LaWallet: a NOSTR-Backed Lightning Wallet by Mariano Perez Rodriguez. Watch now: https://youtu.be/Ba3DpzUAopA
"How can Lightning reach the whole world? How can non-tech-savvy users be on-boarded? How can familiar payment UXs be leveraged? How can NOSTR help us be shamelessly transparent?" These were the questions we tried to answer with LaWallet: an Open Source, transparent, custodial, Lightning wallet, with built-in BoltCard support. Join us as we visit the inception, design rationale, protocols, and future extensions of this modular machine.
This presentation was recorded in Buenos Aires, in February 2024 during bitcoin++ payment edition.

Building a Custodial Lightning Wallet the Right Way by gudnuf. Watch now: https://youtu.be/QTXYN3BaH2Q
Traditional Lightning wallets offer a stark choice: complex and non-custodial or privacy-compromising and custodial. Cashu bridges this gap, enabling developers to build user-friendly Lightning-enabled apps without the usual complexities. In this hands-on workshop, with the help of cashu-ts and Replit, participants will implement sending and receiving Lightning payments while exploring privacy features, offline capabilities, multi-currency support, and user-selectable custodians.

Un-custody: A New Approach To Permissionless Transactions by Periwinkle Doerfler. Watch now: https://youtu.be/dZxwpsKqSGs
There are currently two main approaches to Bitcoin custody: self-custody, e.g. the use of non-custodial wallets or cold storage, and centralized custody, through trusted 3rd parties and multisignature schemes. In an abstracted environment (which maintains Bitcoin finality and proximity) there is a third option: un-custody - or custody-by-consensus - a custody scheme completely foregoing cryptographic proofs. This talk explores un-custody and its benefits and applications, particularly with respect to DeFi systems like ecash implementations.

Replace by Fee-Rate by Peter Todd. Transaction pinning is potential threat to many multi-party protocols such as lightning. Yet it's also an economic exploit: miners are leaving money on the table. Here we'll look at replace-by-fee-rate, an incentives-based solution to pinning that both fixes the problem, and earns miners more money.

Simple Layer Twos by Christian Lewe. Watch now https://youtu.be/yPkGjpvofNM
Christian Lewe of Blockstream Research (clewe) presents on: Simplicity is a proposed overhaul of the scripting language of Bitcoin. It fundamentally changes what can be done on layer one, but it does not stop there. Given what was possible with the existing scripts so far, imagine the explosion of ideas that Simplicity would enable. In this talk, we explore some of those applications, including Validity rollups and Fedimint accounts.

Building Compact Bitcoin Index by Micaiah Reid @hirosystems. This presentation was recorded in May 2024 in Austin, TX during bitcoin++ conference, script edition. Watch now: https://youtu.be/LjaCi7rL_fQ
One of the biggest pain points we see from developers building on Bitcoin is indexing the chain. Many devs have to maintain their own index of blockchain chainstate, which can incur high storage costs and be challenging to keep up to date. Re-orgs of chainstate happen often, and every time there’s a re-org, you have to re-index the entire chain, which can be a time-intensive process. At Hiro, we built an open source indexing engine (Chainhook) that enables anyone to build consistent, reorg-proof databases that index only the information you want— creating a lighter-weight index. In this workshop, we'll show you how to create individual "chainhooks" to filter and trigger specific actions based on on-chain events.

The Great Script Restoration Project by Rusty Russell @rusty_twit. This presentation was recorded in May 2024 in Austin, TX during bitcoin++ script edition.
You're probably aware that v0.3.1 of Bitcoin disabled numerous Script opcodes, most famously OP_CAT. Bringing them back unlocks a great deal of power, and there are a few additional opcodes that complement them well in a modern Bitcoin system (such as key addition). This talk aims to present a coherent model for making Bitcoin Script as capable as I think it can be, while avoiding the pitfalls which caused it to be hobbled in the first place.
