Written to the chain on 29 Apr 2016, block 409,471.
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.
AtomSea and EMBII built a higher-level publishing system on top of fake-key-hash style storage. A top-level transaction acts like an index: it contains ordered transaction IDs, length markers, filenames, captions, and sometimes profile or signature metadata.
