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.
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.
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.
Maybe you need to wait some seconds to see your score in the scoreboard.
