Zcash Ironwood Upgrade Finalizes to Patch Orchard Pool Flaw
The fix lands after a counterfeiting bug briefly pushed ZEC to a $252 intraday low — and the recovery since tells you the market read the patch as credible.
Zcash is a privacy-oriented cryptocurrency that operates on its own blockchain as a standalone Layer 1 network. It is widely recognized as the first protocol to implement zero-knowledge proofs for private peer-to-peer payments, allowing transactions to be validated without disclosing wallet balances, transferred amounts, or the identities of the participants. This approach addresses the transparency limitations found in most cryptocurrencies, where transaction details are recorded on a public ledger. The network supports both transparent public transactions and shielded private transactions through Unified Addresses, giving users flexibility over the level of confidentiality they require. Zcash currently relies on a Proof-of-Work consensus mechanism, with plans to transition toward Proof-of-Stake through a future upgrade. Its shielded pool leverages Halo, an advanced zero-knowledge proving system, to enable trustless verification of encrypted transfers. The protocol features a fixed supply cap of 21 million ZEC and a halving schedule modeled on Bitcoin's issuance design. Originating from a 2013 proposal by cryptographers known as Zerocoin, the project evolved into an independent blockchain maintained by a self-funded development ecosystem supported by community grants and coinholder-directed funding.
