Rose: A stateless light wallet for businesses: private by construction, attested at runtime

This talk introduces Rose, an open-source light wallet for self-custody and e-commerce. Rose exposes Bitcoin Core's RPC dialect, so existing payment integrations work unchanged. Unlike Electrum- and Esplora-backed wallets, Rose syncs over BIP-157 compact block filters and adds a live mempool feed for incoming-payment notifications, giving fast sync and 0-conf visibility without ever sending an address to a third-party server. It is stateless: the wallet is rebuilt from a seed, a derivation path and a birthday. That property is what lets Rose run inside a trusted execution environment, where the seed is released only to an attested, reproducible image, and where spending policies for e-commerce workflows can be enforced by code a counterparty verifies from the build hash. We walk through what a light wallet leaks, what it cost to close each leak, and what an enclave does and does not protect against. Rose is built in Rust on BDK, Kyoto and StageX.

NostrMail - Learning from three decades of PGP

NostrMail is a cross-platform, end-to-end encrypted email client that bridges Nostr and traditional email protocols. It avoids the pitfalls of PGP by using Nostr for key discovery, it works with existing email providers like Gmail and uses wordlist encoding (e.g., BIP39) so ciphertext and signatures remain valid under forwarding. NostrMail is open source, cross-platform, and available now on the Zapstore.

Intro Hashrate Accounting: Mining for the masses

This talk explores the concept of Hashrate Accounting and its potential to enhance Bitcoin privacy and expand mining operations. Beginning with an examination of the Bitcoin mining network's massive scale (600 exahashes/second), we'll discuss how hashrate marketplaces function and why miners sell their computational power. The presentation explains the role of hashrate proxies in facilitating forward privacy on-chain. Finally, we'll explain how Rigly brokers hashrate between miners and retail customers, and how we are facilitating the expansion of mining operations in areas with stranded energy.

NostrMail - PGP for the plebs

NostrMail is a simple email client that pairs Nostr DMs with encrypted emails, thereby providing a mechanism for long-form content, file sharing and archival storage. We'll demo our proof of concept running in docker, discuss our technical implementation, NIP and planned features, including 2-factor authentication, key rotation, and multi-party conversations.

Demystifying Elliptic Curves

Elliptic curves play an integral role in Bitcoin transactions, but you don't need a degree to understand them. We'll break down the discrete log problem using interactive visual notebooks that illustrate the key concepts. This workshop is aimed at all skill levels, so bring a friend.
