Didactyl will support local inference, which is very privacy preserving. Remote inference does however have it's advantages, and in those cases Didactyl supports using Bitcoin Lightning and eCash inference providers.
## Current Status — v0.1.17
## Current Status — v0.1.18
**Active build — this project is barely working. Experiment at your own risk.**
> Last release update: v0.1.17 — Fix Cashu v4 token field encoding (i bytes, s text, c bytes) and rebuild nostr_core_lib integration
> Last release update: v0.1.18 — Auto-clean spent Cashu proofs in check_proofs, publish deletions, and add spent token events to kind-10000 ignore list
- Connects to configured relays with auto-reconnect and relay state transition logging
- Publishes configured startup events per relay as each relay becomes connected
