Batch verification (2FA)

Batch verification requires each batch generated by main node to be signed-of by certain number of designated ENs before its committed on L1. To enable it configure as follows.

Main node / sequencer:

• batch_verification_server_enabled=true – enable
• batch_verification_threshold – required number of ENs to sign each batch
• batch_verification_accepted_signers – comma separated list of eth addresses corresponding to EN keys

Participating ENs:

• batch_verification_client_enabled=true – enable
• batch_verification_connect_address – ip and port of main node verification server (eg. 10.10.1.1:1234)
• batch_verification_signing_key – EN private key
