There are a few registrars that allow registering for 100+ years. I personally would not do this, as the domain is just contractually rented and not really owned. Adding to this no registrar can actually register a domain for more than 10 years upstream so that means I have to believe the individual registrar, reseller or Wordpress in this case will be solvent for 100 years. To have that confidence I would need to see the legal agreements they have with multiple corporations and legal entities that allow their assets and staff retention to persist after bankruptcy. Very few companies go through that kind of trouble <i>and cost</i>. I worked for one that did and some of us were individually named in the contract to be employed by the successors.<p>What I would probably do instead is have trust managers or family members or offspring of friends appointed in a legal trust to continue the registration of the domain if it were that important. This frees up the option to move the domain to any registrar based on whatever needs may arise. If the family members lose interest or bad decisions I made in the past taint my legacy then they can stop wasting money on the domain. But that's just my personal preference. I'm sure investors love the idea. Perhaps the low friction option of paying for 100 years and just taking the risk is worth it to some.<p>As a side note an electric chisel with a tungsten carbide bit and a rock cliff or cave made out of extremely hard rock can persist messages for a very long time. a.k.a. old school blogs. I would wager that someone here could combine that chisel with a frame and some servos to automate carving some beautiful calligraphy into rock walls and caves.
