Embrace the Power of Enterprise Blockchains Without Exposing Private Data

QEDIT offers a cryptographically-secure privacy solution for enterprise blockchains that enhances trust and enables open collaboration among competitors and industry partners.

We leverage zero-knowledge proof cryptography to facilitate the transfer of digital assets on a shared ledger while ensuring that private transactional details (who sent what, and how much, to whom) are never exposed.

In addition to safeguarding sensitive business data, we keep companies compliant with local data privacy regulations through permissioned auditing tools for controlled transparency.
