zkEVM ProverJS

zkEVM proof generator reference written in Javascript

General info

setup

$ npm install
$ npm run build

Usage

Basic usage:

$ node src/main_executor <input.json> -r <rom.json> -o <proof.json>

Example:

$ node src/main_executor tools/build-genesis/input_executor.json -r ../zkevm-rom/build/rom.json -o tmp/commit.bin

Additional parameters:

  • -t <test.json>: test
  • -l <logs.json>: logs
  • -s: skip compile pil
  • -d: debug mode
  • -p: select pilprogram.pil
  • -P: load pilConfig.json file
  • -u: unsigned transactions mode
  • -e: skip asserts newStateRoot and newLocalExitRoot
  • -v: verbose mode PIL
  • -T: enable tracer
  • -c: disable zk-counters
  • -N <number>: override number of steps
  • -V <verbose-config.json>: verbode executor & full-tracer. Loads verbose-config.json
  • -S <stats.json>: save stats to a file

Verbose configuration

  • fulltracer.enable: prints events originated in the full tracer
  • fulltracer.printOpcodes: print opcodes
  • fulltracer.filterOpcodes: string filter when printing opcodes
  • fulltracer.initFinalState: print pre/post state of touched addresses
  • fulltracer.bytecode: add bytecode to pre/post state
  • fulltracer.saveInitFinalState: save file with pre/post state
  • zkPC: print info program counter
  • batchL2Data: print info about batch L2 data
  • step: print executor step

Build setup

npm run buildsetup --build=build/v0.7.0.0-rc.1 --bctree=../zkevm-prover/build/bctree

Build prove

npm run buildall

Build prove with basic main (without SM, only for debugging)

npm run buildall --pil=pil/basic_main.pil --starkstruct=debug

Build prove with pilconfig (only for debugging)

npm run buildall --pilconfig=testvectors/pilconfig.pil --starkstruct=debug

Build options

from: syntax is --from=<step> to indicate step where start build/rebuild

npm run buildsetup --from=c12setup

continue: this option hasn't additional argument. With this option buildall detected last step well done and continues from next step.

npm run buildsetup --continue

step: syntax is --step=<step> to indicate step to execute (one step only)

npm run buildsetup --step=c12setup

steps: to show list of steps

npm run buildsetup --steps

pil: syntax is --pil=<main.pil> where main.pil was name of pil to compile. For debugging could use basic_main.pil. See --starkstruct option

npm run buildsetup --pil=pil/basic_main.pil --starkstruct=debug

pilconfig: syntax is --pilconfig=<pilconfig.json> where pilconfig.json was name of config used in pil compilation. See --starkstruct option

npm run buildall --pilconfig=testvectors/pilconfig.json --starkstruct=debug

starkstruct: syntax is --startstruct=debug to generates automatic starkstruct adapted to pil bits number. Only for debugging. This option shall used with --pil or pilconfig if number of bits change.

npm run buildall --starkstruct=debug

build: with this option could change build directory, by default build directory is build/proof.

npm run buildall --build=build/basic_proof

input: with this option indicates input file to use.

npm run buildall --input=test/myinputfile.json

bctree: syntax is --bctree=<bctree_exec> specify an external binary (executable) to generate build constanttree

npm run buildall --bctree=../zkevm-prover/build/bctree
