Nope there is no contradiction. Again you haven't really thought about how this works. You are guaranteed to know who sent you your HTLC because the payment is settled through the channel. You cannot cloak this in any way. You only need to ddos the lightning network so it won't record their HTLC when it expires. There is no need to ddos them, though I would argue it would be equally easy to do. And so while the other party will eventually see the secret on the block chain, they can't get their HTLC unlocked on the network before it expires. And the lightning network has already been easily ddosed! We will see it happen more often if the lightning network ever gets bigger. This isn't some hypothetical situation.

> ddos the lightning network so it won't record their HTLC when it expires this is not even a thing. lightning network is collection of independent nodes, there is no registry of payments and channels, every node keeps their own record. > And so while the other party will eventually see the secret on the block chain, they can't get their HTLC unlocked on the network before it expires. why? if a party is stuck in a payment and especially if they notice they are getting attacked - they will take steps to mitigate. the moment commitment with secret is broadcast and in the worst case - the moment it gets confirmed on chain the other party will know the secret and can unlock their htlc. the risk is essentially the same as with deep reorgs - very low because those are very rare events. and the hassle is most definitely not worth the value of a stolen micropayment, which is the primary purpose of LN.
