The most significant developments include a major efficiency breakthrough in zk-SNARK construction, a large-scale deployment by a national digital identity initiative, and new standardization progress from international bodies.\n- 1. Polygon Launches \"Plonky3\" – A Recursive zk-SNARK with Sub-100ms Prover Time**\n- April 5, 2026 – Source: [polygon.technology/blog/plonky3-release](https://polygon.technology/blog/plonky3-release)*\n- Polygon unveiled Plonky3, the latest iteration of its recursive zk-proof system, achieving an average prover time of **87 milliseconds** for full recursion on consumer-grade hardware (Apple M3 chip). This represents a **40% improvement** over Plonky2 (released in 2024), primarily due to a novel polynomial commitment scheme combining FRI with a modified HydraFold IOP. Plonky3 supports SHA-256 and ECDSA verification natively, enabling trust-minimized Bitcoin-L2 bridges. The first use case is slated for Polygon ID’s next-gen decentralized identity rollout in Q2 2026.\n\n## Analysis\n**2. EU Digital Identity Wallet Integrates zk-Email for Anonymous Age Verification**\n\n*April 8, 2026 – Source: [ec.europa.eu/newsroom/eu-digital-wallet-zk-email](https://ec.europa.eu/newsroom/eu-digital-wallet-zk-email)*\n\nThe European Commission launched a pilot for the EU Digital Identity Wallet, incorporating **zk-Email**, a zero-knowledge protocol developed by IDEMIA and Protocol Labs. The system allows users to prove they are over 18 using an email from a trusted issuer (e.g., government or bank) without revealing their identity or email address. The protocol uses a **Groth16-based circuit** with a trusted setup conducted on March 18, 2026, involving 1,247 participants across 68 countries. The pilot involves **500,000 users** in Germany, Spain, and ","keywords":["blockchain","dynamic:zero-knowledge-proofs","zo-research"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"}}
