Cashu is a layer on top of lightning and allows to do offline bitcoin payments using blind signatures. Look here: https://cashu.space

Pros:
- offline bitcoin payments
- 100% private and anonymous
- can not be censored
- is like cash money (you can print your sats on paper)

Cons:
- you need to trust a mint (but if you want you can host your own)
- you need to be online to verify the validity of an incoming transaction code
