ZEC

Zcash is a privacy-focused cryptocurrency leveraging advanced cryptographic techniques (zk-SNARKs) to offer users the option of shielded transactions, ensuring the confidentiality of transaction details while maintaining the security and integrity of the blockchain.

Dusk Network and Zcash both use zero-knowledge proof cryptography to enable private transactions on a blockchain, but they are designed for fundamentally different markets.

Zcash

Zcash is a privacy-preserving cryptocurrency. Its primary goal is private value transfer — sending ZEC (its token) without revealing sender, receiver, or amount on the public ledger. Zcash pioneered the use of zk-SNARKs (specifically Groth16) in a live blockchain network starting in 2016. Users can choose between transparent transactions (visible on-chain, like Bitcoin) and shielded transactions (private via ZK proofs).

Zcash is a general-purpose currency, not a smart contract platform. Its privacy is deep and well-studied, but its programmability is limited compared to smart contract chains.

Dusk Network

Dusk Network is not primarily a privacy currency — it is a privacy-preserving smart contract platform aimed at regulated financial assets. Its ZK system (PLONK-based) enables not just private transfers but private smart contract execution: compliance rules, asset issuance logic, and trading conditions can be embedded in contracts without exposing sensitive business data on-chain.

Crucially, Dusk includes selective disclosure: issuers can configure which parties (auditors, regulators) can view transaction details when legally required. This makes it suitable for securities markets where total privacy would violate disclosure obligations, but total transparency would violate investor privacy.

The takeaway

Zcash is the mature, purpose-built choice for private cryptocurrency transactions. Dusk is the purpose-built choice for tokenizing regulated financial assets that require both privacy and auditable compliance. The two protocols occupy different niches despite sharing the ZK privacy category label.

Frequently Asked Questions

What is the difference between Dusk Network and Zcash?
Zcash is a privacy-focused cryptocurrency for private value transfer using Groth16 zk-SNARKs. Dusk Network is a privacy-preserving smart contract platform for regulated financial assets, using a PLONK-based ZK system that supports selective disclosure to auditors and regulators. Zcash is mature (launched 2016); Dusk launched its mainnet in 2024.
What is selective disclosure in Dusk Network?
Selective disclosure allows asset issuers on Dusk to configure which parties — such as auditors, regulators, or counterparties — can view the details of otherwise private transactions. This is critical for regulated securities that must be auditable by authorities while remaining private from the general public.
What ZK proof system does Zcash use?
Zcash uses Groth16 zk-SNARKs in its Sapling and later protocol upgrades. Groth16 is one of the most widely deployed ZK proof systems, known for small proof sizes and fast verification. Zcash pioneered the use of zk-SNARKs in a live blockchain network starting in 2016.
What ZK proof system does Dusk Network use?
Dusk uses a PLONK-based ZK proof system. PLONK is a universal and updatable SNARK that does not require a per-circuit trusted setup (unlike earlier systems), which simplifies the deployment of new private smart contracts without additional ceremony overhead.
Can Zcash be used for smart contracts?
Zcash has limited programmability compared to smart contract platforms. It is primarily designed as a privacy-preserving currency for value transfer, not for deploying arbitrary application logic. For privacy-preserving smart contracts, Dusk Network or other platforms are more suitable.
