And there is the interesting question of what to do if there is a
discrepancy: which one is correct?

Indeed, the good thing about Namecoin is that you cannot take down a
domain and the bad thing about Namecoin is that you cannot take down a
domain... (I forgot to renew my Namecoin name, lost it to a "domainer"
without any possible recourse; in the end, he stopped renewing and I

Also, currently, most of blockchains rely *only* on the security of
your private key. Lose it, you cannot change your domain. Have it
stolen, someone else controls your domain. Because Mr Smith is clearly
