Developer calls

Here you will find links and agendas of RGB weekly dev calls


β€‹πŸ•” Time and day - every Wednesday, 5pm CET* πŸ”— Jitsi link to join the call 🎧 Calls are being recorded and uploaded to the devcalls repository πŸŽ₯ Demos and presentations are uploaded to the YouTube channel *sometimes time and date can be changed, follow the announcements on RGB Telegram Group​


Agenda: 1. Presentation of πŸ”₯RGB computational model (PRISM). 2. Q&A session: - How badly Disclosure process exposes your privacy? - If RGB smart contracts are isolated, can they still cooperate/share information between each other? - If in Stash many parties can contain alternative histories, how to define which history is the true one? - I believe that the RGB20 and RGB21 contracts written in rust already existed before AluVM, will there be a reimplementation of RGB20 and RGB21 in AluVM scripts? - Do you have any further insight into when RGB will work on lightning? etc 🎧 Audio recordings, πŸŽ₯ YouTube video, πŸ“ Presentation slides​


Agenda: Development update and RGB Q&A session. 1. Category Theory resources: introductory course, additional link. 2. Does category theory has impact on AluVM? 3. Is there a standard in RGB (or bitcoin) in denoting a utxo output e.g. in a single use seal? 4. Does a routing node just need to know about the asset, or do the channels have to be for that RGB asset as opposed to regular NTC LN channels? 5. If an asset created with RGB becomes very valuable, or you just have many of them, you might not want to have it on a lightning hot wallet. Since to move the assets, only a regular BTC signature on a PSBT is required, it should be possible to safeguard those assets in the same cold storage as your regular BTC. The only hard requirement to the cold storage is that it can sign PSBTs. I don't think there should be a problem with multisig here. But in order to be sure you sign the right thing, the cold storage should have some knowledge of the assets that are moved. How could this look like? 6 . If i'm reckless, can I use RGB on mainnet? Is there any precedent of issuing rgb asset on mainnet? 7. There is an idea to put a NFT (the RGB equivalent) in an Opendime to transfer some properties physically. So, on the Opendime attached on the artwork you will have the NFT certificate version of the artwork. Can it be possible with RGB NFTs? 8. RGB and existing Lightning Nodes implementations (e.g. LND). 9. DEX devepoment - progress update. 🎧 Audio recordings​


Agenda: 1. Development and documentation updates. - - - - - 2. Q&A session: - How to solve the double issuing problem when the issuing is private? - Will there be a vanity asset id generator? (vanity = with friendly first asset id characters) - How can AluVM optimize or control the behavior of assets in a lightning channel? - Is it possible to use AluVM to write an auction contract "using sats" or bidding? - Can you talk more about the decentralized data storage for RGB21? Who pays for the storage and who will pay for it in the future? 3. Preliminary introduction of the research on Sigchain and Sealchain carried out by Dr. Maxim Orlovsky and Pandora Core AG. 🎧 Audio recordings​

RGB Q&A 1. Could we use RGB tokens as representing the state in a more complex state machine ? A state machine that could be represented by a Directed Graph (allowing cycles), a general petrinet for example. 2. If you lend your bitcoin to some financial institution and then something happens to it, can you use the RGB-bearer right to prove that you are still the holder of bitcoin and get your funds back?

  • Supporting Rust stable and down to v1.41! Removed all unstable language components

  • No more upstream forks, for now dependencies are only on published bitcoin-related crates (miniscript v2, bitcoin v0.25, latest bitcoin_hashes with Taproot updates, removed unstable lightning dependency)

  • SQLite support for RGB Node by @rajarshimaitra

RGB SDK is prepared for the release this week by @zoedberg

Lightning Network

  • Generalized payment channels and relation to RGB and LN Node

  • LNP Node architecture and overall design approach to node architecture

  • Universal protocol for node oprations (RGB, LNP, Bifrost ...): node ids, compatible messaging system & message ids (see details in last call agenda) Explanation on RGB peer network and Bitfrost peer network as a part of Lightning peer network. Considerations and discussions.

  • Generalized Lightning networking on top of alternative transports (Websocket, HTTP overlay, SMTP, messaging) and RPC stack with ZMQ et al

  • Ongoing work on structuring Internet2 stack as a set of Lightning related networking protocols on top of Tor

Wallet integration

  • Explanations on matters related to DBC tweaks of public keys: lessons learned from Liquid Excerpt: After discussion with Andrew Poelstra it became obvious that the previous decision of storing public key tweak information within PSBT as a single value ( will be insecure and incompatible with hardware signing units, wallets or airgapped solutions. The problems is that the device must be able to verify what is hidden behind the tweak, otherwise it will be possible for a malware to change the tweak in such a way that it will substitue the underlying state transition with some other (assigning assets to the thief-controlled UTXOs) or, even, apply some taproot-based alternative spending conditions.

