Yeah, that's excellent. What would it look like if an orphan chain continued for a few blocks? Perhaps you can mention (in the Next block(s)) that it is "likely orphaned" http://pi.uk.com/bitcoin/block-index/383776/00000000000001df2ba97a1537c5a5ed26ce070be48501c6944fc7414d8de194 but now I'm just getting picky. It's already very clear and hugely useful!

piuk, your link to Deepbit is wrong. The link leads to deepbit.org which is wrong and the correct one is deepbit.net, and it sounds suspicious...you didnt try to phish me did you?

It should look something like your diagram showing the next block when the chains finally converge. Needs testing though as I don't know what would happen if an already orphan chain split again. Another good idea, will add it soon.

You caught me. This has all been an elaborate scam to phish deepbit passwords Roll Eyes  deepbit.com .net and .org all point to the same ip hosted by Hetzner Online.

I downloaded a copy of the block chain from http://sourceforge.net/projects/bitcoin/files/Bitcoin/blockchain/ and am getting some good data from it (still importing).

One chain fork does like it's been purposely crafted (maliciously or for testing?)

New features!

You can see how well a transaction or block has propagated through the network (or at least the nodes i am connected to). Known/Trusted nodes are listed in the order they were relayed not including the originating ip.

e.g.

For a transaction:

http://pi.uk.com/bitcoin/tx-index/11109374/5b04ffeb046f89a1d8739f8ff799b1c46c3345e0c4cc7a2e67d408f39879624a

For a block:

http://pi.uk.com/bitcoin/block-index/388174/000000000000047c8bcceeade127a3628ee8076454714dedf290fc52e1041072

Also you can see a list of nodes connected at

When I look at the latest block, I see no transactions. Is there a delay? http://pi.uk.com/bitcoin/block-height/148961

Nice, I see you now redirect to the block if there are no orphans.

The base http://pi.uk.com/bitcoin/ returns a 404.

Timestamps such as "13:56:51 09/10/2011" are both dyslexic and ambiguous. One can only guess from your -.com TLD that it's 10 September.

EDIT: Oh wait, I assumed incorrectly, you're using European, 9 October. Please use YYYY-MM-DD HH:mm:ss Zulu. The Chinese will thank you. Smiley

EDIT2: No, I assumed that I assumed incorrectly. But I was incorrect. You ARE using American notation: 20:10:39 29/09/2011 can only mean 29 September. ISO 8601 and UTC are our friends. Smiley

Thanks for the heads up on the 404. Personally dates seem most natural to me as hh:mm:ss dd/mm/yy but i've changed them to ISO 8601 anyway.

I've added a WebGL globe showing online nodes @ http://pi.uk.com/bitcoin/nodes-globe . You need chrome or to enable WebGL in safari or firefox. Use your show wheel to zoom.

If you want more accurate data countries and hostnames can be seem on http://pi.uk.com/bitcoin/connected-nodes

I'm also thinking of moving the site to it's own domain anyone got any good name ideas?

bitebi.com (bitcoin in pinyin) seems up for sale.

Don't really like bitebi. I've moved it to http://www.blockchain.info Simple & to the point, still open to new suggestions though.

http://www.blockchain.info is perfect!

By the way, I got the impression that your service could track relayed transactions even when not locked into a block (0/unconfirmed). I removed transaction fees from main.h and sent a tiny (0.005 BTC) transaction. The fact that I can't see it means what? 1. you won't display the transaction until it's in a block, 2. no other nodes have relayed the transaction, 3. nodes have actively rejected it (somehow), 4. or....?

It should accept it but other nodes won't relay it so you'll have to push it directly to one me (or to eligius https://en.bitcoin.it/wiki/Free_transaction_relay_policy who should in turn relay it to me)

Apologies for the down time, back for now but might be down again for a few hours tomorrow. Should be much more reliable after that.

It's just my feeling or Bitcoin pools stats are completely wrong? Afaik you're detecting pools by IP, which won't work. Many pools don't have opened port 8333, for example. And your observed IPs (e.g. deepbit) are also wrong - those IPs are balancers, not mining backends and they're also subject of changes during attacks etc.

Probably only parsing website stats is a feasible way how to get sane pie chart of hashrate distribution.

Nice job!
One question: why older transactions have no date/time ?

Transactions only have a received time if my node was online at the time it was made. Otherwise the timestamp from the for block it was included first in the best way to estimate the time.

It's just my feeling or Bitcoin pools stats are completely wrong? Afaik you're detecting pools by IP, which won't work. Many pools don't have opened port 8333, for example. And your observed IPs (e.g. deepbit) are also wrong - those IPs are balancers, not mining backends and they're also subject of changes during attacks etc.

Probably only parsing website stats is a feasible way how to get sane pie chart of hashrate distribution.

The site has been up and down for the past few days which messes up the stats. It is advantageous for mining pools to be feel connect so even if they don't accept incoming connections eventually they will connect to me. It doesn't matter if they are balancers or not if deepbit's mining nodes are still behind them, which ip do you think is incorrect?

How can you be sure the pool is reporting the correct has rate?
