Private PoS §

• Updated draft addressing comments related to shielded and transparent transaction types.
• Defined an opportunistic voting problem.
• Continuing analysis on zCash transaction’s construction.
• 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.

• Minor issue on integration tests fixed: https://github.com/logos-co/nomos-node/pull/315

Data Availability Sampling §

• Studied RS+KZG in context of our DA architecture.
• 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.
• 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.
• Created a simplistic API for RS: https://github.com/logos-co/nomos-node/pull/303
• Created a simplistic API for KZG: https://github.com/logos-co/nomos-node/pull/309
