First on Main Stage at@btcplusplus Lightning++ Edition:@Michael B of @Blockstream with "The Lingua Franca of Bitcoin: Lightning for Operators, not Wallets".

NEW: The filter wars started with discussions around Citrea’s impending use of OP_RETURN for their BitVM implementation. While observing the battlefield, bitcoin++’s resident rollup enjoyer, Janusz noticed there was some misconceptions around Citrea’s construction. When thinking about bitcoin rollups, we have to separate the bridge from the actual rollup implementation. Rollups are sovereign execution layers that use bitcoin for data availability. Bridges bring BTC onto the rollup execution environment. Like any design, there are tradeoffs for building a rollup. In his latest Scaling Bitcoin piece, Janusz provides an overview on Citrea’s state transition function and shows how Citrea nodes finalize transactions based on data posted to bitcoin.

NEW: ArkadeOS took Riga by storm having merchants receive Arkade VTXOs instead of Lightning balances. Conference goers were completely unaware that this was happening in background due to Arkade's @Boltz - Non-Custodial Bitcoin Bridge integration. While certainly a win for Arkade, it was also a win for the Lightning Network - the connective tissue enabling all bitcoin layers to interoperate. Janusz breaks it down in his latest 👇

Lightning swaps *are* the connective tissue

Arkade's hijacking of the Baltic Honeybadger point-of-sale system was rightly the event's headliner, but it also proves that Lightning will be bitc...

NEW FROM THE INSIDER EDITION: SPHINCS+ was introduced as a proposal to add a post-quantum signature scheme to bitcoin. There's rough consensus, that at some point, we'll need to transition to post-quantum signatures. SPHINCS+ is a promising path forward. In our latest post, @niftynei() 🇺🇸💸🧡 breaks down the proposal and analyzes its various components. Full post here 👇

NEW FROM THE INSIDER EDITION: Bitch@ is going nuts. Yesterday, we saw a native Cashu wallet built into the Bitchat app. Januszg and co. decided to do a deep dive into the integration and outline some of its real world applications. Our take? It's a promising tool for anonymous, offline bitcoin-denominated payments. Check it out 👇

Knock, knock. It’s Cashu, Bitch@

Calle teased a Bitchat application that natively supports Cashu payments. How does it work?

NEW FROM THE INSIDER EDITION: It might be Paper Bitcoin Summer, but some of us still want private, bitcoin payments. For his latest piece, Januszg covers Shielded CSV - a payments protocol that can be built on top of bitcoin. Tl;dr - it's scalable, pretty damn private, and relies on bitcoin for the ordering of its nullifiers.
