Hi guys, I am working on a project that requires me to figure out the lightning channel balance. I am wondering if anyone here has the code of a prober?

Hi guys,

does anyone know the best way to figure out the time and date of a specific HTLC commitment transaction?

I am learning lightning network and I encountered an issue.

Purpose: We need to prove someone owns a certain amount of BTCs.

When the BTCs are in Bitcoin's original network (layer 1). If a person claims he owns 1BTC, we can simply have the person digitally sign a message for the related addresses (to prove ownership) and then we can check through a bitcoin node (using an indexer) to find the BTC balance as of a specific block height.

The problem is that with the proliferation of the lightning network (or other off-chain state channels), we now are unable to simply “go to the blockchain” to find the balances at a specific block height.

Given this person could have his lightning channels available stored on his own node, and this person is not objective (and could be lying). Is there a way to compile lightning channel balances from an objective source? What would be the best way to prove this person owns the BTCs while these BTCs are being used in the lightning network?
