Damn, that happens if I do the overview as an afterthought. Fixed :-) Real time (last 24 hours, last week, last month) are in the pipeline, just need to find the time to implement access to the collector from the webpage. -- Christian Decker On Wed, Nov 27, 2013 at 8:35 PM, Mike Hearn wrote: >

Hey Christian, Could you sort the snapshots by date? At the moment they're kind of in a random order. Sometimes I wish we had real-time stats too but this is a great start. On Mon, Nov 25, 2013 at 8:27 PM, Christian Decker < decker.christ...@gmail.com> wrote: > Thanks Mike for the Tip :-) > >

Thanks Mike for the Tip :-) I will definitely extend the calculations to include a size-normalized version. As for transaction propagations, being much smaller the measurements tend to be much noisier, but given enough samples we might be able to reconstruct some of the system parameters. Good id

Hi Christian, Cool - thanks for posting - agree, that it would be nice to normalize the results with block size - so divide by size and: 1. see if there is a correlation (we all presume there still is) 2. plot the delay graph as e.g. normalized to the averaged blocksize or lets define a "standard

This is great, thanks for doing it. Tip sent your way. Graphs of how propagation data change over time would also be helpful (as well as raw data so we can calculate overhead per kilobyte and so on). I know there are only two days worth of data, but for future, it'd be good. I think the next part

Sure thing, I'm looking for a good way to publish these measurements, but I haven't found a good option yet. They are rather large in size, so I'd rather not serve them along with the website as it hasn't got the capacity. Any suggestions? If the demand is not huge I could provide them on a per use

Since this came up again during the discussion of the Cornell paper I thought I'd dig up my measurement code from the Information Propagation paper and automate it as much as possible. The result is the Network Propagation page on bitcoinstats.com (http://bitcoinstats.com/network/propagation/). It
