Warning

Upgrade and migration considerations:

1. To upgrade the platform, simply pull the latest image and restart, and the database migration will be performed automatically.
2. In general, downgrade operations are not supported. Upgrading versions with a large time span may result in data incompatibility, so please make sure to back up your data.
3. After the upgrade, there may be new configuration items and changes in file structure. It is recommended to consult the official documentation or the community.
4. If you are migrating to another branch project, please pay attention to whether the database structure has changed. The database after the change does not support rollback to the original version.
5. The community and the official maintainers are not responsible for data loss, data incompatibility, and other issues. For issues with branch projects, please contact the corresponding project maintainer.

• Create highly customizable challenges

  • Type of challenges: Static Attachment, Dynamic Attachment, Static Container, Dynamic Container

    • Static Attachment: Shared attachments, any configured flag can be accepted.
    • Dynamic Attachment: The number of flags and attachments must be at least the number of teams. Attachments and flags are distributed according to the teams.
    • Static Container: Shared container templates, no dynamic flag is issued, and any configured flag can be submitted.
    • Dynamic Container: Automatically generate and issue flags through container environment variables, and flag of each team is unique.

  • Dynamic Scores

    • Curve of scores:

      $$f(S, r, d, x) = \left \lfloor S \times \left[r + ( 1- r) \times \exp\left( \dfrac{1 - x}{d} \right) \right] \right \rfloor $$

      Where $S$ is the original score, $r$ is the minimum score ratio, $d$ is the difficulty coefficient, and $x$ is the number of submissions. The first three parameters can be customized to satisfy most of the dynamic score requirements.

    • Bonus for first three solves: The platform rewards 5%, 3%, and 1% of the current score for the first three solves respectively.

  • Disable or enable challenges during the competition, and release new challenges at any time.
