I've created a proposal for a file that would replace the old "ripple.txt" way of reporting information about how you use the XRP Ledger. (For reasons including the fact that "XRP" isn't "Ripple"!)
If adopted, I expect this could be a key piece in how validator operators verify their identity, and may also be useful for client applications for various other purposes. (For example, if the owner of an XRP Ledger address is verified, client apps could show provided contact info or description alongside that address.)
For people who run validators or actively develop tools and applications on top of the XRP Ledger, your feedback is very important because this spec doesn't serve a purpose unless you find it useful! If you fit that description, please take a look and provide your input on the draft specification here:
