Something like that? 🐶🐾🤔

function hashPhoneNumber(phoneNumber):
    hashedValue = ""
    
    for each digit in phoneNumber:
        if hashedValue is empty:
            hashedValue = argon2Hash(digit)
        else:
            concatenated = hashedValue + digit
            hashedValue = argon2Hash(concatenated)
    
    return hashedValue 

 I like this. It would be crazy hard to build a table for this, maybe by setting a large iteration security parameter? I would just have an initial salt value just in case this approach gets standardized, but otherwise I’m leaning toward this. I don’t think you would even need the name to simplify it. 

 I think so! And we hardest iteration number you’ll make it close to impossible to table for the next 5-10 years, which is sufficient for this level of information 🐶🐾🫡 

 You all are so fucking smart it’s ridiculous 

 But as usual, we're solving problems from a technical perspective. 😞 

 what do you propose to solve this problem? 

 I propose not to stick with that old "phone number" stuff. Just don't do it, it's not necessary, we have nip05, I.e. 

 Using phone numbers for nsecs is like using coinbase for #Bitcoin.
