Why a bug that could have threatened XRP's 100 billion supply cap stayed hidden for years

A bug that could have let an attacker print new XRP (XRP) out of nothing sat in the XRP Ledger for more than a decade without anyone noticing because normal user activity never came close to triggering it, according to XRP Ledger Foundation . The 11-year-old bug mattered because it threatened the core rule XRP holders rely on: that the total supply can never exceed the 100 billion coins created at the blockchain’s debut in 2012. It was uncovered Sept. 22 by researcher Cayden Liao and Veria AI and reported internally.
