Splicing in LDK. "The goal of ldk-splicing is to add splicing support to LDK in an interoperable and pragmatic way."

Bitcoin Core Testing Suite. "The Bitcoin Core Testing Suite aims to increase the coverage and robustness of Bitcoin Core’s testing suite."

BLAST. "The “Big Lightning Automated Simulation Tool” (BLAST) is a modeling and simulation framework specifically designed for the Lightning Network. The primary objective of this project is to conduct research and development to devise an efficient representation of nodes and channels." Scaling Lightning. "Scaling Lightning is a framework for creating and interacting with test lightning networks. The project aims to provide a realistic lightning network environment for developers to build and develop their applications and services."

Satsigner. "Satsigner is a mobile wallet that aims to give the user full control and visibility over what is happening to their sats at the protocol level."

Firebolt Wallet. "Firebolt is a wallet that supports both on-chain and lightning transactions. It runs a custom non-routing Lightning node on the user’s mobile device and integrates with your nostr contacts. Firebolt is fully non-custodial, supports CoinJoin and PayJoin transactions, and integrates with peer-to-peer marketplaces such as Bisq, Peach, and RoboSats.

The Bitcoin LARP Game. "The world-famous Bitcoin LARP is a game designed to understand the inner workings of Bitcoin in a fun and interactive way. The goal of this project is to have open-source kits available to anyone that are easy to replicate, use, and set up."

Braidpool. "Braidpool is a decentralized bitcoin mining pool. Braidpool aims to ship an implementation working on signet with hashrate donated by interested miners. The Braidpool proposal builds upon Schnorr signatures and Taproot, as well as novel peer-to-peer research. Braidpool enables all miners to do their own block construction and miner payouts can not be blocked by a central authority like a pool operator."
