Welcome to the VOID Storage Hack Challenge! Your mission is to decode the hidden messages embedded in the visuals. Submit the correct SHA256 hash to earn a spot in the final hackathon!
There are 3 different challenges: Easy, Pro, and Doom modes. If you successfully decode the messages in Pro or Doom mode, you’ll be invited to our main hacking event.
We want everyone to have a chance to participate and understand the methodology. We recommend starting with the easy one to get a feel for the VOID system.
The VOID algorithm is a system. We're here to prove its reliability. What you're interacting with is version 0.0.0.1 — an entry-level model. If you manage to break through this level, you'll gain access to a much more advanced experience like no other.
To prove the strength of our system, we're giving you insights and metadata that are usually hidden in most hack events. This is your chance to reverse-engineer with full transparency.
VOID is a unique storage technique developed by Devdeed. It’s currently implemented in our Web3-based messaging product NOCBY, where its advanced version secures all user data.
Thank you for joining the event, the event is done and we are still alive.

Hint: Intermediate level — solve this challenge to earn your entry ticket to the main hack event.
What you have:
@.).Sha 256 looks like: a004d-----------------------------------------------------------Tip: Inspect the image metadata and pay close attention to irregularities in the R channel.
Hint: Advanced level — combine three hidden visuals to find the solution.
Analyze all three together. Clues are distributed.
