Are there any archives or databases that chronicle the transactional history of high-end domain names, such as gold.gold, that can be accessed for research purposes?

Unfortunately, a thorough search on NameBio and DNPrices yielded no results, suggesting a gap in the availability of such information.

NameBio and DNPrices are great resources, but they're limited in their scope. They're like looking at a small piece of a much larger puzzle. To get a complete picture of the market, you need to look at other sources, like industry reports, academic studies, and even social media platforms.

But even then, you're going to run into roadblocks. Many high-end domain sales are private, and the parties involved may not want to disclose the details. It's like trying to get blood from a stone – it's just not going to happen.

So, what's a researcher to do? Well, you can try to gather data from other sources, like domain registrar reports or ICANN data. You can also try to interview domain investors and industry experts to get their insights. But at the end of the day, you're going to have to accept that some information is just not publicly available.

Tracking down significant public domain transactions requires a bit of sleuthing online. Unfortunately, there isn't a centralized database or a comprehensive list where you can find all these deals neatly organized. Additionally, most private transactions remain under the radar, as they aren't disclosed to the public.

You could try contacting the domain name brokers or marketplaces that specialize in high-end domain name transactions, such as Sedo or Uniregistry, to inquire about their sales data and transaction history.
Keep in mind that some of this information may be proprietary or confidential, so be prepared to negotiate access to the data or offer something in return, such as a research collaboration or a case study.
