Immutable media on Cardano

A library that cannot burn

This site hosts nothing. Paste a pointer — your browser raises the bytes from the Cardano ledger, rebuilds them, and verifies every hash before a single word renders.

Unfindable by bots. Verifiable by anyone. Deletable by no one.

  • $handleopens that wallet’s latest library — no address to remember
  • library policy ida whole library — opens the latest registry head under it
  • txHash#ixa single scroll — rebuilds & verifies that file

Not a walled garden — anyone’s scrolls, channels, and registries resolve here.

    Off the conventional webA scroll has no ordinary content URL and must be reassembled from transactions. Search engines do not do that work; blockchain indexers can. This is not privacy.

On-chain Registry

Pulled live from the on-chain registry — nothing hardcoded.

Click a scroll to read it — your browser rebuilds it from the ledger and verifies its hash before a byte renders.

How this room works

The trust model is part of the interface — nothing here asks you to take its word for it.

Verify, don’t trust

Each scroll carries an on-chain SHA-256 commitment. This page recomputes it from the reconstructed bytes, locally, every time. A mismatch renders nothing. HTML scrolls open in a fully sandboxed frame: hash-verified is not the same as safe-to-execute, so scripts never run.

Three forms of stone

  • Lock — the whole file in one unspendable UTxO datum; in the live ledger state forever.
  • Chain — any size, as bare metadata transactions listed by a locked manifest. spec
  • Pages — the original CIP-25 page NFTs (the Bible, the Constitutions); read forever, superseded for writing.

Write your own

The protocol is open, tested, and implementable by strangers: the repository — minting tools, spec, conformance vectors. Start by minting a scroll — price your file, learn how it works, and mint it right from your browser — see which media types work, read the tutorial scroll above (it lives on-chain), or launch a publisher channel like BEACN Leaks — a byline nobody can forge.
