After day one ad two, here the third day of the Bitcoin++ Lightning conference in Berlin, featuring presentations on Lightning Network scaling, implementations, and hackathon project showcases.
Had no time to add the links to the video chapters, however, hope having a reference on the timestamps for each talk helps.
Christian Decker from Blockstream open the floor with Greenlight, a Lightning-as-a-Service platform that runs individual Core Lightning nodes for each user while keeping private keys segregated, allowing nodes to operate on-demand rather than 24/7. The system currently supports 250,000 nodes by leveraging an "always-on illusion" where nodes spin up in about one second when needed. Nicholas Golen demonstrates his .NET Lightning implementation called "EnLightning," designed to bring Lightning to enterprise environments familiar with Microsoft technologies, targeting banks and financial institutions that already use C# developers and .NET infrastructure.
Dusty presents "Splice Script," a new syntax for creating complex Lightning channel splicing operations that enables moving funds between channels, opening new channels, and making on-chain payments directly from Lightning balances without closing channels. The system aims to make advanced splicing operations accessible to more users through simplified scripting. Calle demonstrates Cashu's integration with Lightning, showing how ecash tokens can provide privacy-preserving payments through blind signatures while maintaining Lightning interoperability for cross-mint transactions and atomic swaps.
The hackathon presentations showcase six finalist projects: Obfusats (privacy-preserving payment mixing through casual mints), Mandal (KYC-compliant ecash mint), Nuts are Pure Signal (Cashu payments integrated into Signal messenger), Glacier Wallet (Bitcoin time-locking), Rectbot 9000 (AI trading bot), and Floresa backend integration. A panel discussion with core Lightning developers from different implementations (Core Lightning, LDK, Eclair, and EnLightning) covers the evolution of Lightning development, implementation differences, and future protocol improvements like gossip v2, multi-party channels, and zero-fee commitment transactions. The conference concludes with "Nuts are Pure Signal" winning first place in the hackathon for successfully integrating Cashu ecash payments into the Signal messaging app.
