Previously, whenever I heard about zero-knowledge proofs, I often thought this was a rather distant concept for practical users. But when I took a look at Dusk’s cryptography class, I started to see that ZK is not just a technical term—it can become a foundation for solving a very real problem in financial blockchain: how to prove that a transaction is valid without publicly disclosing all the information behind it.
Dusk uses many cryptographic primitives such as BLS12-381, JubJub, Schnorr, Poseidon, and Merkle trees." means that Dusk is using advanced cryptography to make financial blockchain transactions both verifiable and privacy-preserving.
In simple terms, zero-knowledge proofs (ZK proofs) let someone prove that they meet a requirement—such as passing KYC checks, having permission to buy an asset, or making a valid transaction—without exposing unnecessary personal or financial details on-chain.
The technologies mentioned are the underlying tools that make this possible:
BLS12-381 and JubJub: cryptographic curves used for efficient, secure proof and signature systems.
Schnorr: a digital-signature method that helps prove authorization.
Poseidon: a hash function designed to work efficiently inside ZK proofs.
Merkle trees: a way to verify that data belongs to a larger dataset without revealing every item in it.
The broader point is that Dusk’s PLONK-based ZK system aims to support “selective disclosure”: privacy when sensitive data should remain confidential, while still allowing verification or compliance checks when needed. This could be useful for regulated financial applications where participants must prove eligibility without publishing their full identity or transaction history.
