SuperScalar: Laddered Timeout-Tree-Structured Decker-Wattenhofer Factories

Thus, this scheme also provides an “assisted exit” where, in exchange for the client keys in this construction, the LSP assists the client to get an onchain UTXO, or to move to a new factory in the ladder. This is done by using PTLCs to swap, with the scalar being the private key.

How can you trust the LSP to fee-bump just-on-time for the end user and the LSP won’t maliciously abort the private key handover ?

“Fair exchange” of a secret is an unsolved problem since 90s’s distributed system literature.
