BitMemory

BitMemory is a decentralized blockchain archive that helps you save, own, and protect important documents, family trees, and historical records — forever. No one can censor or delete your story.

Inspiration

As a genealogist, I often saw families lose their stories, documents, and even entire histories due to wars, censorship, or simple neglect. Centralized archives are easily hacked, deleted, or rewritten — and history vanishes forever. I wanted to build something different: a permanent, open, and censorship-proof archive, where anyone could safely store and truly own their documents.

What I Learned

  • How to combine Web2 (Supabase) and Web3 (Algorand, Arweave/IPFS) for real-world user onboarding
  • How decentralized storage and blockchain can work together for both security and usability
  • The real-world complexity of identity, proof, and trust in archival systems

How I Built It

  • Frontend: React, TypeScript, Vite, Tailwind CSS
  • Backend & DB: Supabase (PostgreSQL, Edge Functions for serverless logic)
  • Blockchain: Algorand (using TEAL+, Python, algosdk, AtomicTransactionComposer)
  • Storage: IPFS for decentralized file storage
  • AI Tools: mostly Bolt.new, Roo AI, Recraft AI

Challenges

  • Extreme Deadline: The biggest challenge was time. I discovered the hackathon only three days before the submission deadline, so everything — from idea to code to demo — had to be done at top speed. There was no time for overthinking, just building and shipping.
  • Bolt.new Rollercoaster: Bolt.new was an amazing accelerator at the start, letting me bootstrap the whole project lightning-fast. But as the deadline came closer, I spent the last 24 hours fighting endless bugs, edge cases, and mysterious errors. I learned a lot about both my patience and my debugging skills.
