The email exchange between Subhra Mazumdar and ZmnSCPxj centered on the topic of privacy and security in payment systems. Specifically, Subhra expressed concerns about relying solely on the sender for sampling secrets and generating PTLCs in anonymous multi-hop locks. She was worried about layer-crossing shenanigans that could compromise the privacy of payments.In response, ZmnSCPxj explained how both the sender and receiver control the secrets in PTLC-based payments, making it less vulnerable to attacks from a single entity. He also addressed the concept of griefing attacks and how they are only possible by not claiming or forwarding the attack. Throughout the discussion, the importance of protecting privacy and security in payment systems was emphasized. The email exchange did not provide any details about what specifically sparked this conversation, but it is clear that both individuals were knowledgeable about the potential risks and benefits of different approaches to payment security. The final message from Mazumdar included a signature indicating that she sent the message. In addition, ZmnSCPxj noted that a receiver-provided partial route is no different from the final point the sender would have targeted if they knew exactly who the receiver is. This suggests that the two individuals may have been discussing specific details of a payment system or protocol.
