I find the screen width far too wide for my notebook display. I'm constantly scrolling back and forth.
Is it maybe possible to have an alternate style option (css chg maybe) that would suit a narrow layout? I'm sure there must be quite a few notebook users who can't handle non-wrapping wide layouts.

Otherwise, great! I like the visual style.

It should be a little better now at smaller resolutions.

It'd be nice to print more technical details. Viewing script contents in particular is a helpful feature of blockexplorer.com

Scripts should now be displayed (I am using Bitcoinj for this). If the script is strange then it will attempt to print it as a string for example http://pi.uk.com/bitcoin/tx-index/5719188/9740e7d646f5278603c04706a366716e5e87212c57395e0d24761c0ae784b2c6 (Not condoning the content, this was the only example i could find).

Yeah I thought I'd test my MySQL cluster by deleting data on one of the nodes. Turns out it couldn't recover. I can't remember why it seemed like a good idea at the time  Undecided, but it should be all reimported now.

As for the csv data, I'll be adding an api sometime soon.

Great... I'm out of bitcoins Smiley what is your paypal?

Thanks, No Need Smiley If you could link to the site from anywhere that would be great.


The year graph is interesting. By far the largest peak of activity if right at the peak market price, looks like one of the early adopters stopped the rise by cashing out.

Days destroyed:

Thanks! You're doing a great work here Smiley

Thanks, Glad people find it useful.

Destroyed bitcoins lacks threshold, like 1 week or month. I think putting 1 week threshold will filter out noise (pool payouts etc).

What I mean, do not include transaction if its input is less than x time old.

PiUK, how hard will be to implement it? What do you think?

I could see this being useful, I'm calculating it now.

http://pi.uk.com/bitcoin/charts/bitcoin-days-destroyed-min-week
http://pi.uk.com/bitcoin/charts/bitcoin-days-destroyed-min-month
http://pi.uk.com/bitcoin/charts/bitcoin-days-destroyed-min-year

It will probably take all night.

Finally got round to adding bitcoin days destroyed:

http://pi.uk.com/bitcoin/charts/bitcoin-days-destroyed-cumulative?timespan=180days&showDataPoints=false&daysAverageString=1

Please could someone double check my formula:

Quote
days destroyed for one block =

for every transaction
   get the timestamp of the owning block in seconds (t1)
     for each input
       get the value of the previous output (v1)
       get the timestamp of the previous output's block (t2)
       daysDestroyed += v1 * ((t1 - t2) / 60 / 60 / 24)
 
I don't know if Abe is calculating it in a similar fashion, but for me it is very slow (takes roughly 10 mins for per 24hour period)

Added search by ip. For example if you lookup eligius's posh pool ip you can see their payouts http://pi.uk.com/bitcoin/ip-address/78.47.187.255. Data coming for blocks soon.

About 75% sure his ip is 128.253.153.95. It's from cornell.edu so possibly you could ring the university, but i'm not sure they could/would do much.
1090  Economy / Web Wallets / Re: New block explorer type site needs testing / feedback on: September 13, 2011, 06:45:53 PM
I've added the a list of large recent transactions at http://pi.uk.com/bitcoin/largest-recent-transactions

Also i've rewritten a lot of the bitcoin networking code so my client can now connect to around 2000 nodes. I'm running two clients so have a pretty good chance at intercepting double spends.

Very well done!


Can you add timestamps to the transaction history of addresses?

I've added timestamps to the transaction themselves. Unfortunately due to the way my mysql tables are partitioned it's quite slow to lookup a block from a transaction so I probably won't be able to add timestamps to the transaction history.

I've also added the ip of the node who first relayed a transaction.
1095  Bitcoin / Bitcoin Discussion / Re: "BlitCoin": "unmasks one or both ends of a BitCoin transaction"? on: September 09, 2011, 12:20:45 AM
Just to confirm my own code changes...Are you logging the ip from the 'inv' or the 'tx' message?  I originally logged the 'tx', but realized that the 'inv' message comes first. Smiley

--E

Logging from "tx", i think your right it might be better to log from inv (although when the client asks for an inv item the response will come from the same node).
1096  Bitcoin / Bitcoin Discussion / Re: "BlitCoin": "unmasks one or both ends of a BitCoin transaction"? on: September 08, 2011, 11:48:33 PM
I've started recording ip's on my block tracker site. Currently connected to 600 nodes but don't want to increase the limit any further as bitcoind cpu usages gets too high.

http://pi.uk.com/bitcoin/unconfirmed-transactions

It will be interesting to to see whether any of these ip's are actually the transaction sender. A lot of them link to personal home pages and stuff.

When i collect enough data i'll use the frequencies of ip's associated with a given address to try and guess the owner.

+1 to notion of adding the Bitcoin DD (days destroyed) stat.

One other comment: where do you get $1000 / 2 years for 1 GHash? Is that approximately 50% depreciation per year on a rig which costs $1/MHash/s? Don't disagree with the number so much as interested in how you derived it.

The average upgrade cycle for gamers is somewhere between 18-24 months (can't find the link where i read it now). After two years old cards won't be worth running compared to the newer competition, there probably is some resale value which isn't calculated in.

What is the logic used to estimate the transaction volume?

Heres the method. Basically common transactions "1 in ->2 out" it takes the smallest value, ">2 in -> 2 out" it takes the largest, otherwise total all.

public long getActualBTCSent() {   
       if (blockIsMined()) {
          return 0;
         
      //If a transaction transaction has more than two inputs and two outputs we take the largest output
       } else if (nInputs >= 2 && nOutputs == 2) {
         return Math.max(getOut().get(0).getValue(), getOut().get(1).getValue());
      //If a transaction has one input and two outputs we take the smallest output
      } else if (nInputs == 1 && nOutputs == 2) {
         total = Math.min(getOut().get(0).getValue(), getOut().get(1).getValue());
         
      //None simple transaction total all outputs
      } else {
         long total = 0;
         for (Output output : getOut()) {
            total += output.getValue();
         }
         return total;
      }
}

Something wrong with bitcoinwatch. There has been a drop in hash rate, but not that severe http://pi.uk.com/bitcoin

Feature request: Show date/time on transactions.

The problem with this is transactions don't have a time associated with them when sent. So there are two options:

- Record the time my client receives the transaction (which would mean no times for old transactions)
- Use the timestamp from the block the transaction was included in (no times for unconfirmed transactions)

Which do you think would be best?

The money doesn't have to come directly from new investment now. If the volume of transactions processed increases the value of bitcoin as a product increases, which can be used to settle the deficit in future. The is not happening though
