This topic is aimed at chatting about PTLCs, which are basically an enhancement of the current payment system in the Lightning Network known as hash time locked contracts (HTLCs). To break it down, this contract allows for trustless and atomic payment routing. It works by ensuring that the sender will transfer funds to the recipient only if the recipient discloses a secret that produces a certain hash. If the secret isn't shared, the sender can retrieve their coins after a set period. With the Schoor upgrade, implementing PTLCs is now possible.
To help clarify things, I've got 4 slides that explain the whole process really well.
Great infographic, but you might want to post the banners for Adaptor Signatures and Wormhole Attack so that people have a greater chance at understanding of what exactly is at play here. Maybe even link the infographic for HLTCs as well for newbies to cross-reference.
Do you have an idea of when this stuff is hitting the Lightning Network standards officially? or maybe when LN clients will decide to implement it?
@NotATether
as you wished here are 4 more slides about the topic you mentioned 'wormhole attack' also the slides for the 'hashed timelock contracts (htlc)' to see the difference to ptlc i have added as well
more information on the two topics in question can be found here: Wormhole Attack & Hashed Timelock Contracts
Good afternoon, I would like to see a more detailed mathematical proof of either the entire PTLC, or as you suggest with 3 steps. And, if possible, links where the signature adapter is explained more clearly. Therefore, I cannot yet connect your explanation of the PTLC implementation with Rene Pichard's explanation of signature adapters.
