Keep details of your Blockchain transactions private from other nodes using Zero-Knowledge Proof cryptography

Our Partners:


QED-it provides an enterprise solution for preserving privacy on the Blockchain

Using QED-it you can transfer ownership of Blockchain assets without revealing the confidential transaction details while still ensuring regulatory compliance according to custom-defined business rules.

QED-it enables running audit queries such as credit and risk scoring without revealing the underlying private data used to calculate the score.

QED-it uses standard compliant zero knowledge proof cryptography to ensure the confidentiality of transaction data and metadata delivering a scalable and robust enterprise solution.

How Zero-Knowledge Blockchain can help Europe tax GAFA?
The Zero-Knowledge Blockchain combines Blockchain’s greatest strength – decentralized sharing of information – to the Zero-Knowledge Proof properties for protecting confidential data.

QEDit shares proof, not data
Now that the provisions of the EU General Data Protection Regulation (GDPR) have become enforceable since 25 May, the work done by Israel-based startup QEDit to develop the ZeroKnowledge Blockchain has taken on a heightened relevance.
