# Nomos Monthly Report - August 2023
|
||
|
|
|
||
|
|
## Network Privacy and Mixnet
|
||
|
|
|
||
|
|
### Research
|
||
|
|
- Conducted in-depth research on Nym mixnet architecture to design prototype architecture.
|
||
|
|
- Discussed mixnet topology management and reached a preliminary agreement on architecture.
|
||
|
|
- Analyzed end-to-end latency in Mixnet PoC, identifying potential optimization areas.
|
||
|
|
|
||
|
|
### Development
|
||
|
|
- Implemented a prototype for Sphinx packet building, mixing packets at the first hop of gossipsub with 3 mixnodes.
|
||
|
|
- Added support for libp2p in tests and nomos node.
|
||
|
|
- Developed base implementation of Mixnet PoC and continued improvements.
|
||
|
|
- Implemented mixnode core module and mixnet-client library.
|
||
|
|
- Added features like Sphinx packet delay support, auto port for integration tests, and graceful shutdown for mixnode elements.
|
||
|
|
- Began shifting from channels to streams in mixnet message handling.
|
||
|
|
|
||
|
|
### Documentation
|
||
|
|
- Created Mixnet Architecture document: [Mixnet Architecture](https://www.notion.so/Mixnet-Architecture-613f53cf11a245098c50af6b191d31d2)
|
||
|
|
- Prepared Mixnet Measurements documentation: [Mixnet Measurements](https://www.notion.so/Mixnet-Measurements-551ade11ae4d44ca9f3d947ea6950c67)
|
||
|
|
|
||
|
|
## Private Proof of Stake (PPoS)
|
||
|
|
|
||
|
|
### Research
|
||
|
|
- Worked on PPoS design, addressing potential metadata leakage due to staking and rewarding.
|
||
|
|
- Focused on potential bribery attacks and privacy reasoning.
|
||
|
|
- Updated draft addressing comments related to shielded and transparent transaction types.
|
||
|
|
- Defined an opportunistic voting problem.
|
||
|
|
- Continued analysis on zCash transaction's construction.
|
||
|
|
- Discussed token-engineering and staking in private settings.
|
||
|
|
|
||
|
|
### Development
|
||
|
|
- Progress on this project was slower compared to others and requires more attention going forward.
|
||
|
|
|
||
|
|
## Data Availability Sampling (DAS)
|
||
|
|
|
||
|
|
### Research
|
||
|
|
- Analyzed data decimation in the data availability problem.
|
||
|
|
- Conducted DA benchmarks and analysis for data commitments and encoding.
|
||
|
|
- Explored and discarded the idea of node sharding.
|
||
|
|
- Studied RS+KZG in the context of DA architecture.
|
||
|
|
- Analyzed node decay in relation to data availability.
|
||
|
|
- Discovered limitations in RS and KZG implementation, particularly with library scalability and finite field challenges.
|
||
|
|
|
||
|
|
### Development
|
||
|
|
- Created basic wrappers and APIs for Reed-Solomon encoding and KZG commitments.
|
||
|
|
- Implemented RS and KZG libraries with simplistic APIs.
|
||
|
|
- Conducted benchmarks for KZG implementation and simulation runs for different configurations.
|
||
|
|
- Developed KZG Base Layer initial approach.
|
||
|
|
|
||
|
|
### Documentation
|
||
|
|
- Improved upper bound analysis on data availability probability: [Overleaf Document](https://www.overleaf.com/read/gzqvbbmfnxyp)
|
||
|
|
- Documented RS & KZG benchmarking results: [Notion Document](https://www.notion.so/2D-Reed-Solomon-Encoding-KZG-Commitments-benchmarking-b8340382ecc741c4a16b8a0c4a114450)
|
||
|
|
|
||
|
|
## Testing, CI, and Simulation App
|
||
|
|
|
||
|
|
### Development
|
||
|
|
- Made various fixes and improvements to the simulation application.
|
||
|
|
- Shared simulation app and instructions.
|
||
|
|
- Updated and merged CI improvements.
|
||
|
|
- Implemented parallel node init for improved simulation run times.
|
||
|
|
- Developed branch overlay for simulating 100K+ nodes.
|
||
|
|
- Updated sequential builds for nomos node features in CI.
|
||
|
|
- Created a new repository for simulations configurations and test results.
|
||
|
|
- Implemented graceful shutdown of simulations.
|
||
|
|
- Added support for CSV format output of simulation data.
|
||
|
|
|
||
|
|
## Challenges and Next Steps
|
||
|
|
|
||
|
|
1. The Private PoS project is progressing slower than others and requires more attention.
|
||
|
|
2. Addressing limitations discovered in RS and KZG implementations, particularly scalability issues.
|
||
|
|
3. Continuing to optimize the Mixnet implementation based on PoC results.
|
||
|
|
4. Further development and refinement of the simulation app for more comprehensive testing.
