Functional Bitcoin Vancouver 1.5

We held our meeting 1.5 on Tuesday, August 5th, 2025. After a 7-month hiatus since our first meeting.

Topics Discussed

We discussed the best way a group such as ours can have an impact, what we can produce such as communication/education materials, an environment to study and share ideas, and a place to build.

Layer 2 Scaling Solutions

We discussed and compared various Layer 2 scaling solutions:

  • Ark - Virtual UTXOs and covenant-based scaling
  • Spark - Stateless invoices and privacy improvements
  • Lightning Network - Recent updates and developments
  • Taproot Assets - Asset issuance on Bitcoin

Demo: Taproot Assets Bepsi Machine

We demonstrated a working Bepsi vending machine that accepts Taproot Assets for payment. The machine successfully processed beverage purchases using assets issued on Bitcoin and routed through Lightning channels.

Next Meeting

Stay tuned for details on our next meetup in late August.
