<ul>
<li>Improved the mixnet implementation based on latest discussion. <ahref="https://github.com/logos-co/nomos-node/pull/307"class="external">307</a></li>
<li>Base implementation of Mixnet PoC: <ahref="https://github.com/logos-co/nomos-node/pull/302"class="external">302</a></li>
<li>Refactor to encapsulate message body creation&write&read: <ahref="https://github.com/logos-co/nomos-node/pull/308"class="external">308</a></li>
<li>New issues related to mixnet: <ahref="https://github.com/logos-co/nomos-node/issues?q=is%3Aopen+is%3Aissue+label%3Amixnet"class="external">issues?q=is%3Aopen+is%3Aissue+label%3Amixnet</a></li>
<li>Updated draft addressing comments related to shielded and transparent transaction types.</li>
<li>Defined an opportunistic voting problem.</li>
<li>Continuing analysis on zCash transaction’s construction.</li>
<li>This is currently the project that is going slowest and needs more attention going forward. It’s also the most complex and with the most unknowns.</li>
<li>Created a new repository for simulations configurations and test results: <ahref="https://github.com/logos-co/nomos-simulations"class="external">nomos-simulations</a></li>
<li>Updates and discussed test runs: <ahref="https://github.com/logos-co/nomos-simulations/pull/3"class="external">3</a></li>
<li>Changes to support CSV format output of simulation data: <ahref="https://github.com/logos-co/nomos-node/pull/304"class="external">304</a> and <ahref="https://github.com/logos-co/nomos-node/pull/306"class="external">306</a></li>
<li>Minor issue on integration tests fixed: <ahref="https://github.com/logos-co/nomos-node/pull/315"class="external">315</a></li>
<li>Studied RS+KZG in context of our DA architecture.</li>
<li>RS: basic encoding/decoding lib. Created a basic wrapper around reed-solomon-encoding library to work with arbitrary bytearrays with the simples API possible. Created basic tests and docs as well.</li>
<li>KZG: basic commitment + proof creation, also proof verification lib. Same here, created a simplistic API that abstract from the confusing types in the underlaying used library.</li>
<li>Created a simplistic API for RS: <ahref="https://github.com/logos-co/nomos-node/pull/303"class="external">303</a></li>
<li>Created a simplistic API for KZG: <ahref="https://github.com/logos-co/nomos-node/pull/309"class="external">309</a></li>
