The Platform
Void Hub focuses on the pieces a competitive room needs: friends, problem preparation, source accounts, submissions, results, and profile history.
Start a match from your friends list, accept or reject invitations, prepare the arena, and keep the room focused on solving.
Ranked matches update Elo, wins, losses, solved count, active days, and the result screen after the room ends.
Profiles show rating, recent submissions, country flag, bio, birthday when visible, match stats, and privacy choices.
Rooms cache time limits, memory limits, examples, notes, tags, and statement formatting before players enter the arena.
Online friends appear first, invitations can show match details, and the invite list includes head-to-head context.
Flow
Use email, Google, or GitHub, then complete the username step for new social accounts.
Connect Codeforces or HackerRank from settings so rooms can prepare languages and later submit through the right account.
Choose BO3, BO5, Blitz, or Pick & Play, then send a detailed invitation from your friends list.
The room tracks submissions, verdicts, penalties, exits, and rating changes when the match ends.
Problem Library
The room checks cached metadata first, then fetches missing statement details so the arena opens with the needed data already in place.
Statement files currently available for duel preparation across the local problem sources.
Room setup supports the match styles already built into the compete page.
Settings include source account links used by rooms and compiler preparation.
Recent activity, match record, bio, avatar, country flag, and visibility controls.
Match endings account for solved count, penalty minutes, and leaving the room.
Global Rankings
Rankings come from stored user ratings. Empty accounts start from the default rating until ranked rooms produce results.
