocol_circuit_proving_time_in_ms (base-parity): 1,398 (-31%)

Detailed results

All benchmarks are run on txs on the Benchmarking contract on the repository. Each tx consists of a batch call to create_note and increment_balance, which guarantees that each tx has a private call, a nested private call, a public call, and a nested public call, as well as an emitted private note, an unencrypted log, and public storage read and write.

This benchmark source data is available in JSON format on S3 here.
