Write together. Sealed forever.

A Solana-powered collaborative writing platform where creators and their subscribers co-author content paragraph by paragraph, with every vote and winning contribution permanently sealed on-chain.

Built for the Solana Hackathon 2026 — Best Use of Solana track.

A creator starts a piece — a blog post, script, or story — and opens it to their inner circle. Subscribers submit the next paragraph. The community votes. The winner is locked on Solana forever, with the contributor's wallet address as permanent co-author. Repeat until the piece is complete.

Creator opens round
  → Smart contract issues contribution & vote tokens to eligible wallets
    → Inner Circle submits paragraphs (burns contribution token)
      → Voting opens (all eligible subscribers vote, burns vote token)
        → Winning paragraph sealed on Solana forever
          → Creator adds optional note → Next round

anchor test

• [vote, round, voter] — one vote per wallet per round, guaranteed by Solana. No off-chain enforcement.
• [submission, round, contributor] — one submission per contributor per round.
• [paragraph, piece, index] — sealed paragraphs addressable forever by piece + position.

Contribution and vote tokens are tracked on SubscriberRecord accounts. Issued by the creator at round open, burned on submit/vote. No monetary value. No transfer authority.

Full paragraph text lives on Arweave (permanent). Only the SHA-256 hash is written on-chain. Anyone can verify the text matches the hash.

1. Open the app. Connect a demo wallet (pre-funded devnet).
2. Navigate to "It Was the Night Before the Product Launch"
3. Vote on Round 4 — watch the live bar chart shift in real time
4. Creator closes the round → winning paragraph seals on Solana in ~400ms
5. Show the on-chain record: contributor wallet, timestamp, vote count — immutable and public

Pitch line: "That paragraph will exist on the Solana blockchain forever. The person who wrote it is now a published co-author."

No token economics. No staking. No financial transactions between users.

• NFT minting of the final piece
• Financial rewards to contributors
• Tradeable or monetary tokens
• On-chain storage of full paragraph text (hash only — keeps costs minimal)
