Quantus Weekly: Lattice Crypto Audit and Keystone Integration
Last week, the team addressed all issues raised in the audit of our lattice crypto library (rusty-crystals) and shipped networking updates to align with the latest Polkadot SDK. We also implemented Quantus address support on the open-source Keystone hardware wallet firmware and got our profile listed on the market intelligence platform “The Quantum Insider”.
Weekly Github activity report including 17 merged pull requests: https://github.com/Quantus-Network/n8n-workflows/blob/main/github/weekly-update-2025-12-01-11:59:59.md
Core Tech
- Resolved all findings in the audit of the core lattice cryptography library (qp-rusty-crystals).
- Completed ZK-Aggregation proof preparation (circuits, benchmarks, and QIP documentation) for the upcoming audit.
- Found optimizations in the plonky2 poseidon2 gate and zk-trie for increasing proving speed.
- Rolled back qp-header and updated sc-network to align with the latest Polkadot SDK standards.
Network & Infra
- Released the Desktop UI Miner for Windows, bug fixes for Linux and MacOS: https://github.com/Quantus-Network/quantus-apps/releases/latest
