• Reversed schema hierarchy (see details in last call agenda, https://github.com/LNP-BP/devcalls/blob/master/2020-09-30-agenda.md#schema-genesis-versioning)
• Public state extensions: decentralized issuance & "call to contract method"
  • Issue: LNP-BP/LNPBPs#52

  • implementation for RGB data: https://github.com/LNP-BP/rust-lnpbp/blob/master/src/rgb/bech32.rs

Finalization of the decisions

• LN asset naming & divisions
  • naming: LNP-BP/LNPBPs#60
  • divisibility: LNP-BP/LNPBPs#51 NB: what about NFT sub-divisibility for LN?
• LNPBP-1 & 2 refactoring: keyset commitments:
  • proposal: LNP-BP/LNPBPs#48
  • other changes to LNPBP1: LNP-BP/LNPBPs#66
  • LNPBP1 changes: LNP-BP/LNPBPs#67
  • LNPBP2 update is WIP
  • implementation: LNP-BP/rust-lnpbp#125
• PSBT custom keys: one removed (fee), the second one, keeping tweaking factor is replaced with non-proprietary; which is planned to be added to BIP-174 standard
• Universal protocol for node oprations (RGB, LNP, Bifrost ...): node ids, compatible messaging system & message ids (see details in last call agenda) LNP-BP/LNPBPs#55
• UDP hole punchng discussion results LNP-BP/LNPBPs#39

Protocol future

• NFT transfers in generalized LN with channel factories
• Sign to contract instead of pay to contract commitments LNP-BP/LNPBPs#65
• MW-like Pedensen commitment aggregation for the historical data LNP-BP/LNPBPs#57
• Merge-mined chain allowing excellend scalability with single-key-per-block concept

Related updates from other projects
