SPV bloom filters were designed to obscure your addresses from nodes, the intersection attack math shows why they don't, and what actually works instead.
№ 077BitcoinBitcoin Script Has No Loops: Security by Design
Bitcoin Script omits loops entirely, not as a limitation, but as a deliberate defense against Denial-of-Service attacks on every node in the network.
