Explains concrete inflation vectors: an implementation bug in linking tags allows revealing multiple key image values and would permit an eightfold spend (patched before exploitation), a flawed MPC trusted setup transcript for Zcash’s Sprout could let an observer create arbitrary hidden value (unknown if exploited), and a historic Bitcoin integer‑overflow transaction did create inflation and forced a rollback. Shows commitment algebra and range‑proof failures, why counting coinbase or requiring transparent migration is insufficient, and how a future adversary finding a discrete‑log relationship yields undetectable inflation.
