A photograph associated with Gulagu.net and Vladimir Osechkin, uploaded alongside the organisation's logo in 2021. Both were stored using P2SH outputs, a technique that hides data in what looks like an ordinary script hash.
P2SH methods are two-stage. First, a setup transaction creates script-hash outputs. Later, a spend transaction reveals input scripts containing the actual data plus a redeem script. Because the data appears when the output is spent, it does not remain in the UTXO set.
