Today we are proud to share two of our breakthrough transaction models that we’ve created to power Dusk Network.

TL;DR
As an industry-first to enable confidential spending of public outputs,
Phoenix will replace the old UTXO/RingCT transaction model within Dusk Network. Phoenix is unique because it guarantees transaction confidentiality even when users spend public outputs such as blind-bid rewards for staking or gas change (when too much is paid).

Zedger is the cornerstone of Dusk Network’s core technology for XSC. Zedger complements Phoenix by providing UTXO’s with account-based capabilities that enable the functionality required for Dusk Networks’ Confidential Security Contracts (XSC).
