Dash Launches ZK-Privacy Based on Zcash
Dash has launched ZK-based privacy features built on Zcash's Orchard protocol. This is now integrated directly into the Dash Platform's consensus (v4.0.0), providing a native, non-custodial privacy model alongside the existing CoinJoin system. It offers optional confidentiality, hiding sender, receiver, amount, and balance within a shielded pool.
The implementation adapts Zcash's Orchard protocol (using Halo 2 without a trusted setup) to Dash Platform, handling state transitions, GroveDB storage, fees, and wallet sync. A critical double-spend vulnerability discovered in Orchard prior to release was patched using updated libraries, with Dash adding a SumTree structure for extra security.
Users can privately transfer Platform Credits (pegged 1:100 billion to DASH) and move funds to/from the main Dash Core chain. Wallet synchronization, which is required to detect incoming private transactions, took about 21 seconds in testing, noted as significantly faster than a comparable Zcash wallet.
Future plans include extending shielded pools to native Platform tokens and NFTs, aiming to combine ZK-privacy with token issuance and direct exchangeability with Dash. Mobile wallet support for the new feature is expected soon.
