Zero Knowledge (ZK) coins: are they halal?

What is Zero Knowledge (ZK)?

Zero Knowledge coins power cryptographic scaling or privacy infrastructure that lets transactions be verified without revealing their underlying data.

How CryptoUmmah screens Zero Knowledge (ZK) coins

ZK is generally one of our cleanest categories, since it's fundamentally a cryptographic infrastructure layer rather than a financial product — riba and maysir concerns are essentially absent by design. Where scores vary, it's a gharar factor tied to how audited and mathematically vetted the underlying zero-knowledge proof system is, since a flaw in unaudited cryptographic infrastructure represents a different but real form of structural uncertainty. Across the 66 Zero Knowledge (ZK) coins we've screened, the average Shariah compliance score sits at 63.8/100, with 29% classified Halal, 59% Mashbooh, and 12% Haram.