1.RGB Protocol


  • New unified invoicing proposal with protocol layerization, extensibility, interoperability:

    • "Payment specification" layer. Current example - Bitcoin addresses. Will be extended for RGB with new types from this table:

      • Blinded UTXO (RGB-specific)

      • Descriptor-based (can be used for Bitcoin also). Hints:

        • Deterministic key derivation with block height

        • In RGB we can make keys truly random since we know payment txo anyway from the consignment

      • PSBT-based (can be used for Bitcoin!)

      • Channel (LN)-based: not the same as BOLT-11, but just a node id, address and routing hints

    • "Invoce" layer (current example - BOLT-11, parts of the proposed BOLT-12/13)

      • Just an LN message serialized into Bech32 format!

      • Now LN messages can be send over non-interactive or high-latency networks (mesh, satellite, SMTP/mail, messengers/tweets)

      • Very extensible: TLVs, new message types. Making new invoice type is just like defining new LN message: decentralized

    • "Interactive payment protocol" layer (current examples - BIP70, LNURL, BOLT12 from above)

      • Potentially should work with any invoice and data type (it is the case for LNURL already; will try to direct BOLT12 into this; BIP70 is depricated anyway)

      • We will have Bifrost for RGB-related interactivity; it will utilize LN messaging format so complete invoice data workflow (offer/request/invoice/ failback/alternative) may fit into bech32-encoded strings as described below:

  • Bech32 encodings for invoicing & RGB-related data entities

    • Any message can be serialized with <4hex>_lnp1bechdata, or for known formats <id>[_<4hex>_lnp]1bechdata (this is interoperable with Russel new invoices), for instance inv1invoicedata can be a universal invoice message.

    • Bech32 for raw data (non-LN messages) will use normal HRPs, so this is backward-compatible with current Bech32 use, and will fit well with RGB- related Bech32 for hashes (RGB contract id, schema id etc) and data types. See sample implementation in​

    • Public keys & LN node ids can also use Bech32 encoding with pk_ prefixes:

      • pk1keydata - for public keys

      • pkx1keydata - for extended public keys

      • pkn1keydata - for node ids in LN (b/c of the unification, see below, this id will work with LN, RGB network & Bifrost) This can potentially replace multiple formats (WIFs, hex encoded keys, BASE64 encoded xpubs and serve the original goals for which Bech32 encoding was proposed.

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:

    • P2P network differentiation (P2pNetworkIds and NetworkMagic)

    • Layer 1 differentiation: ChainHash and ChainParams

    • Xpub/Xpriv specifics: ChainCode

    • Bringing it all Layer 1 stuff together with single & simple Chain

    • Asset cross-layer differentiation (on-chain ChainHash, Liquid CA, RGB, OMNI): AssetId

  • How it is used:

    • Schema do not commit to anything

    • Genesis commits to chain hash, but stores full set of chain params

    • This is why genesis needs a "data structure version" flag in chainparams field (to allow chain params extensibility), and must represent a list of data, starting from the first version

    • LN nodes uses AssetId as a ChainHash to identify in which "network" they operate/accept channels

  • More LN-specific asset details for asset geneses:​

  • RGB versioning clarification:

    • Schema has a version identifying RGB protocol version An RGB contract genesis (asset issuance) commits to Schema and thus to a specific RGB protocol version forever: no "forks"/version upgrades within single contracts, but different contracts from different issuers may operate on different RGB versions

    • Consignments use "serializetion version" field indicating network serialization format used for data transfer. Receiver specifies desired/ supported formats as a part of invoice data. This allows more efficient compression of network-transferred data (like use of bulletproof/pedersen aggregation, shor bitcoin ids)

    • Genesis uses version for ChainParams field data structure (see above), which has nothing to do with protocol or serialization version. Receiver do not need to specify version in invoice, since all legacy versions are always included.

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.


  • 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

Completed implementation


  • Key management & signing functionality within LNP Node will help wallet devs with this part of functionality. Unfortunatelly 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.

  • Proposals (first, second) for onion messaging BOLT extensions from Rusty Russel for new extensions allowing non-payment (i.e. generic) messaging.

  • Simplicity WIP branch in elements/liquid beta

  • Schnorr signature implementation PR for rust-secp256k1 by Tibo from Digital garage.
