The Financial Action Task Force recently recommended a set of compliance guidelines for crypto exchanges. One in particular looked at the 'travel rule' requiring exchanges to verify and keep records of users identities when sending between exchanges. This article shares some of the companies dealing with the response to this recommendation.
I found the company CipherTrace's TRISA one of the better solutions because it has no associated costs, looks to obtain as much privacy as possible and will likely define the standard across all exchanges.
Will be interesting to see what the best solution will be regarding compliance and regulations.
