<ul>
|
||
<li>Milestone 1: Understanding Data Availability (DA) Problem</li>
|
||
<li>High-level exploration and discussion on data availability problems in a collaborative offsite meeting in Paris.</li>
|
||
<li>Explored the necessity and key challenges associated with DA.</li>
|
||
<li>In-depth study of Verifiable Information Dispersal (VID) as it relates to data availability.</li>
|
||
<li><strong>Blocker:</strong> The experimental tests for our specific EC scheme are pending, which is blocking progress to make final decision on KZG + commitments for our architecture.</li>
|
||
<li>Milestone 2: Privacy for Proof of Stake (PoS)</li>
|
||
<li>Analyzed the capabilities and limitations of mixnets, specifically within the context of timing attacks in private PoS.</li>
|
||
<li>Invested time in understanding timing attacks and how Nym mixnet caters to these challenges.</li>
|
||
<li>Reviewed the Crypsinous paper to understand its privacy vulnerabilities, notably the issue with probabilistic leader election and the vulnerability of anonymous broadcast channels to timing attacks.</li>
|
||
</ul>
|
||
<p><strong>Development</strong></p>
|
||
<ul>
|
||
<li>Milestone 1: Mixnet and Networking</li>
|
||
<li>Initiated integration of libp2p to be used as the full node’s backend, planning to complete in the next phase.</li>
|
||
<li>Begun planning for the next steps for mixnet integration, with a focus on understanding the components of the Nym mixnet, its problem-solving mechanisms, and the potential for integrating some of its components into our codebase.</li>
|
||
<li>Milestone 2: Simulation Application</li>
|
||
<li>Completed pseudocode for Carnot Simulator, created a test pseudocode, and provided a detailed description of the simulation. The relevant resources can be found at the following links:
|
||
<ul>
|
||
<li>Carnot Simulator pseudocode (<a href="https://github.com/logos-co/nomos-specs/blob/Carnot-Simulation/carnot/carnot_simulation_psuedocode.py" class="external">carnot_simulation_psuedocode.py</a>)</li>
|
||
<li>Test pseudocode (<a href="https://github.com/logos-co/nomos-specs/blob/Carnot-Simulation/carnot/test_carnot_simulation.py" class="external">test_carnot_simulation.py</a>)</li>
|
||
<li>Description of the simulation (<a href="https://www.notion.so/Carnot-Simulation-c025dbab6b374c139004aae45831cf78" class="external">Carnot-Simulation-c025dbab6b374c139004aae45831cf78</a>)</li>
|
||
</ul>
|
||
</li>
|
||
<li>Implemented simulation network fixes and warding improvements, and increased the run duration of integration tests. The corresponding pull requests can be accessed here:

||
<li>Simulation network fix (<a href="https://github.com/logos-co/nomos-node/pull/262" class="external">262</a>)</li>
|
||
<li>Vote tally fix (<a href="https://github.com/logos-co/nomos-node/pull/268" class="external">268</a>)</li>
|
||
<li>Increased run duration of integration tests (<a href="https://github.com/logos-co/nomos-node/pull/263" class="external">263</a>)</li>
