Dash goes shielded with Zcash's Orchard

Twelve Years of Coin Mixing, Now Replaced

@Dashpay has activated Orchard-based shielded pools on its Evolution chain, marking what the project describes as the biggest privacy upgrade in its history. The new system hides the sender, receiver, and transaction amount on every transfer, with one-second confirmations and wallet sync completing in roughly 20 seconds.

The move ends more than a decade of reliance on PrivateSend, Dash's CoinJoin-based coin-mixing mechanism. Orchard marks a technical shift from the project's long-standing CoinJoin system, adding zero-knowledge cryptography originating from the Zcash ecosystem. Orchard replaces mixing-based privacy with modern zero-knowledge cryptography. It is Zcash's most advanced privacy system to date, removing the need for a trusted setup, modernizing shielded pools, and making private transactions far more practical across real-world use cases.

Dash CTO Samuel Westrich said the open source code integrated more smoothly than the team anticipated. In Zcash, transaction validity is proven using zero-knowledge proofs, which allow the network to verify transactions without revealing the sender, receiver, or transaction amount. That same guarantee now extends to Dash's Evolution chain.

What Comes Next for Dash

Dash announced the integration of the Orchard shielded pool into its Evolution chain, the second blockchain the project introduced in 2024, bringing expanded shielded transaction capabilities to standard transfers, with privacy-preserving token support planned shortly after launch. Shielded stablecoins and other assets are next on the roadmap.

Launched in 2014, Dash is one of the longest-running networks with built-in privacy at the protocol level. The Evolution chain expands Dash's architecture to support applications, tokens, and now zero-knowledge privacy primitives, without breaking compatibility with the broader network.

Despite the scale of the technical milestone, $DASH moved roughly 1% on the day of the announcement, suggesting markets had largely priced in the upgrade ahead of activation.
