Favorite bitcoin review so far. Insights:
- ecash = lightspeed-fast bearer token, can be useful at any project-scale
- pears.com = SDK and NOT an open protocol, hypercores are very useful P2P tech though #stealit
- npub = lightning address, whether you know it or not
- npub = no need for DNS
- JSON first for adoption, but binary = inevitable
- Coldcard Q + Satslink + ecash = Star wars
