< p > [1] Requires support in higher-level applications. These systems are not aware
of the existence of namespaces/TLDs at the protocol level.< / p >
< p > [2] Blockstack Core destroys the underlying blockchain token to pay for
registration fees when there is no pay-to-namespace-creator address set in the
name’s namespace. This has the effect of making the blockchain miners’ holdings
slightly more valuable.< / p >
