Why this matters. With transparent money like Bitcoin, anyone can check that no coins were forged by reading the public ledger. Shielded money hides the amounts, so you cannot just look. Instead the cryptography itself has to guarantee that no one can create money in secret. Ironwood matters because a bug was found in that guarantee for the Orchard pool. The upgrade closes the gap and gives anyone a way to confirm that the total supply of ZEC is still honest.

Ihe Mere Osisi Ironwood Ji Dị Mkpa
Na ngwụcha ọnwa Mee 2026, onye nyocha nchekwa onwe ya Taylor Hornby, n'oge nyochaa usoro maka Ụlọ nyocha echekwara, responsibly disclosed a soundness bug in the Orchard shielded pool. Orchard was Zcash's newest shielded pool at the time, and the flaw sat in an elliptic-curve part of its zero-knowledge circuit, which uses the Halo 2 na-egosi usoro.
- Ihe na-egosi na azụmahịa bụ nke ziri ezi abụghị ihe ga-eme ka o doo anya.
- Na usoro iwu, onye na-awakpo nwere ike iji ntụpọ ahụ mepụta uru adịghị mma n'ime ọdọ mmiri Orchard ma jiri ego ndị na - abụghị nke ha mee ihe, hapụ enweghị akara ọ bụla node nkịtị ga - ejide.
- Zcash's turnstile ka na-emebi ego ole uru nwere ike ịhapụ Orchard, yabụ enweghị ike ịgbagha ngụkọta ahụ, mana cryptography nke ọdọ mmiri anaghịzi ekwe nkwa na mkpụrụ ego ọ bụla zoro ezo n'ime ya bụ ezigbo.
The numbers above are a simplified picture. The real flaw was in a specific piece of the circuit's math, not a literal count of coins going in and out. The point to take away is only that a soundness bug can let value be created inside the pool without detection.
Importantly, there is no evidence the bug was ever exploited, no evidence of impact to user funds, and no evidence that the total supply of ZEC changed. It was found through security research and fixed before any known harm.

Turnstiles are not new to Zcash. The network has used them before, at the boundaries between the Sprout, Sapling, and Orchard pools, so that value moving between pools stays auditable and no pool can release more than legitimately entered it.
Iwu nkwekọrịta na-eme ka ego ọ bụla bara uru, gụnyere Ironwood, n'ime oke ego kachasị nke netwọkụ ahụ. Ya mere nguzozi ọdọ mmiri enweghị ike ịbaghị uru.

Wallets and node software handle most of this automatically, but the practical shift is simple: over time, move shielded holdings from the old Orchard pool through the turnstile into the Ironwood pool. Follow the guidance from your wallet provider, and always update to a supported release before the activation block.

Do I need to do anything? Keep your wallet and node software updated to a supported release before the activation block. Your wallet moves funds into Ironwood over time as you spend, so there is nothing manual to rush. Follow your wallet provider's guidance.
Is Zcash still private? Yes. Ironwood keeps the same shielded privacy that hides sender, receiver, and amount. This upgrade is about supply integrity, not privacy.
