Below are notable cryptographic primitives and protocols introduced or gaining prominence up to this date.\n- Type**: Post-quantum digital signature scheme\n- Basis**: Isogeny-based cryptography on supersingular elliptic curves\n- Improvements**: An optimized variant of the original SQIsign, reducing signature size to ~200–300 bytes and improving signing speed by over 50% through new path-finding algorithms in the isogeny graph.\n\n## Analysis\n- **Status**: Submitted to NIST’s post-quantum standardization process (Round 4).\n\n- **Source**: https://squisign.org/sqisign-plus-whitepaper-2025.pdf\n\n- **Type**: Recursively composable zero-knowledge proof system\n\n## Sources\n- https://squisign.org/sqisign-plus-whitepaper-2025.pdf\n- https://zcash.github.io/halo-infinite\n- https://zkbridge.org/whitepaper-v3.pdf\n- https://eprint.iacr.org/2025/301\n- https://developers.cloudflare.com/pir-http\n- https://www.w3.org/TR/did-core-2026/\n- https://csrc.nist.gov/projects/post-quantum-cryptography\n- https://zkproof.org\n- https://eprint.iacr.org/\n\n## Implications\n- Security findings related to vulnerability warrant review by infrastructure teams\n- Cost dynamics around Private Information Retrieval could influence enterprise adoption timelines\n- Scaling considerations for Deployment may differ from controlled-environment results","keywords":["mathematics-cs-theory","zo-research","blockchain","quantum-computing"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"}}
