LNP/BP Library

The repository represents a set of libraries implementing LNP/BP specifications https://github.com/LNP-BP/LNPBPs not fitting into a scope of other existing LNP/BP core libraries (client-side-validation, BP, LNP, RGB, invoicing). It can be used to simplify development of layer 2 & 3 solutions on top of Lightning Network and Bitcoin blockchain.

Currently, the repository contains the following crates: - lnpbp_bech32: library implementing LNPBP-14 standard of Bech32 encoding for client-side-validated data. - lnpbp_chain: library providing chain parameters for bitcoin-related blockchains; - lnpbp_elgamal: library implementing LNPBP-31 standard for ElGamal encryption using Secp256k1 curve; - LNPBP umbrella crate containing all aforementioned libraries.

Other libraries, implementing LNP/BP specifications, not included in this crate: - Client-side-validation foundation libraries (client_side_validation) - Bitcoin protocol core library (bp-core) - Lightning network protocol core library (lnp-core) - RGB core library implementing confidential & scalable smart contracts for Bitcoin & Lightning (rgb-core) - Universal invoicing library

The current list of the projects based on these libraries include: * RGB Node * LNP Node enabling: - RGB extensions - DLC extensions - Lightspeed payments - Multi-peer channels - Faster lightning experiments (quicker adoption of eltoo, Taproot etc) * BP Node: Indexing service for bitcoin blockchain; more efficient & universal Electrum server replacement. In perspective - validating Bitcoin network node (using libbitcoinconsus)

Potentially, with LNP/BP libraries you can simplify the development of * Discreet log contracts * Implement experimental lightning features * Do complex multi-threaded or elastic/dockerized client-service microservice architectures

The development of the libraries is supported by LNP/BP Standards Association.
