What is the approach of RGB architecture?

[UkolovaOlga]

RGB uses paradigm-based approach:

• Layer isolation via abstraction
• Layer interaction via strictly-defined interfaces
• No future hardforks, just a single release

Common development/coding architecture paradigms used for RGB:

• Strict encoding: LNPBP-6
• Single-use seals: LNPBP-7
• Cryptographic commitments: LNPBP-8
• Client-side verification: LNPBP-9
  Paradigms descriptions can be found in 
GitHub here

RGB applies these general paradigms to Bitcoin transaction graph

• Single-use seals: transaction output-based seals (LNPBP-10; lnpbp::bp::txo_seals)
• Strict encoding: RGB consensus encoding (LNPBP-11; lnpbp::rgb::*)
• Cryptographic commitments:
  • deterministic bitcoin commitments (LNPBP-1, -2, -3; lnpbp::bp::dbc)
  • multi-contract commitments (LNPBP-4; lnpbp::lnpbps::lnpbp4)
• Client-side verification:
  • RGB schema (LNPBP-12; lnpbp::rgb::schema)
  • RGB contracts 
(LNPBP-13; lnpbp::rgb::{transition, stash, ancor, consignment})
