Quantus Weekly: Threshold Dilithium Signatures and Distributed Coordination
Power and authority split between multiple parties. Distributed coordination.
But post quantum signatures are 20x - 80x larger than Bitcoin signatures. A traditional multisig solution has its place but adds overhead which is unacceptable for certain use cases.
This week we shipped threshold dilithium signatures. This enables a distributed group to sign transactions and generate a single signature on-chain. Basically, sharding a private key.
That’s necessary for custodians, cross-network applications, and secure automated usage of the chain.

Core Tech & ZK
- Implemented threshold signatures, enabling secure distributed signing.
- Reduced ZK circuit overhead.
- Added proof aggregation support to the wormhole example binary, ongoing integration into the chain and CLI.
- Upgraded our ZK circuits and Poseidon hashing algorithm to universally handle all data types (generic storage hashing), now integrated into the chain and CLI.
- Added support for proof aggregation over asset IDs within the ZK circuits.
- Optimized the CLI for faster transaction processing and added high-security recovery scripts.
Web & Mobile App Updates
- Released a new version of the UI Mining App with granular sliders for CPU and GPU usage, alongside fixes for hashrate reporting.
- Finalized and merged full hardware wallet support into the mobile app.
- Added support for managing multiple accounts within a single mobile wallet instance.
- Implemented high-security screens and began development on “Guardian” recovery flows.
- Refined the “send” screen UX, improved error handling, fixed authentication timer bugs, and unified app icons.
- Configured daily database backups, fixed system services, and cleaned up the Task Master code (wallet app event tracking).
