Transaction

j"1LAnZuoQdcKCkpDBKQMCgziGMoPC4VQUckM<div class="post">The theymos/nanotube design is much more heavyweight than my design, in terms of how much data it stores in the block chain.<br/><br/>My design stores the domain name plus a couple of nameserver IP addresses (say, 50 bytes) for an everlasting registration.<br/><br/>The theymos/nanotube design needs much more data: the initial registration, the regular renewals, and the possibility to include actual DNS records themselves up to 520 bytes. There's talk of the renewals being required perhaps as frequently as every 2000 blocks, and certainly no more than every 52000 blocks.<br/><br/>Over 10 years, the theymos/nanotube design might store anywhere between 600 bytes and 120,000 bytes per domain name.<br/><br/>I'm starting to think that an everlasting registration really is the way to go. In the DomainChain design, the registration would not be affected by block chain compaction, since compaction only affects spent transactions. If you transfer a DomainChain registration, or modify its name servers, all of the necessary information is contained in the latest transaction, which will remain unspent until the registration is deliberately modified. However, the theymos/nanotube design requires a sequence of transactions (registration, extra fee, DNS record, ...) where only the last transaction in the sequence remains unspent.<br/><br/>I think users will be uneasy about having to renew every 2000 or even 52000 blocks. Having to remember to renew, in order to avoid losing your registration, is bad enough. But block generation rates are variable, so that you won't even know for sure when your renewal falls due. Unpredictable renewals are not something that would make me feel good about using such a system for my domain name registrations. I can see many accidental domain name losses occurring under this system.<br/><br/>Obviously there needs to be a business case made that non-expiring domain names will work. But there also needs to be a business case made for the renewal process of the theymos/nanotube design.</div> text/html
