Zcash founder says claims of secret ZEC supply increase are false

Zooko Wilcox said users can independently verify the privacy coin’s circulating supply, while Boston Zcash said migration to Ironwood is not the right test for overissuance.

ZEC

Fact Check
The core claim — that Zcash founder Zooko Wilcox said claims of a secret ZEC supply increase are false and that users can independently verify the circulating supply — is directly confirmed by Wilcox's own X post (@zooko, 2026-07-29), where he states people who think ZEC's supply might be secretly inflated 'are wrong' and that anyone can verify locally today that the supply is 16,848,458 ZEC. This is corroborated by multiple news outlets (CryptoNews/BitcoinWorld, CoinNess). The secondary detail about Boston Zcash saying migration to Ironwood is not the right test for overissuance could not be independently verified via search, but the primary, headline claim is strongly supported by the founder's primary-source statement.
Summary

Zcash founder Zooko Wilcox rejected claims that ZEC’s supply may have been secretly increased, saying users can already verify the current total locally at 16,848,458 coins without waiting months. As Zcash moves from Orchard to Ironwood, Boston Zcash said a full migration of Orchard funds would not be the correct way to test for overissuance because the protocol’s carousel design means 100% of those funds will never move, including because some private keys have been lost. The comments push back on the idea that supply changes in the privacy-focused cryptocurrency could occur outside its public verification process.
