From A.Gangwal at tudelft.nl Fri Jul 17 06:43:45 2020 From: A.Gangwal at tudelft.nl (Ankit Gangwal) Date: Fri, 17 Jul 2020 06:43:45 +0000 Subject: [Lightning-dev] Collaborated stealing. What happens when the final recipient discloses the pre-image Message-ID: <554521DD-25B5-4D13-A351-98A37C89DA01@tudelft.nl> Consider A wants to send some funds to E. They don?t have a direct payment channel among them. So, they use a following path A-B-C-D-E. A is the sender of payment and E is final recipient. E sends the hash of a secret r to A, A passes on the hash to B, B to C, C to D, and D to E. E discloses the secret to C (a partner in crime with E) and E do not respond to D. C gives the secret to B (settling the HTLC between them). Then, B gives the secret to A (settling the HTLC between them). A sent (and lost) the money, as E denies receiving the money (and the promised service/good). How the lightening network sees this? Out of their control? -- A_G -------------- next part -------------- An HTML attachment was scrubbed... URL:
