About this artifact

AI-generated (deepfake) MP4 impersonating Bitcoin Core developer Gloria Zhao to criticize OP_RETURN relay policy; inscribed via OP_RETURN (Oct 2025, taking up most of the block). safety:withheld - the entry and a verified reconstruction recipe are kept (reconstruct it locally with the command), but the video itself is deliberately NOT hosted on the site, as a precaution against republishing the impersonation.

How it was stored

OP_RETURN explicitly marks an output as unspendable and lets it carry a small data payload. Unlike fake-address methods, it does not create a spendable-looking UTXO. That makes it the least deceptive standard way to place small data on-chain.
