<li>We have updated the Cryptarchia specification with the update epoch stabilization schedule - <ahref="https://github.com/logos-co/nomos-specs/pull/79"class="external">PR</a>.</li>
<li>Analysis of adversarial inference of relative stake: derived an equation that can be used to infer the Lagrange parameter in the maximum likelihood inference of relative stake - the details of the <ahref="https://www.overleaf.com/project/656dfacf4929b4a3d6d2ffe5"class="external">analysis</a>.</li>
<li>Removed assumptions on Carnot being the consensus algorithm in the mempool: <ahref="https://github.com/logos-co/nomos-node/pull/605"class="external">PR</a>.</li>
<li>Separate ledger and consensus to prepare for integration: <ahref="https://github.com/logos-co/nomos-node/pull/606"class="external">PR</a>.</li>
<li>Work in Progress (WIP): The <ahref="https://www.notion.so/Mixnet-Incentivization-6db9731a221b49878224afd916e2b3ac"class="external">Mixnet Incentivization document</a> has been initiated. Current open questions will be addressed, covering system design, mathematical analysis, and more.</li>
<li>Continuing work on the mixnet with staking, incorporating modifications based on feedback. A section has been added concerning the hidden bonus of deanonymization. It’s a straightforward observation that random assignment of adversarial nodes can, in some cases, lead to a higher number of adversarial paths than naively expected. Also, a section about discussing the latency and anonymity relationship has been started. WIP <ahref="https://www.notion.so/Mixnet-with-Staking-c8ec3bfd461f4989b3ebbcf4b4b15324#2e57424c79bd44b19c4c4dd624f544b2"class="external">document</a>.</li>
<li>Analysis of the fraction of compromised paths in the mix network: using an asymptotic lower bound to estimate the probability that the fraction of compromised paths, α, belongs to the interval [α0,α1]. The analysis suggests that in the mixnet of size n=240 with L=3 layers sampled from N=800 nodes, where M=200 nodes are adversarial, α can be almost three times larger than the average (M/N)L which assumes a mixnet of infinite width. The parameters n=240, L=3, and N=800 are currently used in Nym’s mixnet. Here for ¼ of adversarial nodes, the fraction of compromised paths can be as high as 0.05. To compare, the average here is 0.02. Summary is provided <ahref="https://www.notion.so/Analysis-of-failures-in-the-mix-network-feeef349720842759c59785af71c7c59?pvs=4"class="external">here</a>.</li>
<li><ahref="https://github.com/logos-co/nomos-node/pull/569"class="external">All PRs</a> for Mixnet v1 implementation have been merged. We’ve taken some additional time to polish the code according to feedback.</li>
<li>One remaining PR we are working on is adding a compilation option to enable mixnet. We’re going to always enable mixnet in production, but we’ve discussed that it’s also good to remain in the libp2p-only compilation mode for development to unblock other dev topics until everything of mixnet becomes stable. Will be finished this early this week.</li>
<li>Finished RS core encode/decode: there was an issue with different FFT calls from different libraries that didn’t work and took a while to debug. They use floating numbers, and when rounding or using a big set of operations, precision leads to errors - <ahref="https://github.com/logos-co/nomos-specs/pull/75"class="external">PR</a>.</li>
<li>Implemented DA protocol encoder: <ahref="https://github.com/logos-co/nomos-specs/pull/76"class="external">PR</a>.</li>
<li>Implemented DA protocol verifier: <ahref="https://github.com/logos-co/nomos-specs/pull/78"class="external">PR</a>.</li>
<li>DA API mempool tests using a mock implementation <ahref="https://github.com/logos-co/nomos-node/pull/604"class="external">PR</a> - The previous PR defined an abstraction for verifying and filtering what to include in the generic mempool; this PR provides mock implementations for TX and Cert verification/filtering. WIP: DA API indexing for data blobs - adding an index to data blob in DA node when the certificate is observed in the block.</li>
<li>We have begun a couple of study documents in terms of the Coordination Layer: <ahref="https://www.notion.so/What-does-it-mean-for-an-asset-to-be-inside-a-Zone-a38134e2667e43fb80ccf6df0e3d1def"class="external">What does it mean for an asset to be “inside” a Zone</a> and <ahref="https://www.notion.so/Illustrated-guide-to-Mutator-Sets-and-their-Application-to-Scalable-Privacy-17236ccd86994a03b8a4541ea0341a6d"class="external">Illustrated guide to “Mutator Sets and their Application to Scalable Privacy</a>. With these documents, we want to solve questions and challenges before delving into the design.</li>
<li>The “Parallel Zero Knowledge Virtual Machine” paper has been reviewed, and a brief summary of GKR details has been shared.</li>
<li>Explorer works well now, can share the data directories with the node, and provide data through HTTP: <ahref="https://github.com/logos-co/nomos-node/pull/603"class="external">PR</a>.</li>
<li>Nomos has a new <ahref="https://hackmd.io/@Nomos"class="external">HackMD</a> account - our team will be publishing various notes on it - mostly scientific in nature.</li>
<li>Blog to be released this week. Stay tuned on our website.</li>
