atomsea-embii ✓ verified on-chain
OuterSpace.mp3 (~4 MB, off-Bitcoin payload)
Media for this artifact is not hosted on the site — The AtomSea toplevel/index and some metadata txs are on Bitcoin mainnet (block 409471), but the file-payload transactions the index links to are NOT on Bitcoin (verified: e.g. data tx 8b0c671f...746f30 returns confirmed:false / 404). Apertus 0.3.5-beta supported multi-chain storage and the bulk payload lives on Datacoin, so the MP3 cannot be reconstructed from a Bitcoin backend.
EMBII's largest known inscription (his own claim, twitter.com/EMBII4U/status/1655969645927563266). The '4 MB' is from EMBII's inscription label, not measured on Bitcoin: the index is on Bitcoin but the payload is cross-chain (Datacoin), so size can't be confirmed from the Bitcoin chain. Genuine AtomSea/Apertus object; category atomsea-embii is correct.
