It’s a very niche feature request for our customer base. We can look into standing up a process for supplying them, but the goal is to have LN just work and not have customers need to know what a pre-image is.
it would be similar to showing the block explorer link for on-chain payments. is that button not getting clicked?
Is there a website or service similar to nostr:npub18d4r6wanxkyrdfjdrjqzj2ukua5cas669ew2g5w7lf4a8te7awzqey6lt3 for onchain but one for Lightning that we could direct customers to with their LN invoice and preimage that has more info?
i think the preimage is only revealed to the nodes across the payment route. i'm not aware of a site that lets you validate preimages similar to mempool.space, but
sha256(preimage) == payment_hash
i think the point nostr:npub1t0nyg64g5vwprva52wlcmt7fkdr07v5dr7s35raq9g0xgc0k4xcsedjgqv is trying to make is that nostr:npub1cashappn03s3cl2ljsdntv0v28e2um5lgx4vjctqjt23pcwzjhsqmtdg5l users don't operate the node they're spending from and aren't provided either of the values above which can be used to prove a payment was made.
contrast this with nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5 connected to my own lightning node - i'm actually presented with both whenever i successfully pay any lightning invoice. i ignore them and go on about my day, but if the recipient ever disputed that i paid then, i could pull these up as evidence.
