Splicing is a two-party feature: Both parts of the channel needs to support it.

2023: Splicing in CLN

2024: Splicing in Eclair

2025: CLN & Eclair are interoperable

Following on Main Stage at nostr:npub1dwah6u025f2yy9dgwlsndntlfy85vf0t2eze5rdg2mxg99k4mucqxz7c52 Lightning++ Edition: Dusty Daemon of Core-Lightning with "Splicing Lightning"

6) Floresta as a Backend for NLightning: Trying to integrate a lightweight local chain-source for NLightning

5) REKTBOT 9000: Autonomous AI agent going full degen on leveraged Bitcoin futures. Balance hits zero = permanent death.

4) Glacier Wallet: Send your bitcoin to the future creating time-locked transactions with CHECKTIMELOCKVERIFY

3) Nuts are pure signal: Signal is an open source project. We replaced its "mobilecoin" integration with a cashu wallet, while still retaining the mobilecoin UI.

2) Mandel: Scaling Lightning privacy with OpenID Connect

1) Obfusats: Complicating Lightning traffic analysis using cashu mints and obfuscation

NLightning goal for the end of 2026 is to have a library that integrates at least 75% of the specification.

For the near future, NLightning wants to offer enterprise level support.

.NET is powerful.

It is used by the main banks in the world (i.e. JPMorgan, BoA), Stack Overflow, Unity. Also in the Bitcoin space, like BTCPayServer!

A .NET Lightning implementation reduces barriers for companies to run their own infrastructure, integration is easy, performances are great.

People think that .NET is Microsoft property. It is not, it is open-source, and OS alternative exists for Linux for compilers and implementations.

.NET design principles: interoperable, language independent, has type safety, portable and has its own security mechanism.

On a daily basis, Blockstream consumes around 72 TiB/day of data from the main chain to keep all the nodes up-to-date.

This is done on just two bitcoind instances!

Blockstream runs many nodes, with no control on any of the funds of the user, nor of his keys:

It's a VLS signer on the user side that talks to hsmd through a proxy to use the node.
