• Skynet/Sia decentralized storage was evaluated as a possible backend for “gitchain,” a hypothetical distributed version-control system; SkyDB (a mutable decentralized database layer) was highlighted as a relevant component.  
• A Beilstein Journal paper on “Encrypting messages with artificial bacterial receptors” was dismissed as a poorly designed pseudo-random-number generator, illustrating skepticism toward biological cryptography claims.  
• Google’s XLS high-level synthesis toolchain was discussed for FPGA work; participants noted it emits Verilog and has been demonstrated on Lattice iCE40 parts, but still requires manual wrapper code for clocked logic.  
• The recent theoretical breakthrough in indistinguishability obfuscation (iO) was summarized: although currently impractical, success would enable witness encryption, functional encryption, and deniable encryption, with a Quanta Magazine article provided for background.  
• PostgreSQL’s Serializable Snapshot Isolation (SSI) and predicate-locking mechanisms were dissected as examples of how databases provide strong transactional guarantees, prompting the broader question of why application software rarely exposes similar transactional interfaces.  
• A novel accounting model was proposed in which value is represented by discrete, indivisible tokens instead of numeric balances, aiming to eliminate accidental creation or destruction of units during transaction failures.  
• Google’s libprotobuf-mutator, a library for fuzzing protocol-buffer inputs, was shared as a tool for robustness testing.  
• Participants lamented Twitter’s impending shutdown of its legacy web interface on 15 December 2020, framing it as another step toward user-hostile software ecosystems.
