This project provides the latest profile image link of the validator, and a scheduling task is performed every hour using Ubuntu cron. When the scheduling task runs, it compares the previous profile image link and if there are changes, it commits and pushes them to the public/identity.json file.

You can proceed with the build in the following order.

As the scheduling task runs, it commits and pushes to Git. To perform these tasks, you need Git login information, so you need to save authentication information.

$ git config credential.helper store

Once you enter your username and password, you won't need to enter it again.

# Edit crontab
$ crontab -e

# Clone repository
$ git clone https://github.com/FirmaChain/validator-identity-crawler.git
