In the examples you sent, the blockchain-dns is just a browser plugin<br>
method, so not really DNS. EMCDNS seems to be full on DNS but I've never<br>
heard of it before now, thanks for sending.<br>
<br>
My opinion is that:<br>
<br>
- in certain situations, blockchain lends itself to DNS as being more<br>
distributed and more redundant than some of the TLDs out there. This is<br>
attractive to me because it would be more resistant to standard DDoS<br>
attacks (but then the size of the blockchain would determine<br>
vulnerability to 51% attacks)<br>
<br>
There are also scaling issues, I would never expect or posit something<br>
like .COM to be moved onto a blockchain.<br>
<br>
But I've long wondered if there is a hybrid option where we have a<br>
blockchain where one can pin DNS RR's can act as a kind of "lookaside"<br>
for mission critical domains - but that would necessitate resolvers<br>
being aware of it.<br>
<br>
- the crypto space is here to stay, and the addressing scheme they all<br>
use are begging for a naming system, the same necessity that gave rise<br>
to DNS exists in this space and has not been solved yet.<br>
<br>
There was Namecoin, as P.O.C but was more about being a fully<br>
decentralized TLD without governance but as I've often remarked to these<br>
crypto types "believe it or not, you actually *want* some kind of<br>
governance".<br>
<br>
Ethereum Name Service (ENS) seems out in front right now, I attended the<br>
first ENS WG meeting in London UK last summer and there is a *lot* of<br>
momentum here. They are incorporating DNSSEC into ENS validation and are<br>
looking for full interoperability with legacy DNS.<br>
<br>
The .XYZ registry is working with ENS WG to integrate .xyz domains into<br>
ENS so that <a href="http://example.xyz" rel="noreferrer" target="_blank">example.xyz</a> can be used as an ethereum contract or wallet<br>
address. See:<br>
<br>
<a href="https://medium.com/the-ethereum-name-service/how-to-claim-your-dns-domain-on-ens-e600ef2d92ca" rel="noreferrer" target="_blank">https://medium.com/the-<wbr>ethereum-name-service/how-to-<wbr>claim-your-dns-domain-on-ens-<wbr>e600ef2d92ca</a><br>
<br>
- I have been thinking that it may be a good idea to add a new DNS<br>
RRType that can be used to reference "Blockchain Resources", along the<br>
lines of a NAPTR record, so a "BCR" or "BCRPTR" which would reference<br>
things like<br>
<br>
* which crypto-currency / blockchain<br>
* which address type within that blockchain<br>
<br>
If anybody is interested in this please let me know, I've been<br>
s-l-o-w-l-y organizing a working group to draft a spec proposal for<br>
this, I've never done anything like that before.<br>
<br>
I gave a short talk on where I see this all going at the ENS WG meeting<br>
last year:<br>
