A new proposal suggests burning "spam" Bitcoin UTXOs. We explain why the "CAT" proposal is technically flawed, philosophically dangerous, and amounts to on-chain confiscation.
Today, we break down the controversial "CAT" proposal by Claire Ostrom. This idea suggests snapshotting and burning UTXOs associated with Ordinals and Stamps to curb spam. We analyze the technical flaws, the failed game theory, and why seizing user coins—even "dirty" ones—sets a dangerous precedent for Bitcoin censorship and on-chain confiscation.

Notes:
* CAT burns UTXOs under a specific threshold
* 100 million inscriptions are likely junk
