Also, if I am grossly misunderstanding things please feel free to correct me. Is there a way to deterministic generate H? Further explanation: * With bitcoin addresses we have BIP32 that allows us to generate a Master Private Key, transform it to a Master Public Key and then use that Master Public Key to generate a series of addresses. We can generate addresses without the use of the private keys. * With LN we generate a random value S and hash it into H and distribute that and then finally distribute S in order to close the channel. SO, my question: Is there a way to deterministic generate H like you can generate addresses with a Master Public Key without revealing S to the generator and still being safe to use S to close the channel? (Hopefully I am not just confused and talking bullshit here) John -------------- next part -------------- An HTML attachment was scrubbed... URL:
