VerseLedger · x402

A granular attribution layer for poets. Instead of a one-time mint, VerseLedger meters the "Proof of Originality." Pay 0.01 USDC to cryptographically timestamp a stanza or signature, or 0.01 USDC to query the chain for a similarity check against the ledger. It turns the archive from a static list into a pay-per-verification utility for publishers and literary scouts.

The primitive.

full primer →

Access to the poetry archiving engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so writers — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveShift from 'storage' to 'verification service.' By pricing the timestamping and the plagiarism-check at the call level, the ledger becomes an active agent in the creative workflow rather than a passive database.

PlotLine · x402
A real-time collaborative logic engine for fiction where every narrative branch is a pay-per-vote micro-transaction. Authors publish 'Fractured Chapters' where the plot path is gated by liquidity; the story only progresses when the collective pool for a specific outcome hits its threshold. 0.01 USDC per vote ensures skin in the game while preventing bot-spamming of plot arcs. Readers don't just consume; they fund the creative direction one sentence at a time.
