把世界上所有工作量证明仲裁系统都塞进一个数据集，是扩展不起来的。
比特币和 BitDNS 可以分开用。用户不该为了用其中一个而被迫下载两个的全部。BitDNS 用户大概也不想下载接下来几个不相干的网络塞进来的所有东西。
各网络需要有各自的命运。BitDNS 用户可能完全自由地加各种大数据功能，因为域名注册商不需要很多；而比特币用户可能越来越严苛地限制链的大小，好让大量用户和小设备都能轻松用。
担心用比特币安全买域名的恐惧是假问题。用比特币换其他不可抵赖的商品很容易。
如果你还担心，密码学上可以做到无风险交易。双方在两边都摆好交易，当双方都签了交易，第二位签名者的签名会触发两边同时释放。第二位签名者没法只放一边不放另一边。
英文原文
Piling every proof-of-work quorum system in the world into one dataset doesn't scale.
Bitcoin and BitDNS can be used separately. Users shouldn't have to download all of both to use one or the other. BitDNS users may not want to download everything the next several unrelated networks decide to pile in either.
The networks need to have separate fates. BitDNS users might be completely liberal about adding any large data features since relatively few domain registrars are needed, while Bitcoin users might get increasingly tyrannical about limiting the size of the chain so it's easy for lots of users and small devices.
Fears about securely buying domains with Bitcoins are a red herring. It's easy to trade Bitcoins for other non-repudiable commodities.
If you're still worried about it, it's cryptographically possible to make a risk free trade. The two parties would set up transactions on both sides such that when they both sign the transactions, the second signer's signature triggers the release of both. The second signer can't release one without releasing the other.
