feat: add gas costs to TxEffect by just-mitch · Pull Request #5337 · AztecProtocol/aztec-packages

just-mitch · 2024-03-20T15:58:43Z

Built to the description provided in the yellowpaper changes.

TLDR: Adds da_gas_used throughout the kernel circuits, and includes it in the TxEffect that gets published, as well as the TxReceipt. See the token contract e2e test for end flow.

Immediate future work is to update/accumulate the gas during public kernel execution. See #5507

Fix #4101
Fix #5306

yarn-project/prover-client/src/orchestrator/block-building-helpers.ts

  const rollupOutput = await simulator.baseRollupCircuit(inputs);
+  const txEffect = toTxEffect(tx);
+  const txEffectHash = txEffect.hash();
+  if (!rollupOutput.txsEffectsHash.toBuffer().equals(txEffectHash)) {


Just flagging: I believe at present this would kill the whole proving ticket, which is probably not the behavior we want when one TX is invalid.

This addition at least enables a "fail fast" in that the ticket gets killed as soon as it knows that a single transaction would have invalidated the block, instead of waiting until the after the root rollup runs.

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.

Values are compared against data from master at commit f7e6cc86 and shown if the difference exceeds 1%.
