op-program

op-program

Implements a fault proof program that runs through the rollup state-transition to verify an L2 output from L1 inputs. This verifiable output can then resolve a disputed output on L1.

The program is designed such that it can be run in a deterministic way such that two invocations with the same input data will result in not only the same output, but the same program execution trace. This allows it to be run in an on-chain VM as part of the dispute resolution process.

Compiling

To build op-program, from within the op-program directory run:

make op-program

This resulting executable will be in ./bin/op-program

Testing

To run op-program unit tests, from within the op-program directory run:

make test

Lint

To run the linter, from within the op-program directory run:

make lint

This requires having golangci-lint installed.

Running

From within the op-program directory, options can be reviewed with:

./bin/op-program --help
