One more 'market' I'd love to brainstorm on is a hypothetical (for now):

If I am a Product Manager at Truist, Bank of America, Chase, etc tasked with researching and looking to adopt lightning technology at the firm, what would that process look like? Are there articles, how-to's, best practices - research on what others have done, reasons to adopt - and analytics on volume, fees, capacity? What other products and services are other competing banks using? What would my relationship be with merchants in this new system?

I don't claim to have any answers here and there are a lot of conversations I need to get started, but I think these types of questions will be top of mind for many financial firms and banks over the coming years...
