### Regress
Regress is an offline block validation tool. It will not download block
information from anywhere like Persist tool. Regress will validate your
already persisted block in database. It will try to find any regression
introduced either by bugfixing or refactoring.
```bash
# usage:
./build/regress [--dataDir:your_db_path] --head:blockNumber
