Bitcoin developer hides a 66KB image in a transaction to expose a governance blind spot vulnerable to spam

Bitcoin developer Martin Habovštiak embedded a 66KB image in a single transaction without using OP_RETURN or Taproot, bypassing popular spam filters while following consensus rules. This demonstration exposed a governance vulnerability showing that closing one data pathway doesn't eliminate the capability but merely redirects it elsewhere.

• →A Bitcoin developer successfully embedded a 66KB image in a transaction without using traditional methods like OP_RETURN or Taproot.
• →The transaction followed all Bitcoin consensus rules and can be verified using standard node software.
• →The demonstration exposed that existing spam filters can be bypassed through alternative methods.
• →This reveals a governance blind spot where closing one data pathway doesn't eliminate data embedding capabilities.
• →The experiment was conducted to highlight protocol vulnerabilities rather than create art or generate profit.
