Changelog

All notable changes to this presentation are documented here. Versions follow the slide-set release pattern: vMAJOR.MINOR.

v0.3 — 2026-05-28

SPRIND Funke + wwWallet integration. Reframed the deck around the observation that BMI’s mobile-app-only design is one choice among several that Germany itself prototyped — and that a Linux-compatible web wallet (wwWallet) was demonstrated at the German federal innovation agency’s own EUDI Wallet competition.

• New slide Two Tracks of German Wallet Work establishes the framing early: SPRIND ran a 15-month exploration competition (2024–2025) that closed before BMI’s production wallet ships (November 2026)
• New section SPRIND Funke: The Prototype Competition describes the three-stage open competition, funded and non-funded tracks, jury, and the source artifacts at gitlab.opencode.de/funke
• New slide Funke Finalists: Architectural Diversity shows that three of four finalists built mobile-app wallets in the same shape as BMI’s design and one (wwWallet) built a browser-based wallet
• New three-slide wwWallet arc: project overview and live demo; WebAuthn PRF as the cryptographic replacement for Android Key Attestation; what works on a Linux phone today
• All BMI-specific slides renamed to make scope explicit (e.g. BMI’s Trust Chain instead of The Trust Chain)
• Paths Forward rewritten to list wwWallet first (“Works today: Yes”) and to order options by political rather than engineering cost
• Summary rewritten around “the architecture problem is solved already; what remains is policy”
• References expanded with wwWallet repos, SPRIND Funke pages, openCode funke gitlab, and WebAuthn Level 3 spec
• 4 wwWallet repositories registered as git submodules

v0.2 — 2026-05-25

Polish, accuracy, and accessibility pass.

• Hyperlinks rendered in NavyBlue with a small superscript ↗ to mark external destinations (applies automatically to every [text](url))
• Summary slide split into Layered Picture and Takeaway to fix page-22 content cutoff in the previous release
• Takeaway reworded from “the good news” to a more sober formulation acknowledging that policy/implementation blockers are no easier to shift than technical ones
• All references to BMI architecture v0.7.0 updated to v0.9.1
• Title page expanded with Mastodon URL and project repository URL
• Build pipeline (meson + Pandoc Beamer with lualatex) and GitLab CI release flow added in companion infrastructure commits

v0.1 — 2026-05-23

Initial release. First public version of the slide set.

• Coverage: EUDI Wallet overview, eIDAS 2.0 mandate and timeline, actor landscape, BMI’s trust chain and key architecture (local and remote WSCD), three blockers for Linux phones, Waydroid and ATL analysis, paths forward (RWSCD policy relaxation, web wallet), and references
• Warsaw Beamer theme with DejaVu Sans via lualatex
• Author block, CC BY-SA 4.0 disclaimer, and Discussion slide
