We're always looking for ways to implement blockchain technologies on Internet.bs, but there are hurdles. On the domain side, we'd love to see all registrations on the blockchain, but that would require a significant philosophy change for ICANN. We think it's inevitable, but have no direct input on ICANN policy. On the payment side, blockchain seems like an obvious future, but taxation and money-laundering hurdles have prevented us from going all in. As soon as we find a product that appeases the finance team, we'll get working on an implementation.
