How do you actually verify a "track record" before trusting someone with your money?

Curious how this community thinks about trust/verification problems in general — not just in my space (forex), but anywhere someone claims a track record (traders, freelancers, agencies, etc.).

I've been building in the forex space, where the standard "proof" is literally a screenshot of a trading account — easy to fake, easy to cherry-pick, no way to independently verify. It made me think about how many other industries still run on unverifiable claims by default, and how few platforms actually build verification into the product rather than bolting it on as an afterthought (or not doing it at all).

For those of you building trust-sensitive products — how are you handling verification? Is it structural (like pulling data directly from a source of truth), or more manual/review-based? Would love to hear how others have approached this.
