transaction fees - any stats?

[k]

Hi

does anyone have any stats or know how to get stats on the transaction fees.

things like
average fee per block over time
average fee per transaction
average # of transactions per block with fees
highest fee value for a block
etc.

I know if you look at the block explorer for each block you can see fee data for that block but I don't see a way to query data for fee in the block explorer. (Not a complaint of block explorer by the way, it's a super resource)

I'm interested to see the trends of fees over time. Has there been an increase in total fee value? Is that increase in line with the growth of other stats like the # of transactions, growth in value of bitcoin, etc.?

I know it's a long way till the block reward halves to 25 but curious to see what the trends are in fees now. Or do people think that fees will remain pretty insignificant until the block reward halves and then the reduced reward will cause miners to be far more demanding about fees to try to replace lost income due to the block reward reduction?

Code:

{
...
  "tx":[
    {
...
      "out":[
        {
          "value":"50.14350000",
        }
      ]
    }
  ]
}

Get that number and subtract 50. Find the guy who wrote a script to crawl the block chain and offer him some bitcoins to do it.

I'm curious about this data too

I'd also wondered about the transition to transaction fees.  It's not clear that it'll be an easy transition.  So I took about 2000 of the most recent blocks from the block chain and I'm not seeing any real change in transaction fees over the last 2000 blocks.  The average is 0.075 BTC in fees per block.  50% block come below 0.03 BTC, 80% below 0.1 and 95% below 0.3.  I don't have transaction figures yet or any stats for more than 2000 blocks.  That'll have to be another night, I've already spent too much time on bitcoin tonight.

This is awesome.  I didn't go back far enough, they are on the rise...

great charts ThomasV.

If I'm looking at it right for recent blocks tx fees/day are ~20 BTC. Very rough estimate say ~200 blocks/day (I know it should be 144 blocks if we assume 10 minutes between blocks, but block creation has been faster than that recently) - that gives a very rough ballpark number of 0.1 BTC in fees/block. Not far off smell's 0.075 BTC/block average (difference probably from actual block creation has been >200 blocks/day recently).

good to see the trend is increasing in the Bitcoin Report charts.

I actually downloaded Python yesterday and was thinking of teaching my self how to write a script to create a csv file with the block # and total tx fee in that block # as suggested by PLATO. Never used Python before and haven't coded anything since some C++ classes I did in college over 10 years ago but have been thinking for a while to learn some new skills and this seemed like an interesting project.

It doesn't surprise me that there are no (or few) transaction fees yet.  The blocks still include generated coins.  This effectively charges all other owners of bitcoins to give 50 BTC to the generator.  You've got to look on coinbase transactions as equivalent to governments printing money.  The total money supply is inflated, which reduces the value of all the other coins in circulation.  Why then should people pay transaction fees as well?

I would expect transaction fees to be negligible until the coinbase gets to zero.  It doesn't matter what my expectations are anyway, while miners find it profitable, they will stay in existence.

It's certainly not worth worrying about now.

I contracted Jessica_lily on IRC to write a script to do this - we've been playing keyboard tag but I think she finished it up. Will report back when we have a graph

Also there were a couple block chain crawlers ITT: http://forum.bitcoin.org/index.php?topic=9300.0
