[p2p-hackers] .p2p domain

Agreed on it not going anywhere anytime soon. I think they haven't been
clear on what problem they're trying to solve. If it's to prevent
government seizures of the domain, I'd suggest that be built into the
existing DNS infrastructure in a backwards-compatible fashion. Ideally
this would be part of DNSSec (though I don't think it is) as something like:
1) When the domain is registered (and renewed), record the new owner's
public key in a big TXT record.
2) When the domain's DNS record is changed in any way, sign it with that
public key. (This means only the owner can actually update the DNS record.)
3) On the client (or recursive DNS server) side, cache a domain's public
key (if available) until its registration expires. (The "TTL" for the
key is independent from the TTL of the record itself.)
4) When renewing the record, refuse any unsigned change, or change whose
signature fails.
5) (This is the big one) If a domain is signed, when the domain record's
TTL expires, don't flush the cache -- just attempt to renew. If you
can't renew, keep the old values. (This one is costly as it means you
essentially never flush signed domain values from your cache.)
The goal is to ensure that even if the ICANN, Verisign, your registrar,
and the USG all conspire against you, your domain still continues to
function to a large degree.
Furthermore, even if you were to do some P2P DNS approach (which I think
should just be called DDNS), it should again be a fallback to regular
DNS. Basically, in the above scenario, only search the P2P network if
it turns out that the registrar has an invalid record. In
99.99999999999% of cases, normal DNS will be correct, faster, easier,
more reliable, more efficient, etc. DDNS should be used 0.00000000001%
of the time. But its existence will prevent anybody from trying to
seize domains in the first place, so it's OK if it's only used in very
extreme scenarios.
