The LNP-BP Standards Association is a non-profit body that develops and maintains specifications for Bitcoin and Lightning Network protocols, most notably the RGB smart-contract system and client-side validation. It curates the LNPBP specification series covering layer-2 and layer-3 constructs that extend Bitcoin without altering its base consensus. The association coordinates the engineers and researchers building these client-side-validated protocols.

- Its work centres on client-side validation, where contract state is kept and verified off-chain while Bitcoin transactions provide commitment and ordering. By publishing open LNPBP specifications the association enables interoperable RGB asset and smart-contract implementations.
