Blind Off-chain Lightweight Transactions (≠ "BOLT": Lightning RFC )
no need for zero-knowledge proof
any real privacy provided by BOLT fundamentally depends on channel establishment and closure being anonymous
Giulio Malavolta, Pedro Moreno-Sanchez, Aniket Kate, Matteo Maffei, Srivatsan Ravi
the foundations for privacy and concurrency in PCNs, presenting a formal definition in the Universal Composability framework as well as practical and provably secure solutions

the running time for the prover from 600 ms to 309 ms
the running time for verifying from 500 ms to 130 ms
Multi-Hop HTLC does not require changes to the current Bitcoin scripting system
