Challenger

The challenger monitors the L2 operator's activities, issuing challenges against any misconduct, such as invalid block submissions and output proposals.

Step 1: Set Challenger Mnemonic on .env.challenger

The challenger bot should be independent from executor and output submitter. It will monitor the output oracle and delete invalid output proposals.

• TYPEORM_DATABASE should be the name of the database previously created

• L2_CHAIN_ID your minitia's chain ID and bridge executor menmonic found in $HOME/.minitia/artifacts/config.json

• BRIDGE_ID can be found in $HOME/.minitia/artifacts/artifacts.json

• CHALLENGER_MNEMONIC can be found in $HOME/.minitia/artifacts/config.json's challenger field
