Blockchain.info - Bitcoin Block explorer & Currency Statistics

[organofcorti]

I'd like to request a csv or json of all block data similar to:

http://blockchain.info/blocks/$time_in_milliseconds?format=json

but by start and finish dates instead. I realise this will require a large amount of bandwidth, so maybe a compressed file, bittorented? It would be a fantastic resource for those of us who can't get bitcoin-abe going on macs.

I'm glad to see you've got a Windows Phone 8 app in the works.  I switched from Android when WP8 came out and have been missing the Blockchain.info app.

piuk, do you think you could add a chart that plots what can be seen here?: http://statistics.ecdsa.org/

There's no need for the animation, a static current chart would do.

Can do. But what is the definition of unspent? Literally the value of coinbase transactions which have never been spent?

Yeah, it means the bitcoins that were only issued and not moved since. All the bitcoins that moved since their issuance you plot on the graph when they must the last time.

Hi   hazek,

I had requested this too. See: http://blockchain.uservoice.com/forums/152743-general-ideas/suggestions/3177586-new-chart-for-addresses-without-activity

Hope piuk add it.

Yeah, it means the bitcoins that were only issued and not moved since. All the bitcoins that moved since their issuance you plot on the graph when they must the last time.

Or in other words: The coinbase transaction creates coins at a certain block chain height. Every other transaction moves them to a new block chain height.

block 100: coinbase 50Ƀ -> A (add 50Ƀ to "100")
block 200: 50Ƀ of A -> 29Ƀ to A, 10Ƀ to B, 10Ƀ to C (ignore input to A, B, C, fee. Just remove 50Ƀ from "100" and add them to "200")
block 300: 10Ƀ of B -> X, Y (Move the 10Ƀ of B from "200" to "300")

The graph shows, when coins move that were moved last at a certain time. It gives a very interesting insight beyond your bitcoin hours destroyed. For example you can see how in 07/2011 many addresses received coins that were not moved ever since. Unfortunately the y-axis is clipped and not log Combine this chart with the bitcoin price and you get insights on how people that bought/earned/mined coins at $17 are willing to sell/spend/… at $4 for example as you can see how specific regions melt off over time. Also see for example how the very early blocks get spent 10% in parallel during the 2011 sell offs, while the newer coins are not touched that much. This implies that at least the owners of these coins know each other and coordinated their sale or it was just one of the 10% miners of the first year that moved all his coins.
I hope you find the time to also make an animated version of this chart with even higher granularity as this is at least great fun to speculate about

Also congrats to you and your 100k wallets

Edit: I would remove the green (more or less constant) and red (redundant) lines, use a log scale, and draw the initial value of each bar green, coins that moved last week red, last month blue, last year yellow, earlier black. So for each pixel that you book from "100" to "200" you don't delete it at "200" but turn it red, one week later you turn it blue, …

Edit: Ha! You can make it static! Draw all inputs + coinbase black and mark pixels with the time stamp that they got removed at. Removed following 4 years, 2 years, 1 year, 6 months, 3 months, 6 weeks, 3 weeks, 10 days, 5 days, 2 days, … Edit: Downside would be that pixels one year before the latest block get a different color than younger coins, so relation is harder to read.

I give up Without animation I see no chance to accurately give insights for all the history. Very readable would be the inverse of this last suggestion. Draw the "now" bar green, the yesterday-bar blue (for the input), the next 2 red (for the input), … and if you moved value from yesterday to now, color a respective part of "yesterday" in today's color green. This way I could quickly see at which time frames coins were last moved that go into today's, last week's, last month's, … transactions. To analyse which coins went into January 5ths transaction I would need to change the point of reference though as I could not distinguish coins from the day before from coins from 4 days before.

Was playing around with the charts and stats on Blockchain.info and thought this was interesting so will share it here:



Shows % of transactions that are carried out by Blockchain.info wallets. Shows use of Blockchain.info is steadily growing.
If you exclude the 100 most popular addresses (Satoshi dice etc.) then it's even more apparent, maybe 50% of the transaction activity due to Blockchain.info users.

Wonder if the eventual release of v0.8 of the Qt client will move some of the activity back away from Blockchain.info?

While creating custom single-recipient outgoing transaction, in both FireFox 13 and Chrome 24.0.1312.56, two of my wallets show

"Insufficient funds"

message and quote less than 30% of the actual listed wallet Final Balance as available for sending. Receive Money
panel values add up to the Final Balance correctly. Have not encountered this problem up to 10:10am ET today. Should I be worried?

Thank you BlockChain devs for the great service!

piuk, I have a couple of privacy questions.

Let's say I enable notifications but then after a while I disable them. My question is, after I turn them off, any new key pairs I generate, can blockchain.info see the Bitcoin addresses and tie them to my email I had previously notification enabled to?

Also, is using an email for sending backs in anyway diminishing the privacy of my Bitcoin addresses?

Thanks in advance for taking the time and answering these questions!

Searching for transactions has stopped working.

For instance:  http://blockchain.info/search?search=a511bea3b5dc09609c4853d817cde909fdcdc06cc9558500f155ca821d0d511b shows:



and the blockchain.info home page, with a list of recent blocks.

It seems that the whole website is offline.

Looks fine to me.  Just searching for transactions doesn't work.

I think something is majorly wrong as I get a decryption error when attempting to login.

I keep having issues with my wallet where I can't send anything due to "Insufficient Funds".

When I try to send it says "Getting unspent outputs" and then gives me an error:

"Insufficient funds. Value Needed 0.581 BTC. Available amount 0.0000005 BTC"

It's been like this for several hours and I have had it happen several times before, what's up with this?

I am also currently having problems sending from my blockchain.info wallet.

When I try to send, I get the message: "Insufficient funds. Value needed XXX BTC. Available amount xxx BTC"

I have well over the amount needed to send.

I see no errors in the Javascript console.

Just out of curiosity, have you tried using the transaction type "Custom" instead of "Quick Send"?  That way you can select which inputs are used and you can even set the fee to 0 (or whatever value you wish).    That might help to resolve your issue.

I tried the Custom transaction at your mention of it, but that didn't work. I tried different addresses, different amounts, with and without a miner's fee, but still no joy. 

I get the same "Insufficient funds..." message even though I have more than enough BTC in my account to cover the transaction.

You could try to delete the address and restore it by re-importing the private key (but first make a backup).

Hey,

I installed the new android app (https://twitter.com/blockchain/status/298277650865197057) but it doesn't seem to update with my transactions so I'd like to revert to the old one until it's a bit more stable.

Does anyone have the old APK file anywhere so I can reinstall?

Cheers,

Will
