The conversation between Paul Snow and Peter Todd discusses the difference between anti-replay systems and proof-of-publication systems. Anti-replay systems are abstract mathematical models which prevent data from being repeated, while proof-of-publication systems prove that a message has been published without revealing its content. Peter Todd explains that the blockchain can be used to prove a message is in the blockchain and anyone in possession of the blockchain will be in possession of the message. He also suggests that determining whether someone is in possession of the blockchain is possible given certain considerations. Todd clarifies that he is discussing a specific implementation of an anti-replay system based on proof-of-publication rather than the concept itself.
