SeedSigner + BIP-353: Human-Readable Bitcoin Payments

[alvroble]

Description

What is this talk about? Give us as many details as possible

BIP-353 removes payment friction. Bitcoin users increasingly demand human-readable payment addresses, but existing solutions are fragmented and error-prone. BIP-353 leverages DNS and DNSSEC to map readable names to payment instructions, enabling secure, verifiable, and privacy-friendly payments that hardware wallets can validate easily, dramatically improving the user experience.

In this talk, we will explore BIP-353: DNS Payment Instructions from the perspective of implementation in a hardware wallet like SeedSigner.

The following points will be addressed:

• Introduction to BIP-353: what it is, its motivation, and the problems it seeks to solve in UX.
• Benefits for users and developers: reduction of friction in payments, decentralization, and DNSSEC security against impersonation.
• Implementation in embit: how BIP-353 was integrated into the embit library, a key piece of SeedSigner.
• Use of Rust in a Python project: integration of the dnssec-prover project within embit, an interesting approach that opens the door to future combinations (e.g., BDK).
• Implementation in SeedSigner: development of UX for DNSSEC proof validation in SeedSigner
• Lessons learned: technical challenges, trade-offs, and future directions for SeedSigner and the ecosystem towards BIP-353 adoption.

What would an attendee learn from this talk?

Participants will leave with:

• A clear understanding of what BIP-353 is and how it works.
• An understanding of the benefits of BIP-353 for Bitcoin UX.
• Practical knowledge on how to integrate Rust libraries into Python projects.
• Inspiration to apply this approach in other ecosystem projects (e.g., wallets, libraries).
• A vision of how to improve interoperability between Bitcoin tools.

Is there anything folks should read up on before they attend this talk?

(Not strictly necessary, but recommended)

• Basic familiarity with the Bitcoin ecosystem.
• Review of the text of BIP-353.

@alvroble Thanks for the submission! Unfortunately, we can't fit this into the schedule as it stands. That said, since it looks like you could potentially deliver this talk in 15 minutes, I'm going to keep it open as a standby. If we get a break in the schedule or a cancellation, I'll consider slotting it in.

I can't promise acceptance, and you shouldn't expect it, but we should know more in the days leading up to the conference.

@miketwenty1 Thanks for your update and for keeping my submission on standby. I completely understand the constraints. I wrote an article covering the topics I intended to explore in the talk, and I thought it might offer useful context. You can check it out here.
