SandStorm hackathon idea list

Idea list from SandStorm Hackathon

Choosing what to build on Blockchain & Solana is always a hard choice for Builders. Luckily, SandStorm Hackathon already offered a categorized list of what to build.
(Key learnings & top picks from the event can be found in this amazing post)
The original list is long and you can find it on the site, I will try to filter ones that can inspire Builders to plan their next move:
