The blockchain, charted

[azeteki]

Updated and added a few more charts.

A few 'experimental' charts are up at the following link: https://azeteki.github.io/charts/test



These ones might be a little inaccurate as I haven't fully tested my moving average routines. They should be close enough for rendering though.

Nice work!

Updated for block 332749 2014-12-03 21:29:57.
Apologies for the delay. I have been away attending to various worldly matters.
Some of the charts may look a little odd as I have not had time to adjust the axes.

Not really understand this chart. The coinbase reward only can be 50 or 25 at this time. Why there are other value?

Transaction fees are part of the coinbase transaction.

As shorena says.

Strictly to my understanding the coinbase can (presently) be anything _up to_ 25 + sum of all transaction fees.

A miner can produce a block with a coinbase of 5BTC and it will be valid. It is just not really an economically sensible thing for them to do.

Alright. I understand now. But it's really hard to believe that someone make such high fees transactions. Would you please show me the hash of that kind of tx/blocks please? I want to have a look into them.

Probably messed up.

Its indeed rare and usually - at least from what I read - by accident. Some reported they got high fees back from the miners.

Thanks. I think it's caused by accident. I heard about that someone has got his fees back from asicminer's pool.

[azeteki]

Yes. Most (all?) of these huge fees are caused by user error. People mucking around creating raw transactions, or coding bad wallets.
When creating a transaction by hand, the difference between inputs and outputs is given to miners as a fee.
A naive hacker can easily use a 50BTC input and assume that paying 3BTC to an address results in 47 remaining at the old address. Not so - the remainder of 47 goes off to mining land.

Updated charts for block 334725.

The most interesting changes recently to me are the leveling off of difficulty, and the continued increase in average block size. Blocks are roughly 375KB on average now, up from 225KB six months ago.

I have not yet bothered to create a 2015 page as there wouldn't really be much data yet. For now 2014 follows through to January.

As a side note, if anyone happens to have a host I could use that would be very much appreciated. Bandwidth usage should be utterly minimal.
The entire site including all graphs is about 500KB at present.
