Dash activates Orchard privacy system, adopting Zcash tech after security scare

Dash, a digital payments-focused cryptocurrency launched in 2014, has rolled out a new privacy system called Orchard designed to strengthen user anonymity and transaction confidentiality. The system leverages Zcash’s zero-knowledge proof technology, enabling users to send Dash while shielding the sender, recipient, and amount from public view.

Mainnet launch and transaction improvements

The Dash Core team announced on X that Orchard pools were activated immediately, emphasizing faster confirmation speeds. According to the developers, transactions on Orchard can be confirmed in approximately one second, while wallet synchronization now takes roughly 20 seconds.

Previously, Dash depended on its PrivateSend feature, which mixed user coins through CoinJoin to obscure transaction trails. PrivateSend provided a degree of fungibility, but required pooling multiple user transactions to make tracing more difficult.

With Orchard, Dash transitions to a cryptographically advanced approach. The system implements zero-knowledge proofs, allowing the network to confirm transaction validity without revealing any participant details or transaction amounts. This represents a significant privacy upgrade compared to the older, mixing-based model.

Dash’s mainnet activation marks the beginning of a new era for privacy on its network, with the team reporting that users can now send funds with the details fully hidden from the public ledger.

Samuel Westrich, chief technology officer of Dash Core Group, described Orchard’s open-source code as mature and relatively straightforward to integrate. The upgrade has been deployed on Dash Evolution, the project’s updated chain introduced in 2024 to deliver faster transaction times and support for token-based applications.

Currently, Orchard covers standard Dash transfers. The team has announced plans to extend privacy features to stablecoins and other digital assets in the future.

Mini dictionary: Zero-knowledge proof — A cryptographic method allowing one party to prove to another that a statement is true without revealing any information beyond the validity of the statement itself. This is often used in privacy coins to keep sensitive transaction data confidential.

Zcash bug and market response

Orchard’s implementation on Dash arrives at a turbulent time for Zcash, the privacy-focused cryptocurrency that originally developed the Orchard system. On May 29, 2026, security researcher Taylor Hornby discovered a flaw in Zcash’s Orchard circuit. The bug had existed since Orchard’s activation in May 2022, raising concerns about Zcash’s total supply integrity.

This vulnerability could have allowed the creation of counterfeit Zcash tokens in complete secrecy due to Orchard’s privacy features. Following disclosure on June 4, Zcash (ZEC) experienced a steep price decline, falling from about $602 to around $299, marking a drop of more than 50%.

Zcash developers rapidly addressed the bug through an emergency update and have stated they found no evidence of the flaw being exploited.

The upcoming Ironwood update, scheduled for July 28 at block height 3,428,143, introduces a “turnstile” accounting system to cap total supply and enable verification in case counterfeit coins were created.

Dash’s new privacy system uses Orchard technology but operates independently from Zcash’s network. Despite technical similarities, no part of the bug discovered in Zcash affects Dash directly. However, the timing of Dash’s adoption of Orchard comes only weeks after Zcash’s critical incident.

The Dash market showed little reaction to the Orchard integration. On the day of the announcement, Dash edged up by just 0.2%, maintaining a market capitalization near $431 million and ranking 84th among cryptocurrencies by market value.
