About this artifact

The logo of Gulagu.net, the Russian anti-torture organisation founded by Vladimir Osechkin, stored in 2021. The group publishes evidence of abuse in Russian prisons, and its material is routinely blocked inside Russia — which is the point of putting it somewhere no government can reach.

How it was stored

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.
