Editor’s note: Below is the full text of the paper “Privacy-Protecting Regulatory Solutions Using Zero-Knowledge Proofs”. Download the PDF, or read the shorter summary blog post here. Of all the utility that programmable blockchains offer – security, predictability, interoperability, and autonomous economies, among others – as of today, the most widely used blockchains do not offer privacy. This remains a key impediment to their widespread adoption. Although not all crypto tokens are solely – or even principally – financial instruments, and can be used for a variety of purposes within the growing web3 ecosystem, blockchain users do transact with each other on blockchains using digital assets. The current architectures of most existing blockchains rely on transaction transparency to promote trust, but this default transparency and lack of privacy increases the risk of consumer harm by permitting other blockchain users to view the transaction history and holdings of any wallet holder.
