Nomos 31st July

[Network implementation and Mixnet]:

Research

• Initial analysis on the mixnet Proof of Concept (PoC) was performed, assessing components like Sphinx for packets and delay-forwarder.
• Considered the use of a new NetworkInterface in the simulation to mimic the mixnet, but currently, no significant benefits from doing so have been identified. Development
• Fixes were made on the Overlay interface.
• Near completion of the libp2p integration with all tests passing so far, a PR is expected to be opened soon.
• Link to libp2p PRs: https://github.com/logos-co/nomos-node/pull/278, https://github.com/logos-co/nomos-node/pull/279, https://github.com/logos-co/nomos-node/pull/280, https://github.com/logos-co/nomos-node/pull/281
• Started working on the foundation of the libp2p-mixnet transport.

[Private PoS]:

Research

• Discussions were held on the Privacy PoS (PPoS) proposal, aligning a general direction of team members.
• Reviews on the PPoS proposal were done.
• A proposal to merge the PPoS proposal with the efficient one was made, in order to have both privacy and efficiency.
• Discussions on merging Efficient PoS (EPoS) with PPoS are in progress.

[Carnot]:

Research

• Analyzing Bribery attack scenarios, which seem to make Carnot more vulnerable than expected.

Development

• Improved simulation application to meet test scale requirements (https://github.com/logos-co/nomos-node/pull/274).
• Created a strategy to solve the large message sending issue in the simulation application.

[Data Availability Sampling (or VID)]:

Research

• Conducted an analysis of stored data "degradation" problem for data availability, modeling fractions of nodes which leave the system at regular time intervals
• Continued literature reading on Verifiable Information Dispersal (VID) for DA problem, as well as encoding/commitment schemes.
