That's fantastic! May I suggest you change the map_canvas dimensions? You've got the United States, S. America, Africa, and Australia squarely in there (by default), but you cut off half of Europe, Canada, Russia, and heaven forbid all of Greenland. Think of the polar bears!

Should be a little better now. Polar bears are still out in the cold. Roll Eyes

Another potential use for this data: Today two blocks were generated at height 153715.

http://blockchain.info/inv/00000000000007c2b8380f991b3b36e8152c79e16434fcb6b7f0b498fa359f14

Block 000000000000003b1aa4d6d6171b6a6973471139a7cfaa6897b7501104c089c0 only propagated to 1% of the nodes while block 00000000000007c2b8380f991b3b36e8152c79e16434fcb6b7f0b498fa359f14 propogated to over 100%. From that data if your node had received the lesser propagated block then there was a high chance of it becoming orphaned.

No, I'm trying to show that a) they're heavily correlated b) There seems to be a direct relationship between the price bottom and transactions per day c) This graph can be used to estimate how much air (that is, speculation) there is in the exchange rate.

Ok try and add it to the site when i get chance.

Your site is often down... 2 out of the 3 times I tried to use it today got me at the cloudflare page.

Had a problem with tomcat segfaulting, seems to be fixed now.

I'm curious what you're using to determine which pools found blocks...considering you've posted multiple blocks as found by BTC Guild that were not, and multiple blocks not found by BTC Guild as ones we have Smiley.

I'm a method similar to Dam Kaminsky's proposal, recording the first node to relay a transaction as the transaction's origin. As it says on the pools stats page this isn't always 100% accurate.

I have added live network propagation maps @ http://blockchain.info/inv/${hash} . You can use this tool to help determine the origin or a transaction as well as to measure how well it has propagated through the network. If "First Relayed" and "Most relayed" match that ip is almost certainly the owner of a transaction e.g. http://blockchain.info/inv/9b35b2956bb9a98dd573d1154c84b68518d47fff57c09c061106440754224b37.

If they are not the same but geographically very close together e.g. http://blockchain.info/inv/f631f8d4153797fdb5b0b78514af9e126fa6607d106d56e9d2a584a494186a1d then the originator is probably the "most relayed" node.

to determine the owner of a block look at the mining pools list look at which pools relayed first. For example BTC guild is almost certainly the owner of this block http://blockchain.info/inv/0000000000000a39d6754b7aa1fa78d6a67481d16531ceb34b0df890a28fe0f2

It works best in Safari & Chrome, which have web sockets enabled (not tested on i.e.). Relay data is removed after 24 hrs.

Interesting graph, you are trying to show their is a direct relationship between market price and number of transactions? I personally don't believe this to be true. correlation != causation.

Looks like Eligius has their clock set 1 hour 10 minutes into the future, and you are using the block time instead of the received time for the age...
That block is also completely missing from http://blockchain.info/blocks/1320972380607.


I'm going to leave as the block time as there could be a delay between that and the received time. The block you mention is an interesting anomoly as the extra hour pushed it to the next day http://blockchain.info/blocks/1321058780607.

PiUK, any chance you could implement a graph like this dynamically on your site? I used you graphs as a base and whipped this one up.

Hey there,

Is your code open source? Any plans for that?

It doesn't seem to support searching for address prefix. Typing 18tVFm7C into the box should complete to this address:

http://blockexplorer.com/address/18tVFm7CjQgeKk4BPwu1cYGHZyAFwwriuk

as it does on blockexplorer.com, but it actually does something completely different. Searching by address prefix is useful for checking physical bitcoins.

I will probably open source the backend at some point. I have forked the mainline bitcoin client to allow several machines to operate as if they were running a single bitcoin node e.g. they share the same blockchain and load balance transaction and block validation. I don't have any plans to open source the front end.

This is not implement, it should say not found not sure why it takes you to an unrelated address. How would collisions between addresses with the same prefix be handled?

Also, would be great to have another graph. The number of addresses with unspent outputs.  Grin

I'm not sure exactly what this would illustrate. As more coins are coming into production the figure will almost certainly increase regardless of wether there is an increased number of holders.

On a different note, as the site seems to be running well, I've removed the connection limits on the bitcoin nodes. Currently connect to over 4000 unique nodes (approx 10,000 connections due to overlap) is this a record?



It's another way of getting an idea of how much bitcoin is getting real world use. In addition to the daily transaction counts.

Quite nice number of connections there Smiley

I'va added options to view all data and log scale. Log scale is a beta feature of high charts so its not perfect, sometime the graph won't render or the y axis scale is a little messed up.

Thank you!  There's still one little bug left but I'm happy with just being able to see the graphs for all time in logarthmic Smiley It would be great if you can fix the date scale that's shown on the bottom as well as the magnitudes shown on the left.

I love the different graphs you have available on your site. However, sometimes I feel like I'd like to see more history than just a year. Could you add an option to see the data for the whole lifetime of the network? Especially for the number of transactions graph but other would be nice too. Also, an option for logarithmic scale to accompany that would be great Grin

Btw what's dns for your node? telnet blockchain.info 8333 does not work...

The website routes through cloudflare so which I don't think will work with telnet. I'm keeping the ip's of my nodes hidden. Node 1 has a static ip which you can probably find fairly easily, Node 2,3,4 change ip every few hours.

Nice website but has some serious issues with uptime and also the payment notifications do not seem to work !

Yeah it has been very flaky the last week. It was running on my home ADSL connection but has now been moved to a new datacenter so it should be better from now on.
