BitcoinZ Supply Integrity

An independent security review of BTCZ - June 2026

  • No inflation, counterfeiting, or double-spend bug in the shielded (private) transaction system, or anywhere else examined.

  • BitcoinZ verifies private transactions against the original, integrity-checked Zcash cryptographic parameters — so the class of deep bug behind both the 2018 and 2026 incidents cannot have been introduced in BitcoinZ.

  • The 2018 counterfeiting fix is in place, and a live supply “turnstile” actively rejects any block that would imply impossible — that is, counterfeit — balances.
