P2P Transmission Methods by Oscar Lafarga. Watch now:

Copy-pasting is easy enough... Animated QR codes are cool too! What else can we do? In this workshop we'll explore different ways of transmitting ecash from one device to another, particularly mobile devices in low-connectivity environments. - Text-based transmission (copy-paste & send) - Visual transmission (animated QR codes) - Audio transmission (wtf? is this even possible?)

Un-custody: A New Approach To Permissionless Transactions by Periwinkle Doerfler. Watch now:

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.

Deep dive into BIP324 by stratospher @spherostrat.

BIP324 is Bitcoin's new P2P transport protocol which features opportunistic encryption, a mild bandwidth reduction, and the ability to negotiate upgrades before exchanging application messages. We'll look into the intuition behind constructing the initial v2 handshake between nodes and encryption schemes used for constructing network messages.
