7 Oct	1. Roadmap: - new release roadmap - explanation of the relations between LNP/BP Core lib and RGB Node/SDK - RGB Core roadmap - RGB LN roadmap - RGBv1 and what it means 2. Releases: - Amplify - Docker containers big update: Bitcoin Core, c-Lightning, ElectrumRs, Elements & RGB Node - readiness of LNP/BP Core Library first release (v0.1) - updates on RGB security audit started last week 3. Decisions taken throughout the week & implemented: - RGB versioning: Schema feature bits - Storage of whole chain parameters in Genesis, committing only to chain hash - Reversed schema hierarchy - Public state extensions: decentralized issuance & "call to contract method" - Changes to bulletproofs from the week before - Bech32 encodings for RGB & invoicing 4. Protocol future: - NFT transfers in generalized LN with channel factories - Sign to contract instead of pay to contract commitments - MW-like Pedersen commitment aggregation for the historical data - Merge-mined chain allowing excellent scalability with single-key-per-block concept 5. Related updates from other projects: - proposals for onion messaging BOLT extensions from Rusty Russel for new extensions allowing non-payment (i.e. generic) messaging - Simplicity in elements/liquid beta - Schnorr signature implementation PR for rust-secp256k1 by Tibo from Digital Garage.	Audio
30 Sep	1. RGB protocol Invoicing: - New unified invoicing proposal with protocol layerization, extensibility, interoperability - Bech32 encodings for invoicing & RGB-related data entities Schema, genesis, versioning: - Schema extensibility for things like multiple asset schemas: instead of extending schema, we will have one "most advanced" schema with all features (for assets, NFTs, reputation etc) and smaller sub-schemas which will commit to the most advanced schema for which they are just a subset. It will resolve security considerations by Alekos Filini and allow simple wallet adoption of new asset schema types. - Interoperability & networks explanations and structuring - How it is used - More LN-specific asset details for asset geneses - RGB versioning clarification Protocol unification: - Proposed invoicing protocol operate not only with RGB, but also can be used for native bitcoin on-chain and LN payments - API/message type unification for RGB Node, Ligthning network (all nodes) and future Bifrost. Now node type will be defined just by the set of features, and networks can inter-operate - RGB Node, LNP Node and Bifrost will be unifiable into a single piece of software, so wallet devs will be able to use just a single integration point to run RGB onchain, RGB lightning & native lightning payments Other: - Decentralized issuance & "call to contract method": public extensions to RGB contract state proposal & PR to the Core Library Mimblewimble-style Pedersen commitment aggregation & history cut-through better privacy concept for the future & updated RGB scalability roadmap 2. Dev updates Notable releases: - amplify & amplify_derive crates v1.0 release with extensive test coverage using GitHub actions. Repo: https://github.com/LNP-BP/rust-amplify Updated Docker images for bitcoin, c-lightning, elements, electrs & RGB Node with better Signet support released to Docker Hub and GitHub Completed implementation of Bulletproof commitments (implemented and merged) WIP: - Key management & signing functionality within LNP Node will help wallet devs with this part of functionality. Unfortunately we can't use BDK since it lacks RGB specific PSBT key type support (for Pk tweaks) and Xpub/Xpriv other chains, so LNP/BP Core library will include special mod for all necessary extensions to Xpub/Xpriv keys and PSBTs, as well as signers, based on miniscript, supporting necessary RGB functionality. See sections above on more details to Xpub/Xpriv specifics - Better test coverage approaching ~60% for the Core Library and ~100% for the underlying amplify crate, including new exhaustive tests for some encodings covering all possible encoding options - Better code docs: ~50% for the Core Library & 100% for the underlying amplify crate	Audio
23 Sep	1.

Closing old discussions: Monero buletproofs, lexicographic output ordering. 3. CI & infrastructure: Dockerization (full set up images), Signet & Lightning, exhaustive tests 4. Future protocol developments: Zk: bulletproofs aggregation, decentralized issuance with public transitions 5.
