My design for DomainChain builds on many of the ideas expressed here already. My main contribution is to remove "generation" from the design. It turns out that relying only on transaction fees makes everything very much simpler, and makes it easy to piggyback DomainChain onto Bitcoin.<br/></div><br/>Nanotube and I have been working on a DNS spec that is quite similar to yours. We had hoped to have a private RFC period, but since your proposal is so close, we decided to just publish what we have now.<br/><br/><a href="http://privwiki.dreamhosters.com/wiki/Bitcoin_DNS_System_Proposal">http://privwiki.dreamhosters.com/wiki/Bitcoin_DNS_System_Proposal</a><br/><br/>Some sort of expiration is required, preferably a short one (the 52,000 blocks used currently in this spec is probably too big). Having a short expiration requires everyone to rebroadcast their messages, which solves two problems at once:<br/>- With an expiration of <i>x</i>, you can build a complete DNS database by downloading only the most recent <i>x</i> blocks. Having an unlimited expiration would require you to download the entire block chain, which will eventually become several terabytes in size.<br/>- Spent transactions more than <i>y</i> blocks deep can be completely forgotten from the network. The value of <i>y</i> is currently unknown, but I expect it to be between 5,000 and 52,000. Messages need to be rebroadcast at least this frequently to stay alive if you want to use the convenient one-coin-per-domain system.<br/><br/><div class="quoteheader">Quote</div><div class="quote">If they receive coins that are associated with a domain name registration they will see them as coins.</div><br/>You can't receive non-standard transactions if you don't know the format (even if it just has some OP_DROP data). Normal clients will ignore such transactions.</div> text/html
