We are using a simplified version of NIZKCTF this time. Our new platform is still secure and opensource, but does not need a GitHub account anymore.
Registration:
One account per team. If you want to receive job offers and invitations to sponsor's private bug bounty programs, mark the checkbox when registering your team.
Source:
You can find the source code for the Frontend here, and for the Backend here.
Open audit:
Flag submissions are completely transparent and subject to open audit. If you want to audit the scoreboard, take a look at the tool provided by nizkctf-admin-toolkit. During the competition, a signed and timestamped copy of the audit trail will also be recorded here, together with a scoreboard validated against it.
Cache:
Maybe you need to wait some seconds to see your score in the scoreboard.
