Cardano: ZK Proofs Deliver Selective Disclosure on Preview

Cardano preview now hosts selective disclosure powered by ZK proofs, letting users prove age eligibility for beer purchases without revealing name, birth year or photo.

The demo executed two separate on-chain transactions through a Plutus V3 validator using Groth16 SNARK verification in Plutus V3 Aiken, recording only “age verified” while keeping all personal data off-chain and eliminating any need for L2s or sidechains.

Cardano on-chain ZK proof privacy implementations build directly on the network’s peer-reviewed proof-of-stake foundation established over the past year.

At $0.24 ADA sits precisely on its EMA50 support with the EMA200 at $0.25 capping upside, while neutral RSI at 49.75 and a MACD golden cross hint at latent bullish pressure inside tightening Bollinger bands between $0.23 and $0.24; any sustained push above upper-band resistance would likely stall until a retest of the 50-EMA floor confirms continuation.
