[Satisfactory] Is it a chain of headers rather than a chain of blocks?
The page showed up fairly well on the following Google searches:
- headers chain vs block chain bitcoin
- headers chain
- block chain headers [Rank 6, what the heck?]
There are about a thousand pages describing how blocks are chained, so
even though I wrote the accepted answer (and I'm happy with it), I also
don't think this is "far better than other available resources." (For
all the searches above, the block chain section that I wrote for the
Bitcoin.org developer guide ranks higher.)
I also agree with Nick that ODell that the question title could
definitely be improved.
[Satisfactory] What exactly happens when a node detects a double spend?
Non-matching searches, no results in first two pages
- bitcoin double spend
- bitcoin core double spend
- bitcoin double spend drop
- bitcoin double spend confirm
- bitcoin node double spend
- bitcoin double spend keep
came up fairly often in the search results.
I think this question and answer are excellent for being specific and
clear, but it "requires oddly specific search terms to find," so I'm
grading it satisfactory.
[Needs Improvement] Is there a local wallet for Ripple?
Non-matching searches, no results in first two pages:
- ripple wallet
- local ripple wallet
- download ripple wallet
came up in every search result, although it describes something
different and may be out of date (I don't follow Ripple).
The Ripple.com downloadable client
also came up in most searches and provides, I think, the best resource.
Because the "answer is no better than what can be found elsewhere," I'm
ranking as needs improvement. Improvements could be further describing
the security and privacy benefits of the downloadable Ripple client, or
describing why it took so long for the Ripple project to create such a client.
Also, any contraindications for using the downloadable client would be nice.
[Excellent] Which bitcoin script forms should be detected when tracking wallet balance?
Non-matching searches, no results on first two pages:
- bitcoin wallet detect
- bitcoin wallet output
- bitcoin wallet scriptpubkey
- bitcoin wallet pubkey script
- bitcoin wallet script [page 2]
- bitcoin wallet script match [page 1, near top]
This is an important question for wallet and other program creators,
it's clearly worded, and Nick's answer is clear and concise. I also
think it will show up in search results for the most commonly used terms
even though there are some negative results above. It's "well-written
and has a clear, comprehensive answer that is far better than other
available resources," so I'm rating excellent.
I'll amend this post when I get to the rest (this is a lot of work!).
Edit: not going to finish. Hopefully 4 reviews is enough.
