Nomos weekly report §

Milestone 1: Network Privacy and Mixnet §

Research §

• A Mixnet PoC was conducted to gauge end-to-end latency, revealing a slight latency increase when utilizing mixnet. Several potential optimization areas have been identified.

Development §

• Various enhancements for the Mixnet have been developed, including the addition of delays for Sphinx packets, auto port for integration tests, and introducing a graceful shutdown for mixnode elements.
• There’s an ongoing shift from channels to streams in mixnet message handling.
• Refactoring of Mixnet Node & Client: 320
• Mixnet PoC Architecture Documents: Mixnet-and-Network-Privacy-Architecture-613f53cf11a245098c50af6b191d31d2
• Mixnet Measurements Documentation: Mixnet-Measurements-551ade11ae4d44ca9f3d947ea6950c67
• Sphinx Packet Delay Support: 321
• Auto Port for Tests: 327
• Mixnet Criterion Measurement: 328
• Graceful Shutdown for Mixnet: 330

Milestone 2: Private PoS §

Research §

• Discussions were held about token-engineering and staking in private settings, resulting in documentation that delves into the validation and delegation aspects of PPoS. Current considerations involve the integration of the ZeroCash/zCash construction into the staking model.

Milestone 3: Data Availability Sampling (RS, KZG) §

Research §

• Limitations discovered during RS and KZG implementation, notably with RS library scalability issues and bls12_381 curve finite field challenges. Found KZG libraries are primarily designed for Ethereum, which constrains the blob size.
• Benchmarks for KZG implementation were carried out, and simulation runs were conducted for different configurations.
• Node decay in relation to data availability was analyzed, leading to the derivation of an equation for understanding node averages in the network.

Development §

• KZG Library: 325
• KZG Base Layer initial approach: 309
• Detailed KZG Operation Benchmarks: da-kzg-benches
• Node Decay Analysis & Results: gzqvbbmfnxyp
