Just-In-Time (JIT) channels

JIT channels are virtual LN channels hosted by a service provider. When the first payment to the channel is received, the service provider creates a funding transaction and adds the payment to it, creating a normal channel. This allows new user to begin receiving funds over LN immediately.

JIT channels should not be confused with JIT routing, which is a technique for rebalancing existing channels to allow accepting payments that might naively need to be rejected.
